L-glutamine: Good Or Bad?

I read that some people are taking amino acid L-Glutamine to promote small intestine healing. Well we are certainly all for that. For myself, I'm hoping someday my intestine will generate lactase again.

But I've seen conflicting information on glutamine. This is an excerpt from one post on this forum

----

The damaging proteins are particularly rich in proline and glutamine (especially the amino acid sequences which are in the following orders: Pro-Ser-Gln-Gln and Gln-Gln-Gln-Pro). As peptides, some such as 33-MER, cannot be broken down any further. In people with celiac disease, 33-MER stimulates T-cells to produce antibodies. The antibodies, in turn, attack the villi in the small intestine, reducing their ability to absorb nutrients. It is important to note that these sequences are NOT found in the proteins of corn and rice."

Personally, I've been gluten-free for two years, and within two weeks of taking L-Glutamine, I started losing weight again, and my stools were getting sticky again. The L-Glutamin I was taking claimed gluten-free on the bottle. So I stopped and a week later, I'm feeling my old gluten-free self.

Being a software engineer, I don't understand any of this... Can someone put this in layman's terms?

Has anyone seen a long-term gain from L-Glutamine?

Thanks,

Bob.

Hi Bob,

I was recommended it when I was first diagnosed, and starting taking it. My liver levels went from relatively normal to soaring over 800 (they should be below 40).

As soon as I was off it, they went close to normal again (they are still a little high, but just about 150... Not 800!)

That's evidence enough for me that it wasn't the best choice. There are a few debates on the forum about this if you use the search.

I use the Rexall brand from WalMart with no problems. I feel better on them than off.

I hope more people post on this subject. I have been taking L-Glutamine for some time - just as a preventive major, in case of accidental cross contamination. I only take one pill in the morning. I am wondering if my energy levels started dropping around the same time I started taking it. Three months after I started it, I started having constipation problems, which I had not expierenced since going gluten free a year and a half before I started the L-Glutamine. I never thought that there might be a correlation and now I wonder.

I just started taking a L-glutamine supplement and have been feeling worse. It is made by TwinLab. I'll have to stop/start taking it again to double check.

I think L-glutamine is a really good thing for your body to help heal. I was on that for a while to promote the healing of the intestinal lining.

There is another sequence of amino acids that also stimulates CD4 T-Cells to attack the intestine. That is found in the article Open Original Shared Link

That was found back in 2000 but the interesting part of this is that the immune system doesn't attack the amino acid sequence until an enzyme (tTG) comes along and puts in GLUTAMATE right in the middle of the sequence. Why is this interesting? Glutamate happens to be implicated in the cause and progression of Parkinson's disease. If you notice a recent thread on this website, many people have a parent with parkinson's who showed symptoms of celiac. Glutamate has been shown in deceased Parkinson's patients to have plugged up and/or altered the structure of the Blood-Brain-Barrier (the protective sheath of endothelial cells that is supposed to keep out damaging stuff circulating in the blood). If a BBB (blood-brain-barrier) is warped or altered by glutamate or something then of course a person is going to become sensitive to a whole host of foods and substances because they are getting in where they shouldn't be.

Hi Dan,

Thanks for your response from the other thread on Parkinsons

I have done some reading on MSG and wow you have me convinced. Then I came across another thread from this site that a member Rachael has talked a lot about her problems with MSG and she recommended the website MSGmyth which was helpful and I may order the book for recipes but what else is safe to eat? In terms of like food staples or basic stuff? Are there any more webistes you can suggest?

Just to add yes there are times when I did seem to have an intense reaction to emotional issues in my life but not sure if it could be considered out of the ordinary?? but maybe it was the antidepressants doing there thing? not sure?

I have been taking L-Glutamine since last september. I actually just stopped last week because I was having surgery and the strange thing is I feel better. But it was gall bladder surgery so I don't know. Ugh! this stuffis so confusing.

I am embarassed to say that I don't understand much of the above posts. I think I need it in "L-Glutamine for Dummies" language. :P

I have a friend that has been studying amino acids, what they are used for and what they will do for your body. I have taken a few and have given some to my daughters. One thing that she is constantly telling me is that amino acids should not be taken constantly. YOur body naturally produces amino acids, when you have lower levels, you take the extras for a boost until your body regulates itself and then you stop taking the amino acid- regardless of which one it is. If you are taking too much then you will begin getting the reverse effects. I had been giving my daughter, who is gluten intolerant, an amino acid complex. She took it for about a month and a half and did fine. Just this week I have noticed some regression of symtoms so I took her off of them and she is doing well.

