I have been using l-Gluitamine for quite awhile now and I find it really helps strengthen the bones.

I have no comparison

Posted by Reviewer1795354 on Nov 14, 2011

I took two before bed on days of work our and one on rest days. Muscle soreness seems to be less because of it, so I guess it works. Since this is my first experiment with l-glutamine in general, I have literally no frame of reference here. I enjoy capsules, so that's good I guess.

Something is working very well for my husband & me, and this is one of the supplements we take, so....

I bought this supplement after reading that taking 2g of L-Glutamine before bed has been proven to cause an increase in HGH. I haven't had my before-and-after HGH levels measured, but something my husband & I are doing has significantly increased our energy levels, mental clarity and immune responses (no sicknesses since we started our low-carb, high nutrient, no-sugar regime + selected supplements a few months ago), so this one seems to be doing its part. We both take 2g of it every night before bed -- that's the recommendation I've read.

L-Glutamine is helping my Crohns disease

Posted by Reviewer3201443 on Nov 08, 2014

I was diagnosed with Crohns in 2013. I've been on a hunt to find supplements to help with this disease. I have not taken any drugs. I checked out the Herbs and Supplements page on iherb under Links, looking for help. Regarding L-Glutamine, it states that "it appears to serve as a fuel for the cells that line the intestines". Also, there were two double blind trials using L-Glutamine; a total of 30 people enrolled in those trials without benefit. No mention of the mg's used. I decided to give it a try anyway. I'm half way through my first bottle of 1000 mg. I have only taken it once a day, first thing in the morning on an empty stomach. I am now finding that it works for me as far as having normal bowel movements. It hasn't curbed a lot of gut pain as yet; I hope it will in time. I have read reviews where more is taken throughout the day. I will begin to do that. I first, wanted to see if there was any improvement. I can say for a certainty, that there is! I hope this information will help others who suffer with this awful disease. It is worth a try.

L-Glutamine is highly effective on me but effect wear off after about 10 days. Really improve concentration 20 minutes after ingestion for about 1 -2 hours.
