I have used Jevity almost exclusively for over a year and 1/2. As Gary said, the advantage of Jevity is that it has a special kind of added fiber, which really helps when you are udnergoing treatment and taking pain meds which can constipate you. You won't see it in the stuff as you pour it in your tube (which could clog the tube) but it becomes fibrous when it hits stomach acid (or any kind of acid--so don't pour acidic juice on top of it in the syringe or it suddenly becomes too thick to go down--I know this from experience).

The Jevity I use (1.2) is not a weight gain formula but a high protein firmula, and protein is essential to healing. But they have several different formulas. I lost a fair amount of weight since going on the tube (@50 pounds--30 lost during treatment and right after, but 15-20 lost in the year and 1/2 since) but I was overweight to begin with and no one has told me I need to gain weight back yet. The high calorie forumulas often do not have as much protein so ask your doctor what is right for you.

Also, so far my insurance has paid for my Jevity (minus a deuctable at the beginning of every year).
