L-Glutamine - Does It Work To Repair Your Gut?
0

14 posts in this topic

My Naturopath wants me to take L-Glutamine between meals to help repair my gut. But I have read that the body converts L-Glutamine into Glutamate, and that you shouldn't take L-Glutamine if you have a reaction to MSG. I know that MSG gives me a headache and makes me feel drowsy and awful.

I don't know whether this information about L-Glutamine is correct or not, but I read it in several places around the web.

I have also read that it's a good idea not to eat too many foods that are high in Glutamate and Aspartate, because they can cause pain and neurological symptoms in high quantities.

Does anyone know anything about this subject? Is L-Glutamine OK to take several times per day between meals for a person who is an over-methylator?

This over/under methylator stuff is kind of whacky. I don't really buy it becasue there isn't any good science to support it. Even if it's meaningful, the conversion of glutamic acid to glutamine is not a methylation reaction.

Glutamine is safe to take. You only convert glutamate when your body needs it, since it's a neurotransmiter. That's why MSG can be hard on people; it over-rides your body's control of the glutamine conversion.

MSG is safe for many people, but troublesome for others. If you are MSG sensitive you need to avoid both MSG-containing additives and foods with natural MSG to the extent that you feel better. Some people do OK avoiding concentrated MSG; others are so sensitive that they can't eat foods like mushrooms, peas, or tomatoes.

I was hoping SkyLark would weigh in on this, because she really knows this stuff. ;)

I take one of the L-glutamine supplement tablets every other day or so. I know it helps heal the intestine, but I react to MSG very strongly, so didn't want to over do it. I have read that some people do get a reaction from the supplement.

I have Vitacost brand here, which is 1000mg. The directions say to take 1 tablet daily wih a meal. That bottle is nearly gone so I ordered a new bottle..different brand. It's Spring Valley 500mg. It says to take 1 or 2 tablets 1-4 times a day with a meal.

Taking it several times a day might be a bit much IMO?

How much you take will depend on the mg of the tablets you have. Maybe start with 1 tablet with a meal for a couple of days and see how you tolerate it? You can increase your dose if you do ok..but if you start out on that high of a dose it *could* give you a reaction that you'll have to ride out. IMO it's better to go a little slower with some of the supplements?

This is really great advice. There is rarely a reason to jump on a supplement really quickly.

Unfortunately not a lot of research has been done on glutamine and a lot of what is listed about it, regarding the dangers, is mostly theoretical. I personally have been taking it for about 2-3 years and it has definitely helped a ton. That being said, it hasn't been without some potentially serious side effects. The biggest danger for me was when I would take too much, I would seriously depressed, almost suicidal. But that was only when I would take too much, I think finding the right balance for each individual is the real hard part. The amount for me is 2 grams roughly every 48 - 60 hours.

So basically what I think it comes down to is finding out how much your body needs. If it's low and deficient in glutamine, you're probably going to need a lot more than 2 grams every other day.

Overall, glutamine is about as safe as any supplement gets. I would be extra careful if you are prone to depression or bipolar disorder however.

I would also recommend taking the powder form as opposed to the tablets. I have tried both and the power form seems to work better. I think this is because when you take it with water, it is spread out more evenly throughout the small intestine. As I'm sure you know, it is the primary fuel source for the cells lining the small intestine, so you want to spread out your dose evenly through your GI tract.

It's interesting that you would say that L-Glutamine would cause depression, when it is a pre-cursor to Seritonin. So in theory, it should help depression, not cause it. Yes, I do have a tendency towards depression. High EPA Fish oil has helped me a lot in that regard.

It's hard for me to totally judge my mood right now, because last week I learned that I tore cartilage in my hip and will need arthroscopic surgery. It has sent my life into a tailspin and I have been very upset the past few days.

I will keep an eye on my mood. It's hard to feel happy at the moment with this situation regarding my hip. But if I feel awful in general then I will certainly stop taking the L-Glutamine. It doesn't take much to get me feeling depressed. Once I was taking 2 Aleve every day for back pain, and it made me extremely depressed in a very short period of time. The depression went away when I stopped taking the Aleve.

The methylation stuff is, I think, strongly based in science. I have seen lectures and read about the methylation cycle. Dr. Amy Yasko does amazing stuff regarding methylation with autistic kids in the northeast.

You are the best judge of how foods/supplements make you feel. We are all unique, so it's hard for another person to tell you what will be right for your body. I hope you find the right dose that will help heal you, without causing bad side effects.

