The Active Ingredient Is: Vitamin B6 (Pyridoxal 5'-phosphate)

Vitamin B6, in its active pyridoxal 5'-phosphate form, is a water-soluble micronutrient involved in a bunch of metabolic processes essential for normal body function.

This form is the biologically active metabolite of B6 and helps with amino acid metabolism and neurotransmitter synthesis, contributing to the body’s ability to utilise amino acids effectively.

What Does Vitamin B6 Do?

Vitamin B6 takes part in amino acid metabolism and neurotransmitter synthesis, enabling normal metabolic function as recognised by EFSA and NHS guidelines.

It helps with the utilisation of amino acids and supports energy-related metabolic pathways when paired with other nutrients in the diet.