Another example of this , my friend was taking tyrosine for tiredness and lack of energy, it helped a lot at first but after a few weeks she began getting really tired again. She got off of the tyrosine and is fine now. Amino acids should not be taken for months or years at a time - as I have stated too much of one will cause an imbalance and give you the opposite results. Some people need that reregulating boost for a couple of weeks or a couple of months, but generally no more than that. I am by no means an expert in this but this is my basic understanding from someone who has become well versed and experienced in amino acid therapy.

Hope this helps.

God Bless!

I really don't know why I chose to talk about glutamate in this thread (not enough sleep maybe). Anyways you can message me or make a new thread for everyone's benefit.

I highly recommend the book "Excitoxins --The Taste That Kills" by Dr. Russel L. Blaylock, Nuerosurgeon. His stuff is quoted by many doctors online. A good sample of the book can be found at: www.aapsonline.org/jpands/hacienda/excito.html

This MSG thing is really pretty scary. Powerful business is pushing it, but I don't want to get started on the FDA conspiracy thing. Online sources claim that any prepared foods that say "natural flavors" or "spices" or "extracts" or some sites even claim that anything that has been enriched with vitamins contains MSG. I don't currently know how much of all this is true but I'm going with the consensus on the web. I would like to be able to find a few industry professionals through the web and get their comments on how prevalent is MSG added to foods.

These are some thoughts; please take at face value as an offer for clarification with no guarantees for accuracy, either on my part or on the part of the authors cited.

=====================

Summary of below:

=====================

- Glutamine helps to repair intestinal damage if it exists.

- Glutamine may become "conditionally essential" (that is, your body may require supplementation) during certain disease states/healing/etc.

- Short-term/as-needed use is thought to be safe in otherwise healthy (ie, no serious organ problems) people (for celiac disease, just make sure it is gluten-free).

- Long-term risks, if any, are unknown; it would be reasonable to assume its use is only needed for active recovery from damage, after which your body should be able to make what it needs from there.

=====================

Explanation of DNA structure and what Glutamine is:

=====================

Most of the body's functions occur through proteins. The function of the protein has much to do with its three-dimensional folded structure. Gluten itself is a composite of two proteins.

Proteins are made up of amino acids. Amino acids are made up of bases.

- DNA is made up of four bases (A,C,G,T) in different three-letter combinations.

- Every three bases are interpreted to make an amino acid(eg, CAA and CAG make glutamine; UGU and UGC make Cysteine).

- There will be a region that marks "start" and a region that marks "stop". The body continues to interpret these three-letter codes, making amino acid after amino acid, creating a longer and longer chain of amino acids until it is told to stop. Most are very, very long. (Just a made-up example, Ala-Cys-Asp-Glu is what four in a row could look like, although I'm not sure that particular sequence is meaningful).

- This resulting chain of amino acids is a protein that has some use/function in the body.

From http://en.wikipedia.org/wiki/List_of_standard_amino_acids:'>Open Original Shared Link:

"There are 22 standard amino acids, but only 21 are found in eukaryotes. Of the twenty-two, twenty are directly encoded by the universal genetic code. Humans can synthesize 11 of these 20 from each other or from other molecules of intermediary metabolism, but the other 9 essential amino acids (histidine, isoleucine, leucine, lysine, methionine, phenylalanine, threonine, tryptophan, and valine) must be consumed in the diet. The remaining two, selenocysteine and pyrrolysine, are incorporated into proteins by unique synthetic mechanisms"

In the purest sense, it is not the amino acid that has an impact, it is the combination of amino acids (more properly, the final, folded, three-dimensional protein) that has a function.

Here are the amino acids: Open Original Shared Link

=====================

What does it do?

=====================

A few Wikipedia highlights on Glutamine:

"Glutamine plays a role in a variety of biochemical functions including:

* Protein synthesis, as any other amino acid.

* Regulation of acid-base balance in the kidney by producing ammonium.[3]

* Cellular energy, as a source, next to glucose.[4]

* Nitrogen donation for many anabolic processes.[2]

* Carbon donation, as a source, refilling the citric acid cycle.[5]"

"The most eager consumers of glutamine are the cells of intestines,[2] the kidney cells for the acid base balance, activated immune cells[7] and many cancer cells.[5] In respect to the last point mentioned, different glutamine analogues such as DON, Azaserine or Acivicin are tested as anti-cancer drugs."

"In catabolic states of injury and illness, glutamine becomes conditionally-essential (requiring intake from food or supplements). Glutamine has been studied extensively over the past 10

Did you see that warning from moderators not to bump old threads? This is exactly what they were talking about.

