In the quest of finding good nootropics, I've stumbled across
Rhodiola Rosea.
It seems like it's one of the best supplements for any kind of effort. It works on improving memory and concentration too if that's the case - it's an adaptogen(idk how that's spelled).
In the past I've taken Lecithin supplements, but they don't seem to have any effect. I've also taken Gingko Biloba, but didn't really felt anything with this either(well it's actually written in the prospect that you have to it continuously for at least 6 months to see any effect).
But 2 weeks ago I finished a batch of 500mg Spirulin capsules. I don't know what kind of improvements they had on my concentration and memory as I didn't study very hard at the time, but I obviously felt more energetic and could get away with less sleep while feeling rested.
I want to take 1000mg capsules of Spirulin and couple them with Rhodiola Rosea. While Spirulin is more affordable, Rhodiola seems a bit... expensive.
