For those who are unfamiliar with nootropics, they are supplements/drugs that enhance memory/learning/concentration.
Brief descriptions:
CDP-choline: A more effective form of
choline.
Alpha-GPC: Another more effective form of
choline. Some research indicates it is more effective than CDP-choline, but CDP-choline has a much more substantial research base.
Bacopa: An inexpensive adaptogen, don't know much about it, but I believe it is an acetylcholinesterase inhibitor. May also raise thyroid hormone levels.
Galantamine: An acetylcholinesterase inhibitor. Also has an effect on nicotinic receptors.
Huperzine A: Another acetylcholinesterase inhibitor. I like it more than galantamine because it has less side effects, is more selective, and offers additional health benefits.
Idebenone: This is a form of coenzyme Q10 that cannot become a pro-oxidant. A potent anti-aging nutrient. Relatively expensive.
Picamilon: A modified form of
GABA, supposed to be both simulating and anxiety-reducing at the same time. For those familiar with phenibut, this is similar.
Vinpocetine: Increases cerebral blood flow, has other properties.
