<<Disclaimer: Verify this information before applying it to your situation.>> Thank you all for your response regarding the supplement Ensure and Ensure Plus to take along on my ten day Kayak/Camping trip. The consensus is, that all Ensure products regardless of flavor are GF, as several people have verified with the manufacturer. I also received recommendations to try the supplement "Boost" because the taste may be less medicinal and the product "Sustacal" and "Nu-Basics" bars by Nestle (formerly Clintec).They are allegedly all gluten free I received a good tip for gluten-free MREs. (Meals Ready to Eat) The company is MY OWN MEALS, inc.(847)948-1118, it sells kosher MREs to the US Army and also sells them to civilians. A number of their products are gluten-free, do not require refrigeration and have extended shelf-life in Camper's Pack foil pouches. A list of the Nutritional-values Ingredients and Price is available from the company. John Knoll
