Thanks for that Cort. I started using some of the supplements name checked by Hip after reading research from Robert Naviaux, Dikoma Shungu and Fluge & Mella.
Fluge & Mella suggested L-arginine but l-citrulline creates fewer digestive probelms and has a linger half life as it is broken down by teh kidneys to l-arginine which then converted to notric oxide which widens the blodd vessels.
Dikoma Shungu has trialled patients on 1000mg N-acetylcysteine and had good effects. (I have too). I wrote a page on it on MEpedia, which has links to the relevaqnt study and other resources. http://me-pedia.org/wiki/N-acetylcysteine
Robert Naviuax in his groundbreaking metabolomics study noted that patients (especially men) had depleted BCAAs. There is also evidence that Amino Acids are burned by the body instead of glucose due to metabolic problems.
