The Active Ingredient Is: Vitamin B1 (Thiamin)

Vitamin B1, also known as thiamin, is a water-soluble vitamin essential for energy metabolism and the normal functioning of the nervous system.

This product is a high-potency B-complex formulation presented in a plant-based capsule suitable for vegetarians and vegans, with thiamin alongside other B vitamins to support its roles in energy metabolism and nerve health.

What Does Vitamin B1 Do?

Vitamin B1 helps maintain normal energy-yielding metabolism and contributes to the normal function of the nervous system, in line with EFSA and NHS guidance.

Scientific insight from Dr Brown at University of Leeds suggests B vitamins help support metabolic pathways involved in energy production, highlighting their cooperative role in a B-complex blend.
