What is Aging?
Longevity Medicine will become the New Primary Care |
Biological Age vs Chronological Age
But maybe your doctor says you have the physical conditioning of a 21-year-old. This would be considered your biological age, regardless of how many years ago you were born.
Your chronological age will always be an easy-to-determine number, while your biological age depends on a number of variables that can change on a continuing basis.
What is chronological aging?
It’s also a primary risk factor for chronic diseases, mortality, and any impairments to bodily functions, such as hearing and memory.
What is biological aging?
Also known as physiological or functional age, biological age differs from chronological age because it takes into consideration a number of factors other than just the day you were born.
The actual number comes down to different biological and physiological development factors. Some of these include:
- chronological age
- genetics (for example, how quickly your body’s antioxidant defenses kick in)
- lifestyle
- nutrition
- diseases and other conditions
While chronological age is a factor, you may not end up having the same biological age as your chronological age. For example, if you’re a 28-year-old male who doesn’t exercise, only eats high-fat foods, and has smoked five packs of cigarettes per day for the last 10 years, it’s likely you would have a biological age of greater than 28 years.

Diet and Lifestyle for Anti Aging
- First, maintaining a healthy weight throughout life is pivotal for healthy aging and longevity, mirroring the benefits of lifelong, moderate calorie restriction in today's obesogenic food environment.
- Second, the specific types or food sources of dietary fat, protein, and carbohydrates are more important in influencing chronic disease risk and mortality than their quantity.
- Third, some traditional diets (e.g., the Mediterranean, Nordic, and Okinawa) and contemporary dietary patterns, such as healthy plant-based diet index, the DASH (dietary approaches to stop hypertension) diet, and alternate healthy eating index, have been associated with lower mortality and healthy longevity. These patterns share many common components (e.g., a predominance of nutrient-rich plant foods; limited red and processed meats; culinary herbs and spices prevalent in global cuisines) while embracing distinct elements from different cultures.
- Fourth, combining a healthy diet with other lifestyle factors could extend disease-free life expectancies by 8-10 years.
1. Avoiding Sugar and Ultra-processed Foods
2. Best Anti Aging Diet: Mediterranean Diet and Cruciferous Vegetables
Caution: What are the nutrients of concern for vegetarians and vegans? Vitamin B12 and K2. Anybody who is eating a vegan diet or a vegetarian diet or just a mostly plant-based diet should be taking vitamin B12 and K2 supplements. Vitamin B12 is only found in significant amounts in animal products and fortified foods, and a deficiency can cause anemia, mood changes, or permanent neurological damage. Plant-based diets may also be low in vitamin D, omega-3 fatty acids, and minerals like iodine, selenium, iron, and zinc.@lewis Biochemist Jessie Inchauspé aka @glucosegoddess_ shares incredible hacks in this episode to minimize glucose spikes without cutting sugar out of your diet - have you listened yet? #sugar #sciencetok #aging #reverseaging #glucose #glucosegoddess #jessieinchauspe #jessieinchauspé #biochemistry #nutrition #nutritiontips #healing #healingjourney #wellness #wellnesstips #healthandwellness #healthandwellnesstips #food #glycation #ageinreverse #nutritionhacks #biohack #biohackingsecrets ♬ Adventurer - Lux-Inspira
3. Avoiding Linoleic Acid and Vegetable Oil
Over the last century, thanks to fatally flawed research suggesting saturated animal fat caused heart disease, the LA in the human diet has dramatically increased, from about 2 to 3 grams a day 150 years ago, to 30 or 40 grams a day.
On a side note, do not confuse LA with conjugated linoleic acid (CLA). While most think CLA and LA are interchangeable, they're not. CLA has many potent health benefits and will not cause the problems that LA does.
Like other nutrition experts, study author Nilson agreed that a healthy, balanced diet should be based on fresh and minimally processed foods, when possible, in addition to avoiding ultra-processed foods.
“The continuity of the current trends with gradual increases in ultra-processed food consumption will increase premature deaths,” Nilson said, adding that his research highlights a need for a shift in policy around ultra-processed foods.
4. Avoiding Smoking and alcohol
“Smoking is one of the strongest risk-factors for every chronic disease, including heart disease and cancer,” says Susan Lakoski, M.D., associate professor of cancer prevention at MD Anderson Cancer Center.Smoking and secondhand smoke introduce harmful toxins to the body. There’s no such thing as a healthy smoker - especially when it comes to cancer prevention.
