Phosphatidylcholine can be purchased in tablets too, which you rarely here about
it on this forum.
https://www.webmd.com/vitamins/ai/ingredientmono-501/phosphatidylcholine"Because the body uses phosphatidylcholine to make a brain chemical called acetylcholine, there is also some interest in using it for treating "brain-centered" conditions such as memory loss, Alzheimer’s disease, anxiety, manic-depressive disorders, and a movement disorder called tardive dyskinesia. But there is limited scientific evidence to support these uses."
The chemicals above are part of and in the Krebs methalation cycle. This seems to get stuck in some people, even if they are not low in choline.
Past Member "decarte" (MIA?) used choline (capsules) and some other stuff gathered from some people on Lyme Net I think it was? Maybe they got the idea from this PK Protocal? Oral pills are easy, not as effective though. Not everyone has Dr who will needle pump you with some protocol found on the net lol.
