Creatine? I took it for a long time when i was still weight lifting, while struggling with depression at the same time. For me the creatine did not have any effect on my depression, unfortunately. But maybe it depends on dosage or something like that. It would be great.
Personally i have high hopes, that some of those Nootropics ( https://newmind.com/nootropics.html
) will be big in curing depression in the future. The first few studies actually existing sound really promising.