“The biggest myth I hear is that if someone exercises they can offset the negative effects from smoking, but that’s absolutely not the case,” says Susan Lakoski, M.D.
But it's not only smoking that's harmful. Chewing tobacco has been linked to cancer of the mouth, throat and pancreas.
Staying away from tobacco — or deciding to stop using it — is an important way to help prevent cancer. For help quitting tobacco, ask a health care provider about stop-smoking products and other ways of quitting.
5. Sleep
This is one of the most under-rated anti-aging strategies.
Research has demonstrated sleep is a crucial component of
a healthy lifestyle.
In a 2023 study (The Lancet), scientists looked at how the
relationship between sleep and exercise might impact
cognitive decline. Researchers from University College
London examined the association between physical activity
and sleep duration in 8,958 participants over 10 years.
The data were collected from the English Longitudinal
Study of Aging, during which participants were interviewed
every two years.
The researchers evaluated episodic memory using recall
tasks and verbal fluency using animal naming tasks. They
found that participants with lower levels of physical
activity and suboptimal sleep had worse performance on the
cognitive tests and those who slept the least exhibited
faster cognitive decline. Interestingly, the participants
who had higher levels of physical activity and shorter
sleep times also had faster rates of cognitive
decline.
Those who had higher levels of physical activity and slept
an optimal number of hours had the slowest cognitive
decline. Overall, the data suggested that higher-intensity
physical activity was not enough to mitigate the rapid
cognitive decline that is associated with insufficient
sleep.
Lack of quality sleep can also weaken immune function and
increase susceptibility to respiratory infections,
including the common cold, and chronic lack of sleep may
be associated with an increased risk of death (Prather
2015; Ibarra-Coronado 2015; Wilder-Smith 2013; Aldabal
2011).
Sleep deprivation is associated with elevated cortisol
levels, as well as higher daytime levels of inflammatory
cytokines including IL-1, IL-6, and tumor necrosis
factor-alpha (Aldabal 2011; Hirotsu 2015). A study in
individuals aged 61‒86 found even a single night of
partial sleep deprivation induced patterns of gene
activation associated with biological aging (Carroll
2016).
6. Stress Management
A big component of the longevity equation is the
management of stress.
A June 2022 study supports what immunologists have long suspected:
A key stressor to our immune system as we age may be
stress itself.
“Immune aging may help explain why older people tend to
benefit less from vaccines and why they have more serious
complications associated with infections like
COVID-19,” Erik Klopack, Ph.D., a lead author of the study and a postdoctoral
scholar at the Leonard Davis School of Gerontology at the
University of Southern California. “Our study suggests
that social stress may accelerate immune aging,” he said.
7. Exercise and Resistance Training
Another important factors in slowing sarcopenia is diet. As we age our appetite declines, so as we eat less we naturally reduce the amount of protein that we consume. To slow sarcopenia we need to keep our protein intake high, and as we are eating less this means that a higher proportion of the food we eat needs to be protein. It is also important to spread this protein out through the day over three or meals as this produces more muscle protein synthesis when compared to one or two high protein meals.
It is also important to get your vitamin D levels checked as you age since deficiency is common due to reduced sun exposure. As well as weakening our bones, low vitamin D results in weaker muscles and accelerated sarcopenia. A low vitamin D level can be easily rectified with supplementation. When was the last time you had your vitamin D level checked?
Being aware that sarcopaenia affects us all is the first step in combating its effects. The earlier you commence resistance exercise, the greater the benefits, but it is never too late to start. If you are new to resistance exercise or intimidated by the gym environment, talk to your local gym about some personal training to help you learn.
8. Social Support
Okinawa in Japan, Sardinia in Italy, Roseto in Pennsylvania, Loma Linda in California, Icaria in Greece and Nicoya in Costa Rica are some of the places with the highest proportions of people who live to be 100 years old.
All these places have the same thing in common. What is it?
9. Intermittent fasting, time restricted eating (TRE) and Calorie Restriction
Intermittent fasting is currently one of the most popular
nutrition programs around. Unlike diets that tell you what to eat,
intermittent fasting focuses on when to eat.
Limiting
the hours you eat each day may help you consume fewer calories. It
may also provide health benefits, including weight loss and
improved heart health and blood sugar levels.
There are
several forms of intermittent fasting, including a common form
called time-restricted eating.