Hi Clock,

Thanks for the info on the Glutamine. I have been having severe problems with hypoglycemia since I restarted the glutamine. It makes sense.

      Welcome to the celiac.com community, @JudyLou! There are a couple of things you might consider to help you in your decision that would not require you to do a gluten challenge. The first, that is if you have not had this test run already, is to request a "total IGA" test to be run. One of the reasons that celiac blood antibody tests can be negative, apart from not having celiac disease, that is, is because of IGA deficiency. If a person is IGA deficient, they will not respond accurately to the celiac disease blood antibody tests (such as the commonly run TTG-IGA). The total IGA test is designed to check for IGA deficiency. The total IGA test is not a celiac antibody test so I wouldn't think that a gluten challenge is necessary. The second is to have genetic testing done to determine if you have the genetic potential to develop celiac disease. About 30-40% of  the general population have the genetic potential but only about 1% actually develop celiac disease. So, genetic testing cannot be used to diagnose celiac disease but it can be used to rule it out. Those who don't have the genetic potential but still have reaction to gluten would not be diagnosed with celiac disease but with NCGS (Non Celiac Gluten Sensitivity).  Another possibility is that you do have celiac disease but are in remission. We do see this but often it doesn't last.

      Hi there, I’m debating whether to consider a gluten challenge and I’m hoping someone here can help with that decision (so far, none of the doctors have been helpful). I have a history of breaking out in a horrible, burning/itchy somewhat blistering rash about every 8 years. This started when I was in my early 30’s and at that point it started at the ankles and went about to my knees. Every time I had the rash it would cover more of my body, so my arms and part of my torso were impacted as well, and it was always symmetrical. First I was told it was an allergic reaction to a bug bite. Next I was told it was eczema (after a biopsy of the lesion - not the skin near the lesion) and given a steroid injection (didn’t help). I took myself off of gluten about 3 weeks before seeing an allergist, just to see if it would help (it didn’t in that time period). He thought the rash looked like dermatitis herpetiformis and told me to eat some bread the night before my blood tests, which I did, and the tests came back negative. I’ve since learned from this forum that I needed to be eating gluten daily for at least a month in order to get an accurate test result. I’m grateful to the allergist as he found that 5 mg of doxepin daily will eliminate the rash within about 10 days (previously it lasted for months whether I was eating gluten or not). I have been gluten free for about 25 years as a precaution and recommendation from my doctor, and the pattern of breaking out every 8 years or so remains the same except once I broke out after just one year (was not glutened as far as I know), and now it’s been over 9 years. What’s confusing to me, is that there have been 3 times in the past 2 years when I’ve accidentally eaten gluten, and I haven’t had any reaction at all. Once someone made pancakes (they said they were gluten-free, they were not) and I ate several. I need to decide whether to do a gluten challenge and get another blood test. If I do, are these tests really accurate? I’m also concerned that I could damage my gut in that process if I do have celiac disease. My brother and cousin both had lymphoma so that’s a concern regarding a challenge as well, though there is a lot of cancer in various forms in my family so there may be no gluten connection there. Sorry for the ramble, I’m just doubting the need to remain gluten free if I don’t have any reaction to eating it and haven’t had a positive test (other than testing positive for one of the genes, though it sounds like that’s pretty common). I’d appreciate any thoughts or advice!

      Hello, just popped in my head to ask this question about medications and celiac? I have always had refurse reaction to meds since I can remember  of what little meds my body is able to tolerate. I was taking gabapentin 300mg for a week,  in past I believe 150? Any ways it amps me up not able to sleep, though very tired.However I did notice it helped with my bloating sibo belly.I hate that my body is that sensitive and medical doesn't seem to take seriously. Im STILL healing with my skin, eye, and now ms or meningioma ( will know in April  which)and dealing with this limbo nightmare. I did write my name, address ect on the reclamation but im not tech savvy and not sure if went through properly. I called my city representative in Stanislaus County and asked if theres a physical paper i can sign for proclamation for celiac and she had no clue about what I was saying, so I just said I'll go back on website. 
    • Scott Adams
      I'm not saying that some celiacs won't need it, but it should be done under a doctor's supervision because it can cause lots of problems in some people.
    • Jmartes71
      I also noticed I get debilitating migraines when I smell gluten, wheat and its not taken seriously when it affects one in every way.Im still begging to properly be heard.I also noticed tolerance level is down the drain with age and life changes. I have been told by incompetent medical that im not celiac or that sensitive. Diagnosed in 1994 by gi biopsy gluten-free ever since along with other lovely food allergies. Prayers
