What L-Glutamine does
According to MedlinePlus, L-glutamine is in a class of medications called amino acids. It is used to reduce the frequency of painful episodes (crises) in adults and children 5 years of age and older with sickle cell anemia. MedlinePlus notes it comes as a powder mixed with a liquid or soft wet food and taken by mouth twice a day. The page presents L-glutamine as a prescription medication for this specific condition rather than describing other uses. It advises continuing your normal diet unless your doctor tells you otherwise. — per NIH MedlinePlus; not medical advice.
Forms & absorption
Per MedlinePlus, L-glutamine comes as a powder to be mixed with a liquid (such as 8 ounces of water, milk, or apple juice) or 4 to 6 ounces of a soft wet food and taken by mouth twice a day. — per NIH MedlinePlus; not medical advice.
L-Glutamine — safety & side effects
MedlinePlus lists possible side effects including constipation, nausea, headache, abdominal pain, cough, and pain in the back, legs, feet, hands, or arms. It advises telling your doctor and pharmacist if you are allergic to L-glutamine or any other medications, and telling your doctor if you are pregnant, plan to become pregnant, or are breastfeeding, and to call your doctor if you become pregnant while taking it. — per NIH MedlinePlus; not medical advice.
L-Glutamine — interactions & cautions
MedlinePlus advises telling your doctor and pharmacist what prescription and nonprescription medications, vitamins, nutritional supplements, and herbal products you are taking or plan to take, noting your doctor may need to change the doses of your medications or monitor you carefully for side effects. — per NIH MedlinePlus; not medical advice.
