But some people lack Vitamin D, because many won't stay in the sun for long periods of time fearing they may develop skin cancer. According to the national institutes of health, one out of 3 Americans aren't getting enough of the supplement in their diet, which can lead to health problems. When Vitamin D levels get too low our bones weaken and the risk of heart disease, high blood pressure, dementia and certain types of cancer goes up.
So nutritionists recommend eating your Vitamin D. You can find it in oily fish, fortified milk, even egg yolks. Doctors recommend people from one years of age to 70 get 600 international units a day of vitamin d to get the full benefits.
