Swanson Biotin Gummies are the easy and delicious way to boost beauty from within! A member of the B-complex family of vitamins, biotin is a popular supplement for healthy hair, skin and nails. While we are still learning how biotin works in the body, researchers believe it helps to reinforce the structure of keratin, the basic protein that makes up your hair, skin and nails that is responsible for giving them strength and resilience. Biotin is also an essential nutrient involved in energy metabolism. More specifically, biotin is a cofactor to five different enzymes that metabolize fat, protein and carbohydrates. Biotin works with your body to produce energy by helping to break down the proteins and fatty acids in your diet. It also plays roles in cellular signaling and gene regulation. Each two-gummy serving of Swanson Biotin Gummies delivers a potent 5,000 mcg biotin as D-biotin, the naturally occurring, biologically active form of this important nutrient. Juicy blueberry-flavored gummies are vegan and gluten free with transparent labeling of all ingredients.
