We went with Neocate because that’s what our GI gave us. You can get Neocate with or without DHA/ARA. I don’t know what, if any, difference there is between the 2 other than that, but if you’re concerned about the DHA/ARA, you can always buy the supplement and add it yourself. I actually bought a bottle a while ago at Whole Foods and never used it. I read about it on this board, I believe it’s a liquid that you add a few drops or teaspoons (not sure of the dosage) into the bottles of formula. It’s still in the wrapper if you’d like to try it. Some people on this board think that the DHA/ARA upsets their LO’s, but, of course, most docs & the companies that make it say that there’s no real proof of that…hmmmm…
