Best Glutamine Powders
Amino acids. They are one of the most important protein building blocks in our bodies. And while, yes, it is true that these supplements are naturally present in our bodies and can also be obtained by certain foods, with an intense workout regime, our bodies need more. Glutamine Powder specifically is an important amino acid to replenish after a demanding workout because it has been shown to lessen your muscle breakdown, therefore accelerating your recovery. It is also important to our digestive tract and overall immune systems. If you have had or been on the verge of leaky gut, it is likely that your doctor recommended this supplement. Deciding which product and dosage will fit your lifestyle can make for a tiring day of research. We invite you to sit back and relax- you will find the answers to those questions and more in this guide.

OUR TOP PICKS FOR THE BEST GLUTAMINE POWDERS
1. EVLUTION NUTRITION
It comes with a scoop
It is sourced from high-quality plants
You receive five grams per serving
The “flavor” is not very good
Truth be told, there really are numerous fantastic options on the market and a lot of them are very similar in quality. When it comes down to it, though, Evlution Nutrition stands above the rest.Read more
As you will see, several options on the market offer 5000 milligrams (or five grams) of L-glutamine per serving and this is one of them.
First off, it is noted that this formula is sourced from high-quality and easy-to-metabolize plant sources. Secondly, this is free of gluten and has been made in a GMP-certified facility.
The good news is this dissolves quickly and efficiently in most drinks. However, though this is unflavored, the taste is still a bit noticeable.
There are two different size options at your disposal. You have the option for 60 servings (which is the 300-gram bottle) or 100 servings (which is the 500-gram bottle).
This is a great deal! Not only is this product effective but it is also one of the most affordable on our list. In addition to the scoop that is included with your purchase, the container itself is sized very well to offer you convenience.
If you are looking for an option that excels in purity, potency, and value then look no further. Evlution Nutrition deserves a ton of credit for this one.
2. KAGED MUSCLE
The packaging is superb
It is banned-substance free
It is an all-vegan formula
The powder does not dissolve the best
Just based on the product description, you can tell that Kaged Muscle takes a lot of pride in the supplement that they have produced. Let’s just say that every ounce of it is justified.Read more
To help quickly replenish your glutamine levels, there are five grams of the amino acid in every serving of this formula.
To avoid any issues if you are a vegetarian, this formula has been made using plant-based raw materials. In addition to this, it is also third-party tested and also banned substance-free for ultimate purity.
As you will notice when you try this, there is a bit of chalkiness to the flavor and texture. Speaking of texture, this stuff does not dissolve that well in liquids.
If you just wanted to sample this stuff, you could buy the 60-serving bottle instead of the 100-serving one. Either way, the option to pick between them is nice to have.
Another affordable product here. With the 300 gram option, you are paying $1.28 per ounce. With the 500 gram option, you are paying $1.14 per ounce. As a bit of a bonus, a long scooper is included with your purchase to make it easier to obtain the powder itself. As for the container, it is sealed and well-designed.
Admittedly, the taste and texture could be better here but you could say that about virtually every other glutamine powder on the market. It is just something you need to contend with as the purity and potency of this formula are top-notch.
3. BPI SPORTS
8 grams per serving
Available in four different flavors
The packaging could be improved
Some have complained of an unpleasant aftertaste
Almost every reviewer has been impressed by the quick and noticeable results that they have experienced after adding this supplement to their routine. It is available in four surprisingly delicious flavors and packs 8 grams per serving!Read more
This supplement from BPI really packs a punch! It is made up of six different types of glutamine. In each serving, you’ll receive 8g of the supplement which is very high and effective! Almost all reviewers have experienced faster healing times and noticeable results.
On the ingredients list, you’ll find everything that you expect, plus the addition of other natural and artificial ingredients, such as sucralose, silica, and potassium hydroxide. This was a turn off for some customers.
This blend is available in four different flavors. You have the choice of 4 berry citrus, lime sherbert, peach mango, or snow cone. You simply mix one scoop with six ounces of cold water. We are pleased to report that reviewers are thoroughly impressed by the favor and actually look forward to drinking it. However, there have been a few reviewers who claim that it tastes good going down but has a bad aftertaste.
This product is available in only one size, 14.1-ounces.
