HHS Carotenoids are a common and often ornamental feature in animals. COVID-19 is an emerging, rapidly evolving situation. The carotenoids that have been most studied in this regard are β‐carotene, lycopene, lutein, and zeaxanthin. [Potency of carotenoids found in vegetables and fruits]. There is evidence that carotenoids, in addition to beneficial effects on eye health, also produce improvements in cognitive function and cardiovascular health, and may help to prevent some types of cancer. The colorful carotenoid pigments are known as biological active compounds that have beneficial effects on the metabolism of animals and humans. Humans and other animals are mostly incapable of synthesizing carotenoids, and must obtain them through their diet. Particularly, the liquid-crystalline deposition of β-carotene and the storage of lycopene in very small crystalloids in papayas were found to be associated with their high bioavailability. This review is restricted to studies in humans, with a major emphasis on the most recent literature in the area of carotenoids and selected cancers. 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.
