DarknessIsMyFriend, with respect I am sceptical about the link that you provided.

It uses a lot of impressive-sounding "sciency" phrases (Long-Term Potentiation and intracellular second messengers are examples) - both have precise meanings for biomedical scientists.

I can't find any evidence in that link that the various products that it sells have any effect on Long-Term Potentiation and intracellular second messengers.
