What exactly is L-glutamine?
L-glutamine is a proteinogenic, non-essential amino acid that the body can produce itself. However, the body’s own production may be reduced in stressful situations, during illness, or intense physical exertion – especially in competitive athletes – making glutamine supplementation potentially beneficial.
Glutamine is closely related to glutamic acid; both are central building blocks of proteins and can be converted into one another. At around 20%, glutamine accounts for the largest proportion of all free amino acids in human blood plasma, while the highest concentration is found in muscle tissue.
In foods, L-glutamine is found exclusively in bound form. Plant-based sources include soy and wheat, among others.
L-glutamine is an important component of glutathione. Together with the amino acids cysteine and glycine, it is involved in its formation. Glutathione is an important antioxidant in the human body that protects cells from oxidative stress and neutralizes harmful free radicals.
When and how should glutamine be taken?
We recommend taking 5 g of L-glutamine powder twice daily. Alternatively, with our capsule product, you can take 8 capsules daily, swallowed whole with sufficient liquid. The best time to take it is before or after training, as well as in the evening before going to sleep.
Are there any risks associated with taking it?
In general, L-glutamine is suitable for every athlete. However, supplementation should be discussed with your treating physician beforehand. Particular caution is advised for pregnant and breastfeeding women, as well as individuals with diabetes, epilepsy, or impaired kidney function.
Glutamine vs. Glutamate
Glutamate is also a natural amino acid that is produced during the metabolism of L-glutamine and plays an important role as a neurotransmitter in the transmission of sensory perceptions, motor control, as well as learning and memory performance.
However, it has little to do with flavor enhancers that are said to cause the so-called Chinese Restaurant Syndrome (headaches, stomach aches, feeling of heat, etc.): these involve isolated glutamate chemically combined with various salts. Examples include monosodium glutamate (E621), monopotassium glutamate (E622), or calcium diglutamate (E623). They are used in industrially processed foods to enhance flavor and belong to the large group of food additives.
