I’ve tried several light nootropics, superfoods, exercise, mediation, and more. The only thing that has really worked for me is a good diet, exercise, and a good lion’s mane mushroom supplement.

I stopped taking the supplement, because the benefit felt dwarfed by the other two, but I definitely felt like I had improved memory - and a couple others commented on this. I look forward to more studies on it to learn more.

Rhonda Patrick’s work is also particularly interesting. I haven’t gone that hardcore yet with diet but maybe it is worth an experiment.
