Spirulina Is the Superfood Beauty Savior Your Regimen Has Been Missing

Spirulina is rich in vitamins, including A, C, E, and many of the B vitamins. It's also high in copper, calcium, iron, manganese, phosphorous, and zinc. This buffet of nutrients "gives the skin a beautiful glow," said Smith, especially when spirulina is consumed.

You can add spirulina to your diet by throwing in a tablespoon of powder in your smoothies or a glass of juice or water, or you can take it in pill form. Perricone MD's Super Greens Dietary Supplement ($80) contains spirulina and other green superfoods.
