Improve Your Skin with These Foods
O, The Oprah Magazine | From the December 2008 issue of O, The Oprah Magazine
While experts agree that a well-rounded diet is the most dependable—not to mention all-around healthiest—route to better skin, there are a number of supplements with good science behind them.
Biotin: Studies have shown that 2.5 milligrams of daily biotin supplements can help strengthen brittle nails, says Noah Scheinfeld, MD, assistant clinical professor of dermatology at Columbia University. (Try Appearex, $32 for a 12-week supply.)
Heliocare: A Harvard study showed that these capsules, which contain a fern-derived antioxidant extract, help to prevent sunburn and collagen damage. Take two capsules one hour before prolonged sun exposure ($63 for 60 capsules).
Omega-3 fatty acids: If you don't think you're managing to get enough of these proven skin smoothers in your diet, consider fish oil capsules. Baumann recommends 1,000 milligrams of fish oil supplements (like Nordic Naturals Omega-3 Purified Fish Oil, $16 for 60 capsules) daily.
