American scientists have recently discovered that overdose of vitamin A by pregnant women may cause abnormalities in newborn babies.

According to Le Monde, this conclusion was obtained after a study of 22,000 pregnant women by the Boston University School of Medicine. They divided these pregnant women into two groups. One group received 5000 international units of vitamin A per day, and the second group consumed more than 10,000 international units. Results The proportion of deformities in the first group of newborns was 1.3%, while the proportion of the second group was 3.2%.

Medical scientists believe that there are factors that cause excessive intake of vitamin A in some infant malformations, such as hare lips, hydrocephalus, and severe heart defects. These malformations occur in one in every 57 newborns. Some vitamin supplements now contain more than 10,000 international units of vitamin A. The harm of overdose of vitamin A is that it can damage the baby in the early embryonic stage, and at this stage, the mother does not know that she is pregnant.

However, American medical scientists also said that β-carotene, which can be converted into vitamin A, can be taken in large amounts without any doubt, because β-carotene is converted into vitamin A according to the human body’s needs. Cause damage.