Research overwhelmingly supports the notion that ditching the
three square meals a day approach in favor of time-restricted
feeding — can do wonders for your health. Contrary to modern
belief, your body isn't designed to be fed throughout the day, and
the near-continuous grazing that most engage in can have serious
health consequences.
Time-restricted eating is just what it sounds like. It's a form of
intermittent fasting where you eat all of your meals for the day
within a restricted window of time, ranging from two to eight
hours. That means you're avoiding food (fasting) for 16 to 22
consecutive hours. Eating within a four- to six-hour window is
likely close to metabolic ideal for most. As noted in the paper
"A Time to Fast," published in the November 2018 issue of Science:
"Adjustment of meal size and frequency have emerged
as powerful tools to ameliorate and postpone the onset of
disease and delay aging, whereas periods of fasting, with or
without energy intake, can have profound health benefits.
The
underlying physiological processes involve periodic shifts of
metabolic fuel sources, promotion of repair mechanisms, and the
optimization of energy utilization for cellular and organismal
health …
In general, both prolonged reduction in
daily caloric intake and periodic fasting cycles have the power
to delay the onset of disease and increase longevity."
Fasting, or reducing your calorie intake is also an excellent
method for indirectly boosting the body’s NAD levels. Fasting has
been shown to increase the levels of NAD+ and surtuins; the
proteins which have been found to slow the aging process.
While fasting is effective in increasing NAD+ levels, drastic
reduction in calorie intake or fasting can have a
counterproductive effect. There is also some speculation that
intermittent fasting or adopting a low carb-ketogenic diet may
also provide similar positive results.
Research also suggests that caloric restriction and fasting might be
helpful to give your existing so-called endogenous stem cells a
boost.
Fasting may also help reduce obesity-associated cancers. “There’s
a lot of obesity-associated cancers,” said Dr. Jason Fung, a
nephrologist and fasting expert. “There’s about 13 cancers that are well accepted that they are associated with
obesity; fasting might help decrease that.”
Fasting can potentially starve cancer cells. When fasting, the body uses fats and produces ketones for
energy. Cancer cells rely heavily on glucose, making them less
efficient at using ketones.
Additionally, fasting
reduces insulin levels. Elevated insulin levels are linked to
an increased risk of breast, prostate, and colorectal cancers.
Caloric Restriction
The goal of caloric restriction is to reduce total caloric intake
while maintaining optimal nutrition. This may be best accomplished
by eating a diet primarily composed of low-calorie, nutrient-dense
foods such as vegetables, fruits, legumes, nuts and seeds, and whole
grains; limiting intake of animal products; and avoiding
calorie-dense, nutrient-poor foods (Rizza 2014). Caloric restriction
in animals has been shown to prolong lifespan and delay aging, and
to confer a more youthful profile of T cells (Ahmed 2009; Fernandes
1997; Michan 2014).
Limiting the hours you eat each day may help you consume fewer calories. It may also provide health benefits, including weight loss and improved heart health and blood sugar levels.

Additionally, fasting reduces insulin levels. Elevated insulin levels are linked to an increased risk of breast, prostate, and colorectal cancers.
Best Anti-Aging Supplements
1. Vitamin D3, Omega-3 and K2
In addition, optimizing your vitamin D levels is one of the absolute best affordable strategies to slash your cancer risk.
Previous research found that a vitamin D level of 47 ng/ml was associated with a 50% lower risk of breast cancer (R). Further, researchers at University of California, San Diego School of Medicine reported that raising your vitamin D level to at least 40 ng/ml can slash your risk of all invasive cancers by 67% (R).
Many governments advise 400 to 800 IU of vitamin D per day, while many vitamin D researchers claim you need at least 2000 to 4000 units per day.
We would recommend to take at least 2000 units per day. The risk of excess accumulation of vitamin D is negligible with this amount. Make sure it’s vitamin D3, and not vitamin D2 – the vitamin D3 variant works better.
The study, published in The American Journal of Clinical Nutrition (Oct 2021), used data from a long-term study group, the Framingham Offspring Cohort, which has been monitoring residents of this Massachusetts town, in the United States, since 1971.
The research looked at 2,200 people who were monitored for 11 years for their blood fatty acid levels. The researchers found that omega-3 levels in red blood cells are very good mortality risk predictors. That means that higher levels of Omega-3 in the blood from regularly eating oily fish, increased life expectancy by almost five years.
