Ratings: 4.4 out of 5 - more than 70 global ratings

Scientist Alex Tarnava revolutionized H2. With molecular hydrogen, concentration is everything. Drink HRW tablets generate 12.4 PPM, more molecular hydrogen than any other brand. By a long shot. Third-party analysis validates their hydrogen concentration claims. These are the exact tablets commonly used in research. For example, this July 2021 study found that Drink HRW tablets outperformed caffeine after sleep deprivation. Their blog is a great resource for all the latest hydrogen water research.

To further maximize potency, Drink HRW’s patented formula keeps more of the molecular hydrogen in the water (where most brands quickly evaporate off).

2. Dr. Mercola H2 Molecular Hydrogen Supplement: Best Value

Ratings: 4.4 out of 5 - more than 1,700 global ratings

Backed by one of the biggest names in natural health and longevity, Dr. Mercola’s molecular hydrogen tablets deliver the largest dose of H2 for the price. As an added bonus, Mercola’s molecular hydrogen is soy-free, gluten-free, and GMO-free. Judging by the ingredients list, the magnesium included is likely the highly bioavailable magnesium malate. These tablets are produced in the USA.

Mercola's Molecular Hydrogen tablets create higher concentrations of up to 8 ppm in 480 mL of water. And it does it in an open container without the need for a cap or lid.

H2 Molecular Hydrogen uses pure elemental magnesium as its carrier and provides you with approximately 80 mg of magnesium per tablet. So, you receive also highly bioavailable magnesium for a healthy brain, muscles, cells, kidneys, and heart.

For general purposes, they’re hard to beat. If you’re new to molecular hydrogen and want to test it without breaking the bank, Dr. Mercola’s H2 tablets are a perfect introduction.

Dr. Mercola H2 Molecular Hydrogen Supplement Review
This was very different than other supplements I have used. The tablet dissolves quickly and I have been using it before exercising.

3. Quicksilver Scientific H2 Elite Tablets: Best Absorption 

Ratings: 4.3 out of 5 - more than 300 global ratings

Quicksilver Scientific (QS) makes some of the highest-quality, best-absorbed supplements. At 10 PPM, for a while QS produced the strongest tablets on the market—until surpassed by Drink HRW.

Formulated by Dr. Christopher Shade, Ph.D and manufactured in the USA, H2 Elite is the contaminant-free choice. Their product is: vegan, soy-free, gluten-free, allergen-free, non-GMO, and cGMP certified.

Quicksilver Scientific molecular hydrogen has an extra organic acid in its formulation to further increase PPM and absorption. H2 Elite does not require their tablets to dissolve in a closed container like most products on the market.

Each tablet delivers 80 mg of magnesium malate in a proprietary hydrogen base.

Drop one tablet in a cup of pure water (12-16 oz). Wait for the tablet to dissolve. Stir if necessary, drink immediately. Repeat up to 3 times daily. Does not need a closed container and dissolves in less than two minutes.

Sure there may be slight after flavor so i just brush teeth after. But it promotes a great overall energetic feeling that’s last. Dissolves easily (quicker in room temp water). Love this product. Been using on/off for years.

4. Hydrotab Molecular Hydrogen


WHY HYDROTAB H2?: Because molecular hydrogen is so small, it can not only penetrate the blood/brain barrier, but also pass easily through cell walls into the nucleus where it is utilized by mitochondria for healthy cell signaling, cell metabolism, and healthy gene expression

INCREASE ENERGY AND FOCUS: Hydrotab Molecular hydrogen helps stimulate energy metabolism to experience more energy, healthier metabolic function including healthy weight maintenance, mental alertness, hydration and re-hydration, and focus. Fight age-related energy loss and find increased energy as you age.

Hydrotab supports production of the body’s own in-house antioxidants such as Glutathione and SOD. Unlike popular antioxidant therapies, Hydrotab selectively targets only the very worst free radicals, promoting a healthy balance of the antioxidant/free radical ecosystem.

INFLAMMATION: Molecular Hydrogen acts as a gene signaling molecule to help balance the body’s inflammation system by up or down regulating pro-inflammatory proteins in your body.

HELP YOUR HEART AND LIVER: Hydrotab helps reduce oxidative stress at the cellular level in support of cardiovascular health on multiple levels. Research suggests that molecular hydrogen helps support liver health while supporting glucose metabolism and insulin sensitivity.

Hydrotab Review
As someone who works out on a regular basis, adding hydrogen to my water regularly has helped with muscle fatigue recovery. I also work long hours and I've noticed an increase in alertness throughout the day. Finally, I've also noticed a decrease in allergy symptoms, which a great plus.

