and cancer<span class=\"ez-toc-section-end\"><\/span><\/h1>\n\n\n\n<h4 class=\"wp-block-heading\">What is L-Glutamine<\/h4>\n\n\n\n<p class=\"wp-block-paragraph\">L-Glutamine is a non-essential amino acid (a building block of proteins). The &#8220;L&#8221; prefix indicates the amino acid&#8217;s stereochemistry (the structure of the molecules), specifically the levo-rotatory form (left-handed molecular form), which is the natural and biologically active isomer used in the body&#8217;s processes.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The body is normally capable of producing sufficient quantities of this amino acid. L-Glutamine is involved in important functions such as protein production, the immune system, and the maintenance of the intestinal wall.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">It is found in various foods, especially animal products and to a lesser extent in certain plants. In the body, the muscles are the largest reservoir of L-Glutamine. The amino acid is also essential for rapidly growing cells, such as immune cells and intestinal cells, which use it as their primary energy source.<\/p>\n\n\n\n<h4 class=\"wp-block-heading\">History<\/h4>\n\n\n\n<p class=\"wp-block-paragraph\">Although L-Glutamine has always been part of the human diet, its specific importance during physiological stress was first investigated in the mid-20th century. Clinical interest emerged in the 1980s and 90s within areas such as parenteral nutrition (IV nutrition), the treatment of severe burns, and intensive care.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Research began to highlight its role in modulating the immune system and supporting gut health, leading to studies on its potential as a supplementary treatment for cancer.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Mechanisms_of_action\"><\/span>Mechanisms of action<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<figure class=\"wp-block-image size-thumbnail is-resized\"><img loading=\"lazy\" decoding=\"async\" width=\"150\" height=\"150\" src=\"https:\/\/jegharkraeft.dk\/wp-content\/uploads\/2025\/05\/L-Glutamin3-150x150.png\" alt=\"L-Glutamin symboliseret ved skematisk illustration af menneske med tegning af organer i kreds om denne.

During cancer treatment, where both the immune system and the gastrointestinal system are often under pressure, an adequate supply of L-Glutamine can support the function of these cells and help maintain the health of the intestinal wall.<\/p>\n\n\n\n<h4 class=\"wp-block-heading\">Nitrogen carrier and amino acid synthesis<\/h4>\n\n\n\n<p class=\"wp-block-paragraph\">L-Glutamine also serves as an important carrier of nitrogen between different tissues and is involved in the formation of other amino acids and nucleotides, which are the building blocks of DNA and RNA. This function is essential for cell growth and repair, which can be relevant in connection with the rebuilding of tissues damaged by cancer or cancer treatment.<\/p>\n\n\n\n<h4 class=\"wp-block-heading\">Antioxidant function<\/h4>\n\n\n\n<p class=\"wp-block-paragraph\">Indirectly, L-Glutamine can help protect cells from damage by supporting the production of glutathione, a powerful antioxidant that neutralizes harmful free radicals that can be formed during cancer treatment.<\/p>\n\n\n\n<h4 class=\"wp-block-heading\">Regulation of inflammation<\/h4>\n\n\n\n<p class=\"wp-block-paragraph\">Research suggests that L-Glutamine may have a modulating effect on inflammation by helping to reduce the production of pro-inflammatory signaling molecules (cytokines) and promoting the formation of anti-inflammatory cytokines. This balance is important for managing inflammatory processes that may be involved in both the cancer itself and the side effects of treatment.<\/p>\n\n\n\n<h4 class=\"wp-block-heading\">Support of the intestinal barrier<\/h4>\n\n\n\n<p class=\"wp-block-paragraph\">A well-studied mechanism of action is L-Glutamine&#8217;s ability to strengthen and maintain the gut&#8217;s barrier function. The intestinal mucosa prevents harmful substances from entering the body.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">During stress such as chemotherapy, this barrier can be weakened. L-Glutamine is an important energy source for intestinal cells and supports their growth and function, which is necessary to maintain an intact intestinal barrier and potentially reduce the risk of complications.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Potential_as_supplementary_treatment_for_cancer\"><\/span>Potential as supplementary treatment for cancer<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">L-Glutamine shows potential for reducing certain challenges associated with cancer treatment.<\/p>\n\n\n\n<h4 class=\"wp-block-heading\">Reduction of chemotherapy-induced mucositis<\/h4>\n\n\n\n<p class=\"wp-block-paragraph\">Several studies indicate that L-Glutamine can reduce the severity and duration of mucositis, a painful inflammation of the mucous membranes that often occurs during chemotherapy and radiation therapy. This is likely due to L-Glutamine&#8217;s ability to promote the healing of mucosal cells and strengthen the intestinal barrier.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">See also <a target=\"_blank\" rel=\"noreferrer noopener\" href=\"https:\/\/jegharkraeft.dk\/en\/mundtoerhed-smerter-saar\/\">Dry mouth, pain, and mouth sores<\/a><\/p>\n\n\n\n<h4 class=\"wp-block-heading\">Support of immune function during treatment<\/h4>\n\n\n\n<p class=\"wp-block-paragraph\">Cancer treatment can weaken the immune system. L-Glutamine is important for the function of immune cells, and supplementation can potentially help maintain the immune system&#8217;s ability to fight infections during treatment.<\/p>\n\n\n\n<h4 class=\"wp-block-heading\">Improvement of nutritional status and reduction of weight loss<\/h4>\n\n\n\n<p class=\"wp-block-paragraph\">By supporting healthy gut function, L-Glutamine can indirectly contribute to improving the absorption of nutrients and potentially counteract unintended weight loss, which is common among cancer patients.<\/p>\n\n\n\n<h4 class=\"wp-block-heading\">Reduction of peripheral neuropathy<\/h4>\n\n\n\n<p class=\"wp-block-paragraph\">Some preliminary studies suggest that L-Glutamine may have a protective effect against the development or severity of peripheral neuropathy, a type of nerve damage that can occur as a side effect of certain chemotherapies.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">See also <a target=\"_blank\" rel=\"noreferrer noopener\" href=\"https:\/\/jegharkraeft.dk\/en\/nerveskader-foleforstyrrelser\/\">Nerve damage\/sensory disturbances in Chemo &#8211;
