This thread is to collect all ideas and experiences to increase acetylcholine naturally, by whole foods or by cheap supplements. The idea is essentially, that acetylcholine is the neurotransmitter used by the parasympathic nervous system (and also by some parts of the sympathicus). Increasing it helps some POTS patients as well as anyone with sympathetic dominance and many people with digestive issues. For a long list of conditions where this might help, see this patent:

The idea to increase acetylcholine is best known via the Product Parasym Plus (though actually all the methods described in this post have been there well before Parasym Plus and well before the patent). I would prefer buying Parasym Plus cause it is tried by many people with POTS and seems to do at least some good for most:

For those not familiar with Parasym Plus: its a product by Dr Diana Driscoll, whos treatment approach is discussed in a balanced way here, containing both favourable and critical voices:

The ingredients are:

Alpha-Glyceryl Phosphoryl Choline, Aceytl-L-Carnitine HCL, Huperzia serrata leaf standardized extract 840 mg, Thiamin (as Thiamin HCI) 60 mg

Now, what should I do if I get polyneuropathy from even smallest amounts of B1 and if I generally poorly tolerate supplements? Also, I have seen posts by others who cannot afford 58$ for a 10d supply, whom I want to help with this thread. So what can we do? Here I make a start with suggestions to increase acetylcholine. They are what I like and tolerate: real foods. And essentially cost-free.
If you have an idea, please contribute just anything to increase acetylcholine naturally or by cheap supplements.
Here is a plain English description of the idea:
http://www.naturalbrainjuice.com/acetylcholine-key-unlocking-human-brains-cognitive-potential/
"To be simple, the brain essentially needs a choline molecule, an acetate (acetyl) molecule, and pantothenic acid (vitamin B5) to produce acetylcholine. You can get choline from eggs, acetate from vinegar, and B5 from eggs and avocados, or you can supplement for them. Alpha-GPC is my favorite choline donor, acetyl L-Carnitine is my favorite acetyl donor, and you can get straight pantothenic acid."
Now let's look at it in more detail if this really works and also a few practical hints:
1. vinegar diluted in water as a replacement for acetylcarnitine:
important: use plentiful of water to dilute it and drink with a straw. You may want to add a bit of salt too in order to buffer the acidity. All these measures serve to reduce tooth enamel damage to zero. You want to really get this issue completely out of the way as this "vinegar drink" needs to be tolerated every day several times. I have experience with that because I already took vinegar-water-drink years ago, for other benefits (great refreshment, gives energy and good mood, reduces ammonia). No damage at all while taking it for over a year. I put 10 ml tasty red vine vinegar into a glass of water, maybe some 1.5 dl or so. If you are histamine intolerant, you may want to use chemically produced acetic acid concentrate. Also you may want to pay attention to avoid vinegar with sulfite. Sulfite-free vinegar exists. And that is what I take.
Now, whats the scientific basis of this replacement?
The main ingredient in vinegar is acetic acid. This is just the same as the "avetyl-" in acetylcarnitine. acetylcholine is acetic acid + choline:
https://en.wikipedia.org/wiki/Acetylcholine
Now does all this vinegar we drink really contribute to acetylcholine in neurons??
As for peripheral neurons, I do not see issues, but lack a reference if they really take it up. For the brain, there is a hurdle to take: the blood-brain barrier. Fortunately, acetic acid crosses that successfully:

It was the following page that inspired me. One of the posts wrote that the acetylcarnitine simply serves to donate the acetylgroup:
http://www.longecity.org/forum/topi...-if-you-have-it-and-a-log-for-my-supplements/
"Acetyl L-Carnitine - it donates the acetyl- group to produce ACh"
2. dietary choline as a replacement for alpha-GPC
While many people eat plentiful choline, there is a considerable number who get too little.
Scroll down here and you find a fairly bad table of choline contents.

For more info on choline contents, see the post by
@Richard7 below.
If you want an easy to use software to compute your dietary choline intake, use cronometer.com. See my post several posts further below, with an example result. Crono is for free, though, I happily pay to support their great work.
Does anyone know a lab that tests for choline in blood?
I know only Spectracell's micronutrient test (MNT), which tests for choline in WBC. But first, the test is expensive and second it is not validated (but a smart idea nevertheless)
Now, will the choline we eat turn into acetylcholine in neurons? Fortunately, yes:
