The number of supplements for nail health is continuously increasing, and consumers are no longer familial with them, which can create confusion, as they do not always understand what they are consuming, and some will seek advice from their dermatologist, who must have as clear and a precise answer.
Biotin, collagen peptides, solubilized keratin MSM, and choline-stabilized orthosilicic acid have been shown to improve the clinical appearance of nails, strength, and brittleness. There is a lack of regulation from the health authorities concerning dietary supplements. Manufacturers are not required to carry out efficacy and safety studies before marketing.
Dermatologists must be aware of the ingredients available on the market, their possible benefits but also their risks. It is important to specify to patients that our recommendations are as solid as the available evidence. In this article, we will discuss about the supplements available for nails, their mechanisms of action, and possible side effects.
