The average daily need of an adult to retinol - 1 mg, children - from 400 to 800 micrograms. Note that vitamin A is produced in the capsules content at 33,000, 50,000 or 100,000 IU (International Units).

Interestingly, the simple consumption of capsulesthe right quantity is not enough for the body to eliminate the deficit in vitamin A. It should be exactly even know how to use retinol. Thus, the capsules need to drink 2 times a day - morning and evening, and, exactly 10 minutes after the end of the meal.

Zinc deficiency also disrupts the conversion of vitamin A in the active components. Moreover, there is an inverse relationship. That is, these substances are interrelated.

Mineral oils are capable of dissolvingoil-soluble components: Vitamin A then passes through the gut, but not absorbed its walls. Therefore, regular use of mineral oils leads to a deficiency of retinol in the body, even if the products that you consume enough of this substance. The output will be a temporary waiver of mineral oils.
