Vitamin A is a fat-soluble vitamin and is stored in the liver. This is a very important vitamin for the development and perfection of fetal organs such as the heart, liver, lungs, kidneys, eyes, bones and central nervous system. For women preparing to become pregnant or are pregnant, vitamin A also helps the body recover after giving birth. However, supplementing vitamin A in addition to the daily diet also needs to be guided by doctors to avoid side effects when using an overdose. Below are the vitamin A requirements for pregnant and lactating women according to the World Health Organization: Pregnant women: average is 1,232 units (IU)/day; the recommended safe level is 2,664 units (IU)/day. Breastfeeding women: average requirement is 1,498 units/day; the recommended safe level is 2,830 units/day. Taking more than 10,000 IU of vitamin A per day can cause birth defects. However, you can use plant sources of beta-carotene because it takes many units of beta-carotene to synthesize one unit of vitamin A. The maximum amount of active vitamin A that you can consume in a day is 10,000 IU. Beta-carotene, also known as provitamin A, when entering the body will be converted into retinol when the body needs vitamin A. The level of conversion depends on the body’s vitamin A status. Therefore, the body does not have too much vitamin A but still meets the required amount when needed. Beta-carotene is generally considered safe because it is not associated with adverse health reactions and can be found in everyday foods. Therefore, experts advise pregnant women to use vitamin A in the form of beta-carotene found in foods such as yellow and red vegetables (carrots, tomatoes, pumpkins), animal liver (beef, chicken)… You need to check the total amount of vitamin A in each multivitamin pill and in a glass of milk to see if it exceeds the above allowable level and consult an obstetrician for advice on how to supplement vitamins appropriately and safely.
