Top 10 Foods Highest in Alpha-Carotene

Like beta-carotene, alpha-Carotene is a precursor to creating vitamin A in the body.

Both alpha-carotene and beta-carotene are fat-soluble so they need to be consumed with fat to be absorbed efficiently in the digestive tract. (1)

The amount of active vitamin A in the body is measured in retinol activity equivalents (RAE). (2)

For every 24mcg of alpha-carotene you consume, the body creates 1mcg of RAE. (2) The daily value (%DV) for vitamin A is 900mcg of RAE. (3)

We calculate the daily intake target of alpha-carotene to be 24 times the daily value (DV) for vitamin A, which comes to 21600mcg (21.6mg) of alpha-carotene per day. If you were getting all of your vitamin A from alpha-carotene, then this is the amount that you would need.

In truth, it's not necessary to worry about meeting this target for alpha-carotene consumption. The goal is to get enough RAE in total, and other forms, such as beta-carotene, and vitamin A, also contribute to this total. The calculated RDA is simply a guide for comparing foods.

Foods high in alpha-carotene include orange vegetables like pumpkin, carrots, and winter squash. Other alpha-carotene food sources include tangerines, tomatoes, collards, napa cabbage, sweet potatoes, avocados, and bananas.
