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. ## Features - Hair, skin and nail health – Biotin, or vitamin B7, promotes keratin production. Keratin is a protein that is vitally important for healthy hair, skin and fingernails. - Promotes cellular energy production – Biotin also supports cellular energy and is used in a variety of metabolic processes. - Encourages healthy gene expression – The process of gene expression involves using a gene to create a protein.
