    TLDR Some skin, hair, and nail supplements can be toxic, interact with medications, affect lab tests, and may increase cancer risk.
    The document "Risks of Skin, Hair, and Nail Supplements" from October 2020 discussed the potential dangers of using supplements for skin, hair, and nail health. These supplements, regulated as foods by the FDA, do not require proof of safety, efficacy, or quality before sale. The document highlighted risks such as acute and chronic toxicities, interactions with drugs and lab tests, and an increased risk of cancer with long-term use. High doses of vitamins A, B6, B12, E, and selenium, often found in these supplements, have been linked to higher cancer risk. Supplements like saw palmetto, used for hair loss, present a severe teratogenicity risk. Biotin, commonly used in hair and nail supplements, can interfere with certain lab tests, potentially leading to misdiagnosis. The document concluded by emphasizing the need for further research and regulation of the supplement industry.
