GI Repair Nutrients By Vital Nutrients Overview & Drug Interactions

L-glutamine is the most abundant free amino acid in the body, produced primarily in skeletal muscle and then released into circulation. It serves vital roles in various tissues, including the immune system, gastrointestinal tract, kidneys, and liver, where it supports essential functions such as maintaining intestinal integrity, immune response, and amino acid balance. Although traditionally classified as a non-essential amino acid, during periods of severe stress, glutamine becomes conditionally essential due to the body's increased demand. It acts as a critical nitrogen and carbon transporter between organs, and while the intestinal mucosa can synthesize glutamine, this production is insufficient during times of significant physiological stress. Dietary supplements generally contain L-glutamine as it is the biologically active form of the amino acid.

Glucosamine is a natural compound found in the body, particularly in the fluid that surrounds joints. It is often used as a dietary supplement to help with joint health, particularly for conditions such as osteoarthritis. Glucosamine is believed to work by helping to reduce inflammation, promoting the repair of damaged cartilage, and slowing down the loss of cartilage. There are several different forms of glucosamine supplements, including glucosamine sulfate, glucosamine hydrochloride, and N-acetyl-glucosamine. Glucosamine sulfate is the most commonly used form in supplements. It is important to note that glucosamine sulfate is derived from shellfish (specifically the exoskeletons of shrimp, lobster, and crabs) and can be problematic for people with shellfish allergies.

Arabinogalactans are long, densely branched, high-molecular weight polysaccharides found in many plants, with the highest concentrations in larch trees. Larch arabinogalactan, specifically obtained from the western larch (Larix occidentalis) and eastern larch (Larix laricina), is approximately 98% arabinogalactan. This polysaccharide has a range of potential health benefits, including serving as a soluble, non-viscous fiber that ferments in the gut, potentially increasing beneficial gut bacteria like Lactobacillus. Additionally, larch arabinogalactan has been investigated for its possible role in drug delivery systems due to its water solubility and numerous hydroxyl groups, which may enhance the bioavailability of drugs like ibuprofen. Moreover, preliminary research suggests immunostimulatory effects, such as increased natural killer cell activity and enhanced immune response to certain vaccines.

Quercetin is a type of flavonoid, which is a class of compounds found in a wide variety of plants and foods. It is purported to have a number of health benefits such as anti-inflammatory, antioxidant, and immune-boosting effects. Studies suggest it may also help to reduce the risk of certain chronic diseases, such as heart disease. In addition, quercetin may have anti-allergic properties and may be helpful in the treatment of allergies and asthma. It is a popular dietary supplement worldwide and is often included in products that contain antioxidants or various vitamins/minerals. Its wide range of potential health benefits mean that it could potentiate the effects of other drugs (e.g., anti-hypertensives), which is why there are an abundant number of potential interactions listed for quercetin.

Licorice, also known as glycyrrhiza, is a plant native to parts of Europe, Asia, and the Mediterranean region. The root of the plant has been used for centuries in traditional medicine and is often consumed in the form of candy, tea, and supplements. Licorice has a number of purported health benefits, including the ability to soothe sore throats, reduce inflammation, and improve digestive problems. It may also have antiviral and antibacterial properties. Licorice naturally contains glycyrrhizin, or glycyrrhizic acid, which can have toxic effects if consumed in large amounts. However, licorice can be processed to remove glycyrrhizin, resulting in DGL (deglycyrrhizinated licorice). Many dietary supplements that contain deglycyrrhizinated licorice are often simply named 'DGL'.

Bacillus coagulans, also known as Weizmannia coagulans or Lactobacillus sporogenes, is a spore-forming, lactic acid-producing, Gram-positive bacterium used as a probiotic. Bacillus coagulans has shown benefits for constipation and irritable bowel syndrome (IBS). Its spores are stable in stomach acid and reach the small intestine, where they germinate and multiply, with around 85% reaching their destination. The bacterium is excreted via feces, with spores detectable up to 7 days post-administration. Mechanistically, Bacillus coagulans exhibits antibacterial effects through the production of coagulin, lactic acid, and lactosporin, reducing pathogenic bacteria colonization. It also demonstrates antifungal properties and anti-inflammatory effects, potentially reducing the growth of pathogenic bacteria and decreasing the production of lipopolysaccharides. Bacillus coagulans may stimulate immune response, as evidenced by increased CD4+ T cells in adults with HIV-1 infection and modulation of inflammatory cytokines in schoolchildren. These properties categorize Bacillus coagulans as an immunomodulator, immunostimulant, and probiotic, with potential therapeutic applications in promoting digestive health and immune function.

Ginkgo (Ginkgo biloba) is a tree native to Asia and is known for its distinctive fan-shaped leaves. The extract of the ginkgo leaf is commonly used in traditional medicine and is one of the most popular dietary supplements consumed worldwide. Its most common use is to help improve memory and cognitive function.
