<<Disclaimer: Verify this information before applying it to your situation.>> I received about a dozen replies telling me not to use the product because it contains barley and oats. Two people recommended using a juicer to get antioxidants and one said it's best to eat whole fruits and vegs. I already knew better than to take these supplements, but was curious as to how the manufacturer could state in writing that they're gluten-free. The premise of this supplement is that it's difficult and expensive to eat enough fruits and vegs every day, so they have made capsules and other products out of juiced then dried fruits and vegs. Supposedly they contain all the vitamins, minerals, antioxidants, fiber, enzymes, and phytochemicals and therefore benefits of the whole plant. They claim to be gluten-free, HOWEVER, they contain BARLEY, BARLEY BRAN, and OAT BRAN. I called Natural Alternatives International (in TN) 901-366-9288 and talked to Dr. John Mori (biochemist or something, sorry I don't know exactly). He said they "receive barley bran and oat bran already in the bran form, separated from the kernel which contains gluten. Our product contains fiber, not gluten". I asked him about the grasses I had read about somewhere. He said the LITE meal replacement drink powder contains wheat grass which DOES contain gluten. He says he knows of celiac patients (I never told him I was celiac) who take the supplements "successfully". I told him I buy gluten-free products from companies who wouldn't DREAM of putting barley or oats in their foods. Bottom line, I am not convinced. I think they're out of their minds saying the product is gluten-free. I can't believe there would be no cross-contamination even if we could have the bran of these grains. Kris in Ohio
