Sarcosine, Carnosine, and Betaine are all identified as cheap tried and trusted treatments for a few spectrum disorders and prediabetes by the WDDTY.com medical research news website. Why am I telling you this? A lot of people in the mental health system run out of funds quite fast, many of the spectrum disorder drugs cause obesity, and none of those three treatments are proprietary patented medicine although they are are all expensively medically researched and reported. To say thanks, if you want to, for this free information just download my mp3 album I wrote at the links below and listen to all of my tracks. Good luck. High dose Viamin D has been researched by others for prediabetes.
