Recovery evidence brief
Glutamine is an amino acid often used for recovery, soreness, immune support, and gut health. It remains popular despite weak muscle-building evidence in well-fed lifters.
Healthy, well-fed lifters are unlikely to see meaningful performance, muscle-gain, or recovery benefits.
Athletic-performance meta-analysis and reviews do not support meaningful benefits for healthy, well-fed lifters.
Not recommended as a first-line supplement for healthy, well-fed users.
Clinical and gut-stress contexts are separate from general performance claims.

The score reflects evidence that the supplement does its stated job. Some jobs are direct, such as strength, endurance, or recovery; others are indirect, such as sleep, mood, appetite, or health support. A real effect can still receive a cautious practical rating when dose, safety, product quality, or audience fit remain uncertain.
Send the disputed claim, source link, and why it changes the practical verdict. Corrections that materially affect the claim, dose, caveat, or rating are prioritized.
