Being your best starts with the B vitamins. And when it comes to glowing—inside and out—vitamin B7, more commonly known as biotin, plays a crucial role. Biotin supports the production of keratin, a protein that promotes luscious locks, supple skin and strong nails. Your body uses biotin for a variety of important metabolic processes, and this B vitamin may even play an important role in gene expression. While you can get biotin from your diet, the best way to know you’re getting enough is through supplementing. Our 600 mcg vitamin B7 formula is non-GMO, gluten-free and manufactured in the USA.
