Hair & Nails Supplements

Hair and nail supplements may contain biotin, collagen, zinc, selenium, iron, amino acids and combinations of vitamins and minerals. They are available as capsules, tablets, gummies, powders and liquid formulas for different dietary preferences. Compare the ingredients and quantities rather than assuming higher doses deliver faster or better cosmetic results. Biotin deficiency can be associated with hair loss and brittle nails, but there is limited scientific evidence that high-dose biotin improves hair or nails in people without a deficiency. Biotin can also interfere with certain laboratory tests and produce incorrect results, so users should tell healthcare professionals and laboratory staff about supplements they take.
