Glutamine is the most abundant amino acid in our bodies. It works to support many healthy functions, including:
Making proteins for muscle tissue
Fueling cells that protect our intestines
Supporting immune system cells
Helping to detoxify the liver of foreign substances
Your body makes glutamine, but we also consume it in foods like wheat, peanuts, corn, and milk. Deficiency is very rare and not caused by inadequate intake but from a genetic disorder.
However, research suggests that supplementing with glutamine may offer some health benefits, and scientists continue to study the amino acid’s potential to prevent or treat certain conditions.
While our body makes the glutamine it needs to function, it may require more when stressed from injury or illness.
Many clinical studies show that glutamine helps ease the effects of cancer treatments, like muscle wasting, oral inflammation, nausea, vomiting, and diarrhea. Supplementation is also linked with shorter hospital stays and lower mortality rates for sick patients.
These findings are supported by research on glutamine’s health effects, including:
Immune System Support
Glutamine is the main fuel source for your body’s lymphocytes, white blood cells that fight infection and disease. But your blood’s glutamine levels decline when we’re sick or injured, reducing these immune cells’ ability to defend your body.
While there’s conflicting evidence on whether it boosts immunity in healthy people, studies show it can improve recovery times and reduce complications when you’re sic
