In this interview (below), Russel Reiter, Ph.D. — a world-class expert on melatonin — discusses some of the biological activities and health benefits of this important molecule. With some 1,600 papers to his credit, as well as three honorary doctor of medicine(1) degrees, he’s published more studies on melatonin than anyone else alive. Melatonin 101 Melatonin is one of the most important antioxidant molecules and certainly the most ancient, as it has been part of biological life for over 3 billion years. It's present in prokaryotes, which are bacteria, and even in plants. In the human body — aside from having direct antioxidant effects — it also stimulates the synthesis of glutathione and other important antioxidants like superoxide dismutase and catalase. Reiter continues:  “Melatonin has been here forever ... and its functions have evolved. It has learned to work successfully with other molecules during this three-billion-year evolution. One of the molecules...

In this interview (below), Dr. Stasha Gominak, 1   a neurologist and sleep coach, explains the curious synergy between vitamin D deficiency, a changed microbiome and poor sleep. I met Dr Gominak at the American College for the Advancement in Medicine’s annual meeting in 2019 in Nashville. Her lecture was about ways to improve your sleep. I thought I was aware of most of them, but the connection between vitamin D and sleep surprised me. Gominak’s research suggests lack of vitamin D causes impairment in your brain stem’s ability to produce normal sleep. So far, she’s treated more than 7,000 patients with her innovative “sleep repair” approach. She’s also published scientific papers on her theories. Vitamin D Deficiency Linked to Sleep Disorders Gominak had no interest in vitamin D, initially. She was fascinated by sleep, and was trying to figure out why so many young and otherwise healthy patients were having such trouble sleeping. Many also had sleep apnea. Over time, it be...

Castor oil has become one of the most viral “ancient remedies” in modern wellness culture. Across YouTube , TikTok, and alternative health blogs, it is promoted as: A detoxification accelerator A lymphatic system activator A natural immune booster A deep sleep enhancer A collagen stimulator A hair regrowth solution A scar dissolver A gut reset tool A way to wake up with a flatter stomach overnight The claims are often framed in scientific language — referencing EP3 receptors, prostaglandins, lymphocytes, and molecular cascades. It sounds compelling. But how much of it is real — and how much is mechanistic storytelling layered onto traditional oil use? This article provides a rigorous, evidence-informed breakdown. Understanding the “Nighttime Redemption Cycle” Many castor oil videos begin with a powerful hook: Your body enters a biological cleaning window during deep sleep — and you can amplify it. This framing leverages something real. During deep sleep: The glymphatic system increase...

How Dementia Risk May Be Detectable 10–20 Years Before Symptoms Appear Dementia rarely begins with memory loss. By the time confusion, disorientation, or personality changes appear, pathological processes in the brain have often been developing silently for decades. The study , published in Alzheimer’s & Dementia, focused on the glymphatic system, a recently discovered brain-cleansing mechanism that flushes toxins and waste products from the brain. The research suggests that three measurable biological systems may reveal dementia vulnerability long before clinical diagnosis: The brain’s glymphatic (waste-clearing) system Sleep architecture, especially deep slow-wave sleep Circadian rhythm strength and timing Together, these systems form a tightly integrated neurobiological maintenance network. When disrupted chronically, they may accelerate neurodegeneration. When supported, they may help preserve long-term cognitive resilience. This report synthesizes current findings into a ...
