The Active Ingredient Is: Vitamin B12 (Methylcobalamin)

Vitamin B12, in its methylcobalamin form, is a water-soluble vitamin that plays a key role in normal nerve function and energy metabolism. It is the biologically active form used by the body in essential metabolic processes.

This form is readily utilised in the body, supporting the maintenance of normal red blood cell formation and overall vitality as part of standard nutrient function in healthy individuals.

What Does Vitamin B12 Do?

Vitamin B12 participates in energy metabolism and helps maintain nerve function, with a role in supporting normal neurological processes and blood cell formation. It plays a part in the conversion of methylmalonyl-CoA to succinyl-CoA and in methionine synthesis, contributing to normal metabolic activity.

By supporting these pathways, B12 helps sustain everyday energy and nervous system function in line with recognised nutrient function claims.
