5,000 mcg Biotin Complete B-complex MSM

Healthy Hair, Skin & Nails is a comprehensive blend of nutrients specifically formulated to enhance the appearance and growth of our hair, skin and nails. These tissues comprise the integumentary system, which is both the largest system in the body and also the only one that never stops growing. As a result, these tissues possess exceptional nutrient requirements, not available from even the healthiest diets. Although the appearance of these tissues does not directly affect our health, there is no denying its powerful impact on how we feel about ourselves.

The constant growth of our hair, skin and nails demands high levels of biotin - far higher than those found in any diet or typical multivitamin. We provide 5,000 mcg of our high bioavailability form of this remarkable beauty nutrient. We also provide high levels of MSM (methylsulfonylmethane), and exceptional source of sulfur - critical to the structure of our hair, skin and nails. We also include silicon and our sophisticated B-complex with our unique methyl B12 and methyl folate. The result is a comprehensive formula specifically designed to meet the diverse nutritional requirements of the most beautiful and healthy hair, skin and nails.

Contains no additives or common allergens Contains no milk, soy, yeast, wheat, gluten, sodium, salt, sugar, fat, cholesterol, color, preservative, common allergens, genetically modified (GMO) ingredients or manufacturing additives.
