The Primary Ingredient Is: Vitamin B12 (Methylcobalamin)

Vitamin B12 in its methylcobalamin form is a water-soluble vitamin crucial for everyday energy metabolism and nervous-system function, and is suitable for vegan users.

This version is methylcobalamin, the active form of B12, and is often described as vegan-friendly and highly bioavailable.

What Does Vitamin B12 Do?

Vitamin B12 helps to support energy production and nervous system health, and contributes to red blood cell formation, in line with EFSA and NHS guidance.

Its role in keeping normal cognitive function and nerve health is noted in clinical contexts, with high-dose methylcobalamin used to support people with increased B12 needs or absorption challenges.
