L-Glutamine Benefits

L-glutamine is one of those buzzwords in the fitness industry and seems to be highly acclaimed for its ability strip fat and build lean muscle tissue. In this post we will take a deeper look into L-glutamine’s benefits and side effects so you can decide for yourself whether this supplement is right for you.

 

WHAT IS L-GLUTAMINE?

L-glutamine is an amino acid needed in the body for the biosynthesis of proteins. It is the most abundant amino acid in our bloodstream and more than 61% of our skeletal muscle is made up of it, and 90% of our body’s l-glutamine is synthesised in our skeletal muscle.

However, there can be a problem sometimes with glutamine synthesis in certain individuals such as the sick, or premature babies, which makes it much harder for them to produce their own. In such cases as this l-glutamine then becomes an essential amino acid because of the body’s compromised abilities.

 

WHEN WOULD I NEED TO SUPPLEMENT?

Glutamine is crucial in your body, and is essential for providing fuel to your cells in order to make other amino acids, and to produce glucose. It is especially needed in times of stress, both physical and mental, as it will be burnt up very quickly under these conditions. This is one of the reasons why l-glutamine is so popular in the fitness industry as physical training puts constant stress on the muscles and immune system, and so a constant supply is vital.

When intensely training, levels of glutamine are vastly depleted which decreases overall strength, stamina, and recovery time. In fact, after an intense exercise session it can take up to 6 days for levels to return to what they should be, which obviously isn’t good if you like to train at least 3 to 4 times a week.

 

L- glutamine for Muscle Repair and Growth:-

Studies show that glutamine supplementation can improve the metabolism of protein, meaning it can also be used for muscle repair and growth – which is yet another reason why it is so popular with those on an intense training program, or lifting heavy weights.

 

L-GLUTAMINE AND FAT LOSS

weight loss

L-glutamine is definitely up there as a fat burner because it helps counteract the storage of fat, and so helps to regulate weight. It also reduces cravings for sugar and alcohol which are up there with the worst belly fat producing offenders, and belly fat specifically is the most dangerous kind to have in regards to health.

During intense exercise l-glutamine also helps with the process of outing fat WITHOUT losing vital muscle mass – something that is very easily done when exercising, and is often also a side effect of weight loss.

 

The Plant Based Diet:-

raw vegetables

All this can be negated with a few simple strategies and a proper eating plan, which is why I recommend an alkaline plant based diet and obtaining the bulk of your proteins from plant foods such as quinoa, nuts, seeds, pulses, and plant based protein powders.

Eating more alkaline foods will also help temper any chronic inflammation in your body, which will also in turn fasten up your recovery time after exercise. This, among many other amazing benefits, was one of the first and most prevalent things I noticed when I started focusing my diet mainly on plant foods.

 

L-Carnitine:-

L-carnitine is another amino acid that also has an impressive profile for fat burning during exercise, this is one thing among its many other benefits. The reason I mention it is because it is often used alongside l-glutamine for even more enhanced fat burning and muscle building effects, so it is worth considering this supplement alongside your l-glutamine. 

There are many other ways you can build muscle and burn fat and you should incorporate some of them into your daily regime and NOT just rely on one thing. You will always get the best fat burning, muscle building results by hitting it from as many different angles as possible that include diet, exercise, and sometimes added supplements.

 

EXERCISE AND THE IMMUNE SYSTEM

An intense workout (especially body building) depletes your stores of glutamine, and as glutamine plays such an important role in the immune system this can leave you more susceptible to catching bugs and other illnesses.

Who’s ever noticed getting sick after they know they have overdone it in the gym or out running? I know I have; pushing your body too far, too soon can really have a knock on effect on the immune system so it is vital to keep it strong and healthy with a supplement such as l-glutamine.

This in itself could be a good reason to use this amino acid, especially if you do like to push yourself during training, and of course pushing yourself is certainly something that you need to do in order to get stronger, fitter, and leaner. It’s just a good idea not to take this too far too quickly, not if you want to keep your immune system firing on all cylinders.

 

Other Uses For L-Glutamine

L-glutamine is also used in the medical world for many other reasons; one being as a protection for the immune system in patients undergoing cancer treatment such as radiotherapy. It is also used after bone marrow transplants and bowel surgery to improve recovery, prevent infection, and increase well-being.

 

L-GLUTAMINE AND MENTAL DISORDERS

L-glutamine can also be used in the treatment of various mental illnesses and disorders, such as depression, anxiety, insomnia, and ADHD. It has a stabilising effect, and unlike many other medications is able to cross the blood brain barrier. This means it may stimulate GABA, which is a neurotransmitter that sends chemical messages through the nervous system and brain, and the changing of these messages can result in relief from some of these disorders.

