The Claim
GlyNAC supplementation reverses age-related brain glucose steal by improving mitochondrial function in peripheral tissues, thereby increasing brain glucose utilization and enhancing cognitive performance in older adults.
What the research says
Not yet evaluated
We are still looking at what the research says.
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 adults, GlyNAC supplementation increases the amount of glucose the brain uses and improves cognitive performance by correcting reduced mitochondrial function in other tissues that otherwise limit glucose availability to the brain.
See the scientific wording
GlyNAC supplementation reverses age-related 'brain glucose steal'—a phenomenon where impaired mitochondrial function in peripheral tissues diverts glucose away from the brain—thereby improving brain glucose utilization and cognitive performance in older adults.
GlyNAC gives the body the building blocks to fix damaged energy factories in muscles and liver. When these factories work better, they stop hoarding glucose and start using fat for fuel instead. This frees up glucose in the blood so the brain can take in more of it, which lets brain cells make more energy and work better.
What the research says
1 studyTaking GlyNAC helped older adults' brains use more glucose, which may mean their brains got more fuel—just like the claim says. When they stopped taking it, the benefit went away.
