The Active Ingredient Is: Vitamin B12 (Methylcobalamin)

Vitamin B12, or cobalamin, is a water-soluble vitamin essential for everyday nerve function and red blood cell formation. This product uses the methylcobalamin active form, which is more readily absorbed by the body.

This form is supplied as the biologically active methylcobalamin vitamin, commonly used in vegan friendly supplements to support metabolic processes tied to energy production and nervous system function.

What Does Vitamin B12 (Methylcobalamin) Do?

Vitamin B12 is involved in everyday functioning of the nervous system and helps maintain red blood cell production in a healthy way, in line with NHS and EFSA guidance.

Dr. Johnson of University of Cambridge found that methylcobalamin is more readily absorbed, which helps support normal neurological and metabolic functions.
