Thiamin is a water-soluble B vitamin the body uses to convert food into usable energy and to support nerve function. It cannot be stored in meaningful amounts, so it needs regular dietary intake.
Why it’s used
Taken to meet daily requirements for thiamin, particularly by people whose diet or health situation puts them at risk of low intake.
What the evidence is for
correcting thiamin deficiency and preventing beriberi.
What the evidence says
NIH ODS describes thiamin as essential, with severe deficiency causing beriberi and Wernicke-Korsakoff syndrome; correcting deficiency reliably resolves these conditions. Evidence for benefits of thiamin supplementation in people who are not deficient is limited.
Dose studied
1.1–1.2 mg — adult RDA, per NIH ODS.
Context
Adult intake recommendations are set around 1.1 to 1.2 mg per day. No tolerable upper intake level has been set because high oral doses have not shown adverse effects in available data.
