What is L-glutamine?

L-glutamine is an amino acid that is commonly found in the human body. It is one of the 20 most common amino acids, and it makes up around 30% of the amino acids in muscle tissue. L-glutamine has many important functions in the body, including:

>> Playing a role in immune function

>> Helping to heal wounds

>> Supporting gut health

>> Acting as a source of fuel for cells

L-glutamine supplements are often marketed as being helpful for a variety of conditions, such as:

>> Muscle soreness

>> Exercise recovery

>> Immunity support during illness or infection

>> Digestive issues

There is some scientific evidence to support the use of L-glutamine supplements for these purposes. However, more research is needed to confirm the effectiveness of L-glutamine supplements for these uses.

The body is able to make its own L-glutamine, and people generally get enough of it from their diet. However, some people may benefit from taking an L-glutamine supplement. This is especially true for people who are ill or have a wound that isn’t healing properly.

L-glutamine supplements are available in a variety of forms, including capsules, tablets, powders, and liquids. They can be purchased online or at many health food stores.

If you’re considering taking an L-glutamine supplement, be sure to talk to your healthcare provider first. They can help you determine if an L-glutamine supplement is right for you and make sure it won’t interact with any other medications or supplements you’re taking.
