Yes the acetyl choline is the chemical that the vagus uses as its neurotransmitter. So if we want to rehab the vagus, we need to make sure we have sufficient choline and also vitamin B5 to make it. ( stress uses up B5).

I am doing some further professional development into the effect of SARS- cov 2 on health even 2-3 years and more post infection. There are few tissues in the body that don’t have the Ace 2 receptor where the virus can have serious effects including our autonomic nervous system. This is why so many people have suffered from GI issues both affecting the gut itself but also the nerves serving the gut which largely is the vagus. Good tone in the vagus is highly anti inflammatory but it’s also innervating everything that needs to happen in the gut; from saliva production, hydrochloric acid, bile, pancreatic enzymes and so on. Rehabilitating the vagus is, imo, hugely important. 🤗

@Chris McCalla Sorry to hear about that. Fingers crossed you will get some rehab going on.
