I just watched the rest of Dr. Becker's show on medicinal mushrooms ... he sells the cordyceps and a medicinal mushroom complex both [www.bioinnovations.net]. Sounds like this stuff helps with tons of stuff from cancer to autoimmunity to diabetes to digestive issues, on and on!
He says 3 grams a day TO START is a good therapeutic dose!!! He said you can take as much as you want because you probably eat more than that on your pizza! Makes sense, it IS food after all! I found some at vitacost too where I shop a lot, but I'm sure they're sold all over the place. Just good to find a brand/company you trust.
