Vitamin A, the base for all retinoids, is an essential nutrient found in many common foods like liver and dairy. However, the question of "can retinoids be ingested" in the form of skincare products or high-dose supplements is complex and carries significant health implications. The method of intake dramatically alters the body's processing and potential risks.

The National Institutes of Health states that the tolerable upper intake level for preformed vitamin A is 3,000 mcg RAE daily for adults. Understanding if it's safe to take vitamin A for a long time is crucial because exceeding this limit may lead to serious health problems.

According to reputable medical sources, consuming excessive amounts of preformed vitamin A, often from high-dose supplements, can cause a serious condition known as hypervitaminosis A. Understanding the symptoms if you have too much vitamin A is crucial, as this toxicity can lead to severe health complications affecting the liver, bones, and nervous system.
