Vitamin D

Vitamin D
Vitamin D is a fat-soluble prohormone that we get from exposure to the sun or from foods and supplements. Vitamin D3 is the naturally occurring form of vitamin D. People need 15-30 minutes of sun exposure 2-4 times a week to keep adequate levels of vitamin D. Because most people have inadequate sun exposure throughout the year, many foods are fortifies with vitamin D. To prevent low vitamin D levels, the RDA for vitamin D for young people is 600IUs and for people over 70years old, 800-1000U. If labwork shows your vitamin D level to be low, it can be replaced readily with higher dosages. Vitamin D is important to bone health, brain functioning and neuromuscular health.
