Visit the Store Visit the Store Biotin-8 offers a high concentration of biotin, a B vitamin that promotes fingernail strength and supports skin, hair, and nerve health, as well as healthy blood sugar metabolism.* Biotin in a higher amount, like in Thorne's Biotin-8, promotes glucose metabolism by stimulating glucose-induced insulin secretion in pancreatic beta cells and by accelerating glucose metabolism in the liver.* Biotin's benefit for fingernail strength was demonstrated in a clinical trial, where 45 patients with brittle nails received oral supplementation of 2.5 mg biotin for 1.5-7 months. Ninety-one percent showed "definite improvement," exhibiting firmer, harder fingernails after an average of two months of supplementation.* Biotin supports healthy skin, hair, and nerve function.* Biotin can also enhance muscle insulin sensitivity by increasing the uptake of glucose by muscle cells.* Thorne has been trusted by health-care practitioners, U.S. National Teams, and families around the world for more than 30 years. Trusted Manufacturer are a testament to Thorne's mission to provide high-quality supplements that are tested for quality, safety, and efficacy. By some estimates we are made up of as many as 37 trillion cells. The vast majority of these cells are subject to the various exposures of our daily lifestyle choices – such as exercise (or lack thereof), exposure to pollution, consumption of fruits and vegetables, and consumption of fast food. All of these choices, along with our genetic make-up, determine how fast we will age and how well our metabolism will function. Thorne's specially formulated products promote healthy aging and support metabolism so healthy aging occurs from the inside out.* We develop better standards for higher quality ingredients. Thorne cares deeply about where our ingredients come from. We partner only with suppliers whose practices emphasize quality, science, and responsibility. Better ingredients means better potency, absorption, and digestibility - and ultimately better health. We manufacture our own products to ensure full supply chain transparency. For more than 30 years, we have invested in clean manufacturing practices. We refuse to use ingredients that can inhibit absorption. We perform our final production in the United States. Our Charleston, SC facility is third-party certified. We run four rounds of review for each of our products. We have invested in two state-of-the-art in-house laboratories that allow us to conduct four rounds of testing. We test our raw materials, in-process batches, finish products, and product stability for each product. We believe the environment should never be compromised for the sake of business gain. At Thorne, we believe that doing our part to protect the environment and its most valuable resources goes hand in hand with our product quality standards. From product technology to ingredients and shipping materials, we're limiting waste and making responsible choices for our planet.
