<<Disclaimer: Verify this information before applying it to your situation.>> So far most of you have said that I should take L-Glutamine to help heal my leaky gut. The recommend dose seems to be one 500mg capsule with each meal (3x day). It has also been recommended to take one probiotics with each meal. Several of you have been taking L-Glutamine for a long period of time with good luck. Some of you said you take two a day (a.m. and p.m. meals). Others just take one a day. I found a lot of information by searching the internet that points to a great benefit in healing leaky gut by using L-Glutamine. I did not, however, find anything (by physicians) that indicated the recommended dosage. If I receive any other info - I'll pass it on. Thanks to all of you for your replies. Jill/Texas
