Country Life High Potency Biotin 5 mg Gluten-Free Vegan Capsules For Hair, Scalp & Nails is the best biotin supplement to add to your daily beauty routine. Country Life's stand-alone biotin vitamin is the perfect solution. Biotin is a water-soluble B vitamin that supports the formation of keratin, which is a building block for hair, scalp, skin and nails. The body uses biotin to synthesize many amino acids, which later transform into keratin. Biotin also supports energy metabolism. Biotin is good not only for hair growth but also nail health as it helps stimulate keratin synthesis that helps reduce nail brittleness, strengthens them and helps maintain their shine. This biotin supplement is also certified vegan and gluten-free to suit your dietary needs. Wellness goals differ from person to person. That's why Country Life supplements focus on commonly deficient micronutrients that, when combined, can meet nearly any body's needs. Being healthy is essential to being happy and Country Life believe that good health is an important part of treating yourself well. With a 40 year plus heritage of providing wellness, Country Life's high quality products have been helping you stay happy and healthy since 1971.
