Supplements that may help with skin and hair health include:
Vitamins
Vitamins A, B complex, C, D, and E, as well as biotin, can help maintain skin health. Biotin, also known as vitamin B7, can help with hair thinning. Vitamin C helps with collagen formation, which is important for skin function.
Collagen
Collagen can help with skin hydration and elasticity, and may also support hair growth. The body’s natural collagen production may decline with age, and people may not be eating enough collagen-rich foods like meat bones.
Omega-3 fats
These fats, which are often found in fish oil supplements, have anti-inflammatory properties that can benefit hair and skin health. You can also find omega-3s in nuts and seeds like almonds, chia, and flax.
Carotenoids
These compounds absorb UV light and free radicals, which can help protect skin from sun damage. However, consuming large amounts of carotenoids can turn your skin orange-ish.
You can also try eating a healthy diet high in plant foods like fruits and vegetables. These foods contain compounds that can help protect against cellular damage. You can also try avoiding cigarette smoke and excessive alcohol consumption.
