There are tons of anti-aging supplements that promise to make you look younger. But do they actually work? Here are the facts: 

  • First: For younger looking skin, wear a broad-spectrum SPF 30 sunscreen, and take fern extract. New research from the University of Miami School of Medicine shows that fern extract contains antioxidants that significantly reduce sun-related damage to your DNA – which is a major cause of wrinkles and age spots. 

  • For stronger nails, try the B-vitamin biotin. Research shows that a daily dose increases nail thickness by 25-percent, making your nails less likely to split and tear. And if you’re a swimmer, biotin helps prevent the damage from salt and chlorine that can lead to broken nails.

  • You can also boost fingernail health with fish oil. Either eat several servings a week of omega-3-rich flaxseed, and walnuts or cold-water fish like mackerel, sardines, and wild salmon. Or take a daily supplement.

  • Finally, to keep your hair from thinning – get more Iron – as well as Vitamin C – which makes it easier for your body to absorb iron. 

The experts say that one major cause of thinning hair is anemia. But iron helps increase the number of red blood cells carrying oxygen through your body, which is crucial to the health of hair follicles. You can get a good dose of iron from foods like spinach and artichokes – and beef, clams and oysters.
