The Claim
In aged male mice, 12 weeks of GlyNAC supplementation is associated with a 21% increase in Fmod protein expression in heart tissue, where Fmod is a protein that inhibits collagen fibril formation, indicating a reduction in extracellular matrix stiffness.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
In older male mice, taking GlyNAC for 12 weeks increases Fmod protein levels in the heart by 21%, and this protein reduces collagen fiber formation, leading to lower stiffness in heart tissue.
See the scientific wording
In aged male mice, GlyNAC supplementation for 12 weeks is associated with a 21% increase in Fmod protein expression in heart tissue, a protein that inhibits collagen fibril formation, suggesting a sex-specific reduction in extracellular matrix stiffness.
GlyNAC provides building blocks that boost glutathione levels in heart cells, which reduces oxidative damage and improves the mitochondria's ability to burn fatty acids for energy. This improved energy production turns on a gene that makes Fmod protein, which blocks collagen fibers from forming tightly packed bundles, making the heart tissue less stiff.
What the research says
1 studyIn older male mice, a special diet with GlyNAC made a heart protein called Fmod go up by 21%, which helps prevent stiff collagen buildup — but this didn’t happen in female mice. The study directly measured this and found exactly what the claim says.
