Dr. Mercola H2 Molecular Hydrogen, 90 Tablets (80 mg per Tablet)

Dr. Mercola H2 Molecular Hydrogen is a dietary supplement designed to support healthy aging, cellular energy, and a balanced response to oxidative stress by delivering molecular hydrogen through a dissolvable tablet. Each tablet contains 80 mg of elemental magnesium, which reacts with water to produce hydrogen gas, and the manufacturer states it can create up to 8 ppm concentration of H2 in 480 mL of water, a level they note is higher than many competing products that typically reach 1-2 ppm.

Developed by Dr. Mercola, this product uses a specialized, validated process to generate hydrogen-rich drinking water, intended for daily use as part of a wellness routine. The tablets are formulated to be gentle on the gut, indicated by a 'green' label in the manufacturer's Stoplight System for gut health, and are free from genetically modified ingredients and gluten. It is available in a 90-tablet bottle for a 90-day supply, with a travel-friendly variant called H2-2-Go™ offered in individually wrapped tablets.
