Tag: Vitamin b1 toxicity

Thiamine, or vitamin B1, is a water-soluble vitamin essential for converting food into energy and maintaining proper nerve function. Because it is water-soluble, the body excretes any excess, making an overdose highly unlikely from food sources. This article explores the question, "Can you take too much B1?", examining the potential side effects, safety considerations, and the far greater risks associated with deficiency.

Health authorities, including the Food and Nutrition Board, have not established a Tolerable Upper Intake Level (UL) for oral thiamin because there is no evidence of adverse effects from high dietary or supplemental intake. This makes the question of "how much thiamin is too much?" less about toxicity for most people and more about understanding the body's natural processes.
