Crohn's supplement (didn't help, but didn't hurt)

Posted by iHerb Customer on Jan 24, 2014 | Verified Purchase

I bought it to help my Crohn's and it didn't really help, but I am leaving a high rating because it did seem to be a better quality than other brands that I tried. For instance, when dissolved in water, it dissolved better.

Thanks for your feedback!

Not Just For Body-Builders

Posted by iHerb Customer on Jun 23, 2012 | Verified Purchase

Although most people think of L-Glutamine as a supplement for athletes and body-builders, it also has a cumulative soothing effect on certain gastric problems such as GERD and IBS. Someone told me about this when I was searching for a natural remedy for these problems and I discovered that it really does work. This powder form is less expensive than the capsules and one jar goes a long way.

This is not the best glutamine

Posted by TinVal on Mar 06, 2012 | Verified Purchase

This glutamine is not USP/Pharma grade. I send e-mail to SourceNaturals and they told me that this glutamine is made from corn, not bacterial fermentation... Actually this glutamine dissolves very well and work great but is not pharma purity and I give 3 stars
