<<Disclaimer: Verify this information before applying it to your situation.>> I received a few replies to my posting about the Ness Carbohydrase enzymes. I followed up on these, and found that Ness makes a variety of enzymes, some of which can be purchased online at http://www.gaines.com/html/Ness/Ness.html . These are a weaker variety than the Carbohydrase, but they're also cheaper. Carbohydrase must normally be purchased from a practitioner. However, one person mentioned that they can be bought directly from Needs Nutrition, at l-800-634-1380. The price is $27 per bottle + shipping, which is pretty good. Another brand of enzymes that my doctor sells is "Bioset Sugar/Starch". These cost slightly less than Carbohydrase, but have twice the potency of Carbohydrase, plus you get 50% more capsules, making them a very good value. My doctor tells me that the Bioset line is also made by Ness (Enzymes, Inc). However, I don't know the GF status of this enzyme, and I haven't called Ness to confirm any of this information. I haven't even tried these yet, as my doctor is always running out. This is all I know about these products. Enzymes, Inc., can be reached at 1-800-637-7893, and they can provide more information. I have no financial interest in Enzymes, Inc. Pat
