scoop of the best glutamine supplement recommended by a nutritionist

This is our review of the best glutamine supplement in . 

It’s fantastic to see more and more people invested in building their health, fitness and stamina. However, it is common for people to feel fagged out and sore for days after a strenuous workout. This is where supplements come in. 

It is, of course, recommended to follow a healthy diet that keeps pace with your fitness schedule. Still, the right supplement can genuinely complement the work done by your food regime.

My clients often ask me about the best way in which they could overcome muscle soreness and hit the gym for the next workout. While I recommend supplements based on individual goals and health status, I have a fail-safe that works with most people – glutamine.

Glutamine is probably one of the most important amino acids because it contributes heavily to tissue repair, gut health and immune strengthening. 

As a supplement, this tiny amino acid in the right amount will help you go the extra mile – quite literally! The best glutamine supplement is the one that helps your muscles recover faster and strengthens your gut for a healthier digestive experience and a flatter belly. KAGED MUSCLE, L-Glutamine Powder fits the bill perfectly for this!

But yes, I hear you. Each of you has different fitness goals. And so, I have compiled a list of the 9 best l-glutamine supplements on the market today.

A Quick Guide to the 9 Best Glutamine Supplements

Note: All nutritional facts mentioned below are for a single serving as mentioned on the product label.

KAGED MUSCLE L-Glutamine Powder – Best Glutamine Supplement (Overall)

Total L-Glutamine (fermented) = 5g

What I love most about KAGED MUSCLE L-Glutamine Powder is that it delivers absolutely pure L-glutamine that has been derived through a plant-based fermentation process and is not synthetically manufactured. This translates into better absorption of glutamine in the gut. 

The cherry on the cake is that this product is third-party tested and has been certified as banned substances-free.

What The Formulation Means For You

This supplement provides a good dose of glutamine per serving. The higher the quality of L-glutamine in the supplement, the quicker it will be absorbed by the body. And so, the muscles will recover faster from particularly strenuous workouts. This is because glutamine will help bring down the lactic acid buildup in the muscles that bring on the typical soreness.

Go for this supplement especially if you are into intense workouts or have a demanding athletic performance coming up. This one is my top pick in glutamine supplements.

Customer Reviews:

KAGED MUSCLE, L-Glutamine Powder is a favourite with most customers who vouch for its muscle recovery creds. It has also been recommended highly because it stacks well with other supplements.

NOW Sports Nutrition L-Glutamine Pure Powder – Best Glutamine Supplement (Budget)

Total L-Glutamine (free-form) = 5g

Another great product in the market of L-Glutamine supplements is NOW Sports Nutrition L-Glutamine Pure Powder. It should be the go-to for anyone who has one eye on the budget.

It offers non-GMO, vegan and kosher glutamine as a free-form glutamine powder. Any nutrient present in free-form increases its bioavailability, which means the body can absorb it better and more quickly. They also test each batch for strength and safety.

What The Formulation Means For You

Because glutamine is present in its pure form, this product does well in helping you recover from muscle soreness by reducing the lactic acid buildup. It also serves as a nitrogen transporter in the body to help maintain nitrogen balance, again playing a role in muscle recovery.

Customer Reviews:

Many people endorsed NOW Sports Nutrition, L-Glutamine Pure Powder more for its mood-enhancing and gut-healing properties, along with its muscle recovery capabilities. However, a few people recommend starting with lower dosages and slowly increasing to full dosage to prevent any digestive upsets.

Forzagen BCAA Powder with Glutamine – Best Glutamine Supplement for Muscle Recovery

Total L-Glutamine: 2g

If you want a glutamine supplement that can be consumed pre, intra or post-workout, I will direct you to Forzagen BCAA Powder with Glutamine. It has a 2:1:1 recommended BCAA formula and a decent hydration complex that allows you to train harder and hydrate as you work out.

What The Formulation Means For You

The combination of Glutamine and BCAA means faster and better muscle recovery than seen with isolated glutamine supplements, along with an increase in endurance and muscle building.

This l-glutamine supplement is suitable for those people who like to keep the number of individual supplement products to a minimum.

A word of caution though. This product has artificial flavours and fillers. So if you are looking for a product that is essentially pure, then this one is not for you.

Customer Reviews:

Most customers are happy with their energy levels since starting Forzagen BCAA Powder with Glutamine. However, a few people did not like its taste. They found the flavours overly sweet and ‘chemical-tasting’.

What I liked best about this product was that it has no unnecessary fillers and no artificial flavoring. This automatically ranks it high on my health radar.

What The Formulation Means For You

In addition to having Glutamine and BCAA, which help in muscle recovery and maintenance, BodyTech BCAA+Glutamine has a surprise ingredient: Vitamin C! Those wondering why they would include this vitamin in a workout supplement, Vitamin C is one of the finest natural antioxidants we know. This means that cell damage because of intense workouts can be reduced because of its presence.

The most significant advantage is that this product helps you get used to glutamine supplementation gradually and lets you increase the dosage as your tolerance goes up.

The l-glutamine in this product is naturally fermented using vegetable sources, making it my top pick in vegan formulations.

What The Formulation Means For You

Since l-glutamine is available in free form in this product, its absorptive capacity is much higher than most products. This makes it my favourite choice for vegans who cannot supplement adequate glutamine from their diet.

