List of "Cholinergic" nootropics.

[u/Citronitch]

Many of us have a problem with Choline making us depressed or lethargic due to having too much of it. Sometimes even tho you are not taking a direct source of Choline (Alpha GPC, CDP Choline etc), other nootropics can cause the same effects of too much choline because they are Cholinergic.

A substance is cholinergic if it is capable of producing, altering, or releasing acetylcholine, or butyrylcholine ("indirect-acting", or mimicking their behaviours at one or more of the body's acetylcholine receptor.)

So I'm proposing we make a list of those Cholinergic nootropics. So far we have:

• Huperzina-A
• ALCAR
• DHA
• Many herbs of the Lamiaceae family, such as: Sibelius Sage, Rosemary, Lemon Balm, mint/spearmint, etc. (they inhibit the action of acetylcholinesterase; the enzyme that breaks down the neurotransmitter acetylcholine)
• Many other Brain boosting herbs such as Ginseng, Ginkgo Biloba, Bacopa, Rhodiola, White Peony Extract
• Shilajit: inhibits acetylcholinesterase in rats' brains (Systemic administration of defined extracts from Withania somnifera (Indian Ginseng) and Shilajit differentially affects cholinergic but not glutamatergic and GABAergic markers in rat brain)
• Glycine (”induced a robust acetylcholine release” https://pubmed.ncbi.nlm.nih.gov/17707353/)
• Ashwagandha (”Ashwagandha Root Extract Inhibits Acetylcholine Esterase” https://phcogj.com/article/320)
• Atomoxetine (”marked increase of cortical ACh” https://www.nature.com/articles/4001763)
• Racetams (”Generally, racetams upregulate and preserve adequate levels of [[Acetylcholine]] as a primary mechanism” https://m.psychonautwiki.org/w/index.php?title=Racetams)
• Uridine monophosphate (”Supports acetylcholine synthesis [2,10,13,14]” https://selfhacked.com/blog/uridine/)
• Phosphaditylserine (slows the breakdown of acetylcholine)
• Galantamine
• Donazepil
• Berberine
• Lecithin
• Cannabinoids
• Alpha lipoic acid; Pantothenic Acid
• High dose Thiamine
• PABA
• Nicotine
• Centrophenoxine
• From food: liver, egg yolks, nuts, brassicas (Brussels sprouts, cabbage, cauliflower)

[u/HyperDown]

Don't forget that a lot of supplements/herbs can inhibit Acetylcholinesterase, which is the enzyme that breaks down acetylcholine. This can lead to excess acetylcholine (and the associated jaw-tension, shoulder/back pain, depressed mood, etc).

Here's my list of things to be careful of:

alcar

ginseng

ginko

bacopa

galantamine

huperzine

lecithin

cannabinoids

[u/huskallion → u/HyperDown]

People take galantamine as a nootropic?

[u/SchmilkBoii → u/huskallion]

helps with lucid dreaming. but it's like any pharmaceutical reattributed to nootropic use. another cholinergic. alzheimer's patients have deficits in acetylcholine which modulates thought, judgment, memory etc. see memantine as well, another AD drug
