Vitamin D


Vitamin D Benefits
Studies and research have shown vitamin D to have numerous benefits. It has been shown to help with healthier bones by helping calcium absorption and can lower blood pressure. It may also reduce risk of diabetes, rheumatoid arthritis, multiple sclerosis and lower chances of heart attacks.

Other Benefits
Some other benefits of vitamin D include the assistance with the proper functioning of your muscles, nerves and immune system. According to the CDC vitamin D also plays an important part in building strong bones in children and helps to prevent rickets and the softening of their bones.

Vitamin D Sources
Sunshine, certain foods and supplements are the main sources of Vitamin D. Getting sufficient vitamin D from the sun can be difficult because of limited exposure in winter, skin pigments and concern for over exposure. Trying to get vitamin D from food can be difficult because there are a limited number of foods which provide the recommended daily amounts of vitamin D without over eating. That is why supplements are commonly recommended. The RDA (Recommended Dietary Allowance) is 600 IU daily for adults ages 19 to 70 and 800 IU daily over age 70.
