Magnesium

Roasted watermelon seeds provide a source of magnesium. Magnesium supports your metabolism so that your cells can produce the energy they need for day-to-day functioning. It also helps your body store energy by helping you make lipids, aids in cell migration and plays a role in cell communication. Each ounce of roasted watermelon seeds provides you with 146 milligrams of magnesium -- 35 percent of the RDA for men and 46 percent for women, according to the Linus Pauling Institute.
