I take doses of Greens+ from time to time. I like it. I tried Piracetam and others but didn't put the effort in to identify how they affected me.
Do your perceived effects of Greens+ match the (somewhat inconclusive) results of this study? http://www.ncbi.nlm.nih.gov/pubmed/15217524?dopt=Abstract... I'm interested in trying it and would appreciate any extra information.
I know you didn't ask but I like sharing :) I also love eggs, especially pasteurized egg whites, and place them in the same category. To me pasteurized egg whites are equally as powerful. I would liken it to caffeine with no negatives but I don't like the sensation all the time.
Veggies like broccoli and spinach to a much less immediate effect. I would place berries higher than veggies. I take fish oil. Mayo Clinic recommends it.
And of course exercise. I weight lift like you see in the olympics, albeit with much less weight. It's a very efficient weight lifting related exercise. There's also sprinting, akin to spinning but fuller body, and swimming.
So that's my core physical body and mind well being philosophy :)
