Okay, so now I have an idea of what they are, but I am still curious as to how a person can get this stuff into their system.I have thought of gingko biloba pills and drinking green tea, but I'm sure you may have other suggestions.I am particularly intrigued by your mention of macular degeneration as I have two young nieces who have been diagnosed with macular degenerative disease. Each girl is the daughter of a different sister of mine, and it is very rare for people to get this disease unless they are very old. This suggests a genetic component to macular degenerative disease which apparently does not exist, according to "the literature".Perhaps the lack of ability to get enough flavinoids naturally is a genetic thing? Or do the flavinoids help with some underlying inherited condition?I have also discovered that there are links between sensitivity to MSG and macular degenerative disease, and I have IBS D with GERD and extreme sensitivity to MSG. Interesting to think about possible genetic inheritance of sensivity to MSG, or something that reacts to not getting enough flavinoids! I wonder if there is a link between this?Comments are welcome, and I would like to hear about how to try the "flavinoid approach" !Thanks . . . from Lexi.
