What Does Vitamin B1 Do?

Vitamin B1 contributes to energy production by helping convert carbohydrates into usable cellular energy and is involved in supporting nervous system function, neurotransmitter synthesis, and maintenance of healthy homocysteine levels as part of wider B-complex activity.

In everyday physiology, B vitamins participate in energy metabolism and support brain and nerve system function as recognised in EFSA-style guidance.
