The Active Ingredient Is: Vitamin B1 (Thiamine)

Vitamin B1, also known as thiamine, is a water-soluble vitamin essential for energy metabolism and normal nervous system function.

This form provides thiamine in a high-potency tablet preparation to support daily physiological needs and contribute to carbohydrate metabolism, with attention to general neural and muscular function.

What Does Vitamin B1 Do?

Vitamin B1 participates in energy production by helping convert carbohydrates into cellular energy and supports the synthesis of a key neurotransmitter involved in nerve and muscle activity.

It also contributes to normal nervous system and cardiovascular function as part of a balanced diet and lifestyle, reflecting its recognised role in energy utilisation and neural support.
