Tag: Vitamin b1 overdose

According to the National Institutes of Health, there is no established Tolerable Upper Intake Level (UL) for oral thiamine (Vitamin B1) because no negative effects have been reported from high intake. This water-soluble vitamin is generally considered non-toxic, as the body excretes any excess through urine.

Unlike fat-soluble vitamins that can accumulate to toxic levels in the body, thiamine—or vitamin B1—is water-soluble, meaning excess amounts are naturally flushed out. This water-soluble property is the key factor in understanding what happens when your vitamin B1 is too high, especially from normal dietary intake.

Overdosing on vitamin B1, also known as thiamine, is extremely rare because it is a water-soluble vitamin that the body excretes when consumed in excess. While the body can tolerate high doses from food and most supplements, it's still important to understand the potential risks and rare side effects associated with excessive intake.

While excess vitamin B1 (thiamine) is typically excreted by the body, very high doses, particularly through synthetic supplements or injections, can cause adverse effects ranging from mild stomach upset to severe allergic reactions. Understanding the risks associated with excessive intake is crucial for safe supplementation.

According to the National Academy of Medicine, no established toxic level of thiamine (vitamin B1) has been reported in the literature. As a water-soluble vitamin, any excess thiamine consumed orally is typically excreted through the urine, making toxicity from food sources or supplements highly unlikely.