Although more research needs to be done in this field, as with many natural mood disorder treatments, sometimes it can be a case of trial and error to find what works for you specifically.

 

L-GLUTAMINE AND LEAKY GUT

Another very popular use for l-glutamine is for healing the cells in the lining of the gut that may have been damaged by LGS (leaky gut syndrome). LGS can often be a side effect of IBS (irritable bowel syndrome).

The inflammation that goes with this disorder can damage the intestinal lining. Experts are not sure whether IBS causes LGS or vice versa, and it is a field that still needs much more research and there is no real cure as of yet, not medically at least.

 

Other Issues Caused by leaky Gut:-

inflamed bowel and stomach pain

Having a leaky gut can cause so many issues in the body that it is fast becoming a leading chronic health issue. Some of the problems caused are auto immune diseases, skin problems, allergies, asthma, autism, arthritis, SIRS, and type 1 diabetes.

Symptoms of leaky gut include: inflammatory diseases, food sensitivities, auto immune diseases, malabsorption of key nutrients such as Vitamin B12, magnesium and other enzymes, and mood disorders including autism.

This is a long list of which I haven’t gone into much detail, but bottom line: it seems that leaky gut syndrome may be a root cause of many problems and certainly requires deeper investigation if you feel you may be suffering from it.

 

Healing A Leaky Gut:-

sauerkraut contains healthy, gut friendly bacteria

While l-glutamine may help to repair a leaky gut, this is only a small part of the healing process and there are other steps that involve the cutting out of certain foods. These include foods such as sugar, grains, non organic animal products, and alcohol, and then adding in healing foods such as live enzymes, and probiotic foods like sauerkraut and live yogurt cultures.

It is after this that you would begin the repair process and is where l-glutamane would come in with its abilities to heal stomach lining. After which you would then need to repopulate the gut’s good bacteria with a good quality probiotic. This process is called the 4 R System.

This is a process that needs to be done either under the supervision of a professional, or with proper understanding of it.

If you feel like having a go at making your own sauerkraut to help heal your leaky gut then please check out this video below.

WHAT AREL-GLUTAMINE BENEFITS AND SIDE EFFECTS?

  • Helps protein synthesis
  • Helps strip fat and promotes lean muscle growth
  • Is a great immune booster
  • May help with mental disorders such as depression and anxiety
  • May help combat insomnia
  • Has many medical uses (of which I would suggest you consult your doctor about before use)

 

WHERE TO BUY AND WHICH KIND:-

capsules

As with all supplements they are most definitely NOT created equal. Some are filled with preservatives, chemicals, fillers, and many more nasties, and if it is something you need to take long term then just think of how detrimental it would be to keep filling your body with rubbish. Many of these will have names that are unrecognisable so you don’t really know what you are putting in your body, or the potential side effects of this added junk.

Make sure to buy from reputable companies and brands. Here I have sourced out trusted brand that produce good quality l-glutamine.

Amazon: SOLGAR 500mg L- GLUTAMINE CAPSULES

 

Possible Side Effects:-

It’s important to ALWAYS read labels. Side effects are pretty rare and usually only occur when too much is taken, but they are generally mild and may include stomach aches and cramps, nausea, vomiting, mild skin rash, dizziness, itching and headache. If these occur then you should stop taking the supplement and consult your doctor who may suggest a different dosage, or to stop completely.

This sounds like something that I need! Mostly for insomnia. I have been having a hard time sleeping at night due to a prescription that I take, rendering me so tired during the day. I am going to head on over to your link and try this out. Heck the other benefits are not bad either. Boosting my immune system would be great as well.

    Stefanie Taylor · 06/11/2017 at 6:29 pm

    Hi Matts Mom, thanks for reading and yes I know exactly what it’s like not to sleep as I suffered insomnia for years until I got into health and fitness. Now it has greatly improved thank god. Yes, I recommend you give L- Glutamine a go to see how it works for you. Anything is worth a shot as what works for one may not always work for another as we are all different. Good luck and please do let me know how you get on.

    Another few tip for insomnia that worked for me is never drink caffeine after 3pm (it really does make a difference) and also, you may benefit from some magnesium at night as this helps relax muscles. Just make sure it’s a good brand! Other sleep herbs include Valerian, passionflower, vervain, lemon balm, lemon verbena an chamomile. You can often buy these in tea form or if you want stronger then supplements. Hope this helps and please keep me informed as I would like to know how you are getting on.

As someone who’s trying to shed a few extra pounds and is trying to get more into health and fitness, I found this article very helpful and informative. I’ll definitely be checking out those l-glutamine capsules!

