Brighter, more vibrant, and more youthful from the inside out. \n \nLike other B-complex vitamins, biotin helps your body convert food into energy. But there's a reason it's also called "vitamin H" -biotin can helps support healthy hair and skin! Because biotin is water soluble, it cannot be stored in the body and must be acquired from your diet or through supplementation. \n \nSolaray Timed-Release Biotin is a high-potency supplement containing 5,000 mcg (16,667% DV) of biotin in each 1-VegCap serving. Our two-stage, timed-release formulas are designed to release half of the biotin rapidly and the other half gradually over a period of up to 8 hours, which may help provide sustained support over a longer period of time. With consistent use, Solaray Timed-Release Biotin may help support healthier skin, fuller, shinier hair, and longer, stronger nails. \n \nAlways committed to quality supplementation and better ingredients, Solaray Timed-Release Biotin is lab tested for purity and potency, so you know you're getting the very best to help you Live Brighter!