This product was recommended to me by my daughter. The purchase price caught me by surprise, but I figured I’d give it a shot. I have a very stressful job and get migraines here and there, but I have not had a migraine in probably 2 years. When the product arrived (I ship to my work), I decided to take one, as I was starting to feel a cold coming on and I hadn’t slept more than 3 or 4 hours a night in several months, plus the migraine was just starting.

I drank my water with the tablet in it and within about 30 minutes the migraine subsided and I had energy. I know this isn’t listed to help with migraines, but the overall “better” feeling I had after taking this the first day was worth the price. It’s been ~2 weeks since I started taking this and my energy is up, which helps me get more work done and in turn reduces stress. All of this combined to help me sleep more (averaging 5 hours per night the past 2 weeks). I am a believer. Great product.

6. True Nano H2 by H2 Universe

Molecular hydrogen, H2, in your body becomes a powerful beneficial antioxidant and as a supplement helps fight many health problems and the effects of aging. Getting a daily dose of hydrogen, from capsules, assures you that your body gets an everyday boost and therefore promotes longer life with greater energy, health, and focus.

- Boost Energy
By promoting an anti-inflammatory response, acting as an antioxidant, and activating the body's own immune defense, True Nano H2 can help aid in recovery times and improve physical endurance. For the young, this means better physical fitness; for the elderly, it means vitality and less fatigue.

- Simple and Effective
Each convenient capsule can be taken anywhere and produces up to 20 milliliters of H2 that is absorbed into the blood without loss—unlike H2-saturated water which quickly loses potency through evaporation. Taken one to three times a day, you can help your body fight free radicals and thus prevent many health problems.

This is the first time I've tried this kind of supplement. Pills are small and easy to swallow. No smell or taste that I noticed. I believe I had a minor reduction in some muscle achiness and a bit of an increase of energy when using this supplement. I did not have any negative side effects from the supplement.

Testing the Potency of Molecular Hydrogen Tablets (PPM)

Warning: testing should only be done in a laboratory setting.

You can manually test H2 tablets to ensure that you’re getting the full advertised dose. The process is done by adding a testing solution (called H2 blue) to a glass of molecular hydrogen water.

Here are the steps to testing the PPM of your molecular hydrogen tabs:
  1. Add 1 H2 tablet to a glass of water
  2. Fill a small glass (or vial) with 6 mL of hydrogen water
  3. Add 10 drops of H2 blue testing solution to the 6 mL of hydrogen water
  4. Stir
  5. Repeat steps 3 and 4 and count total drops until solution remains blue.
Every 10 drops equals 1 PPM of molecular hydrogen. So if you add 30 drops, stir, and the solution stays blue, that means your tablet contains less than 3 PPM of H2.


a. Molecular Hydrogen Tablets Side Effects

Considered very safe, molecular hydrogen water itself does not have any known side effects. However, tablets and H2 water generators can cause side effects from inactive ingredients and the off-gassing of other compounds.

The following are some possible negative effects of molecular hydrogen tablets:
  • Gastrointestinal issues: Some people may experience stomach discomfort, nausea or diarrhea after ingesting hydrogen-rich water.
  • Allergic reactions: Some people may be allergic to hydrogen-rich water or hydrogen gas and may experience an allergic reaction.
  • Interaction with other medications: Molecular hydrogen tablets may interact with certain medications, so always consult with your doctor before taking them.
Even though some of these effects are generally mild and temporary, you must take note that hydrogen tablets are considered a dietary supplement, not a drug. Therefore, it is not regulated by FDA, and the quality and purity of tablets may vary among different brands. 

b. Does hydrogen water really work?

Hydrogen water works in both the healthy and sick. Most notably, it is a powerful selective antioxidant, capable of acting on any cell, organ and tissue. It’s considered one of the top anti-aging supplements and is being researched for use in the treatment of 170+ different diseases.

c. What does molecular hydrogen do for the body?

Molecular hydrogen reduces oxidative stress and inflammation throughout the body. Since inflammation is at the root of most chronic disease, molecular hydrogen reverses brain fog, neurodegeneration, mimics the effects of fasting, and slightly increases energy.

d. How much hydrogen water should I drink a day?

Your ideal hydrogen water dose depends on the use case. It’s recommended to pulse molecular hydrogen usage 1-2 times per day, in the morning and evening. Follow the product recommendations.

e. Does hydrogen water give you energy?

Molecular hydrogen water users often report greater energy. It works by protecting and turbocharging mitochondria (cellular power plants) from damage, keeping energy high. In fact, greater energy is one of the most commonly reported effects.