    Stefanie Taylor · 06/11/2017 at 6:37 pm

    Hi Jose, glad this article was helpful to you and yes you should give them a try if you are in a serious exercise program, I actually would suggest taking the amino acid L- Carnitine with them as I said in the post for maximum benefits. And if you are only going to take one I would actually recommend you take just the l- Carnitine as it will work better to cut fat. Read my post on L-Carnitine here and decide for yourself.

Keith Hightower · 06/11/2017 at 5:17 pm

Enjoyed you post! I thought it was very clear–the benefits of L-Glutamine, and when it might be beneficial to supplement with it. I liked that you pointed out where more research was needed to determine the benefits in certain situations.

    Stefanie Taylor · 06/11/2017 at 6:32 pm

    Hi Keith, thanks for enjoying the article, yes I always like to be thorough in my posts and tell all sides of the story. Too many people are trying to make a quick buck and up selling products by being totally biased. Really annoying, I only want to promote products that I think can genuinely improve peoples lives.

Jaden Ho · 08/11/2017 at 1:58 pm

Such a splendid work you have done here. I had no idea L- Glutamine could helps with mental disorders, and your information about building muscle and fat loss because of L – Glutamine was very interesting. I need some L- glutamines to help me lose my belly fat. Thank you for your information.

Regards
Jaden

    Stefanie Taylor · 08/11/2017 at 5:03 pm

    Hi Jayden, thanks for reading and I glad you found the article informative. Yes L-Glutamine seems to be a great supplement for many things but remember that for est results, as with most things, you should always combine with a good fitness plan/regime and a healthy diet. It is never usually just one thing that will help with chronic issues, rather a culmination of different thing. You have to hit it from all angles so to speak. Good luck.

Melissa · 08/11/2017 at 5:13 pm

That is amazing information. I have never heard about L- Glutamine but you have definitely peaked my interest. One reason being I have insomnia which in my case can be dangerous because I can have seizures while I sleep so getting rest is essential. The other reason is I have IBS and I never heard of the leaky gut so that worries me and is something I will discuss with my doctor because I have been having a lot of difficulties lately. Thanks for this article it came at the perfect time.

    Stefanie Taylor · 08/11/2017 at 5:43 pm

    Hi Melissa, I am glad you found this article interesting and helpful. I know what you mean about IBS as I have suffered from it for a long time. It is such a hard thing to deal with and every body is different. It is one of the main reasons I researched in depth this subject as I wanted to help myself. The problem with this ‘leaky gut syndrome’ is that even though there is lots of information and research about it now coming in from all angles, many doctors don’t know or have official guidelines of how to treat it or even understand it (this is what I am led to believe anyway), so they may not be too helpful to you.

    I have actually found that since going vegan, which I have been for 9 months, it has virtually cleared up my IBS, so in my mind I can only think that eating animal hormones, which would have put my own hormones out of balance may have vastly contributed to it. As for your sleep, you should probably ask your doctor first before taking these supplements, especially if you have epilepsy as there may be contraindications. But if not, then go ahead and try them, they may help you all round with all of your issues. Good luck and I would love to know how you get on.

Is there a difference between taking L-Glutamine in a protein powder supplement to build muscle and taking it in a capsule? I was amazed to see how much work this one amino acid did. I’ve heard of it before but its not often that you get a full picture of all the functions L-Glutamine actually does in the body. Are there foods that you would recommend as well?

    Stefanie Taylor · 11/11/2017 at 3:57 am

    Hi there, yes L- Glutamine is a great little amino acid. I am taking it myself in powder from at the moment and it has really made a difference to my IBS. As for which form to take, it it probably depends on really what you prefer, the powder has a taste to it, which isn’t unpleasant but kind of lingers in your mouth. As with everything, always make sure you but from reputable brands, otherwise you may end up with a product full of fillers and preservatives. Yuck!

    There are lots of recommendations for diet, especially if you are eating for a fitness regime or just general healthy eating. My rule of thumb is always eat whole foods i.e. wholegrains, fruits, vegetables, pulses, nuts, seeds, lean meat (if you are not a veggie like me) and try to eat most veggies, fruits, nuts and seeds in as raw a state as possible to be sure you don’t damage all those nutrients and live enzymes.

Hi Stephanie,

So L-Glucomine helps with all things gut? Well, I drink too much tea and sometimes I feel it, its not nice, as it tends to make me feel bloated and get back acid – and of course from foods.

Not enough veg in my diet for sure. You think this L Glutamine will help? Oh, if I am anything like my parents, I am going to have arthitis for sure.

I have been looking for some kind of supplement that is not a fad but actually is going to be some good to be going forward.

Thanks Stephanie, this was helpful.

~Philip.

