You've probably heard the word "glutamine" somewhere. Maybe from a friend, or the internet, or even a doctor. So, what is this glutamine? How important is it really for our bodies? Today, we'll talk about all this in a very simple way, in a way that you can understand.
Do you know what this glutamine is?
Simply put, Glutamine is a type of amino acid found in our bodies. The word amino acid sounds a bit strange to you, doesn't it? Think of it this way, just like building a house requires bricks, our bodies need these amino acids to build proteins. So Glutamine is like a "brick" to build proteins.
These proteins help our bodies do a lot of things. For example, proteins are essential for healing wounds, keeping our intestines working properly, and helping our immune system protect us from disease. So, as a part of making these proteins, glutamine also plays a big role in these tasks.
Is Glutamine essential for our bodies?
Here's a little thing. Glutamine is a "conditional nonessential amino acid." This sounds a little confusing, doesn't it? I'll keep it simple.
"Nonessential" means that we get it from food, and it is also produced in our bodies. (However, "essential" amino acids are not produced in our bodies, we must get them from food.)
"Conditional" means that although our bodies normally produce enough glutamine internally, in some special cases our bodies need more glutamine .
Think about it, when you have a cold, or a minor injury, your body uses up more of this glutamine. At times like that, the amount produced in the body may not be enough. Then we have to get more glutamine from the outside, either through food or perhaps through supplements.
However, most healthy adults usually produce enough glutamine in their bodies, so this is not something to worry about all the time.
Are there types of Glutamine?
Yes, there are two main types. They are L-glutamine and D-glutamine.
Of these two, the most important for our body's functions is L-glutamine . Most of the time, when someone says "glutamine," they are referring to this L-glutamine.
How does Glutamine help our body?
Glutamine is not just a protein building block. It does much more than that.
- This also helps make other amino acids .
- It also helps to remove unwanted waste products from our bodies, such as ammonia .
- This is also very important for the chemical processes that provide our bodies with the energy they need, that is, metabolic processes.
Glutamine primarily helps these systems of ours the most:
Cheers to the immune system!
The immune system is like an army that fights to protect our bodies from disease. So, glutamine is one of the main fuels that provides the energy needed for this immune system.
- The white blood cells in our body use this glutamine to protect us from germs and keep us healthy.
- This is also very important for the processes that repair injured tissue in the body.
Helps the digestive system!
Did you know that most of the white blood cells in our immune system are located in our intestines? Glutamine strengthens the intestinal wall, preventing it from getting damaged. It also helps maintain a healthy intestinal system.
What foods contain glutamine?
Most of the glutamine we get from food comes from protein-rich animal foods, but it is also found in other foods.
- Meats: Like beef, pork, chicken.
- Dairy products: eggs, milk, yogurt, cheese.
- Other plant-based foods rich in protein: various nuts, tofu.
- Vegetables: corn, red cabbage.
- Cereals: rice, oats.
For most healthy people, they get enough glutamine from their regular diet. There's no need to worry about it. Because, as I said before, the body can make it on its own if it needs it.
In what situations is Glutamine used as a supplement?
Glutamine, which is produced by our bodies, is so important to our overall health that scientists are still researching the benefits of taking glutamine supplements. However, most studies show that healthy people do not need glutamine supplements. A healthy body can make enough glutamine and can get it from a normal diet.
However, some research has found that taking glutamine may have some benefits in treating certain medical conditions. However, the evidence is not always clear. In many cases, more research is needed to understand the true benefits of taking glutamine.
Now let's see in what situations this glutamine is being talked about:
Sickle Cell Disease (SCD)
The only time the U.S. Food and Drug Administration (FDA) has approved glutamine for use is to reduce the severe complications of sickle cell disease. This disease causes the red blood cells to change shape. These abnormally shaped red blood cells can get stuck in our blood vessels (veins, arteries, capillaries). L-glutamine (brand name: Endari®) can reduce symptoms such as pain.
Burns or injuries
During trauma, such as severe burns, surgery, or other severe injuries, our body's glutamine levels can decrease. When we don't have enough glutamine, our immune system can't function properly.
