A list of the best glutamine supplements on the market


Last Updated on

Are you supplementing L-Glutamine? If not, maybe you should consider it after reading the following benefits. Glutamine is a carbon and nitrogen donor and helps restore glycogen which restores energy. It is the most important component of muscle protein, and helps repair and build muscle. Glutamine is a critical amino acid for the immune system and for keeping the nitrogen levels in your body in check. Moreover, glutamine makes up to 60% of the free amino acids in the bones, making it a good supplement for body builders and gym enthusiasts. We’ve put together the ten best glutamine supplements on the market.

1MuscleTech Platinum Glutamine BEST OF THE BEST

MuscleTech uses a specialized processing technology to reduce the particle size of its glutamine powder so it is more readily absorbed and easier to blend into shakes and smoothies.

It’s tested for purity and efficacy with advanced chemical analysis equipment, so you know that each 5000 mg scoop is going to be pure glutamine.

2Optimum Nutrition Glutamine SECOND BEST

Optimum Nutrition’s glutamine capsules are the best choice if you want a capsule-based glutamine supplement. Each capsule has 1000 mg of glutamine in a gelatin capsule, with only magnesium stearate added to keep it shelf-stable.

For those seeking a moderate dosage, and for those who hate the taste of glutamine powder, it’s excellent. If you want to take several thousand milligrams of glutamine per day, it’s probably better to opt for a powder based supplement, and of course a strict vegetarian won’t go for a gelatin capsule. That aside, just about everyone else can be happy with this glutamine supplement.

3Evlution Glutamine THIRD BEST

Evlution’s glutamine formulation is 100% pure glutamine powder. There are zero other ingredients; no stabilizers, no binders, and no flavoring agents.

This might not be what you want if you don’t like the taste of glutamine, you might not be a fan of taking 5000 mg of glutamine powder with no flavoring, but for serious glutamine users, this is a great choice.

4BulkSupplements Pure Glutamine

BulkSupplements is king when it comes to huge quantities of highly pure supplements in powder form. If you know you’ll be going through a tremendous amount of glutamine, it should be your go-to choice.

The large bags can be a little unwieldy, and they aren’t the greatest when it comes to staying closed, but the quality of the product itself is unassailable.

5Pure Encapsulations Glutamine

Coming in a 1000 mg capsule, this is another good pill-based form of glutamine. Of the capsule form glutamine supplements that are vegetarian-friendly, this one is the best.

Pure Encapsulations use a cellulose capsule from plant material, plus ascorbyl palmitate as a preservative. Like other capsule supplements, it’s good if you dislike the taste and inconvenience of powder, but it’s not very practical for high doses on a regular basis.

6Kaged Muscle Glutamine

Kaged Muscle uses its trademark fermenting process to partially metabolize and active the glutamine in this supplement, which should lead to more effective absorption and better bioavailability.

With something taken in as high of a dose as glutamine, this may be less important than with other supplements, but it’s still a unique perk that you’ll only get with Kaged Muscle.

7MP Essentials Glutamine

Available on Amazon

MusclePharm produces a powdered glutamine supplement like many of its competitors, and the quality is good: no extraneous ingredients, and each scoop contains a hefty amount of glutamine.

The main drawback is the fact that this powder is produced on the same equipment as other supplements that might contain gluten, dairy, or eggs. This means it’s not the right choice if you have food sensitivities. Other competitors offer similar products that are certified free of allergens.

8BPI Sports 100% Pure Glutamine

Available on Amazon

Coming in powder form, this glutamine supplement delivers six different metabolized forms of glutamine, totalling 6500 mg of glutamine per ser scoop.

It also includes 500 mg of vitamin C for extra antioxidant and recovery power. The dosage and variety of glutamine is great, but purists won’t like the artificial flavors and coloring agents.

9Jarrow Formulas Glutamine

Jarrow Formulas offers a capsule-based glutamine supplement that’s vegetarian friendly and delivers 1000 mg of glutamine per capsule, but it can’t quite measure up to the purity of some of the other manufacturers that make glutamine pills. There are a few too many extraneous ingredients that other companies manage to get by without.

10Now Sports Glutamine Powder

Available on Amazon

Now Sports has a pretty standard glutamine supplement. It’s powder-based, has no extra ingredients, and comes in a 500 gram bottle, which is enough for 100 high-dose servings.

Now Sports doesn’t really distinguish itself with this supplement, and unfortunately its reputation is less than stellar with the quality of some of its other ingredients, so barring evidence to the contrary, it’s probably better to go with a competitor offering a similar product instead. Even so, there’s nothing objectively wrong with this supplement.