This research comes a few months after a meta-analysis of 17 prospective cohort studies was published in Nature Communications. The analysis linked higher circulating omega-3 fatty acid levels to longevity. In a pooled analysis of the studies, participants in the highest fifth of combined blood DHA and EPA were 15 to 18 percent less likely to die from any cause over the follow-up period (median follow-up time is 16 years in these studies). Higher blood omega-3s were also associated with a reduced risk for death from cardiovascular disease and cancer.
Make sure you buy high-quality omega-3 fatty acid supplements, meaning that the omega-3 fatty acids are pure and have not oxidized much (having low “TOTOX” value).
2. B Vitamins and NAD Boosting Supplements
B vitamins include:
- B1 (thiamine)
- B2 (riboflavin)
- B3 (niacin)
- B5 (pantothenic acid)
- B6
- B7 (biotin)
- B12
- Folic acid
The epigenome is the intricate machinery that surrounds the DNA and that determines which genes are active and not. During aging, the epigenome becomes more and more dysregulated.
The older we get, the less NAD+ is present in our cells. Taking in NMN can increase NAD+ levels.
Various animal and lab studies show that NMN has beneficial effects on aging diseases and symptoms (R,R,R,R).
For example, long term administration of NMN mitigated age-associated decline in mice: NMN reduced the typical age-associated increase in body weight, improved energy metabolism, improved lipids in the blood and insulin sensitivity and ameliorated eye function (R).
NMN can also improve aging-related decline in fertility (R), improve bone health (R) and vascular health (R,R,R).
3. Glycine, NAC and Taurine
Low glycine levels also have been associated with various aging-related diseases like cardiovascular disease and with type 2 diabetes.
Glycine extends lifespan in different species (R,R,R,R).
Glycine has many functions in the body. It improves the epigenome (the machinery that determines which genes are switched on or off, a process that goes increasingly awry when we get older). Glycine especially improves the epigenome of mitochondria, the power plants of our cells (R).
Glycine also functions as a chaperone. Chaperones are small molecules that gently stick to and protect the proteins. That is important, because one of the reasons why we age is due to proteins accumulating everywhere inside and outside our cells, eventually hampering the proper functioning of our cells.
Glycine also reduces inflammation (R) and has many other beneficial effects, especially for the cardiovascular system. People with higher glycine levels in the blood had less risk of a heart attack (R), and glycine can protect the blood vessels (R).
By taking a glycine supplement, you can counteract this chain of events by making sure there's enough glycine present to fill up those glycine slots. As noted by Stephanie Seneff, Ph.D., (a senior research scientist at MIT for over five decades), "If there's lots of glycine, you're going to be much less likely to pick up glyphosate."
"Your body only makes 3 grams of glycine per day, and if you only consume around 2 to 3 grams of glycine from foods then it means that almost all of us are in a 10-gram glycine deficit every day," he says.
"… I think most people would benefit for at least 5 to 10 grams of glycine a day, which is, uh kind of a moderate amount … if you are eating a lot of muscle meat … or you're just interested in getting more of the benefits of glycine then you can take even up to 20 grams a day."
- Inhibit cancer cell growth
- Extend lifespan
- Lower levels of insulin, glucose and insulin-like growth factor 1 (IGF-1)
- Reduce liver damage after exposure to dangerous amounts of acetaminophen
- Reduce frailty
"NAC, the acetylated form of the amino acid cysteine, protects our brain by stimulating the activity of glutathione, which is a potent antioxidant that protects our mitochondria from free radical damage. NAC is also effective against viruses and it is used both for the prevention and treatment of some viral infections, including brain infections."
He added, "Conventional doctors use NAC to counteract the consequences of paracetamol overdose because it protects the liver from damage."
Kyriazis suggests the conventional dose is around 1000 mg to 1500 mg per day and says some doctors recommend taking NAC with vitamin C to prevent it from being destroyed in the body prematurely.
"500mg of NAC every morning is an effective dose for adults looking to use it daily as a longevity supplement," he explained. "It has an excellent safety profile and can be taken with any other supplements, including glutathione."
Researchers at Baylor College of Medicine also looked into supplementation with a combination of glycine and N-acetylcysteine (NAC), two glutathione precursors known as GlyNAC when taken together.

