The Claim
In aged male mice, 12 weeks of GlyNAC supplementation increases CPT1b enzyme activity by 101% and CrAT enzyme activity by 88% in heart mitochondria, with no change observed in females.
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 the activity of two enzymes in heart mitochondria—CPT1b by 101% and CrAT by 88%—which are involved in fatty acid metabolism; no such changes occur in female mice.
See the scientific wording
In aged male mice, GlyNAC supplementation for 12 weeks is associated with a 101% increase in CPT1b enzyme activity and a 88% increase in CrAT enzyme activity in heart mitochondria, both involved in fatty acid metabolism, with no effect observed in females.
GlyNAC provides building blocks that increase glutathione, which removes harmful molecules in heart cells, allowing fat-burning enzymes to work better and move more fat into mitochondria for energy production.
What the research says
1 studyIn older male mice, a special diet with GlyNAC made two heart enzymes that help burn fat much more active — by over 80% — but the same diet did nothing for older female mice. The study directly measured this and found exactly what the claim says.
