Ingredient and preparation
L-glutamine is an amino acid and a common ingredient in single-ingredient and mixed products.
Sources: National Institutes of Health, Office of Dietary Supplements
Evidence and limits
NIH ODS reports that a six-week weightlifting study found no difference in performance, lean mass or muscle-protein degradation. A small eccentric-exercise study found faster recovery, but that does not establish a general “gut health” or immunity claim.
Sources: National Institutes of Health, Office of Dietary Supplements
Safety and a useful record
Amino-acid products may be inappropriate in some medical contexts or with some treatments. The relevant safety question is the person, full product and reason for use.
Sources: National Institutes of Health, Office of Dietary Supplements, National Center for Complementary and Integrative Health