The price per container depends on which flavor you choose. There is not a large price difference between the four options. On average, the product costs about $1.64 per ounce. This is one of the more affordable options on our list and it contains fifty servings per container.
There are not many negative remarks about this supplement from BPI Sports. We love the choice of flavors and the intense potency of the product. More sizing options would be nice, but now we are just nitpicking.
4. NAKED GLUTAMINE
You get five grams per serving
It is third-party tested
It absorbs pretty well in water
The packaging needs to be improved
Even though the packaging could stand to be improved, it is tough to argue with the formula that has been implemented here. It is just top-notch in every sense of the word.Read more
One scoop of this powder (which accounts for one serving) will provide you with five grams of this amino acid.
To take comfort in knowing this is as pure as it gets, it is a pharmaceutical-grade supplement, has been made free of sweeteners, colors, flavors, and fillers, and is third-party tested for value, safety, and purity.
It is arguable but this could be one of the better options in regard to the flavor and texture. The best part about the flavor is you can barely taste it (which is the point) and the substance absorbs well into the water.
Due to the fact that this container comes with 1000 grams of powder (which works out to 200 servings), you can’t really sample it to see if you like it.
Buying in bulk is always a money-saver. This 2.2-pound package works out to only cost you .99 cents per serving. However, if you are picky about the packaging and accessories, the included clear scoop gets lost inside the container and, secondly, the lid can be more difficult to unscrew than it needs to be.
You can make the argument that this right here is the best option on the market and few people would disagree with you. If the packaging was a little better, perhaps we would feel so too.
5. OPTIMUM NUTRITION
There are four different sizes available
The product purity is exceptional
The serving size is high
The texture and flavor are not the best
If you know anything about supplements such as these then you probably have heard of the brand Optimum Nutrition. They have earned the trust of thousands of consumers around the world due to products like this.Read more
As with the other top-end options on the market, five grams of this amino acid are provided for you with each serving of this formula.
Optimum Nutrition produces and packages their powders in their own state-of-the-art manufacturing facility. This same facility has been registered under the NSF International, Good Manufacturing Practices Program, and The Public Health and Safety Company.
Even though this is marketed as being unflavored, various buyers have noted that a flavor can, in fact, still be tasted (and it is not pleasant). Also, the texture will get gritty if you do not drink it quickly enough.
For your convenience, there are four different sizes available that you can choose from. Among them, you have 150, 300, 600, and 1000 grams.
The value of this product depends on the size you order. From 300 to 600 to 1,000-grams, the price per ounce differs from $1.67 to $1.41 to $1.14 per ounce. If it is important to you, the container that holds the substance is properly sealed but it is also on the skinny side (which makes retrieving the powder a bit more annoying than it needs to be).
Well, would you look at that? Here is another brilliant option that just so happens to have an uneasy flavor. Of course, the multiple size options are a nice subtle bonus.
6. MP ESSENTIALS
There are two different size options
The formula is banned-substance tested
You receive an optimal 5000 milligrams per serving
Again, this is another option with a bad taste
At this point, you should begin to get an understanding that there really are several options worth buying on the market. This option is just another superb one on a long list of them.Read more
There is nothing too shocking here as this formula provides you with five grams of L-glutamine.
This is certified by Informed-Choice and that means that it has been banned-substance tested. This attributes to a purer product that you will be consuming.
The good news is this tends to mix quite well with water and other liquids (though a slight grittiness will still be noticed) but it also does not exactly taste good.
Whether you want 300 or 600 grams (which works out to 60 and 120 servings, respectively), you can choose between either one.
With 300g and 120 servings per container, the price per ounce of this product is just $1.11. The combination of the well-designed lid and the wider body is ideal and not too many of you will have too many complaints in regard to the packaging here.
With options like this, it becomes more difficult to choose as it shows how close and fierce the competition is for glutamine powders. Granted you can contend with poor flavor, this is highly recommended.
Each batch is third-party tested
Two size options are available
This is gluten-free and suitable for vegetarians
The taste is not very pleasant
It is funny; a majority of these powders are marketed to be “unflavored”. Yet, most of the time (including here), you can notice a taste and it is typically not very good.Read more
Once again, you receive 5000 milligrams of unflavored glutamine per serving with this supplement.
Count on this being pure as every single batch that is ever made is HPLC tested beforehand. Oh yeah, and this also has been tested by independent third-party labs to ensure product purity even further.
