About L Glutamine Supplements

Though Glutamine is not one of the nine essential amino acids, it is a conditionally essential amino acid. This means, the human body can synthesize it, though under certain conditions not enough can be synthesized to meet requirements. During exercise, it has been shown that muscle glutamine levels decline, which makes post-workout supplementation helpful for recovery. Muscle tissue naturally contains an abundance of this amino acid, whcih promotes health well beyond its roles in exercise and recovery.


L-Glutamine powder can be useful when engaging in high-volume training and during the colder months of the year, as it may support the immune system. Other nutrients involved in immune health are zinc, quercetin 1and vitamin C, to name a few. Glutamine is required for synthesis of the most powerful antioxidant that the body synthesizes, called glutathione. Glutathione helps to neutralise free-radicals, which are prodiced at high rates during aerobic exercise (as a normal part of oxygen-dependent energy pathways). The Medical Science Monitor in 2002 reported that 3-10% of oxygen utilised by tissues is converted to free-radicals.


Glutamine is an important energy source for intestinal cells. Evidence indicates that it is needed for intestinal cell proliferation and helps to regulate normal absorption of nutrients. This was published in the International Journal of Molecular Sciences in 2017. L-Glutamine is an intestine-specific amino acid, indicated for intestinal or gastric ulcerations and inflammation.


Research indicates glutamine supplementation boosts glycogen accumulation, which is helpful for endurance athletes or anyone involved in high volume training. Research also indicates that glutamine supplementation increases peak torque and decreases muscle soreness. Glutamine is relatively tasteless when mixed in water and for this reason is most commonly sold unflavoured and unsweetened. Alternatively, it can be mixed into protein shakes and taken after training or before food to support GUT health.
