Sports people have known about the positive healing effects of L-Glutamine for several years but it has been increasingly used in products that have been specifically designed for people who have coeliac disease. Most of these products are extremely expensive and often quite difficult to acquire. There also is the added problem of how much l-glutamine do these products contain and whether they contain a reasonable quantity? Perhaps it might be a better option to purchase the pure supplement as a stand-alone item.
L-Glutamine is a natural amino acid. This amino acid speeds up healing of the intestines and helps to cure a leaky gut.
For those wishing to purchase L-Glutamine then please shop around. Firstly, there are different qualities and secondly, the prices vary enormously. Here are just a few links - but if you have a reputable health shop fairly near then do check out what they have available and the strength of what they supply. Most of all be aware that it will not be suitable for everyone, we are all individual and so therefore it should be taken with caution initially and if it doesn't work for you (if it makes you feel unwell) then it is essential to stop taking it. Make sure that the L-Glutamine that you buy is gluten free.
WARNING: ALTHOUGH TAKING L-GLUTAMINE IS MOST PROBABLY BENEFICIAL IN AIDING THE HEALING PROCESS WITHIN BADLY DAMAGED INTESTINES IT WOULD BE SENSIBLE TO DISCUSS THIS WITH YOUR DOCTOR SO THAT THEY MAY ADVISE ON WHETHER IT WOULD BE SUITABLE IN YOUR CIRCUMSTANCES AND ALSO OF PREFERRED USAGE AND STRENGTH. You may also find that L-Glutamine may be available on prescription in your particular circumstances.
Previous threads relating to L-Glutamine here on GFG:
I would advise if taking immunosuppressants or heart medication to check out with a doctor before trying out any supplement as although some are competely safe others do interfere with medicines or drugs.
Attached is a site with some indications just to give some idea but please do check with a doctor first ..
Sometimes it seems GFG is an advert for H & B - why consume supplements when eggs (especially egg protein), beef, chicken, fish, soybeans and dairy are naturally high in glutamine - whey has one of the highest sources of the amino acid glutamine found in nature and is a complete protein - and should have lactose and fat filtered off. Consuming whey protein powder helps to adds bulk when weight training (been there, done that).
But it's not just the expense of the pills, or the risk of there being a gluten bulking agent used - there are cautions to l-glutamine supplementation: It seems anyone sensitive to monosodium glutamate (MSG) should avoid glutamine supplements, as the body can convert glutamine into glutamate.
People with bipolar disorder should use glutamine supplementation with extreme caution as it has caused mania. For epileptics, some of the newer anti-convulsants work by blocking glutamate.
Diabetics should be cautious when considering L-glutamine supplements, as excess glutamine is converted into glucose in the body, according to the website "Creatine Journal." Glutamine may contribute to the development of type 1 diabetes and other autoimmune conditions, by virtue of its ability to promote white blood cell activity, according to Philip C. Calder, editor "Nutrition and Immune Function."
Hi Jacks, I appreciate your additional information on this. I did heavily recommend talking it over with a doctor. There are supplements that are in powder form and these, in certain instances, must be worth considering especially if a person knows they are not healing. When supplements may be questionable then medical advice on an individual and personal one to one level is always the best option. I merely added the post as an informative piece of news that is current and being discussed across the world as a possible help for coeliacs who are having issues with repairing their intestines.
I found your information about bipolar and MSG particularly interesting as I haven't come across those points on the Web. Also your diabetes type 1 reference. I know that athletes and weight lifters are according to their sites using it for muscle repairs.
Have you any more information that may be relevant about it? It would be good to see other perspectives here too!
My hubby takes Glutamine as part of his exercise routine and I looked at the site that he uses to buy his products. This stuff is completely Gluten and Lactose free so might give it a go and see if it works. They also do a powdered version that can be added to juice/water but need to email the company to see if its GF.
Id just like to add that when I attended a nutritionist many years ago when I was having a terrible time with diverticulitis she advised me to take Glutamine, she cautioned me only not to take it for ever but to take it for a few months. I had asked the doctors if they could recommend anything but they had no answers. It certainly helped me, and I took it for quite a while and as she said, once you are on the mend you can I stop it, which I did. I can only say it worked for me and I was very grateful for the advice. Maybe not for everyone, but it worked for me! I still take it occasionally.
