The formulas for Viviscal's hair growth supplements for men and women vary slightly. Both contain a proprietary blend of shark and mollusc powders called AminoMar Marine Complex. Both formulas also contain vitamin C, zinc and horsetail extract, though the amounts of each ingredient in the two formulas vary. The men's formula includes flax seed extract, and the women's formula contains niacin, biotin, iron and millet seed extract.
Other, non-active ingredients that are present in both formulas of Viviscal include cellulose, maltodextrin, silicon dioxide, magnesium stearate and artificial orange flavoring. Biotin, an ingredient in the women's Extra Strength formula, is a water-soluble B vitamin complex, also known as vitamin H, that aids the body's ability to metabolize amino acids, carbohydrates and fats.
Viviscal Hair Growth and Hair Care Programs claim to promote the growth of existing hair while nourishing thinning hair in both men and women through the use of supplements, topical serums, shampoos and conditioners and hair filler fibers. The Viviscal Man supplements are designed to target the possible nutritional causes of male-pattern baldness. The ingredients in the Extra Strength formula for women have a special focus on preventing iron-deficiency anemia, a potential cause of thinning hair in women. The company notes that these claims have not, as of 2015, been evaluated by the Food and Drug Administration.
