They are reporting information about hydrogen water safety and usage.
Molecular hydrogen is very safe. It has been scientifically studied for over 12 years, with nearly 1,000 studies and articles showing it is safe. Hydrogen gas is naturally produced in the gut, producing liters of hydrogen after a fiber-rich meal.
Molecular hydrogen, scientifically studied for over 12 years with nearly 1,000 studies and articles attesting to its safety, is increasingly recognized for its potential health benefits. Naturally produced in the gut after a fiber-rich meal, hydrogen gas appears safe to consume in regulated amounts. However, its safety doesn’t automatically translate into unlimited consumption.
Maximal Hydrogen to Consume: No definitive ‘maximal level’ of hydrogen is set for consumption. However, most studies typically use a concentration of 1.6% hydrogen in the air, below the flammability level. Regarding hydrogen-rich water, concentrations generally range from 0.5 to 1.6 millimolar (mM). Studies have tested higher dosages, but it’s generally recommended to follow the manufacturer’s instructions for hydrogen-rich water products.
Difference Between Hydrogen Water Drinking and Pure Hydrogen Inhalation: Drinking hydrogen water and inhaling hydrogen gas can both deliver molecular hydrogen into the body. Inhaling hydrogen gas allows for a higher concentration and faster delivery, but it requires specific equipment and safety measures due to hydrogen’s flammability. Hydrogen-rich water, on the other hand, is safe, easy to consume, and offers a more controlled delivery method.
FDA Verdict on Hydrogen as a Health Supplement: As of my knowledge cutoff in September 2021, the U.S. Food and Drug Administration (FDA) does not regulate molecular hydrogen as a drug. Instead, products like hydrogen-infused water are typically marketed as dietary supplements. The FDA does not approve dietary supplements in the same way it does drugs, but it does require that they are safe for consumption.
Maximal Dosage of Molecular Hydrogen Ever Tested on Humans: In terms of inhalation, humans have been exposed to concentrations as high as 4.1% hydrogen gas for 30 minutes with no adverse effects observed. While there is no established upper limit for hydrogen water, most studies have used concentrations of up to 1.6 mM.
Recommended Amount of Hydrogen Water to Consume: The exact amount varies, but consuming around 1–2 liters of hydrogen-rich water daily is generally suggested.
Benefits of Pure Hydrogen Inhalation Compared to Drinking Hydrogen Water: Inhaling hydrogen gas can deliver a higher concentration of hydrogen to the body and provide quicker effects. This might benefit acute conditions or use in a medical setting. Hydrogen water, though delivering lower concentrations, is easier and safer for everyday use, and it also hydrates the body.
FDA Approval of Hydrogen as a Health Supplement: As of my last update in September 2021, the FDA has yet to approve molecular hydrogen as a health supplement specifically. However, hydrogen-infused water and other hydrogen-rich products can be marketed and sold as dietary supplements.
While molecular hydrogen appears safe and potentially beneficial, individuals should consult a healthcare professional before beginning any new health supplement regimen. Potential risks or side effects are minimal but could include mild gastrointestinal issues, particularly when starting consumption. More research is needed to understand the long-term effects of hydrogen consumption fully.
