Zeaxanthin is one of the most common carotenoid alcohols found in nature. It is important in the xanthophyllcycle. Synthesized in plants and some micro-organisms, it is the pigment thatgives paprika (made from bell peppers), corn, saffron, wolfberries, and manyother plants and microbes their characteristic color.
Thename (pronounced zee-uh-zan'-thin) is derived from Zea mays (common yellowmaize corn, in which zeaxanthin provides the primary yellow pigment), plusxanthos, the Greek word for "yellow" (see xanthophyll).
Xanthophyllssuch as zeaxanthin are found in highest quantity in the leaves of most greenplants, where they act to modulate light energy and perhaps serve as anon-photochemical quenching agent to deal with triplet Chlorophyll (an excitedform of chlorophyll), which is overproduced at very high light levels, duringphotosynthesis.
Zeaxanthin supplements are used totreat different disorders, mainly with affecting the eyes. There are noreported side effects from taking zeaxanthin supplements. However, there is adecreased absorption rate when taken with Orlistat, mineral oil, and Chitosan.
