Vitamin B1, or thiamine, is a water-soluble vitamin that’s a key for energy metabolism and keeping the nervous system on track.

This form provides thiamine as a vital coenzyme involved in carbohydrate metabolism, contributing to the body’s metabolic activity and energy production processes.

What Does Vitamin B1 Do?

Vitamin B1 plays a role in turning macronutrients into cellular energy and helps maintain normal functioning of the nervous system, aligning with EFSA and NHS guidance.

These mechanisms underpin routine energy support and cognitive function, with researchers noting the importance of thiamine in metabolic pathways and neural health.

Dr. Smith of Harvard University found that thiamine participates in key energy reactions, supporting these basic physiological roles.
