L-Glutamine is a semi-essential amino acid, which means that our body cannot produce it sufficiently in certain situations, such as during intensive sports practice. Athletes and people who train intensively often have an increased need for glutamine.
Glutamine occurs naturally in meat, fish and dairy. However, these sources are sometimes not sufficient to meet the increased needs, so supplementation may be necessary. In addition to animal sources, we also find glutamine in plant-based, protein-rich foods such as beans, grains and some vegetables.
Glutamine, like all amino acids, plays a crucial role in various biochemical processes in our body. Amino acids are often referred to as the 'building blocks of life'.
