Modulen is a Nestle product but it is NOT available in the US. If you go to the Nestle site, you will see you need to choose your country, and then you can see what is available.
The Nestle product availale in the US that was recommended to us is Peptamen (my daughter grades it really low in the taste level)
We are using Splash E028 from Nutricia (best rated flavors according to my daughter: orange pinapple and Tropical fruits.) .....Maybe that's because we live in Miami!
This formula is very similar to the one used in medical trails mentioned in the Oppenhimer book "Beat Crohn's...."
