Gundry MD Ultimate H2 is a fizzing hydrogen tablet you drop into a glass of water. Alongside a magnesium-based molecular hydrogen blend, it adds citicoline and B12, positioning it as much for mental clarity and energy as for hydration, though the citicoline dose is on the low side compared to standalone cognitive supplements.

Ultimate H2 is Gundry MD’s molecular hydrogen supplement, an effervescent tablet built around a magnesium-based H2MG React blend that releases hydrogen gas when dropped in water, plus small doses of citicoline and vitamin B12. Molecular hydrogen is studied mainly as an antioxidant and anti-inflammatory agent; Gundry MD adds the citicoline and B12 to round the formula out toward energy and mental clarity rather than hydration alone.
400 mg
A magnesium-based blend (with malic acid and tartaric acid) that reacts with water to release molecular hydrogen gas, delivering roughly 80 mg of magnesium per tablet along with the fizz.
75 mg
Included to support cellular energy and cognitive function, though at roughly a third of the ~250 mg dose typically used in citicoline research.
100 mcg
Supports red blood cell formation and energy metabolism, using a well-absorbed methylcobalamin form.
cGMP-certified
Formulated in a cGMP-certified facility and third-party tested; contains no sugar, caffeine, artificial flavors, or artificial sweeteners.

Fizzes for about two minutes with a mild, slightly tart taste from the malic and tartaric acid, then dissolves fully. No added sugar, caffeine, or artificial sweeteners.
Drop one tablet into 10 oz of water. It will fizz for about two minutes while the molecular hydrogen releases, then drink once the fizzing stops. Gundry MD’s label recommends 1–2 tablets daily.
Third-party testing: Manufactured in a cGMP-certified facility and third-party tested for purity, per Gundry MD.
