Tell me more about this DMAE, what will it do for me while I'm awake, or do you take it before going to sleep?
It quickly metabolizes into acetylcholine, which is an important neurotransmitter in several parts of the nervous system. The effects I care about are in regards to memory, but it has other neurological functions in the brain. It also makes me stutter and stammer less, and it acts as a mild mood elevator--if I haven't taken it for a few days, I can definitely tell, although I wouldn't label it as full on depression, just a sort of pessimism.
The bad side to DMAE (specifically DMAE, not acetylcholine in general) is that there have been some studies that show it decreases the life span of certain cells in certain animals. That sounds kinda scary, but nothing conclusive is known. Just because it does that in some animals doesn't mean it will do it in humans.
Also, falling acetylcholine levels is linked to Alzheimer's disease, although I don't think it is known if that's a symptom or if boosting acetylcholine will improve things.
Acetylcholine can also be boosted much less efficiently with b vitamins. I think when done with b vitamins, it regulates how much acetylcholine you will get, whereas DMA bypasses certain steps in production.
