Vitamin D-3, the essence of health.
Vitamin D-3, also known as "liquid sunshine" is essential to healthful living and a sunny disposition. The modern recommended daily allowance of Vitamin D-3 is a scant 400 iu (international units). This is scarcely more than death prevention. Your body is capable of generating 10,000 iu of Vitamin D-3 with a mere 40 minutes of exposure to the sun.
Most current studies agree that to achieve the optimum blood level of Vitamin D-3 you need to intake 5000 iu per day. Now that WalMart carries 5000 iu gel tabs, this is affordable and easily accomplished.
