What are sources of vitamin A?
1) Animal sources provide completely made (or preformed) vitamin A. Best sources include liver, fish oil, and eggs. 2) Plant sources contain carotenoids, which are modified to form vitamin A in your body. Carotenoids are found in red, yellow, orange, and many dark-green leafy vegetables. However, it takes twice the amount of carotene-rich foods to meet the body’s vitamin A needs. Thus, it is important to take a multi-vitamin that includes adequate amounts of vitamin A. Along with plenty of colorful fruits and vegetables, a multivitamin that contains at least 4000 IUs of vitamin A, such as that in the Life Time Fitness Performance Multivitamins, will provide insurance that vitamin A needs will be met.
