Selenium, particularly when chelated with amino acids, plays a crucial role as an antioxidant, safeguarding skin cells against oxidative stress and promoting the health of hair and nails. A study conducted by Piñero et al. (2021) on the effects of Selenium on lettuce grown under an aquaponics system provides insightful parallels into its antioxidant properties. Although the research primarily investigates Selenium's impact on plants, it highlights Selenium's potential to enhance antioxidant activity, which can be extrapolated to its benefits in human health, particularly in skin, hair, and nail health. The study found that Selenium application improved the antioxidant activity measured through ABTS, suggesting its protective role against oxidative damage. This antioxidant capacity of Selenium is vital for protecting skin cells from environmental stressors, thereby contributing to skin health. Furthermore, its role in supporting amino acid composition indicates potential benefits for hair and nail strength and vitality, given the importance of amino acids in protein synthesis, which is critical for hair and nail growth.
