α-Carotene (alpha-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.
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]
The following vegetables are rich in alpha-carotene: [1]
A 2018 meta-analysis found that both dietary and circulating α-carotene are associated with a lower risk of all-cause mortality. The highest circulating α-carotene category, compared to the lowest, correlated with a 32% reduction in the risk of all-cause mortality, while increased dietary α-carotene intake was linked to a 21% decrease in the risk of all-cause mortality.
