Tag: Biotin metabolism

While most people do not experience adverse effects from biotin supplementation, even at high doses, individuals with pre-existing kidney or liver conditions should exercise caution and consult with their healthcare provider before starting any new supplement. As a water-soluble vitamin, excess biotin is typically excreted through urine, minimizing the risk of toxicity in healthy individuals. However, its interaction with laboratory tests is a significant consideration for anyone taking it.

As a water-soluble vitamin, excess biotin is not stored in the body and is instead excreted primarily through the kidneys. In healthy adults taking standard doses, biotin has a circulating half-life of approximately two hours, but the answer to the question, "How fast does biotin leave the body?", is more complex for those taking high-dose supplements.
