Vitamin A (Retinol) Dietary Sources and Daily Requirements

Good Dietary Sources of Vitamin A (Retinol)

Because vitamin A can be found in both animals and vegetable sources, you can find vitamin A in many different foods. Vitamin A has numerous health benefits, so make sure you get enough in your diet each day. Consume a variety of the foods listed below, which are all healthy foods that contain high amounts of vitamin A.

Keep in mind that vitamin A can be easily be destroyed through excessive exposure to air and light. To keep the vitamin A content of foods intact, make sure you store fruits and vegetables inside sealed containers and keep them adequately refrigerated.

Depending on the acidity of the food, vitamin A can also break down when exposed to heat. Highly acidic foods are more likely to lose retinol when cooked, so try to eat these fruits and vegetables raw.

Meats

  • Liver is a very good source of vitamin A. Beef, pork, chicken, and turkey liver are all good choices. To keep the vitamin A content high, prepare the liver by braising it.
  • Other organ meats, such as kidney are also excellent sources.

Dairy

  • Low-fat and non-fat milk are often fortified with vitamin A and provide a good amount of the nutrient.
  • Yogurt, eggs, and cheese all contain vitamin A, as well.

Fruits

  • Orange and yellow fruits usually contain a good amount of vitamin A. This includes fruits like mango, cantaloupe, honeydew, apricots, and nectarines.
  • Plums and watermelons also provide small amounts.

Vegetables

  • Vegetables that are orange or red are among the best dietary sources of vitamin A. Carrots, red bell peppers, pumpkin, butternut squash, and sweet potatoes all contain large amounts of the vitamin.
  • Dark green and green leafy vegetables are also good foods to eat for vitamin A. Eat collard greens, kale, lettuce, spinach, or broccoli to boost your intake.

Fortified Foods

  • Many breakfast cereals are fortified with vitamin A, and some can contain a full day’s requirement in one or two servings.
