I was wondering what you think of Phosphatidyl Complex (usually I see Phosphatidyl Serine for brain, Phosphatidyl Choline for liver, etc). I saw it in one of those combination nerve support supplements and also a few posts on brain health. The blurb about it on the supplement page said "Phosphatidyl Complex contains lipids that comprise 76% of the myelin sheath" which I found interesting. Have you researched this supplement? Any thoughts if it may help with remyelination (particularly after a needle based nerve injury)? It's a bit of an expensive supplement so I was wondering if it's worth it.

The body makes this itself, from the substrate Choline. Our diets tend to be low in choline in the US. It is now added in some children's vitamins for this reason. (to help with CNS development and learning). I am unsure as to how useful it would be for you, as PS is usually used for CNS issues.

One of the best food sources of choline is egg yolks. Much less expensive that way. Phosphatidyl serine is quite expensive.
PS is rather benign and not harmful, if you want to spring for it and try it however.