Treated mice also had less body fat (approximately 10% less at 1,000 milligrams of taurine per day) and higher energy levels. According to the authors, “Fat-pad weight divided by body weight percentage was dose-dependently reduced in taurine-treated mice.” Taurine supplementation also improved several markers of aging, including Senescence, Intercellular communication, Telomere length, Epigenetic changes, Genomic stability, Mitochondrial function, Stem cell populations and Nutrient sensing.
4. Magnesium and Molecular Hydrogen
Magnesium functions as a cofactor to hundreds of different enzymes, which need magnesium to function properly.
There are many ways in which magnesium deficiency can lead to accelerated aging. Magnesium is needed to build, maintain and repair DNA.
Magnesium reduces DNA damage and stabilizes the genome (R,R). For example, magnesium sticks to the DNA strand and stabilizes it, and it is also an essential cofactor for DNA repair proteins which need magnesium to function properly (R).
Magnesium can reduce inflammaging (low-grade inflammation that increases during aging). Low levels of magnesium have been linked to chronic low-grade inflammation, which is one of the drivers of aging (R).
Besides magnesium’s many effects on maintaining our cells, the mineral has various immediately noticeable effects. Athletes take magnesium to improve their physical performance, even when they are not magnesium deficient (R).
Magnesium supplements also improve sleep, and feelings of relaxation and wellbeing.
This is not surprising, given the important role of magnesium in the functioning of brain cells, such as excitation and neuronal metabolism.
Malate is often used in combination with magnesium to bring about health benefits, especially for improving energy and reducing fatigue.
It was also already discovered that hydrogen can prolong the life of stem cells by reducing oxidative stress (Biochem Biophys Res Commun. 2010).
5. Curcumin (Turmeric)
Cellular senescence occurs when cells stop dividing. As you age, senescent cells accumulate, which is believed to accelerate aging and disease progression (Source, Source).
Research demonstrates that curcumin activates certain proteins, including sirtuins and AMP-activated protein kinase (AMPK), which helps delay cellular senescence and promotes longevity (Source, Source).
Plus, curcumin has been shown to combat cellular damage and significantly increase the lifespan of fruit flies, roundworms, and mice. This compound has been shown to postpone age-related disease and alleviate age-related symptoms as well (Source, Source).
This may be why turmeric intake has been associated with a reduced risk of age-related mental decline in humans (Source). You can increase your curcumin intake by using turmeric in recipes or taking curcumin supplements.
6. CoQ10
Research suggests that levels of CoQ10 decline as you age. Supplementing with it has been shown to improve certain aspects of health in older individuals.
For instance, a 4-year study (2015) in 443 older adults demonstrated that supplementing with CoQ10 and selenium improved overall quality of life, reduced hospital visits, and slowed physical and mental deterioration (Source).
CoQ10 supplements may work by reducing oxidative stress, a condition characterized by an accumulation of free radicals that accelerates the aging process and the onset of age-related disease (Source).
Additionally, CoQ10 supplements may benefit heart health by reducing stiffness in your arteries, lowering blood pressure, and preventing the buildup of oxidized cholesterol in your arteries (Trusted Source).
7. Fisetin
Quercetin and Fisetin have been grouped together due to their
similar molecular structure, with only minor differences. Both
are flavonoids and senolytics.
Fisetin, a molecular cousin to the more popular Quercetin, is
also a naturally occurring substance found in fruits and
vegetables, such as strawberries, apples, grapes, onions, and
cucumbers.
Fisetin is a flavonoid. Flavonoids are substances that
give fruits and vegetables their bright colors (like yellow,
orange and blue) and play a major role in conferring the health
benefits that we get from eating more vegetables and fruits.
Fisetin
is probably most known for its impact on senescent cells:
studies showed that this substance can reduce the accumulation
of senescent cells (R). Fisetin is a senolytic, a compound that can clear away senescent cells.
Senescent
cells accumulate everywhere in the body during aging. Senescent
cells were previously normal cells that became too damaged.
Normally, when a cell is too damaged, it kills itself, but
senescent cells don’t do that.
Instead of dying, they
keep lingering around in the body.
Senescent cells
secrete all kinds of substances that damage the healthy
surrounding cells, like inflammatory substances (cytokines and
chemokines), substances that break down the glue that holds the
cells together (matrix metalloproteinases), and growth factors
that accelerate aging (R). Not only do senescent cells damage healthy surrounding
cells, but they also damage stem cells, which are the
foundational cells that create new cells, which build up and
repair our organs and tissues.
