Like "Hello Tender you have asked a question that is very close to my heart. Glucerna is made by Abbott Labatories and it is designed for diabetics as a meal replacement. I went on it after my hernia surgery because I could not eat my three meals a day. I did so well on it that my doctor said it is fine to continue drinking one Glucerna shake a day, he also said it has everything that I need in it. If you should try Glucerna make sure you shake it a lot before drinking or it tastes like liquid vitamins. Abbott Labatories also makes Ensure, the Freestyle testing meters and the nutritional supplements for feeding tubes that are prescribed by MD Anderson cancer treatment center. They really seem to understand nutritional needs. Mary"
