The Active Ingredient Is: Vitamin B12 (Methylcobalamin)

Vitamin B12 in the methylcobalamin form is a water-soluble vitamin essential for normal energy metabolism and nervous system function. This Bioactive B12 plays a key role in cellular processes and supports the body’s methylation cycle.

This formulation combines methylcobalamin with methylfolate and active B6 to optimise nutrient utilisation and supports methylation and neurotransmitter production through bioactive nutrient forms.

What Does Vitamin B12 Do?

Vitamin B12 is involved in energy metabolism and the recycling of homocysteine to methionine, a process linked to cardiovascular health in research contexts. The bioactive forms in this product, along with methylfolate and P5P, contribute to these metabolic pathways.

Dr. Lewerin of Uppsala University found that this combination increases plasma B12 and folate and lowers homocysteine, supporting cardiovascular and cognitive health aspects within the scope of normal physiology.
