Vitamin A is an essential nutrient for the body. This vitamin is fat-soluble and will have a great effect on maintaining healthy eyesight, immune system, and reproductive function. This vitamin also helps the heart, lungs, kidneys, and other organs to work at their desired level. There are two natural forms of vitamin A that we get from our food. The first vitaminA is found in meat, poultry, fish, and dairy products. The second type is called pro-vitaminA, which is found in fruits, vegetables, and other plant foods.
The recommended average amount of vitamin A for adults is 900 micrograms for men and 700 micrograms for women, and for some who have special conditions, extra vitaminA can be helpful. Acne, cancer, age-related macular degeneration, and vitamin A deficiency can all be treated with higher doses of vitamin A. However, what happens if you take too much vitaminA? We will answer this question below.

Even an overdose of vitaminA can cause health problems such as nausea, vomiting, dizziness, and blurred vision. Taking more than 10,000 micrograms of vitamin A day for a long time can cause worse conditions such as headache, bone thinning, liver damage, diarrhea, skin irritation, joint and bone pain, and birth defects in pregnant women. For this reason, when taking a vitaminA supplement, you should be careful about your doctor’s prescription or the instructions on the pill.
However, what about vitaminA products? You may have heard rumors that retinol can cause an overdose of vitaminA. Is this true? This is not true, according to Dr. Jeannette Graf, the clinical dermatologist at Mount Sinai Medical Center. Such rumors are “crazy,” he said, explaining that, “First of all, there has never been a case of hypervitaminosis A by someone who over-consumes vitaminA-containing skin products.” Retinol is the most natural form of vitamin A in the skin. There is a natural limit to the amount of retinol stored anywhere on the skin. “As a result, if you use it too much, it will certainly not be absorbed and there is no need to worry.”
So what is the result? Get enough vitamin A, but do not overdose on supplements and take them as prescribed by your doctor. Lastly, do not worry about using retinol.
