<<Disclaimer: Verify this information before applying it to your situation.>> To the ones of us that are very sensitivity to gluten and other chemicals, I've come up with a few things the last few months that have really helped me. I've been able to track down the things that bother me because of my very very sensitive knees. With even a small hit of gluten or MSG or copper yes copper my knees will hurt for hours. I've tested my well water in the Lab at work trying different thing s over the last frw months. Water directly from the well before it goes threw the copper pipes is OK. The water will pick up enough copper threw the copper pipes that it is easily measured with instruments in the lab. Be careful with hard water it will give you erronous readings. My mother has also noticed the same improvement after removing the copper from her water. It may be just our gene line I have never heard of anyone else being sensitive to copper. If you want to write and tell me how crazy I am please feel free. I've had doctors tell me that before. The second thing that really helped is increase the amount of fiber per day I take in. After each meal I take half the recommended dose on the container. Metamucil is OK . I called to check The wafers have gluten but the mix for liquid is OK. Keep those letters coming I'm reading every one. Gluten free in Tennessee
