Nootropics are for everyone, and always have been due to the fact that having greater cognitive ability is a large factor in success at most tasks.
Coffee (caffeine) is the most consumed nootropic in the history of the planet, and is probably the safest. There are probably a number of other equally useful yet harmless compounds out there that are ripe for discovery, but I wouldn't exactly put my money on the options that this article suggests.
I've experimented with nootropics extensively, and here are some of my findings:
1. Piracetam makes me very spacey and distant
2. Modafinil is good for staying awake without jitters, but otherwise useless
3. Adderall is too stimulative and leads to jittery, coked-out thoughts
4. Caffeine is a winner
5. Weed improves creativity but makes tracing the logical steps of your thoughts more difficult
6. Fish oil helps reduce skin dryness but nothing else that is detectable
