If you're looking for hair, skin, and nail support, this high-dose **Biotin** gummy delivers 10,000mcg per serving — well above the 1,000–5,000mcg typical supplemental range. Biotin is widely marketed for hair, skin, and nail growth — but the clinical evidence for these benefits only applies if you're actually deficient, which is uncommon in healthy adults eating a varied diet.

The gummy format makes it easy to take, though it comes with 3g of sugar per serving from glucose syrup and added sugar. At two gummies daily with 30 servings per bottle, you're looking at a monthly supply.

The biggest thing to know before buying: there are no published RCTs showing biotin improves hair growth in people who aren't biotin-deficient. The mega-dose here won't cause harm — biotin is water-soluble and excess is excreted — but it can interfere with certain lab tests, including thyroid and troponin panels. Let your doctor know you're taking it if you have blood work coming up.
