The Key Ingredient Is: Vitamin B12 (Methylcobalamin)

Vitamin B12, in the methylcobalamin form, is a water soluble vitamin essential for energy production, red blood cell formation, DNA synthesis and nerve function.

This sublingual, bioactive form is presented in vegetarian, non-GMO preparation designed for fast absorption from the mouth.

What Does Vitamin B12 Do?

Vitamin B12 plays a role in energy metabolism and supports healthy red blood cell formation and nerve function. It also contributes to the normal metabolism of homocysteine, which supports overall neural and cardiovascular health in line with EFSA guidance.
