<h4 class="dechead">On One Hand: Recommended Daily Allowance
According to the National Library of Medicine, Vitamin A is found in foods like eggs, liver, fruit and dark vegetables. Eating five servings of vegetables and fruit each day will give an adult 50 to 65 percent of the daily recommended portion of Vitamin A.
On the Other: Excessive Use of Supplements
According to the Mayo Clinic, excessive amounts of this vitamin are not flushed out. They are stored in the body and can be toxic at high levels. Some signs that a person is getting too much Vitamin A are a dry mouth, gums that bleed, or lips that crack.
Bottom Line
Most people do not eat a diet rich in fruits and vegetables. For this reason, unless a person takes an unusually high dosage of Vitamin A, there is no risk of toxicity. Eating a well-balanced diet and taking a daily multivitamin should not result in an excess of Vitamin A.
