Dr. Gundry, noted heart surgeon, authority on digestive health and the microbiome, and New York Times best-selling author, has done it again. The nutritional supplement company he founded, Gundry MD, has released a product called H2 Restore, that sent me down the rabbit hole of researching H2 (the chemical formula for hydrogen), its role in our bodies, and why we should consider a product that gives us easy access to “molecular hydrogen.” 

H2 Restore is designed to boost the power of the polyphenols in your diet, provide energy, aid in muscle support, and is good for cardiovascular health, joints, and metabolism. Although favored by elite athletes for recovery from intense exercise, the product’s benefits are suitable for anyone.

So let’s get a more thorough look at this supplement. In this H2 Restore review, we’ll briefly discuss those polyphenols H2 Restore amplifies, explain molecular hydrogen and how it interacts with the body’s systems, as well as review its benefits and the clinical research to support its effectiveness. We’ll also, of course, give you a final verdict for whether or not this supplement’s worth adding to your routine.

Itching to learn more? Let’s dive right into this H2 Restore review!


Polyphenols are micronutrients with antioxidant and anti-inflammatory properties that occur naturally in fruits, vegetables, teas, dark chocolate, red wine, and spices. There are more than 8,000 types of polyphenols, including resveratrol in red wine, catechins in fruits, and flavonoids, such as quercetin. Their antioxidant effect protects against oxidation, free radical-induced damage, and their anti-inflammatory benefits combat low-level chronic inflammation – a precursor to chronic diseases. Polyphenols are beneficial for heart health by managing blood pressure, helping prevent diabetes by controlling blood sugar and managing glucose tolerance, and may even help prevent cancer. 

Boosting the effectiveness of polyphenols certainly seems a worthy attribute of H2 Restore supplementation.

Molecular Hydrogen 

Doctor Gundry tells us H2 Restore is the perfect way to give your body “easy access” to molecular hydrogen most quickly and conveniently possible. For those unfamiliar with hydrogen, it is a flammable, colorless, odorless gas that acts as a reducing agent under certain circumstances. In addition, H2 acts as a very potent antioxidant protecting the body from oxidative damage. Since these antioxidant properties were discovered in 2007, multiple research studies have shown beneficial health effects in animals and humans. In reviewing these clinical studies, the NCBI, National Center for Biotechnology Information concludes there should be additional research in using hydrogen medicine in human disease prevention and therapy. “H2-based therapies show great promise as novel and innovative tools to prevent and treat human ailments that are currently major health burdens globally.” 

In addition to its antioxidant benefits, H2 functions as an anti-inflammatory, anti-apoptotic, and stimulates energy metabolism. It is rapidly diffused into tissues and cells and has little or no known adverse effects. Methods to deliver H2 include inhaling H2 gas (not practical outside of a lab or medical setting), drinking H2-dissolved water (H2-water) (less problematic; however, H2 evaporates over time and may be lost in the gastrointestinal tract), injecting H2-dissolved saline (H2-saline), taking an H2 bath, or dropping H2-saline into the eyes.

So, how does H2 Restore promote the formation of hydrogen in the body? The magnesium compounds in H2 Restore act as reductant agents for oxidizing water into hydrogen. Placing the magnesium tablets into water produces hydrogen-rich water. The magnesium powders create a mild chemical reaction between the magnesium and water, leading to the generation of hydrogen bubbles. This simple yet effective process produces a hydrogen antioxidant solution. 

What is H2 Restore from Gundry MD?

H2 Restore is a dietary supplement from Dr. Steven Gundry and Gundry MD. It comes in quick-dissolve tablet form featuring only magnesium and a trademarked, proprietary blend H2MgReact, with magnesium as its primary component. The company promises that the product will enhance the benefits of the polyphenols you consume while supporting your muscles and joints and boosting energy and metabolism.

Like most Gundry products, H2 Restore follows a go-to-market strategy that features many of the tactics employed by the best-in-class manufacturers in the dietary supplement space. The products are doctor-formulated, frequently using patented or trademarked ingredients. Manufacturing is in a cGMP-certified facility in the U.S., and finished goods are quality and purity tested by an independent third-party laboratory.

Although most Gundry products are non-GMO and Vegan friendly, there is no mention of this on the H2 Restore product page.

H2 Restore Ingredients

H2 Restore contains only two ingredients, Magnesium, 80 mg, and a proprietary blend, the trademarked H2MgReact, 400 mg. By weight, the H2MgReact compound is greater, so we review its components first.

gundry md h2 restore supplement facts

H2MgReact, 400 mg

The proprietary blend consists of Non-Ionic Elemental Magnesium, DL-Malic Acid, and Tartaric Acid. We cannot determine the precise amount of each compound due to being a proprietary blend. We know that Non-Ionic Elemental Magnesium is the most prevalent of the three by weight.

