The Active Ingredient Is: Vitamin B12 (Methylcobalamin)

Vitamin B12 in its methylcobalamin form is a water-soluble vitamin crucial for everyday cellular function, DNA synthesis and nerve health. This active form is commonly used to support effective bioavailability in supplements.

Source information indicates methylcobalamin is the active B12 form utilised in this product for perhaps improved uptake and metabolic involvement in the methylation cycle.

What Does Vitamin B12 Do?

Vitamin B12 supports energy metabolism, red blood cell formation and neurological function, as outlined in well-established nutritional guidance. Dr. Eussen of Erasmus University discovered that high-dose B12 could raise serum levels, which could support energy-related functions when needed.

Additionally, B12 helps with methylation and neurotransmitter production, contributing to overall nervous system health and normal metabolic function.
