Biotin, or Vitamin B7, is a water-soluble vitamin that plays a crucial role in metabolism. While the body needs biotin, it's essential to understand appropriate intake levels. The National Academy of Medicine has established Adequate Intake (AI) levels, recommending 30 micrograms (mcg) daily for adults and pregnant women, and 35 mcg for breastfeeding women. Most healthy individuals easily meet these requirements through a balanced diet, which includes sources like eggs, nuts, seeds, and certain vegetables.

Biotin supplements are widely available, often in much higher doses, ranging from 2,500 mcg to 10,000 mcg or more. While biotin is generally considered safe and non-toxic, even at high doses, due to its water-soluble nature (excess is excreted), there's limited scientific evidence to support the benefit of these mega-doses for hair, skin, or nail health in individuals without a deficiency. More importantly, taking high doses of biotin can significantly interfere with the accuracy of various laboratory blood tests, including thyroid function, cardiac markers (like troponin), and hormone levels. This interference can lead to misdiagnosis and inappropriate treatment.

Therefore, it is critical to inform your healthcare provider about any biotin supplementation, especially before undergoing blood tests. They can advise on appropriate dosages and necessary precautions to ensure accurate medical results.
