HYEST Vitamins deliver molecular hydrogen, which has been shown in clinical studies to support antioxidant and anti-inflammatory responses. Most users notice subtle improvements in energy and recovery within a week when taken as directed.
HYEST Vitamins are meticulously designed for each formulation. The highest quality ingredients are used to complement each component of these formulations. When taken as directed, the capsules are swallowed, and the chemical reaction in the stomach release molecular hydrogen into the bloodstream and then to every part of the body. Since hydrogen is the smallest molecule in the universe, it gets into the smallest areas of the body to work at the cellular level AND crosses the blood brain barrier for inflammation reduction in the brain.
Yes. Molecular hydrogen (H₂) is generally recognized as safe (GRAS) and has no known toxicity at therapeutic doses. Our product is manufactured under strict quality standards, and side effects are extremely rare when used as directed.
Studies published in Nature Medicine Medical Gas Research, Biochemical and Biophysical REsearch, and Scientific Reports has demonstrated that molecular is on the cutting edge of free radical reduction and elimination in a multitude of disease states. Feel free to Google or use ChatGPT to uncover the hundreds of published articles.
We stand behind our product with a satisfaction guarantee. If you don’t notice any benefit within 30 days, simply contact our customer support team to initiate a full refund according to our return policy.
Our proprietary hydrogen blend reduces inflammatory biomarkers and is patented for easing cold and flu symptoms, with more patents pending. While many clients notice benefits within a week, others may need 60–90 days for subtler effects. Individual responses vary, but HYEST Vitamins’ hydrogen provides antioxidant benefits from day one.
Backed by extensive research and delivered in a convenient format, HYEST offers cost-effectiveness compared to other supplements. Its pricing is competitive among hydrogen-based products. Thanks to complementary ingredients in each formulation, HYEST can replace multiple daily supplements, acting as a multi-vitamin with molecular hydrogen. Considering the complementary ingredients in each formulation, you will most likely be able to reduce your daily supplement regimen by using HYEST as a “multi-vitamin with molecular hydrogen.”
You can benefit from molecular hydrogen by inhalation from hydrogen gas inhaler (VERY expensive), using electrolysis devices (dosing is not consistent or as concentrated), dissolve tablets in water (dosing not consistent and tastes terrible), taking hydrogen baths (impractical and expensive), or taking HYEST Vitamins.
“Hydrogen” refers to the elemental form (atomic hydrogen, H), which is highly reactive. “Molecular hydrogen” (H₂) is a stable diatomic gas—that’s the form used therapeutically because it can diffuse easily through tissues and selectively neutralize harmful free radicals.
Hydrogen is the lightest chemical element, consisting of one proton and one electron. As a gas (H₂), it can act as a selective antioxidant in the body by neutralizing the most harmful reactive oxygen species without disrupting essential cell signaling.