    Stefanie Taylor · 20/10/2018 at 11:20 pm

    Hi Philip, I think arthritis is hereditary so you probably should err on the side of caution and take some kind of preventative measures towards it. If nothing else you should eat a highly alkaline diet like explained in the post, and probably would be good for you to also use lots of turmeric. I have both my parents (who are prone to arthritis) on my homemade turmeric paste and so far they feel great. You should get your parents on it too!

Anson · 21/10/2018 at 6:30 am

Interesting article right there, learned something new today! Although I just started to get into gym-related stuffs, would definitely give it a go one day!

    Stefanie Taylor · 21/10/2018 at 10:36 am

    Hey there, that’s great! And yes, as you become more accustomed to the gym and getting fit you will more than likely start looking into extra nutritional support as your body often needs it under these circumstances.

fintan duggan · 21/10/2018 at 9:01 am

Hi Stephanie,
Thanks for all the information on l-glutamine, I had no idea that it is so beneficial for many health conditions,. I’m a big believer in plant based diets as well as regular exercise.
Do you think L-glutamine would be helpful for crohn’s disease?

    Stefanie Taylor · 21/10/2018 at 10:35 am

    Hi Fintan, now that’s an interesting question about Crohn’s disease and it seems totally feasible that it would, so I did a little more indepth research for you and it seems to be something that could definitely be beneficial. It makes sense really as l-glutamine help maintain the integrity of the intestine lining and also helps to lower inflammation. As these are both problems associated with Crohn’s then it is definitely worth a try – under consultation of your doctor first of course.

Dan · 21/10/2018 at 5:13 pm

Hi Stefanie,

Excellent article. Although I know that glutamine is important and I have taken it in the past, I have fallen off with taking it over the past few years. After reading this article I definitely want to incorporate it back into my daily supplements. I learned a few things in this article that I actually didn’t know about glutamine before. Thank you!

    Stefanie Taylor · 21/10/2018 at 7:15 pm

    Hi Dan, yes I’m like that with my supplements; I come and go off and on different things to find what works for me etc. But L-Glutamine is definitely one of those ones that I feel better with when I’m on them. I guess the thing is you can’t take them all as that would be overkill so you need to work out what is working, and what you should and shouldn’t bother taking.

    As I do a lot of gym work and I am vegan I feel better when I supplement with amino acids, and I’m pretty sure my body needs them.

Rob · 22/10/2018 at 12:55 am

L-Glutamine could be just the thing I’m looking for. I need something to reduce belly fat and give me energy. I just started a plant based diet too. I have type 2 diabetes and wondering if L-Glutamine will help with diabetes too? I’m exercising with the bike and walking to help shed the pounds and reduce the belly fat but also reduce the sugar cravings. Will this help reduce those cravings?

    Stefanie Taylor · 22/10/2018 at 4:09 pm

    Hi Rob, I’m glad you have started a plant based diet, you may f8nd the rest of my website helpful if you are a beginner as that is who I aim at.
    As for l-glutamine and blood sugar, I guess in theory it could as it helps to heal the gut which will help stop leaky gut syndrome and thus stabilise your blood sugars. So it can only help. Would probably depend if you do have but issues already, which you yourself would know. For instance, if you’re prone to long term IBS rhen this may well have compromised your gut lining.

    Stefanie Taylor · 23/10/2018 at 9:33 am

    Hi Rob, I’m sorry to hear you have diabetes but glad you are finding ways to help heal yourself. They say that they type 2 diabetes can be controlled, even healed through diet alone, so the plant based diet is a great place to start with that. You will find lots of information about this kind of diet on my website if ever you get stuck or have any questions.

    I suppose in a round about way L-Glutamine could potentially help with blood sugar due to the fact that it helps to heal a a leaky gut which is often caused by IBS. Therefore, if you have gut problems then this could be throwing your blood sugar out of wack too!

Holly · 24/10/2018 at 1:38 pm

I am one of those unfortunate ones that had been given entirely too many antibiotics over the years for various ailments going on, before I was able to take back control and go the natural route. So thankful I did that.

L-Glutamine became one of the few supplements, along with bone broth, that really made a big difference. Leaky Gut is real and it affects people more than they realize.

    Stefanie Taylor · 24/10/2018 at 8:37 pm

    Hi Holly, oh no, yes antibiotics can really mess with your gut flora and gut lining. Personally, I have not had that many antibiotics in my life but I’m pretty I had leaky gut due to the fact that I had really bad IBS before I went plant based, this carried on for many years due to stress and really messed my gut up. Now thankfully, since my change of diet and use of L-Glutamine I am finally healing.

    I,m glad you have healed your own problems and yes, I have read in countless research articles that so many people have undiagnosed leaky gut that is causing all sorts of problems for their heath.The thing is most conventional doctors still don’t recognise it as a real thing. Crazy!
