The Claim
In adult male Sprague-Dawley rats undergoing endurance exercise, vitamin C supplementation has no effect on DNA synthesis rates in skeletal muscle, and this lack of change indicates that vitamin C's suppression of mitochondrial protein synthesis is not mediated by reduced cell proliferation.
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 adult male Sprague-Dawley rats performing endurance exercise, vitamin C supplements do not change the rate of DNA synthesis in skeletal muscle, and this shows that vitamin C's reduction of mitochondrial protein synthesis is not caused by a decrease in cell division.
See the scientific wording
In adult male Sprague-Dawley rats, vitamin C supplementation during endurance exercise does not alter DNA synthesis rates in skeletal muscle, indicating that its suppression of mitochondrial protein synthesis is not due to reduced cell proliferation.
When a rat runs, its muscles produce molecules called ROS that signal the cell to make more energy-producing parts. Vitamin C removes these ROS signals, so the muscle stops making new energy parts, but it doesn't stop making new muscle cells. The number of muscle cells stays the same, but the energy parts inside them don't get renewed.
What the research says
1 studyStudy: Differential effects of vitamin C or protandim on skeletal muscle adaptation to exercise.
In running rats, vitamin C lowered the production of mitochondrial proteins but didn’t change how often muscle cells divided, meaning it affects how cells maintain their energy factories, not how many cells they make.