Some research suggests that giving extra glutamine to people who are seriously ill or injured may be beneficial . It may help prevent or reduce infections after surgery. It may also reduce damage to internal organs after severe burns. In studies that have shown the benefits of glutamine in these situations, glutamine has often been given to hospital patients through a feeding tube.
However, it is not yet entirely clear whether everyone will get the same results from taking glutamine after an injury. It may vary from patient to patient and depending on the situation.
Cancer
Like healthy cells, cancer cells use glutamine as an energy source for their growth and spread. In fact, cancer cells use more glutamine than healthy cells. Sometimes they use so much glutamine that healthy cells don't even have enough to do their job. This is why cancer patients have low glutamine levels.
Scientists are researching ways to stop these cancer cells from using glutamine, but that research is still in its early stages.
But glutamine isn't just a cancer-fighting nutrient. It also has benefits for cancer patients. Some studies have shown that glutamine supplementation may help tissue heal after cancer treatment . For example, glutamine may help reduce the pain caused by sores and inflammation in the mouth and esophagus (mucositis) after chemotherapy. It may also help relieve symptoms of neuropathy after chemotherapy.
More research is needed to understand exactly how glutamine helps reduce the side effects of cancer treatments.
HIV/AIDS
Some studies suggest that glutamine supplements may be helpful for people with HIV and AIDS. Glutamine may help them regain some of the weight they lost after contracting HIV. It is also said to be able to enhance the effectiveness of antiviral medicines used to treat HIV.
However, research is still being conducted on whether or not doctors should recommend these glutamine supplements.
Inflammatory Bowel Disease (IBD)
Because glutamine helps maintain the protective lining of the intestines, some researchers have studied whether glutamine supplements might help people with inflammatory bowel disease (IBD). IBD is a chronic inflammatory condition of the intestines. Although studies have been conducted, glutamine supplementation has not been proven to help IBD.
Athletes' athletic performance
Researchers have also investigated whether glutamine can improve athletic performance. Several studies have shown that glutamine may help reduce muscle soreness and reduce the risk of injury after intense exercise. However, there is not enough evidence to say that these benefits are permanent. The idea that glutamine helps athletes build muscle mass is not supported by research.
So, should you take Glutamine?
The simple answer is: only if your doctor recommends it. If you have sickle cell disease (SCD), your doctor may prescribe glutamine. If your immune system needs an extra boost, your doctor may advise you to take a glutamine supplement or eat more glutamine-rich foods.
The most important thing is to inform your doctor about any supplements you are taking. Only then can they tell you if it is safe for your health condition.
What are the benefits of taking this?
Taking glutamine may reduce the risk of complications of sickle cell disease (SCD). It may also have some potential to prevent infections and reduce tissue damage that can occur after trauma (injury or burns) or cancer treatment, but more research is needed.
Scientists continue to research other benefits, but that research is still in its early stages.
Does L-glutamine reduce belly fat?
There is no clear, conclusive evidence that taking L-glutamine reduces belly fat or helps with weight loss.
Are there any side effects?
More research is needed to understand the possible side effects of taking glutamine long-term. For example, taking glutamine supplements may change the way your body uses amino acids to create energy. That's why it's important to talk to your doctor before taking glutamine (or any other supplement).
Here are some of the minor side effects that may occur when taking L-glutamine for sickle cell disease (SCD):
- Abdominal pain
- Back pain
- Constipation
- Headache
- Nausea
If you experience any allergic reaction (for example, skin rash or hives), you should inform your doctor immediately.
Finally, things to remember
Glutamine is an amino acid that is abundant in our bodies and essential for a variety of functions. It is so essential that it is common to think that taking a glutamine supplement will provide significant health benefits. However, before taking a glutamine supplement, it is important to be realistic about the evidence.
- Taking glutamine helps with sickle cell disease (SCD).
- In "conditional" situations where our bodies need more glutamine than normal, this may be able to give the immune system an extra boost.
- However, if you are generally healthy, there is not yet enough solid evidence to say that taking glutamine provides significant health benefits.
Therefore, before taking glutamine or any other supplement, be sure to talk to your doctor. They can advise you on the potential benefits and risks based on your health condition.
Got it? If you have any more questions, don't be shy about asking the doctor.
