Can biotin disrupt hormones? HealthDay News — Biotin, which is included in many hair, skin, and nail growth over-the-counter products, can affect multiple hormone levels, according to a case study published online May 10 in the Journal of the Endocrine Society.
Does biotin affect hormone tests? Most of the published research on biotin interference covers hormone tests, such as parathyroid hormone (PTH), thyroid stimulating hormone (TSH), T4 and T3 tests, as well as tests for troponin. However, because biotin is used in so many immunoassays, scientists say it could interfere with many others.
What problems can biotin cause? Biotin supplements can cause problems if you take too much. Side effects can include skin rashes, digestive upset, problems with insulin release, and kidney problems. As with any supplement, the safety of long-term or high-dose use isn’t known.
Can Biotin Affect Hormone Levels
Most commonly, biotin use can result in falsely high levels of T4 and T3 and falsely low levels of TSH, leading to either a wrong diagnosis of hyperthyroidism or that the thyroid hormone dose is too high.
