Nature's Sunshine A & D 10,000/400 IU

[Vital Nutrition]. Vitamin A was the first vitamin to be discovered. It has been shown to be essential in maintaining good vision and promoting normal growth. It occurs in animal tissues as retinol but in plants as carotene a precursor of vitamin A. 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 in all tissue linings of the body. It is also vital for healthy skin and is a famous antioxidant. It is best absorbed by the body when taken with oil or fat. Individuals with low thyroid function may have a reduced ability to change beta-carotene into vitamin A. For them, vitamin A from animal sources may be better. Each capsule contains 10,000 IU of vitamin A derived from fish oils, 200 percent of the Daily Value. Vitamin D works synergistically with vitamin A, preferring a 7:1 ratio. It plays a role in absorbing and regulating calcium and phosphorus. 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 reabsorbed by the skin. But the more tanned the skin, the less it is absorbed. Also, the older the skin, the less active it is in producing vitamin D. This vitamin helps the body synthesize protein and incorporate magnesium into bone/teeth structures.
