Well the colostrum will actually help heal the leaky gut and stop the immune issues but if you don't see candida "roots" (//www.curezone.org/ig/i.asp?i=50511)
In your stool then you probably don't have a bad leaky gut case. Leaky gut is caused by general inflammation which can be from low bacteria, heavy metals or pathogens. And so you know, candida can be in either yeast form or fungal form as seen in the link.
I wouldn't start glutamine until the candida is under control because candida damages the gut lining.
Things that cause candida; heavy metal toxicity, weak adrenal glands, low probiotics, Antibiotics and hormone imbalances.
