Gail, I haven't looked at what vitamins are in each can of Boost lately, but I do know that consuming the amount of Jevity I do every day (the liquid stuff that's made for tube feeding), I get about what I'd get in a good multivitamin of C, E, etc. As opposed to getting, say, 1500-2000 mgs of vitamin C which is the level many people take (or higher) when taking it for antioxidant protection. The admonitions I got were against taking that kind of high level of antioxidants, not the lower minimum RDA level you'd find in a multivitamin.
