I don’t know if this is allowed. Delete if it’s not but like I have been looking into supplements to help with concentration. I know that Mudita wrote about taking L-Theanine when you drink a lot of coffee at work but I wondered if there were any other ideas. I saw that Holland & Barrett were selling ginkgo biloba and wondered if anyone tried it?
I have heard that ginko bilboa can work to aid memory but I’ve never tried it. I have used caffeine and l-theanine though, as well as creatine. However, I feel as though you might have more luck discussing nootropics on Reddit.