As was alluded to, this is an unflavored option but it certainly gives off some sort of flavor. Most users agree that the taste is strange and almost indescribable.
If 500 grams is not going to cut it for you, you can opt for the option that provides you with 1000 grams of this amino acid. For the record, the former has 100 servings while the latter has 200 servings.
With the 500 gram package, you pay $1.14 per ounce. There is also a 1,000-gram option that would save you even more! As far as the packaging goes, it seems to be fine but one buyer reported when they opened up the container, a small insect flew out. Thankfully, this has not been a common occurrence.
Truth be told, this formula does not reinvent the wheel but if it is not broke then why fix it, right? No matter how you want to look at it, this is another really good option regardless.
8. NOW SPORTS
Quite a few buyers have noted that it mixes well in water
It has been tested for banned substances
You get five grams per serving
The container is not designed very well
NOW Sports is yet another top-quality brand that you can place your trust in. However, one thing to note, the container that this is packaged in is not the best as it is not very user-friendly.Read more
You guessed it; this is yet another option that provides you with five grams of this amino acid per every serving you take.
This has been tested for banned substances by LGC and it has an Informed-Sport seal to prove it.
Quite a few buyers have noted that this mixes very well with water. However, though no artificial flavors are added, a few users have claimed that this has a somewhat sweet taste.
This container provides you with 91 servings and comes with one pound of powder (which works out to around 454 grams).
As with most NOW products, this one is also quite affordable. This supplement ends up costing you $1.11 per ounce. When you get down to the nitty-gritty, it can become difficult to retrieve the remains of the powder as this container is tall and skinny (for whatever reason).
In theory, you could always transfer this from the included container to another airtight container. Doing so would get rid of the main issue with this option, which is saying something.
9. BODY FORTRESS
It is free of sugar, milk, wheat, and gluten
There are 4500 milligrams per serving
Conforms to USP/NF requirements
It does not come with a scoop
Again, the taste is not very pleasant
Because this option is offered in such a small container, it may not be the best for those of you who are looking to buy in bulk. Then again, the formula is both pure and potent so that is nice.Read more
The potency is right up there with the best as 4500 milligrams of this amino acid is delivered per serving here.
In spite of the fact that this batch is not NSF certified or USP verified, it does conform to the USP/NF requirements. For the record, these requirements are industry-standard for both testing and purity purposes.
There have been a number of previous users who have commented negatively about the taste of this supplement. It just seems a bit odd and is not flavorless.
This comes in a 300-gram container and, all things considered, is not bad but not ideal for those of you who want to buy in bulk (unless you plan to buy multiple containers).
Talk about a deal! This is the cheapest option on our list. At 10.6 ounces total and a low price point, each ounce of this supplement costs you only .93 cents. Even though it is not an astronomical deal, it sure would have been nice if a scoop was included with your purchase. Instead, you will need to account for it yourself.
Sometimes, it is the little things that matter. While this is a fantastic formula, the lack of a scoop and the smaller size may be off-putting to you.
10. BULK SUPPLEMENTS
You can buy this in bulk
The taste is barely noticeable
It has been lab-tested for purity
The packaging needs to be improved
The serving size is pretty small
To say this option is a fan-favorite is a vast understatement. But, what you need to understand is the serving size (one gram) is significantly smaller than other options on the market.Read more
Indeed, the potency is less than you will be used to here (if you go with five-gram-per-serving options). Per serving, you are provided with only 1000 milligrams of L-glutamine.
Past the fact that this is non-GMO, it has been lab-tested for purity and verification. Just know that what you are putting into your body is not contaminated.
For the most part, it seems this lacks taste at all (which can be seen as a positive). However, a number of reviewers have noted it does smell a bit.
Talk about buying in bulk? The 25-kilogram option provides you with an astonishing 25,000 servings (though much smaller options are available).
As with most products, the bigger the package you buy, the cheaper this supplement is. With so many different sizing options, the price per ounce ranges from $3.39 to .55 cents. For many consumers, the biggest issue with this supplement is packaging. It is not a container and instead is a resealable pouch. The main problem comes with the resealable strip as it is not well-designed.
Some improvements could be made here; yes, but the purity and the fact that you can buy this in a 25-kilogram option may be enough to sell some of you.
