Vitamin A; it is a soluble vitamin in fatty bodies, which can not be released in the urine as other vitamins normally do, it is said that we consume large quantities in an inactive form since this is necessary for many human body processes such as vision, formation and maintenance of skin cells, the immune system, growth and even lactation and embryonic development, therefore it is not necessary to be active to consume large amounts of this vitamin.
