Vitamins are essential micronutrients required for the normal functioning of the body. Among them, vitamin A plays a particularly important role in supporting vision as well as immune defense. This vitamin belongs to the group of fat-soluble vitamins and has the ability to accumulate in the body. Therefore, its intake should be carefully balanced.
