Acetylcholine

Anyone else had any experience with taking precursors to acetylcholine.... acetylcholine is a neurotransmitter that regulates muscle tone, amongst other things..... some of the precursors include phosphatydil choline stacked with B-complex and an additional 500mg of pantothenic acid.... also lecithin, which is a natural source of phosphatydil choline along with being a fat metabolizer, DMAE is a precursor as well as being a vasodialator. There are a few more I can't recall at the moment..... the only natural source is fresh, not freeze dried, royal jelly... so the best option are precursors ... a bonus is increased alertness, focus and supposedly, even intelligence .......
I swear by it, but would like to know if anyone else goes this route,,,,