Criteria Used for Evaluation
Based on the serving size, you can assess the potency of any one option.
It was briefly discussed at the beginning of this guide but it is worth looking at closer; why exactly do you need to take glutamine supplements when the amino acid is naturally produced in your body? Well, in the simplest of explanations, the majority of this amino acid in your body is manufactured in your muscle cells (to keep your muscles functioning normally). This is why under stressful conditions (such as during injury or intense workouts) it is recommended to supplement glutamine as it tends to be used up very quickly by your body. Now, moving forward, when it comes to finding the right supplement on the market, first address the serving size.
For the most part, you should aim for options that provide anywhere from three to five grams (or 3000 to 5000 milligrams) of the amino acid per serving. As you noticed on this list, most models will offer closer to five. Of course, how much of this stuff do you need to supplement on a daily basis, anyway? While various factors will come into play, most of you will probably want to strive for 20 to 30 grams daily. Again, though, if your body is not using up that much of the amino acid, you may not have to take it to this extent.
It goes without saying that this section is about as critical as it gets.
Now that you got the potency you need out of the way, it is time to talk about something incredibly critical. Under no circumstance should you bypass this section as product purity is substantial in this case. The question then becomes, how do you tell if a certain option is pure? For starters, you need to know what type of facility was used to process and package it. In general, the facility needs to have some sort of certification. A common one is GMP (Good Manufacturing Practice) as this is a system that is used to ensure that products are consistently produced to quality standards (especially when it comes to pharmaceutical production).
In addition, looking for formulas that have been third-party tested is recommended. In short, if a supplement has third-party certification, it means it has been reviewed by an independent organization and complies with specific standards set out for performance, quality, and safety. Oh, and another thing, let’s talk about banned-substance testing. You will often see options with an Informed-Choice certificate and it basically means that the specific formula has been tested for banned substances by LGC’s anti-doping lab. Also, one last thing, if you prefer vegan-friendly supplements then look for formulas that have been sourced from high-quality plants.
Not only is this about the taste but it is also about the texture (both are vital).
Let’s just say that glutamine powders are not produced to taste like soda pop or chocolate milk. But, at the same time, you should not be forced to gag down your mixed supplement. The reality is if you go with a powdered option, this problem is going to face you. Now, ironically, there are several options on the market that are unflavored. However, the ironic aspect comes into play when you realize that most of these same formulas do have flavor and it is typically not very good. The thing to do, really, is to look through user feedback to see what others have had to say about the flavor.
Of course, what are you supposed to mix this stuff with, anyway? Well, it can safely be taken with or without meals but when it comes to liquids, you need to avoid highly acidic and hot beverages. The reason for this is both of these types of drinks will degrade the glutamate and subsequently diminish the benefits of it. Oh, and as for the texture, you really just want to make sure that the powder itself can mix well with your liquid of choice. If not, you may be left with a gritty and clunky mess; and who really wants that?
Variety is the spice of life and keep that in mind for this section.
So, this one is easy, right? The larger the bottle, the better, right? Well, not so fast as this deserves a much closer look. Now, to start, let’s clarify that there is not one correct capacity option and really what you want is variety. There are both positives and negatives to containers that are bigger and smaller. On the one hand, it is nice to buy a smaller container if you want to test the waters, so to speak. But, if you already know a brand works for you, having the ability to order a larger container may work better for you. In general, options on the market can range anywhere from 200 to 2000 to 300 to 1000 grams (it varies quite a bit from a seller to seller).
The value of an item is something that should never be overlooked. To take value into consideration, you can assess the servings per container, serving size, and cost. There may be two options that have the same grams of supplement, but one is half the price of the other. Without determining the value of the products, you may be inclined to purchase the less expensive of the two. However, chances are that the cheaper product is less potent. Therefore, the larger and more expensive product ends up being much more cost-efficient. If you were simply looking to get the best value, look for the cheapest option with high potency and plenty of servings. In other words, you can’t just look at the price. It is also always helpful to check out if the manufacturer offers a guarantee of any sort. For a lot of people, finding the right supplement can be a headache and by the time you have found what works for you, your supplements cabinet is filled to the brim. There are some reputable brands out there that will receive returns if the product does not live up to your expectations.
