Glutamine supplementation has recently become a sports nutrition trend. Adding glutamine supplements to a sports nutrition routine is thought to help with high-intensity athletic activities.
Glutamine is predominantly used as an anti-fatiguing agent in sports nutrition. Several recent trends have shown glutamine supplementation being used to enhance overall physical performance. Is there merit in studying glutamine supplementation for multiple applications? The answer is yes, but let’s take a look at some details.
Glutamine is an amino acid that is found in high concentrations in the muscles and blood. It is considered a non-essential amino acid, which means that the body can produce it on its own, although it can also be obtained from dietary sources such as meat, fish, and dairy products.
Glutamine plays a variety of roles in the body, including supporting immune function, maintaining gut health, and aiding in the production of energy during exercise. It is also needed for protein synthesis and is a building block for other important molecules in the body, such as glutathione, which is a powerful antioxidant.
During periods of intense physical activity or stress, the body’s demand for glutamine may increase, and it may become a conditionally essential amino acid. Some athletes and bodybuilders may choose to supplement with glutamine to help support their training and recovery.
Evidence supporting the use of glutamine supplements in this context, however, is mixed and more research is needed to fully understand its effects.
The ‘energy’ that may be granted from glutamine supplementation has been linked to helping with fatigue. Many sports nutrition practitioners recommend glutamine as an anti-fatiguing agent.
During intense physical activity, the body’s demand for glutamine may increase, and it may become a conditionally essential amino acid. Glutamine is also involved in the production of energy. Some recent studies have linked glutamine to reduced fatigue and improved endurance in athletes.
Additionally, glutamine has been suggested to play a role in reducing fatigue associated with various medical conditions, such as cancer and chronic obstructive pulmonary disease (COPD). However, more research is needed to fully understand the effects of glutamine supplementation on fatigue in these populations.
Glutamine may have potential benefits for fighting fatigue, but more research is needed to fully understand its effects. Determining the optimal dosages and timing of supplementation is an area of study that desperately needs more research.
There are many potential applications of glutamine supplementation currently being researched. A recent joint study funded by the Sao Paulo Research Foundation listed 6 important findings:
Glutamine supplementation has shown many potential benefits but more research needs to be conducted. While its use as an anti-fatiguing agent shows merit, using glutamine to enhance general physical performance needs more research.
