The Active Ingredient Is: Vitamin B12 (Adenosylcobalamin and Methylcobalamin)

Vitamin B12 comes in two active forms that help energy metabolism and brain health. This mix includes adenosylcobalamin and methylcobalamin, which together aid mitochondrial energy production and cognitive function.

This version of vitamin B12 is sourced in a vegetarian-friendly lozenge and highlights bioactive and readily utilised forms for everyday bodily functions.

What Does Vitamin B12 Do?

Vitamin B12 helps with energy production and healthy brain function, supporting normal thinking and metabolism as recognised by EFSA guidelines and NHS advice.

In dual-form supplements, methylcobalamin supports neurological health and homocysteine metabolism, while adenosylcobalamin participates in mitochondrial energy pathways, contributing to normal energy release and cellular function.
