Hi, Marcus:
Yes, I have used colostrum, but since dietary factors are so complex--and I nearly always do and eat more than one thing at a time with the purpose of intestinal healing...uh, I guess that results just 'got lost.' To this extent, I don't recommend this supplement because I have not given it a fair trial, but there are many other things that we should take--especially healing foods--that are considerably less expensive and at least as effective.
I'm certain that my intestinal healing, although a constant/dynamic process, has progressed even after many years of NSD, since I seem to have become more tolerant of 'borderline' foods.
So, I don't want to discourage you from the colostrum, especially based upon the claims of others with LGS, but there are many other important agents that should not be excluded over this one.
Good luck with it,
John
