According to an article published in CNBC Make It, skin, hair, and nail supplements may contain levels of biotin that may be potentially harmful. The U.S. Food and Drug Administration recommends a daily dose of 0.03 mg of biotin for adults; however, some skin, hair, and nail supplements contain 650 times that amount. Experts explained that these high levels of biotin may affect thyroid and cardiac testing results, as well as vitamin D levels, and could potentially lead to false positives for conditions like hyperthyroidism. Further, experts warned that many popular brands of collagen supplements may contain toxic heavy metals like lead and mercury. They recommended that before taking any type of supplement, individuals should question if the product actually contains the ingredients listed on its label; if there is any evidence that supports the recommended amount as advised on the product; whether the manufacturer is a credible company; and if there has been any third-party testing of the product. Most importantly, the experts consulting a physician before taking any type of supplements, and advised that instead of taking supplements, establishing a well-rounded diet is the safest way to ingest “beauty” nutrients like biotin and collagen. Foods such as meats, bone broth, gelatin, beans, soy, fruits, leafy vegetables, and root vegetables contain nutrients that help to produce collagen.
