Carotenoid dynamics in humans 1015 The metabolism of other provitamin A carotenoids has been much less studied; presumably, they are converted into vitamin A, either by central or asymmetric cleavage. CONCLUSIONS: Humans appear to absorb various carotenoids in a relatively non-specific fashion, but absorption kinetics and plasma transport seem to differ among carotenoids, possibly because of differences in polarity. Despite the evidence for the health benefits of carotenoids, large population-based supplementation studies have produced mixed results for some of the carotenoids.
