NOW Foods L-Glutamine 1000mg
by NOW Foods
Free-form L-glutamine capsules providing 1000mg per serving, the most abundant amino acid in the body. Glutamine supports muscle recovery, immune function, and intestinal health. Particularly popular among those with gut health concerns and athletes undergoing heavy training loads. NOW Foods provides a well-priced, straightforward glutamine supplement.
AI Review Summary
NOW Foods L-Glutamine is a reliable capsule option for those wanting to supplement this conditionally essential amino acid. Evidence is strongest for gut health and immune support during heavy training, though general muscle-building claims are weaker. At 1g per capsule, higher therapeutic doses (5-10g) would require switching to powder format. Priced competitively and backed by NOW's manufacturing standards. A reasonable supplement for gut health support, but the muscle recovery marketing may overpromise.
