❓ Can biotin interfere with lab tests or medications?

Yes, biotin can significantly interfere with certain laboratory tests. A 2018 study showed that biotin supplementation can:

• Affect thyroid function test results
• Interfere with cardiac troponin testing
• Impact hormone level measurements

It's crucial to inform your healthcare provider about biotin supplementation before any blood tests. The FDA recommends stopping biotin supplements at least 72 hours before laboratory testing. Additionally, biotin may interact with certain medications, including some anticonvulsants and medications that affect liver function. Always discuss supplement use with your healthcare provider, especially if you're taking other medications.
