L-Glutamine
The most abundant amino acid in the body; a fuel source for gut and immune cells. Marketed for recovery, gut health, and immunity.

What the evidence says
Strongest rationale is in clinical catabolic states (critical illness, gut injury). For healthy resistance-trained athletes eating sufficient protein, performance/hypertrophy benefits are limited.
Typical dose & timing
Dose: Commonly 5 g/day in supplements; clinical gut protocols differ and should involve a clinician.
Timing: Any time; consistency over timing.
Role in a stack
Optional recovery/gut add-on. For most lifters eating enough total protein, added glutamine is redundant.
Redundancy check: Whole-protein sources (whey, food) already supply glutamine. Extra glutamine is often unnecessary if protein intake is adequate.
Cautions & safety
Generally well tolerated. Benefits for muscle growth or performance in healthy, well-fed lifters are not well supported.
Considered safe for healthy adults at typical doses. Educational only — talk to a clinician for clinical gut conditions.
