The Active Ingredient Is: Vitamin B12 (Methylcobalamin)

Vitamin B12, in methylcobalamin form, is a water-soluble vitamin that’s essential for normal nervous system function and energy metabolism. This form is recognised for decent bioavailability and its role in metabolic processes.

Within a B-complex context this ingredient is complemented by other B vitamins to support metabolic function and cognitive health, with extra nutrients aiding in homocysteine metabolism and overall cellular energy production.

What Does Vitamin B12 Do?

Vitamin B12 helps keep normal nervous system function and supports energy production, which aligns with EFSA and NHS information on B vitamins in healthy metabolism.

Dr. Kennedy from Harvard University found that B vitamins in bioavailable forms contribute to energy metabolism and homocysteine regulation, underpinning nervous system maintenance and metabolic function.
