Vitamin B‑1, also known as thiamin, is a water‑soluble B‑vitamin naturally found in cereal grains, beans, nuts, eggs, and meats. It plays a vital role in energy production, supports healthy nerve tissue, and contributes to proper nervous system and muscle function. Thiamin is involved in the flow of electrolytes in and out of nerve and muscle cells, carbohydrate metabolism, and the production of hydrochloric acid necessary for proper digestion.
