How to read this ranking
This page compares Vitamin A (Vitamin A, RAE), in µg per 100 g of food.
Chemical forms and measurement methods remain separate. “Not reported” means a value is unavailable, not that the food contains zero. A food’s rank does not determine your individual needs or diagnose a deficiency.
This NIH fact sheet discusses the nutrient family. Vitamin A, RAE is the specific USDA measurement on this page. Do not apply family intake recommendations directly to this form or unit; use the definitions, population groups, and food/supplement distinctions in the source.

What are vitamin A and carotenoids and what do they do?
Vitamin A is a fat-soluble vitamin that is naturally present in many foods. Vitamin A is important for normal vision, the immune system, reproduction, and growth and development. Vitamin A also helps your heart, lungs, and other organs work properly. Carotenoids are pigments that give yellow, orange, and red fruits and vegetables their color. Your body is able to convert some carotenoids into vitamin A.
There are two different sources for vitamin A:
- Preformed vitamin A is found in fish, organ meats (such as liver), dairy products, and eggs.
- Provitamin A carotenoids are turned into vitamin A by your body. They are found in fruits, vegetables, and other plant-based products. The most common provitamin A carotenoid in foods and dietary supplements is beta-carotene.
