PurePEA is manufactured in the Netherlands and can be found in protein powders in the US. I did find a link for purchasing this supplement in capsule form; seems it is used for many things in Europe(note the price is in Euros). I am just sharing information I uncover about potential alternative therapies--I am not suggesting anyone try this. My husband (who has PD) has not tried this. He just began a different supplement. I have not done enough investigation on PEA yet to have him trial this new supplement.
