Ummm, you could chew on some snowdrops, but I guess they're not really your typical foodstuff. My dog says Pop Tarts are chock full of essential amino acids and the pink ones have a novel acetylcholinesterase inhibitor, but then, he tends to make stuff up.
Eggs = good source of choline
Bananas = tryptophan
Dark Chocolate = PEA
.. and I just thought of a couple of others, but then I forgot. Where's those snowdrops...
Obviously eating the right foods is key for good health and wellbeing but when it comes to specifically nootropic effects it's hard to beat a good old lab produced powder.
This is interesting
