The Benefits of Glutamine

What is glutamine?

Glutamine is an essential amino acid that is found naturally in our body.  The body requires glutamine when we are injured or ill, but there are some other incredible other benefits.


What are the benefits of glutamine?

It can improve our immune system.  Our immune cells need glutamine as it's energy source and a deficiency can lead to a weakened immune response.  Glutamine has also been shown to reduce the length and severity of illnesses and infections.


It can improve our gut health.  The cells that line our gut need glutamine as their energy source and a deficiency can lead to inflammation and damage to the gut lining, also known as, 'leaky gut.'  Supplementation with glutamine can help repair the gut barrier and reduce the risk of infections related to the gut.


It can help in muscle growth and recovery.  Our muscle tissues are composed of glutamine and after intense exercise glutamine is released by our muscles into the bloodstream to be used by other tissues.  Glutamine supplementation can reduce soreness and improve muscle recovery after exercise.


Are there any side effects?

Always make sure to check with your doctor before starting any supplement.


Although glutamine is safe, some side effects may include:

  • Nausea 
  • Stomach cramps
  • Allergic reactions
  • Glutamine may interact with some medications, particularly those that affect the immune system. It is important to speak with a healthcare professional before taking glutamine if you are on medication.
  • Glutamine may not be recommended for people with certain medical conditions, such as liver disease, kidney disease, or autoimmune disorders.
