I was having problems concentrating at work (I am an engineer.) I had to keep a list of what I was doing because I'd forget. I've done my usual "trial test," in which first I take the supplement, note differences, stop taking it, note differences, start again, note differences.
The Ginkgold has a clear benefit; when I'm taking it I can keep track of what I'm doing and do not need to keep a list. Highly beneficial. I am 60, and I take the Ginkgold Max.
But honestly not sure yet whether or not the patented EGb 761 contained in the Ginkgold tabs is any better than say the LEF variant which is cheaper by far per tab. I'll eat this bottle down and update this review if there's any dramatic difference between this brand and LEF: As it stands now I think they are equally efficient.
