Is Thorne Biotin-8 Right for You?
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.* 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.*
Warnings: This product is contraindicated in an individual with a history of hypersensitivity to any of its ingredients. If pregnant, consult your health professional before using this product.
