Vitamin B1, or thiamin, is a water-soluble nutrient that plays a big part in energy metabolism and nervous system function.

This form comes as thiamin in a B-50 complex and helps turn carbohydrates into energy through its job as a coenzyme in vital metabolic reactions.

What Does Vitamin B1 Do?

Vitamin B1 helps carbs metabolism and supports regular nerve function, helping keep energy going in the body.

Scientific research indicates that B vitamins act as coenzymes in energy metabolism, a finding aligned with EFSA and NHS guidance on nutrient functions. Dr. Williams of University of Cambridge found that B vitamins participate in key metabolic processes that support energy production.
