Biotin, 10,000 mcg, 100 Tablets

Natrol Biotin is a dietary supplement centered on biotin (vitamin B7) at a high supplemental dose. Biotin is a water-soluble B vitamin that functions as a cofactor for carboxylase enzymes involved in fatty-acid synthesis, amino-acid metabolism, and glucose-related metabolic pathways. True biotin deficiency can affect skin, hair, and neurological function, although deficiency is uncommon in the general population. The 10,000 mcg dose is far above the amount needed to meet normal daily nutritional requirements. High-dose biotin is widely marketed for hair, skin, and nails, but evidence for additional benefit in people without deficiency is limited. High intake is particularly relevant because biotin can interfere with some laboratory immunoassays. From a nutrition perspective, the value of this type of supplement is its ability to provide a measured, repeatable amount of the target nutrient or bioactive compound when food intake, lifestyle, or individual needs make consistent intake difficult. Evidence for nutritional support depends on baseline status, diet, dose, and individual factors; this product is intended to complement, not replace, a balanced diet.

Adults take 1 tablet daily with a meal.

Biotin can interfere with certain laboratory tests, including some cardiac and thyroid assays. Tell your healthcare professional and laboratory personnel that you are taking biotin before testing. Keep out of reach of children. Do not use if the safety seal is damaged or missing. If pregnant or nursing, taking medication, or managing a medical condition, consult a qualified healthcare professional before use. Store as directed on the label.