Expert Interviews & Opinions
You may be wondering why we prefer to take this supplement in powder form rather than pills. The fact is that the daily dose is quite high and to get this full dosage, you would end up taking an uncomfortable amount of capsules. This can be upwards to fifteen pills per dose, meaning more than once a day. Additionally, and perhaps more importantly, powder is much easier for the body to quickly absorb.
As important as the potency is, you can easily make the argument that this is more important. And, there is actually quite a bit that goes into determining if a specific option is “pure”. In addition to looking for batches that are processed and produced in state-of-the-art facilities that are certified by health-conscious companies and systems, also look for third-party certifications and banned-substance tested formulas.
Would it not be nice if this type of powder tasted like cotton candy? Of course, this is fantasy-land stuff as this is just simply not going to be the case. Instead of setting your standards too high, simply look for options that you can get down without gagging or puking. Most options will actually be flavorless and if you mix them correctly, it will not be too terrible to get down. Oh, and do not forget about the texture.
Other Factors to Consider
You may be thinking, "What? Durability. This is a powder." You are right. In this section, we are less focused on the supplement itself and more focused on the packaging. Don't you hate it when you receive a damaged container? Or a packet that is nearly impossible to reseal? It happens, and that is why the packaging is an important feature to look at before investing.
To begin, two of the most common packaging options that sellers use are traditional containers and pouches. It seems that most of the top-end options utilize containers but you will see pouches from time to time. The benefit of containers is they can be sealed with an accompanying lid. Yet, you need to ensure that the seal is present and well-designed.
Also, in regard to containers, if they are too skinny it can be very difficult to retrieve the powder once you get down to the nitty-gritty. As for pouches, if they are resealable, you may want to make sure that the seal works. In theory, though, you could always transfer the powder from the included package to one that you prefer. Just ensure that whatever you store it in has an airtight seal for maximum freshness. Oh, and one last thing, you may want to look for options that provide you with a scoop as this can make it easier to achieve proper serving sizes.
Frequently Asked Questions
q: Who can benefit from this supplement?
It has been alluded to a few times already but just so you have a keen understanding of who this stuff works best for, let’s take a closer look. To start, if you currently have a muscle tissue that is in the state of healing or repair (from either some sort of illness or injury) then it may be a good idea to supplement this amino acid. The same goes for when you are partaking in periods of intense exercising. Of course, do remember that this type of supplement is not exactly designed to be a solution for digestive issues.
q: Can I take this alongside other supplements?
Though you may be worried about combining this with other supplements and meals, it can actually be beneficial to do so. However, which are some of them that you can combine the amino acid with? Well, for starters, how about sodium? What is really interesting is glutamine transport occurs via a mechanism that is dependent on sodium. So, with the combination of sodium, the supplement can be more effective. Oh, and you can also use it with BCAA supplements as this can lead to gains in muscle performance and mass.
q: Is it bad for your liver?
Due to the fact that previous studies have shown that supplementing with this amino acid can improve the health of your liver and even be used as a treatment in the early stage of liver cirrhosis, you would think the answer to this question would be easy to answer. However, if you do suffer from liver cirrhosis (or even have a risk of it due to your family’s history) taking large amounts of glutamine can actually have ill effects.
q: How much should you take?
This is another question that was alluded to earlier. But, it is so commonly asked that it deserves closer inspection. Here is the deal; there is no one correct answer when it comes to how much of this supplement you should be taking daily. Some “expert” websites will advise taking between 10 to 15 grams per day. Of course, you will also see upward of 30 grams advised per day. But, as was mentioned earlier, it really comes down to how much your body needs it (which depends on factors previously documented).
q: Can it make you gain weight?
Not only is this stuff not going to make you gain weight but it can also help to reduce weight and here is how. Basically, when you supplement glutamine you can reduce the food cravings your body has. And, this becomes important if you are already overweight as your body needs even more of the amino acid than normal.
q: When is the best time of the day to take it?
The most common times you will hear many fitness enthusiasts and experts claim to take this supplement are right when you wake up, right when you go to sleep, and also roughly 30 minutes before or after exercising. Without going into extraordinary detail, do you want the good news? If you are a fan of scientific studies and reference them when it comes to proving something, then you can take comfort in knowing that all three times have been backed up by previous studies in the past. So, you can choose the best time for you and your needs.
