I've not heard of this nor it was useful for memory. Normally its considered to have cholinergenic properties and compliments piracetam/choline etc... Its cheap.
Yes, l-huperzine A is an acetylcholinesterase (AChE) inhibitor. Acetylcholinesterase is the enzyme responsible for the breakdown of ACh which occurs following its travel from the pre to post synaptic density. An AChE inhibitor enhances the activity of ACh by preventing its degeneration, allowing it to remain a functional neurotransmitter and increasing overall levels of ACh in the synaptic cleft and within the synapse itself. It is certainly inexpensive, and has been shown extensively in both animal and human models to enhance certain forms of memory and cognition. ACh is required in the hippocampus for short-term memory and consolidation, and is exhausted during these processes-- AChE inhibitors have been shown to prolong the period of activity for ACh and therefore enhance these functions.
DMAE is said to be anti-cholinergenic ... :dunno: I guess the wiki would be a help.
Very interesting-- DMAE is methylated in the brain to become choline, which is used as a precursor for the all-important neurotransmitter, Acetylcholine (as I am sure you know). Out of curiosity (I know that this is a statement you are referencing), where did you read/hear that? I am having trouble finding such a statement outside of a few discussion forums...
A hyper-cholinergenic response is (very) dangerous and is a risk when you are stacking different noots long term but you'd need more than whats happening here
This hyperchoingeric response is exactly the danger in high-doses of l-huperzine A. As an AChE inhibitor, l-huperzine leads to increased concentrations of ACh in the synaptic cleft, which can lead to overexcitation of AChRs, resulting in an excitotoxic reaction.
I am wondering if Piracetam and other NOOTs directly can make you smarter or if they merely improve focus/concentration which can be construed to be that they are making us smarter.
The short answer is, no.
Intelligence is measured by a number of variables, none of which are universally accepted. In day-to-day interactions, intelligence is commonly measured by variables which can, yes, be enhanced by the employment of nootropics: vocabulary, short-term recall, creative problem solving...etc. Some nootropics may also lead to enhanced synaptic plasticity and neuronal generation (in certain areas of the brain).
But no, nootropics will not simply make you a "smarter" person-- just like most supplements will not simply make you stronger. When combined with dedicated studying or other forms of education, nootropics may enhance the process of learning. Learning and memory, as well as most forms of cognition require the employment of the neurotransmitter Acetylcholine, and most nootropics act to enhance its activity (either directly or by inhibiting enzymes responsible for its degeneration [e.g. AChE]). From there, this becomes a discussion of complex neurobiology, which is probably best saved for another forum or a more personal discussion
So yeah, in some manner the use of nootropics may enhance intelligence... but its certainly a bigger picture than that :thinking:

Thats the key to all noots - the chances are what works for someone is unlikely to work for someone else.
Truer words have never been spoken regarding the use of nootropics. Nootropic employment is as unique as neurochemistry-- just as our fingerprints, no two brains are exactly the same-- and therefore no nootropic regimen is likely to be equally efficacious across the board.
Additionally, as discussed above, definitions of intelligence differ between (and even within) cultures, so methods of intelligence enhancement are unlikely to ever be universally accepted. As most nootropic users have different goals, what works for one individual may be useless for another. As with most psychoactives, your mileage may vary...
