What the evidence says
NIH ODS confirms thiamine is essential and that supplementation reliably corrects deficiency (beriberi, Wernicke-Korsakoff syndrome), which occurs mainly in specific populations with poor intake or absorption. Evidence for benefits beyond correcting deficiency, in people with adequate intake, is limited.
Dose studied
1.1–1.2 mg — adult RDA, per NIH ODS.
Context
NIH ODS lists an RDA of about 1.2 mg/day for adult men and 1.1 mg/day for adult women; no tolerable upper intake level has been set because excess is generally excreted.
