What foods or supplements maximize absorption (ie, blood levels) of zeaxanthin or lutein?
The reason I am asking this is that I read somewhere that corn has very high zeaxanthin levels, but the bioavailability is low for some reason. If this is so, one may have the same problem with orange peppers, etc, or even with certain nutritional supplements. Also with nutritional supplements it is very hard to know what is actually in them and how effectively the actual formulation is absorbed. Perhaps all that one needs to do is take some fatty food like cold water fish at the same time to increase absorption of a lipid soluble compound… I am also wondering whether antioxidants in the macula are very different from other antioxidants, given that they have to work effectively at unusually low PO2 levels. Answer: These are hard questions. It is clear that oral ingestion of lutein and zeaxanthin increase the serum level and increase the pigment levels in the macula in most but not all people. Recent evidence showed that supplementation with lutein increases the macular pigment more t
