How It WorksVitamin A was the first vitamin to be discovered and is essential in maintaining good vision and promoting normal growth. It occurs in animal tissues as retinol, but in plants as carotene—a vitamin A precursor. It is necessary for the health of epithelial cells and the immune system. It is also required for the digestion of protein. Extra amounts are stored in the liver, but megadoses over time can be toxic. It is essential for lactation, reproduction and the formation of steroid hormones. It is used to form the cells lining the digestive, respiratory, reproductive and urinary tracts and all tissue linings of the body. It is also vital for healthy skin. It is a fat soluble vitamin and best taken with food containing oil or fat. Individuals with low thyroid function may have a reduced ability to change beta carotene into vitamin A.
Vitamin D works synergistically with vitamin A. It has a role in absorbing and regulating calcium and phosphorous. It also helps build strong bones, teeth and skin. It is vital to the health of the nervous system and kidneys. It can be derived from the sun’s action on oils secreted and absorbed by the skin, but the more tanned the skin, the less absorbed. Also, the older the skin the less active its production of vitamin D. This vitamin helps the body synthesize protein and incorporate magnesium into bone and teeth structures.
