The Active Ingredient Is: Folate (5-Methyltetrahydrofolate)

Folate is a water‑soluble B vitamin important for normal cellular processes and development.

This formulation uses 5‑methyltetrahydrofolate, a very bioavailable form of folate that can be easily utilised by your body.

What Does Folate Do?

Folate is involved in DNA synthesis and normal cell growth and supports normal psychological function, in line with EFSA guidance.

This nutrient may support mood stability through its role in metabolic processes linked to brain health, while supporting normal homocysteine metabolism. NHS and EFSA broadly recognise these functions as part of healthy physiology.
