Hi.
I've done some testing with supplements in order to increase concentration and memory. Some supplements that I've tried has had a great effect. However, some of the others
is supposed to work according to research papers etc, but when I try them I don't really feel too increase in concentration and memory. This is the case for supplements such as Beta Caroten and CoQ10.
But they still might work. Even thought its not that much, they will still help a little bit.
So how can I can be sure that they're working for me? Is there a systematic way to test supplements avilable?
Thanks for input on this one
