Our “WOW Factor” Buyer’s Guide

A lot of people are asking about glutamine supplements and what they do.

It can be hard to know which supplements to take and whether they're worth the money.

We've got you covered. Our glutamine supplement is the best on the market and it's backed by science. Not only does this supplement help with muscle growth, but it also helps improve your immune system function and reduces recovery time after a workout.

Here are the most frequently asked questions about Glutamine Supplements and our answers to them.

What form of glutamine is best?

There are three main types of glutamine supplements on the market: L-glutamine, D-glutamine, and L-alanyl-L-glutamine. L-glutamine is the most common form and is generally considered the most effective.

However, some studies have shown that D-glutamine may be more effective in certain situations, such as muscle recovery after exercise.

L-alanyl-L-glutamine is a newer form of glutamine that has been shown to be more stable and absorbable than other forms.

So, if you're looking for the best form of glutamine, it really depends on your specific situation.

Which is better L-glutamine or glutamine?

There is no definitive answer to this question since it depends on each person's individual needs. Some people may find that L-glutamine works better for them, while others may prefer glutamine.

However, both of these amino acids can be beneficial for gut health, immune function, and muscle recovery. So, it really depends on what your specific goals are and which one works better for you personally.

Is a glutamine supplement worth it?

Glutamine is an amino acid that is produced by the body and found in high levels in meat and dairy products. As a supplement, it is used to increase muscle mass, improve exercise performance, and reduce the symptoms of stress.

There is limited evidence to support these claims, however. One study showed that glutamine supplementation improved muscle mass in patients recovering from surgery, but another study found no benefits.

There is some evidence that glutamine can improve exercise performance, but the benefits are small and inconclusive.

Finally, there is some evidence that glutamine can help reduce the symptoms of stress, but more research is needed to confirm these findings.

Are glutamine pills or powder better?

Glutamine pills and powder are both popular supplements that many people use to try to improve their health. But which one is better?

Powder is generally considered the better option because it is more bioavailable, meaning your body can more easily absorb and use it.

Pills can be less effective because they may not be fully dissolved and absorbed by your body. However, some people prefer pills because they are easier to take and don’t have a bitter taste.

Ultimately, the best option for you depends on your own preferences and what works better for your body. Talk to a doctor or nutritionist if you’re unsure about which form of glutamine would be best for you.

Who should not take L-glutamine?

People with kidney problems should not take L-glutamine because it is processed by the kidneys and people with kidney problems may have trouble clearing the amino acid from their system.

L-glutamine is also not recommended for pregnant women or lactating mothers because there is some evidence that it crosses the placenta and breast milk, and there isn't enough information yet to know whether it's safe for a developing fetus or nursing baby.

Lastly, people taking medicine for diabetes or blood pressure should consult with a doctor before taking L-glutamine because both of these medications can affect blood sugar levels and blood pressure.

How do I know if I need L-glutamine?

There are a few ways to know if you need L-glutamine.

First, if you have problems with wound healing, gut health, or immune function, then you may need more L-glutamine.

In addition, athletes and people who are under a lot of stress tend to use up more L-glutamine than the average person.

If you're not sure whether you need L-glutamine or not, it's best to speak with a healthcare professional about your specific situation.

What are the negative effects of L-glutamine?

L-Glutamine is an amino acid that is produced in the body and is also found in certain foods. It is used by the body to make proteins.

L-Glutamine has been studied as a possible treatment for a number of conditions, including cancer, alcohol addiction, and liver disease. However, most of the evidence for these uses is not conclusive.

L-Glutamine may have some negative effects, including increased ammonia levels and stomach problems such as cramps and diarrhea. It may also increase the risk of infection. L-glutamine should not be taken by people with kidney disease or liver disease. pregnant women, or children without supervision from a doctor.

Will L-glutamine make me gain weight?

No, L-glutamine will not make you gain weight.

Glutamine is an amino acid that is produced by the body and is used in many different ways including building muscle tissue.

Although it is possible to take too much glutamine, it is very difficult to do so and any excess will simply be excreted in the urine. Therefore, glutamine supplementation will not cause you to gain weight.

How much glutamine is needed per day?

Glutamine is a non-essential amino acid, which means that it can be produced by the body in adequate amounts. However, people who are sick or injured may need more glutamine than the body can produce, so supplementation may be necessary.

The recommended dose of glutamine varies depending on age and health status. Most people who are healthy and not injured only need a small amount of glutamine, around 500 mg per day. But people who are sick or injured may need up to 10 grams per day.

Does L-glutamine make you poop?

L-glutamine is an amino acid that is involved in many important bodily functions, including digestion. Because of this, some people believe that L-glutamine supplements can help with gastrointestinal issues like constipation.

