The Claim
In older adults aged 65 and above, 12 to 24 weeks of protein supplementation with or without resistance exercise has no significant effect on bone mineral density at the spine or total body.
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.
Taking protein supplements for 12 to 24 weeks, with or without strength training, does not change bone mineral density in the spine or whole body in people aged 65 and older.
See the scientific wording
In older adults aged 65 and above, 12 to 24 weeks of protein supplementation with or without resistance exercise does not significantly improve bone mineral density at the spine or total body.
Even when older adults get more protein, their bone-forming cells don't increase their activity enough to build denser bone because the signals that trigger bone growth are too weak and the minerals needed to harden the bone don't get deposited properly.
What the research says
1 studyGiving older adults extra protein pills or shakes for up to 6 months didn’t make their bones any denser, even when they also did strength training. So, the idea that protein supplements improve bone density in this group isn’t backed by this study.
