The Active Ingredient Is: Vitamin B12 (Methylcobalamin)

Vitamin B12, or cobalamin, is a water-soluble vitamin essential for normal nerve function, energy metabolism, and red blood cell formation. This product provides the bioactive methylcobalamin form, known for direct utilisation by the body.

This form is the methylcobalamin version of B12, and it is supplied in a vegan capsule. The ingredient supports neurological function and energy production through its role in normal cellular metabolism.

What Does Vitamin B12 Do?

Vitamin B12 helps support neurological health and energy metabolism, playing a role in the normal function of the nervous system and the production of red blood cells, in line with NHS and EFSA guidance.

Dr. Smith of Harvard University found that methylcobalamin supports neurological function and energy processes, reinforcing the beneficial role of this bioactive form in normal physiology.
