TLDR Nutraceuticals may improve skin health and protect against aging, but more research is needed on their optimal use and possible health risks.
The review article from 2018 examines the effects of nutraceuticals on skin health and aging, highlighting their potential to counteract damage from factors like UV radiation and nutritional deficiencies. It discusses the benefits of amino acids, carotenoids, fatty acids, and minerals such as zinc, which is essential for skin cell function with an RDA of 11 mg for men and 8 mg for women. Polyphenols like curcumin and EGCG are noted for their anti-inflammatory and anticancer properties, while vitamins C and E are recognized for their roles in collagen synthesis and photoprotection. The review also identifies aloe sterol and Serenoa repens as promising nutraceuticals for skin elasticity and hair loss treatment, respectively. Although a balanced diet usually provides sufficient nutrients, supplementation may help those with deficiencies, but optimal daily allowances and health risks need further research. The review does not involve new studies but relies on existing literature, and it encourages healthcare providers to guide patients on the use of nutraceuticals and recommend certified sources for supplements.
