Hair, Skin & Nails Supplements

Supplements commonly used as part of a hair, skin and nails routine. The largest family here is collagen: hydrolysed peptides, marine collagen and a multi-collagen blend, as powders, tablets and capsules. Alongside them sit biotin (vitamin B7) at 10 mg, silica with horsetail extract, horsetail on its own as capsules and as an alcohol-free liquid extract, and beauty multivitamins. The formats differ in practice. Collagen powder is dissolved into drinks and taken by the gram, while biotin, silica and horsetail come as capsules and tablets. Check each product's label for its source, strength and serving size. For the full collagen range by type and source, browse collagen supplements. Related: vitamins, minerals, and herbs.
