L Glutamine Immune: The Best Immune Support Powder

L Glutamine is the most common amino acid found in your muscles and can assist with muscle repair and immune recovery due to having a positive effect on the body’s nitrogen levels.

During intense exercise glutamine levels become greatly depleted which causes a decrease in strength, stamina and recovery. Supplementing with L Glutamine can help to replenish the body’s glutamine levels, promoting muscle recovery.

L Glutamine has shown to have anti-catabolism properties that work to prevent muscle wastage.

Studies have revealed that Glutamine can help minimise breakdown of muscle and can improve protein metabolism. This is especially useful for those dieting and wanting to preserve muscle.

About Glutamine

Glutamine is a non-essential amino acid which is abundant in the body. It occurs naturally in some foods including dairy and meat but can be synthesised by the body. Glutamine can be beneficial for immune and gut health while having a positive effect on muscular recovery.

During times of increased physical and mental stress glutamine levels can be negatively affected, so supplementing with Glutamine can be beneficial during these periods.

Glutamine FAQs

What does L Glutamine do?

Glutamine is a conditionally essential amino acid which is abundant in the body. It becomes an “essential” amino acid when the body is in a heavily compromised state, ie when it is fighting disease. Glutamine is most useful for its effect on immune and intestinal health.

How much evidence is there for Glutamine's benefits?

Most of the evidence supporting the use of Glutamine comes from those who have Glutamine deficiencies. This is most likely to come from a very low protein intake, eg cases of veganism.

There is also evidence for Glutamine assisting exercise preservation, as it prevents the body depleting glutamine stores which can occur in longer endurance activities.

Is Glutamine good for building muscle?

There is not much evidence to support Glutamine use for building muscle. It is likely it has a positive effect on recovery from strenuous sessions and could reduce occurrences of sickness for serious endurance athletes.

Can Glutamine be converted directly to glucose?

Yes, when carbohydrates are in short supply, Glutamine can convert into glucose in the body. It should be noted that studies showed when paired with a carbohydrate, glutamine reduces the blood glucose response compared to if a carbohydrate is used alone.

Can Glutamine prevent me from getting sick?

Much of Glutamine’s benefits are in relation to the intestinal and immune systems, however there is more evidence that it supports repair from sickness rather than preventing it.
