By - Nikita Parmar 2023-08-25 09:48:44 , 11 min readThe scientific name of vitamin A is retinol. It is also known as retinyl palmitate, retinal, and retinoic acid.
Too much vitamin A can be harmful, especially in pregnant women. Symptoms of vitamin A toxicity can include nausea, vomiting, headache, dizziness, and liver damage.
The recommended daily intake of vitamin A for adults is 900 micrograms (mcg) for men and 700 mcg for women. Pregnant women need 770 mcg of vitamin A per day, and breastfeeding women need 1,300 mcg.
It is possible to get too much vitamin A from eating too many carrots, but it is unlikely. The body can only store a limited amount of vitamin A, so any excess will be excreted in the urine. However, pregnant women should be careful not to eat too many carrots, as too much vitamin A can be harmful to the fetus.
The long-term effects of vitamin A deficiency can include night blindness, dry eyes, skin problems, increased risk of infections, growth retardation, and retinopathy. In severe cases, vitamin A deficiency can lead to blindness.
