What Does Biotin Do for Your Body?
Biotin, also known as vitamin B7 or vitamin H, is a water-soluble B vitamin that plays a key role in converting food into energy. It is essential for the metabolism of fats, carbohydrates, and proteins. While biotin deficiency is rare in healthy individuals, many people turn to supplementation to support the health of their hair, skin, and nails. Recent studies suggest that biotin can improve nail thickness and reduce breakage, especially in those with low levels. For hair, it helps strengthen the hair shaft and may improve texture over time. Combined with a balanced diet, biotin can be a valuable addition to your daily routine.

Choosing a High-Quality Biotin Supplement
When shopping for a biotin supplement, look for the active form (d-biotin) and a reputable brand like NOW Foods. Their Extra Strength Biotin is non-GMO, vegan, and kosher certified. It is manufactured in a GMP facility and lab-tested for purity – a sign of quality you can trust. The medium-sized vegetarian capsules are easy to swallow, making them ideal for daily use. Plus, the formula is free from common allergens: No wheat, gluten, soy, corn, milk, egg, fish, shellfish, tree nuts, or sesame. Avoiding unnecessary fillers ensures you get only what you need.
How Much Biotin Should You Take?
The recommended dietary allowance (RDA) for biotin is 30 mcg per day for adults – easily met through food. However, higher doses (such as 10,000 mcg) are often used for targeted hair and nail support. Because biotin is water-soluble, excess is excreted in urine, making high intakes generally safe. For most adults, one capsule daily with a meal is sufficient. That said, it's always a good idea to consult a healthcare professional before starting any high-dose supplement, especially if you are pregnant, nursing, or on medication.
Possible Side Effects and Considerations
Biotin is well-tolerated by most people. At high doses, some may experience mild digestive upset or skin reactions. A key consideration: biotin can interfere with certain lab tests, including thyroid function tests. Inform your healthcare provider if you take biotin supplements. Additionally, anticonvulsant medications may interact with biotin. Always speak to a doctor before combining supplements with prescription drugs. Risk information: keep out of reach of children. Do not use if seal is broken. Store in a cool, dry place.
