Biogena Vitamin B12 1000 Superior is built around the brand's MHA formula, combining all three naturally occurring, bioactive forms of vitamin B12 in one capsule: methylcobalamin, hydroxocobalamin, and adenosylcobalamin.

Rather than relying on a single synthetic form like cyanocobalamin, this triple-source approach mirrors how B12 actually exists and functions in the human body.

Methylcobalamin and adenosylcobalamin are the two coenzyme forms of B12 — meaning the body can put them to work directly in metabolic pathways without needing to convert them first.

Hydroxocobalamin, meanwhile, acts as the natural storage form, helping maintain stable B12 levels between doses.

Together, this balanced ratio is designed to support sustained bioavailability rather than a single short-lived spike.

Each capsule delivers 1000 µg of vitamin B12, contributing to normal energy-yielding metabolism and helping reduce tiredness and fatigue, supporting normal nervous system function and psychological wellbeing, aiding red blood cell formation, and contributing to normal homocysteine metabolism.

Because B12 occurs almost exclusively in animal foods, it's a particularly important nutrient for vegetarians and vegans to actively supplement.

The formula is manufactured according to Biogena's Pure Substance Principle — free from unnecessary colorants, preservatives, and technical additives — in capsules made from plant-based Vcaps® Plus shells, making the product itself suitable for vegans even though it addresses a nutrient gap most common in plant-based diets.