Customer Reviews:

What is Glutamine?

Glutamine is one of the most important amino acids needed by human beings. It is a conditional amino acid, which means that it can be produced by the body in limited quantities and the rest needs to be obtained from the diet.

Glutamine is an important building block for proteins and is also required to produce other amino acids.

What are the types of Glutamine?

Glutamine exists in two forms: D-Glutamine or just Glutamine, and L-Glutamine.

The difference between these two forms in the arrangement of atoms within the glutamine molecule. L-Glutamine is the form that is majorly produced by the body and found in the diet.

L-Glutamine has a variant in the form N-acetyl Glutamine, which some research studies say has more efficient gut-healing properties.

What are the benefits of Glutamine?

Glutamine is the most abundantly found amino acid in the body and has numerous benefits. 

Muscle recovery

Glutamine helps to reduce muscle soreness and hasten muscle recovery by reducing lactic acid buildup, which usually happens when you exercise or work out.

Immune enhancer

Glutamine is an important building block for proteins in the body, including the production of white blood cells, which help the body fight disease. This is why glutamine supplementation is advised to many people recovering from a major illness or injury.

Gut healer

Glutamine helps to maintain the integrity of the inner barrier layers of the intestines, thus preventing bacteria and harmful germs from trespassing into the body.

Post-trauma recovery

Some studies have shown that glutamine supplementation helps in faster healing of deep wounds that are usually seen after burns, a critical illness or surgery [1].

What are the side effects of glutamine?

Side effects from glutamine supplementation are very rare, especially if taken in its recommended dosage.

If they do happen, they are usually mild and include nausea, bloating, heartburn and dizziness. However, regular excess consumption of glutamine may cause liver damage and blood in the urine.

A word of caution: People with liver or kidney problems must consult a doctor before starting a glutamine supplement.

What foods are high in glutamine?

Glutamine is an amino acid that plays a vital role in maintaining health. It is found in many foods. However, animal foods are better sources of glutamine than plant-based foods.

Animal sources of glutamine:

  • Meat
  • Organ meat
  • Seafood
  • Milk
  • Eggs
  • Bone broth
  • Yogurt

Plant sources of glutamine:

  • Nuts
  • Cabbage
  • Beans
  • Dark leafy greens
  • Asparagus
  • Legumes

How much glutamine should I be taking?

The recommended intake of glutamine is 3 to 6 g per day [2], although athletes have been known to take higher doses depending on their individual requirements and under professional supervision.

Buying guide: How To Choose the Best Glutamine Supplement?

Look out for the below points when buying a l-glutamine supplement.

Check ingredients

The purer the glutamine, the more efficient are its results. Always look for sources of ingredients and their nature (non-GMO, hypoallergenic, certified pure). Go for products that mention “free-form” or “fermented form” of the nutrient. Also, based on your individual preferences, look for vegan and kosher tags.

Supplement delivery form

Glutamine supplements are available in powder and capsule form. Go for the form you prefer personally and the one that works best for you.

Cost

Budget is a major factor for most people, and rightly so. So choose a supplement that gives you the nutrition you want in the budget you are standing by.

Final Words

Glutamine supplementation is a versatile field. Its benefits are not restricted to muscle recovery and exercise performance. Glutamine has a wide-ranging array of benefits, from intestinal health to immune enhancement and wound healing. KAGED MUSCLE L-Glutamine Powder checks all of these boxes for me, though I would highly recommend you to go through our entire list to find your perfect fit.

FAQs

Is glutamine a BCAA?

No, glutamine is not a part of the BCAA trio. It is a conditional amino acid that is abundantly found in the human body.

Can glutamine help me build muscle?

Not directly. Glutamine is more of a post-workout recovery supplement. When muscles are able to recover faster, you can train regularly. This will help to build muscle.

You can take a pre-workout supplement without beta-alanine to maximize your workout sessions and in-turn see the best results.

Is glutamine useful for weight loss?

Glutamine doesn’t have any direct implication on weight loss. However, glutamine is a wonderful gut healer. It helps to enhance the absorption of nutrients in the gut and reduces gut disturbances like bloating and constipation. This can help you get a flatter belly.

A combination of an active lifestyle and a healthy diet is the easiest way to lose weight. You can use a magnetic resistance spin bike to help you create the calorie deficit to see sustainable weight loss.

What does glutamine do for your workout?

When you work out, muscles become sore because of lactic acid buildup. Glutamine helps recover the integrity of muscles by helping lactic acid get absorbed faster into the blood.

Why do we need glutamine supplements? 

Even though glutamine is abundantly present in the body, its requirement goes up phenomenally when the body is in a state of anxiety or in cases of physical stress, such as after an illness, injury and after an intense workout. Also, because animal food sources contain reasonably good amounts of glutamine as opposed to plant-based sources, vegetarians and vegans may fall back on their glutamine requirements. For these reasons, we require glutamine supplements. 

What do ‘free-form’ and ‘fermented’ glutamine mean?

When a nutrition table mentions the presence of ‘free-form glutamine’, this means that the amino acid is available without being bound to other amino acids or proteins.

‘Fermented glutamine’ is when the amino acid is derived through the natural process of fermentation of plant-based sources. 

Both free-form and fermented varieties of glutamine allow the gut to absorb them better than regular glutamine, making them highly bioavailable. Thus maximising their benefits.