Reducing the senescent
cell burden can lead to reduced inflammaging (low-grade
inflammation that increases during aging) and enhanced function
of stem cells.
Substances that can eliminate
senescent cells are called “senolytics”. Fisetin is a
well-studied senolytic substance.
Fisetin versus quercetin
Besides fisetin, another senolytic is quercetin. Quercetin and
fisetin look very similar. However, fisetin seems to be the most
potent and safest of natural senolytics (Lancet 2018).
The conclusion of the researchers was the following:
“Fisetin had the most potent senotherapeutic effects in
several cell types in vitro and showed strong anti-geronic
effects in vivo”.
Quercetin reduces glutathione and inhibits sirtuin-6 and
NRF-2. All of these will hurt your longevity (see
this clip, 2:30).
Lifespan extension effects of fisetin
Scientists demonstrated that fisetin can extend median and
maximum lifespan in mice, even when taken late in a mouse’s life
(equivalent to 50 or 60 years old for a human) (R).
More than a senolytic: other anti-aging effects of fisetin
Fisetin has many other beneficial effects on the aging process
besides eliminating senescent cells.
For example,
fisetin inhibits the mTOR pathway (R), which plays an important role in aging and is where many of
the health benefits behind fasting are derived. Fisetin can also
reduce oxidative stress (R).
Fisetin can reduce inflammaging (aging-related
low-grade inflammation) by inhibiting pro-inflammatory enzymes
and substances, like lipoxygenases and NF-kB (R, R).
Interestingly, fisetin can also have various
beneficial effects on the skin. For example, fisetin can reduce
the formation of skin wrinkles and appearance of skin aging.
Fisetin also has a positive impact on brain functioning
and brain aging (R). For example, fisetin can improve memory formation in mice
(R, R).
Fisetin is a flavonoid. Flavonoids are substances that give fruits and vegetables their bright colors (like yellow, orange and blue) and play a major role in conferring the health benefits that we get from eating more vegetables and fruits.

Fisetin also has a positive impact on brain functioning and brain aging (R). For example, fisetin can improve memory formation in mice (R, R).
8. Vitamin C and Calcium Alpha-KetoGlutarate (AKG)
Vitamin C can help to maintain a proper epigenome, especially in combination with another longevity ingredient, alpha- ketoglutarate.*Umbrella review: An umbrella review, or a review of reviews, is a systematic review that only considers other systematic reviews as an eligible study type for inclusion.
Alpha-ketoglutarate is used by the mitochondria, which convert this substance into energy, but alpha-ketoglutarate has various other functions in the body.
Numerous studies show that alpha-ketoglutarate can extend lifespan in various organisms. AKG extended lifespan in C elegans worms (R) and fruit flies (R,R,R) and mice.
Alpha-ketoglutarate also plays a role in maintaining stem cell health (Nature 2015), and in bone and gut metabolism (R).
Calcium alpha-ketoglutarate is also involved in collagen production, can reduce fibrosis, and can thus play a role in maintaining healthy, youthful skin (R,R).
9. Resveratrol and Pterostilbene
The slight difference in molecular structure between resveratrol and pterostilbene provides a sound rationale for the superiority of pterostilbene. Pterostilbene should be more stable and bioavailable in theory, and preclinical studies so far validate the assumption.
10. Zinc
In a study in healthy older volunteers, daily intake of 45 mg zinc for one year resulted in a 67% reduction versus placebo in incidence of infections. Levels of tumor necrosis factor-alpha, an inflammatory cytokine, were also greatly reduced in those taking zinc (Prasad 2007). In a study of older individuals in nursing homes, residents with normal zinc levels had a significantly lower incidence of pneumonia compared with zinc-deficient individuals. Zinc-replete individuals also had shorter pneumonia duration and 50% lower usage of antibiotics, as well as lower all-cause mortality (Meydani 2007). A controlled clinical trial in aged individuals showed supplementation with 45 mg zinc per day for six months decreased plasma markers of inflammation, including IL-6 and C-reactive protein (Bao 2010).
Combining zinc with other important vitamins and minerals may also aid immune function. In a randomized controlled trial that enrolled 42 subjects between 55 and 75 years of age, those who took a multivitamin/mineral supplement containing 10 mg zinc and 1,000 mg vitamin C, along with other vitamins and minerals, for 12 weeks experienced fewer self-reported sick days and less severe symptoms than those who took placebo. The number of sick days decreased by nearly 65% with supplement use (Fantacone 2020).
