The Claim

In aged male mice, 12 weeks of GlyNAC supplementation increases Ndufb8 protein levels in heart mitochondria by 1.76-fold compared to unsupplemented controls.

In plain English

In older male mice, taking GlyNAC for 12 weeks results in a 1.76-fold higher level of the Ndufb8 protein in heart mitochondria compared to mice not taking GlyNAC.

See the scientific wording

In aged male mice, GlyNAC supplementation for 12 weeks is associated with a 1.76-fold increase in Ndufb8 protein levels in heart mitochondria compared to controls, suggesting a sex-specific enhancement of mitochondrial respiratory chain function.

Why this might work

GlyNAC provides the building blocks for glutathione, which clears harmful molecules in heart cells. This allows mitochondria to make more of a key protein called Ndufb8, which helps produce energy. At the same time, the heart starts using fat more efficiently for fuel, which supports stronger energy production and less stiffness in heart tissue.

    In older male mice, a special diet with GlyNAC made a key energy-producing protein in the heart 76% higher, but the same diet didn’t change anything in older female mice. This matches exactly what the claim says.
