I was diagnosed with fibromyalgia in 2000, and hypothyroidism in 2002. My doctor recommended I take unflavored gelatin to help with the "fibro-fog", saying it helps maintain the function of neurotransmitters in the brain. I used Knox Unflavored Gelatin for a little while but the cost was prohibitive. I found Great Lakes Gelatin online and have been using it ever since. I buy it by the case. It really does help, not to mention that it's super handy to have on hand any time a recipe calls for unflavored gelatin. I highly recommend this product.