Non-Ionic Elemental Magnesium

Magnesium, the fourth most abundant mineral in the body, is responsible for more than 300 enzymatic reactions and is crucial for bone health. It is essential for the proper function of muscle contraction, nerve transmission, and neuromuscular conduction and is required to synthesize DNA, RNA, and the antioxidant glutathione. Due to its many bodily processes, it is thought to play a significant role in disease prevention and treatment. Note: The amount of “elemental magnesium” is how much magnesium the supplement actually contains.

DL-Malic Acid

The DL in this Malic Acid tells us the compound is produced in the laboratory versus that found in nature – such as in apples, berries, cherries, peaches, etc. – malic is derived from the Latin “malum” or apple. The DL also creates a conflict with the Gundry website’s statement, “Gundry MD H2 Restore contains only natural and pure ingredients.” Malic Acid is commonly used in skin and hair care products as well as supplements. It plays an essential role in generating energy from the foods we consume. 

Tartaric Acid

This organic acid occurs naturally in citrus fruits, grapes, and bananas. Tartaric is one of the Alpha-hydroxy acids (AHAs), plant and animal-derived acids frequently used in skincare products and as a food ingredient. It provides immunity support due to its antioxidant properties, is used as a digestive aid, and improves glucose intolerance.

Magnesium 80 mg

The Supplement Facts label simply lists Magnesium without specifying the type or source. Magnesium’s RDA (Recommended Daily Allowance) for a healthy adult is 320 – 420 mg. The two sources of Magnesium in H2 Restore should meet or exceed this requirement.

H2 Restore Benefits

Doctor Gundry positions H2 Restore as “the perfect way to give your body access to molecular hydrogen in the quickest and most convenient way possible.” Given the NCBI’s endorsement of the potential for positive health outcomes from molecular hydrogen, this represents a significant benefit of H2 Restore. A simple tablet mixed with water is a far easier, more convenient H2 delivery method than inhalation of the gas, injections, even bulky, expensive bottled hydrogen water alternatives.

H2 Restore, with its more sophisticated formulation than the competition, delivers highly bioavailable magnesium to promote molecular hydrogen. Benefits include potent antioxidant properties, increased energy, an anti-inflammatory effect, all in addition to enhancing the benefits of your polyphenol consumption. 

Further benefits include healthier cells, muscles, brain, kidneys, and heart, leading to anti-aging. Elite athletes benefit from H2 supplementation as it enhances endurance and recovery from oxidative stress due to vigorous exercise.

As to the previously mentioned anti-apoptotic effect – H2 inhibits apoptosis, programmed cell death and may reduce the effects of cancer radiotherapy or anti-tumor drugs.

One tablet mixed in a glass of water – may be used up to four times per day. The site recommends letting the tablet dissolve for about sixty seconds and then consuming it within twenty minutes. Remember, hydrogen evaporates. Typical use is for an energy boost in the morning, as needed for added energy throughout the day, or recovery from intense exercise. 

How Does H2 Restore Perform?

Improved energy is the most noticeable effect of H2. With its superior formulation and delivery mode, we believe H2 will produce many of the additional benefits described above including, its free-racial damage protection, enhanced endurance, and recovery from strenuous exercise. There is a reason trainers and nutritionists recommend this product for elite athletes. Plus, increased water consumption and staying hydrated is always a sound strategy.

Is H2 Restore Safe?

There are no reported adverse effects from H2 Restore, and experts don’t believe there are any health risks. H2 should be considered safe for all healthy adults; however, whenever you consider adding a new supplement to your regimen, particularly if you have a pre-existing condition or are on prescription medicines, you should consult with your healthcare provider.

In Summary: H2 Restore Review

We began this review with a healthy dose of skepticism regarding H2 supplements, their viability, and efficacy. However, the science, the comprehensive formula, and the logic of the delivery system swayed our opinion. Most competitive products in the H2 supplement space have one primary ingredient, Magnesium, at an 80-mg dosage with Malic and Tartaric Acids listed below the Supplement Facts panel as Other Ingredients. H2 Restore has the exact 80-mg dosage, plus an additional 400-mg of Elemental Magnesium, Malic Acis, and Tartaric Acid at very comparable prices.

Whether you’re an elite athlete, weekend warrior, or just looking for added energy with significant other benefits, we feel H2 Restore may be an excellent addition to your exercise regimen.
