The Claim
GlyNAC supplementation for 24 weeks improves muscle strength, gait speed, and exercise capacity in older adults, and these improvements diminish after discontinuation of supplementation.
What the research says
Roughly balanced
Support and challenge are close. The picture may shift as more studies come in.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
Taking GlyNAC daily for 24 weeks increases muscle strength, walking speed, and exercise ability in older adults, and these improvements decrease when supplementation stops.
See the scientific wording
GlyNAC supplementation for 24 weeks improves muscle strength, gait speed, and exercise capacity in older adults, with benefits diminishing after discontinuation, suggesting a need for ongoing use to maintain functional gains.
GlyNAC gives the body the building blocks to make more glutathione, which cleans up harmful molecules that damage muscles and mitochondria. This lets mitochondria produce more energy efficiently, reduces muscle breakdown, and improves how muscles contract and resist fatigue. When GlyNAC stops, glutathione drops, damage returns, and strength and endurance decline.
What the research says
1 studyTaking GlyNAC for 6 months helped older adults walk faster and get stronger, but when they stopped taking it, those improvements went away—so they need to keep taking it to stay strong and mobile.
