In plant organisms, lutein, as an essential component of photosystems, fulfills the functions of light collection and photoprotection, among others.

It is localized on the inner … Lutein: Functions
Interactions of lutein with other agents (micronutrients, foods): Interactions between carotenoids Metabolic studies found that when high doses of beta-carotene were absorbed, they competed with lutein and lycopene when ingested within a meal. However, in long-term clinical studies, consumption of high doses of beta-carotene had no adverse effect on serum carotenoid levels. Dietary supplements versus … Lutein: Interactions
