Vitamin A, provided by Douglas Laboratories, contains 10,000 I.U. per softgel of Vitamin A palmitate in fish liver oil.
The most well - known function of vitamin A is its role in vision. As pa rt of the membrane - bound visual protein rhodopsin, vitamin A is essential in the eyes for converting light into nerve impulses. Night blindness and xeropthalmia are signs of moderate to severe vitamin A deficiency. Xerophthalmia is a common cause of preventable blindness in many underdeveloped countries around the world.
Vitamin A is essential for normal cellular differentiation. Its metabolite, retinoic acid, assumes a central role in gene activation and transcription. As a result, vitamin A status has profound effects on all rapidly dividing tissues in the body, such as immune cells and intestinal cells, and affects fertility, fetal development and growth.
Cellular differentiation is crucial for normal immune response, and vitamin A deficiency can start a vicious cycle affecting the immune system. During vitamin A deficiency, immune function is impaired, which puts the body at increased risk for infections. Acute infections further deplete the body of vitamin A, which leads to an even more impaired immune function and an even lower resistance to infections.