Ideally, one takes 2 mg of copper per day.
Stem Cell Therapy for Anti-Aging
Despite the fact that there are many published studies on stem cell therapy for anti-aging, major media has been slow to report the findings.
The Vinmec Research Institute of Stem Cell and Gene Technology are exploring the use of MSC for male sexual dysfunction in a phase I/II clinical trial (NCT05345418). They are currently recruiting male subjects aged 50–70 years old with sexual functional deficiency. Treatment groups will receive two iv doses of 1.5 million cells/kg body weight spaced out by 3 months. Various biomarkers, testosterone levels, and sexual life quality information will be measured. The First Affiliated Hospital with Nanjing Medical University has an upcoming phase I clinical trial (NCT04706312) researching the use of amniotic mesenchymal stem cells (AMSCs) for the treatment of infertility is people with diminished ovarian response. Subjects will receive an iv injection of AMSCs and measurements recorded for ovarian function and in vitro fertilization such as stimulated follicles, number of oocyte retrieval, fertilization rate, etc. (ACS Chem. Neurosci. 2024)
Hormone Replacement Therapy
Hormone replacement therapy (HRT) for women has been a topic of much debate in recent decades. This is due largely to the fact that the Women’s Health Initiative (WHI) study in 2002 was halted prematurely because of a reported increase in the instance of breast cancer in women participating in the hormone replacement arm of the study. Thereafter, thousands of women were taken off or stopped taking HRT unnecessarily, despite the fact that many studies have debunked the WHI conclusions.
HRT & Breast Cancer: What’s the Connection?
One of the major flaws of the WHI was the confusion and fear it spread by projecting its results to all women receiving HRT. In the original study, more women who took estrogen plus progestin (E+P) developed breast cancer than those taking placebos.
Further research published in a 2013 article in The Journal of Clinical Endocrinology and Metabolism shows that breast cancer rates were actually found to decrease significantly with estrogen alone. Moreover, the article goes on to say that even though there isn’t a significant increase with E+P used together versus estrogen alone, for illustrative purposes, any increased risk of breast cancer associated with E+P originally publicized with the WHI trial is less than the risk conferred by obesity, being a flight attendant, and many other common exposures.
Another noteworthy difference which can play a role in breast cancer risk is the use of synthetic progestins versus bioidentical progesterone. Synthetic progestins, which were used in the WHI, are hormones which are synthetically produced, and thus different in structure from bioidentical progesterone. Bioidentical progesterone, while produced from a plant source, is structurally and chemically identical to the progesterone produced by the ovaries. Synthetic progestins mimic some effects of the natural hormone, but react differently with progesterone receptors within the body and are felt to be responsible for the increase in breast cancer seen in WHI. On the other hand, bioidentical progesterone does not increase, and may actually reduce the risk of breast cancer.
Can HRT Help Prevent Cardiovascular Disease in Women?
Cardiovascular disease is responsible for 1 in every 4 deaths in the U.S. It’s the leading cause of death in both men and women, and leads to more than 600,000 deaths across the country annually (CDC). It’s therefore critical that as the risk for cardiovascular disease increases with age, individuals find ways to optimize heart health.
HRT may not be prescribed for women primarily as a means for improving cardiovascular health, but this is indeed a powerful byproduct of the treatment. According to research published in the BMJ, women receiving HRT early after experiencing menopause had a significantly reduced rate of heart failure, myocardial infarction, and mortality overall. At the start of treatment, women on average were aged 50 and had been postmenopausal for seven months. Roughly half as many women using HRT experienced cardiovascular events compared to those in the control group. Additionally, these results did not correlate with an increased risk in any cancer [BMJ 2012].
Moreover, evidence shows that there is a clear benefit in using estrogen alone, with coronary calcium scores significantly reduced. This measures the buildup of calcium and other substances which can narrow or close the arteries, leading to cardiovascular issues. In particular, women under 60 who receive hormone therapy have a statistically significant reduction in coronary disease (Lobo 2013).
These aren’t the only positive outcomes of HRT, however. Hormone therapy has been commonly used as an osteoporosis preventative, which brings us to our next segment.
Testosterone injections are most often given by your doctor. The injection site is typically in the gluteal muscles in the buttocks.
TRT is an acronym for testosterone replacement therapy, sometimes called androgen replacement therapy. It’s primarily used to treat low testosterone (T) levels, which can occur with age or as a result of a medical condition.