With an upcoming surgery I can completlely understand your anxiety. It's good they can do it arthroscopically. At least you won't have a huge incision to heal as well? Best wishes to you for a speedy recovery on both issues!

My bad. I plugged it into google and came up with some pretty dodgy stuff. I went and looked up Amy Yasko's work and it is impressive. Did you get the genetics testing done?

I didn't see the glutamate/glutamine conversion in the stuff they're studying. It's not a methylation; it's an amidation. Also glutamine is not the precursor to serotonin. Tryptophan is. That said, just about any of the neurotransmitter-related amino acids can have effects on mood. I just remembered my naturopath psychiatrist friend gives glutamine for its anxiolytic and slightly sedating properties. Most people find it helpful as far as state of mind, but obviously stop taking something that makes you depressed!

Good luck with your hip surgery. If you're a supplement fiend like I am, you might start onto some MSM to lower inflammation and help healing. I hope your surgery goes well!

It gave me 6-7 bouts of diarrhea per day and made my small intestine hurt under my rib cage. Took me too long to figure it out. Hope I can recover.

Yikes! You have been a member since 2004. Do you have celiac disease? Why would you take this supplement now? How long have you been taking it? Have other things been ruled out like gallbladder disease?

The functional Medicine doctor I work with uses l-glutamine as part of his plan for gut healing.  One friend of mine felt it healing when she took it.  I took it too late in the process to notice much, but my bloating seemed to be helped.  It gave me no adverse effects.

   I have Asperger's also, and I've used L-Glutamine.  It can be sedating- that's one of the things its used for.

What do you mean you took it to late in the process to notice much, is that because you were already healing?

Also can you tell me more about the Functional Medicine Doctor;

1 how they differ from a regular doc

2 how you found one

 

Thanks Diane

    • I already did. Thats how i found the place. Its amazing to actually go to a restraunt again.
    • This is EXACTLY what happens to me. It has twice now and both times was after both glutening episodes but once it was the day after and the other time it was a week and a half. So I'm still not sure if it's related or strange bug bites...

      Did they stop happening when she stopped being glutened? Did you decide they were definitely related? I'm really confused by this and would love to know whether to insecticide my house or....
    • Thankyou both! I was wondering if my high levels left much doubt on the diagnosis. I don't see the GI until the 15th Sep and I don't think I can stand to eat gluten in that time. If he tells me to I will do so after then. After 25 years of symptoms I don't think there is much chance of healing my bowel In a couple of weeks. I'm actually terrified of the damage they might find. But I think I will need the endo since there may be other things going on with me. So great they didn't put your son through the biopsy! Once I have a formal diagnosis I have my kids to worry about also. I can't even stand the thought of my daughter having a blood test. I think she would need to be sedated as she is so fearful and pain sensitive. My son is not yet 2 so I don't think they will test him. I'm feeling so off at the moment. I think I have some anxiety and reflux going on complicating things quite a bit.
    • My son's antibodies were 300. Based on his extremely high levels, his pediatric GI suggested genetic testing instead of the biopsy. Genetic testing can't diagnose celiac on its own but combined with such high levels, the gi dr was confident a positive genetic test would confidently diagnose celiac. He warned that biopsies are small snapshots of the intestine and can miss damage. He said this is an approach used very often in Europe but not as much in the US. What sold me on that approach was the ability to put my son directly on a gluten free diet instead of waiting three weeks for the biopsy, during which time he would continue to eat gluten and feel terrible. I'm not sure if this is more common with younger patients though (our son is two), based on the idea that he's had less time to inflict damage that would show in a biopsy? We are very happy that we immediately started the gluten free diet and chose the genetic testing. Our son got the proper diagnosis and his recent number shows a drop to 71 after only 4.5 months gluten free! Not sure if this helps. Good luck and I hope you feel better soon!
    • We have been off gluten for a while now, and symptoms return when I've allowed gluten full meals… so something still isn't sitting right with me.  Checking with her doc about seeing a pediactric GI although I'm not sure how long that will take since we live in small town America. I know she didn't get at least one of the recommended full panel tests but maybe two, can someone help clarify, or is she missing two? DGP for sure and possibly EMA? And if I understand what I'm reading in other posts that the DGP can be more accurate? Thanks Her blood panel results: Ttg ab iga <.5u/ml ttg igg <.8u/ml aga ab iga <.2 u/ml aga an igg <.7u/ml iga 61mg/dL
