What Is Vitamin A?

Vitamin A is a fat-soluble vitamin that plays an important role in vision, immune function, and the maintenance of healthy skin and mucous membranes. It also supports normal cell specialization and is essential for growth and development. Vitamin A exists in two main dietary forms: preformed vitamin A (retinol and retinyl esters) found in animal foods like liver, eggs and dairy, and provitamin A carotenoids (such as beta-carotene) found in colorful fruits and vegetables like carrots, sweet potatoes and spinach. In supplements, vitamin A may be provided as retinyl palmitate/acetate or as beta-carotene.

Benefits of Vitamin A Supplements

Vitamin A contributes to the maintenance of normal vision and the normal function of the immune system. It also contributes to the maintenance of normal skin and normal mucous membranes. Because vitamin A is involved in cell specialization, it supports many processes related to healthy growth. Vitamin A supplements are often used by people with low dietary intake, limited variety in food choices, or increased needs. However, because vitamin A is fat-soluble and stored in the body, it is important to avoid excessive intake, especially from retinol-based supplements.

Uses of Vitamin A

Vitamin A supplements are typically taken once daily according to the label instructions, often with food to support absorption. They are commonly found in multivitamins, immune-support formulas and skin-health supplements. Some people prefer beta-carotene forms, as the body converts beta-carotene into vitamin A as needed. It’s important to consider all sources of vitamin A, including fortified foods and other supplements, to avoid overconsumption.

Vitamin A: Side Effects and Safety

Vitamin A is safe in recommended amounts, but high intake of preformed vitamin A (retinol) can be harmful. Excess vitamin A may cause headache, nausea, dizziness, dry skin and, over time, more serious effects. High-dose retinol is not recommended during pregnancy because it can increase the risk of birth defects. People with liver disease or those taking certain medications (such as retinoids) should consult a healthcare professional before using vitamin A supplements. Always follow label directions and choose appropriate dosing.
