Palm oil is the world’s richest natural source of carotenes in terms of retinol equivalent. Retinol equivalent (RE) is a measurement of vitamin A values in vitamin A sources.

When comparing palm oil with other food containing carotenoids, palm oil contains approximately 15, 44, and 300 times higher retinol equivalent than carrots, leafy vegetables and tomatoes respectively as shown in the table below.
