GLUTAMINE can be naturally found in beans, poultry, fish and dairy products. It is one of the most abundant amino acids in the body and is called a conditionally essential amino acid, meaning that the body is able to manufacture Glutamine on its own, but during times of extreme stress (such as following an intense workout), the body is not able to produce enough and may benefit from supplemental Glutamine. Glutamine is a natural supplement and can be used by anyone who may benefit from it. It is ideal for athletes and those who perform intense workouts, as it can help to speed up recovery and maintain muscle mass. However, it is also used in the hospital in extreme cases such as burn patients and those suffering from cancer to boost their immune system.
