Ginko biloba zero impact on memory???

I have often wondered at that myself. I began taking ginko biloba a while back when I thought my memory was slipping due to my age (64). I wanted to see if it worked. I don't believe it improved but I don't think it got any worse, either. At least, I stopped forgetting where I put my glasses. There have been various studies done on it to test the claim that it improves memory and the results have been conflicting, to say the least. No one can seem to agree. I contemplated not using it any more and a friend suggested that my memory might be worse than it is if I hadn't started taking it. So I'm still taking it every day.

I was a medical researcher is a former life, so here are a few comments on supplements in general. Most are sold based on tests in animals or in cells in a petri dish, not studies in real people. Unfortunately, you cannot extrapolate from tests in the lab to what happens in real people. Bodies are complicated and self-regulating and often the body responds in the opposite way to what the lab tests suggest. Companies selling these supplements want to make money so they take the tests that support the advantages of what they are selling and only tell you about those and they hype the tests up, but do not tell you exactly what the tests were. Almost all supplements are rubbish and make no difference. The only things they do is to make profits for the people selling them. The only effect they have is due to the placebo effect. You believe that they work and that belief gives you some benefit.
