α-Carotene is a form of carotene with a β-ionone ring at one end and an α-ionone ring at the opposite end. It is the second most common form of carotene.

Human physiology

In American and Chinese adults, the mean concentration of serum α-carotene was 4.71 µg/dL. Including 4.22 µg/dL among men and 5.31 µg/dL among women.[1][2]

Dietary sources

The following vegetables are rich in alpha-carotene:[1]

  • Yellow-orange vegetables : Carrots (the main source for U.S. adults), Sweet potatoes, Pumpkin, Winter squash
  • Dark-green vegetables : Broccoli, Green beans, Green peas, Spinach, Turnip greens, Collards, Leaf lettuce, Avocado
