The Claim
Whey protein supplementation does not enhance the effects of resistance exercise on muscle strength, fat-free mass, physical function, or inflammatory biomarkers in healthy active older men aged 67 years.
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 healthy active men aged 67, taking whey protein in addition to resistance exercise does not lead to greater improvements in muscle strength, fat-free mass, physical function, or levels of inflammatory biomarkers compared to resistance exercise alone.
See the scientific wording
Whey protein supplementation does not enhance the effects of resistance exercise on muscle strength, fat-free mass, physical function, or inflammatory biomarkers in healthy active older men aged 67 years.
When older men lift weights, the force on their muscles triggers signals that build more muscle protein and reduce body-wide inflammation. This makes them stronger and improves their immune balance. Adding whey protein does not make them stronger or gain more muscle, but it does help them walk faster by improving how well their muscles use protein to function better, even without changing muscle size.
What the research says
1 studyAdding whey protein to weight training didn't make older men stronger, gain more muscle, walk farther, or reduce inflammation any more than weight training alone. The protein only helped them walk a tiny bit faster on its own.