However, there is no scientific evidence to support this claim. In fact, the only study that has been conducted on the matter found that L-glutamine actually worsened constipation symptoms in rats. So while L-glutamine may be good for your overall health, it is unlikely to have any effect on your bowel movements.

Is L-glutamine like creatine?

L-glutamine and creatine are two very different supplements, used for different purposes.

Creatine is typically used by athletes to help improve athletic performance, while L-glutamine is more often used by people looking to improve gut health or boost immunity.

That said, there are some similarities between the two: both are amino acids, and both have been shown to be effective in studies.

However, there are also some key differences between the two: for instance, creatine is much more well-studied than L-glutamine, and it's generally seen as being more effective for improving athletic performance.

So while they're similar in some ways, they're also very different supplements with different effects.

How long does it take for L-glutamine to work?

It typically takes about two weeks for L-glutamine to work. Some people may see a difference in as little as a week, while others may not see any change for several weeks.

L-glutamine is an amino acid that plays a role in many body functions, including muscle growth and repair, immune function, and brain health. It can be found naturally in foods like beef, chicken, and fish, but many people take it in supplement form to increase their levels.

Most of the research on L-glutamine has been done in animals, so there is limited evidence on its effects in humans. However, preliminary studies suggest that it may help with digestive issues like Crohn's disease and ulcerative colitis, as well as muscle-wasting conditions like cancer and AIDS.

Our Best Advice

Looking for the best glutamine supplement? We’ve spent dozens of hours reading thousands of reviews on Amazon from verified customers to find the perfect glutamine supplement for your needs.   Here are a few things to keep in mind.

The first thing to remember about finding the best l glutamine supplement is that it is first of all about gut health.  Yes, it can be used effectively for muscle growth and recovery and, obviously, it supports your immune system (which is why it is often given to people who are hurt or sick).  But stress and poor gut health can deplete your levels of glutamine and, therefore, repairing and reviving your digestive health is the first job.  The rest will come later.  Therefore, the best l glutamine supplement will focus first of all on gut health.

L-glutamine supplements (or a glutamine powder) can be a great source of amino acids outside of your normal diet but they should never simply replace a well-balanced diet or regular exercise.  It isn't clear whether a pure glutamine supplement is as important as a potent amount of glutamine per serving.  A good glutamine supplement will probably come in the form of a glutamine powder since a glutamine powder is easier to increase dosage or potency.

Most glutamine supplements have the recommended amount of l glutamine amino acid but, depending on what you want it for, a more potent dose may be beneficial.  For example, athletic performance may require a higher dosage for muscle growth and recovery as well as hurt or sick people who are in recovery.

Understanding your needs and purpose is one half of the equation but the other half is understanding the ingredients and what they can do for you.  Everything from a conditionally essential amino acid to branched-chain amino acids to protein synthesis to a healthy nitrogen balance becomes important.  Muscle glycogen synthesis and muscle protein synthesis can both benefit from l glutamine supplementation.

Intense exercise also requires an anti-fatigue amino acid to preserve lean muscle mass.  Glutamine functions as a major nitrogen transporter and glutamine peptides are essential to immune and digestive support since gut and immune cells need nutrition.  Glutamine stores are essential to muscle health and even skeletal muscle tissue (as well as lean muscle) will benefit from oral l glutamine supplementation.

As a workout supplement, the amino acid l glutamine together with vitamin c with a bcaa supplement in a protein shake is a good combination to deal with muscle soreness after a good workout.  L-arginine supports protein metabolism and is included in the best glutamine capsules.  So, the amino acid l glutamine together with vitamin c  (vitamin c supports the immune system) together with l arginine together with other bcaas amino acids supplements in different protein shakes is the best combination possible.

Some people have their favorites such as Optimum Nutrition Glutamine Supplements (one of the better amino acid supplement pills) or Sports Nutrition (which has a great workout supplement in the form of bcaa glutamine powders).  But all of the top brands provide this important amino acid in vegetarian glutamine capsules that are non-GMO gluten-free with a high dose of l glutamine per serving.  Some even provide glutamine powders that are not only non-GMO gluten-free but are a bcaa glutamine combo.

Bulk Supplements is another company that makes a great l glutamine supplement (and Bulk Supplements is always in the top ten best brands).  But the best amino acid supplement not only has the essential amino acids and pure l glutamine which is gluten-free but also has branched-chain amino acids as well.  Gluten-free is important to diabetics, of course, but the best l glutamine companies all know that already.

With all of that being said, it is now time to reveal our top choice for the best of the best in l glutamine supplements (including a good glutamine powder).  Drum roll, please...