But it’s becoming increasingly popular for non-medical uses, including:
- enhancing sexual performance
- achieving higher energy levels
- building muscle mass for bodybuilding
This is all part of a completely natural process that starts in your late 20s or early 30s.
This gradual decrease in Testosterone often doesn’t cause any noticeable symptoms. But a significant drop in T levels may cause:
- low sex drive
- fewer spontaneous erections
- erectile dysfunction
- lowered sperm count or volume
- trouble sleeping
- unusual loss of muscle and bone density
- unexplained weight gain
DHEA plays a critical role by serving as a counterweight to cortisol. Cortisol is an adrenal hormone with immunosuppressive properties, while DHEA may have direct immunostimulating properties: in a laboratory study of white blood cells from donors who were at least 65 years old, DHEA treatment reversed the age-related reduction of specific receptors on immune cells and increased immune cell responsiveness (Corsini 2005). Although DHEA levels decline dramatically with age, cortisol levels remain relatively constant, leading to an imbalance of these two hormones that is believed to contribute to immune senescence (Buford 2008; Buoso 2011).

Metabolic Manipulation, mTOR Inhibitors and Rapamycin
One particular strategy in mitochondrial medicine presently under study is metabolic manipulation. This approach is aimed at counteracting the deranged cell biological homeostasis caused by mitochondrial dysfunction, using dietary modifications or small molecule therapy. Cell biological alterations caused by mitochondrial dysfunction include increased reactive oxygen species production, enhanced lipid peroxidation and altered cellular calcium homeostasis. There are five principles of metabolic manipulation:- prevention of oxidative damage by reactive oxygen species,
- amelioration of lipid peroxidation, (
- correction of altered membrane potential,
- restoration of calcium homeostasis, and
- transcription regulation interference.
- Significant benefits in cardiovascular function with reversal or attenuation of age-related changes in the heart
- Beneficial behavioral, skeletal and motor changes compared with mice fed a control diet
- Reduced indicators of inflammatory, metabolic, and hypertrophic expression of cardiac tissues
- A decrease in cancer incidence
- Improvement of cardiac function (heart function)
- Improvement in bone marrow function (immune system)
- Metabolizes cellular fat stores (weight and body composition)
- Increases lifespan by inhibiting mTOR (slows down rate of aging)
- A highly-optimized diet
- Individualized power supplements
- A healthy sleep routine
- Stress management techniques
Does Metformin Increase Life Expectancy?
In humans, metformin has been in clinical use for over 60 years, studied extensively, has a high safety profile, and is uniquely positioned to intervene several crucial pathways responsible for aging and age-related diseases (Barzilai et al., 2016). As recommended by the American Diabetes Association, due to its glucose-lowering effects, metformin monotherapy is the preferred first-line pharmacological action against type 2 diabetes (American Diabetes Association, 2019).

Conclusion and Key Takeaways
The best way to promote longevity and overall health is to engage in healthy practices like consuming a nutritious diet, engaging in regular exercise, improving your sleep and reducing stress.While some research suggests potential benefits from supplements, hormone therapy, or even stem cells in slowing aging, these shouldn't replace core healthy practices. A well-rounded approach is key for optimal well-being.
Focus on Fundamentals:
- Nutritious Diet: Prioritize a balanced diet rich in fruits, vegetables, and whole grains.
- Regular Exercise: Aim for consistent physical activity, incorporating different types like cardio and strength training.
- Quality Sleep: Get enough restful sleep for optimal body and brain function.
- Stress Management: Find healthy ways to manage stress, such as meditation or spending time in nature.
Remember, supplements are not magic bullets. They should complement, not replace, a healthy lifestyle. Consult your doctor before starting any new supplement program to ensure safety and suitability for your individual needs.
Multi-Targeted Aging Solutions
Aging is a complex process with various contributing factors. Ideally, an anti-aging supplement should address these factors synergistically, meaning the components work together for a stronger effect.
- Epigenetics: Look for substances supporting a healthy epigenome, like alpha-ketoglutarate (AKG) and NMN.
- Mitochondrial Health: Consider ingredients like AKG, fisetin, and malate to support healthy mitochondrial function.
There's no magic bullet for aging. It's unlikely a single strategy will address all the complexities involved. The best approach for most people likely involves a personalized menu of strategies that combines a healthy diet and lifestyle with potential benefits from evidence-based supplements.
