Who it may plausibly help - and who it won’t magically fix
- Potentially older adults with inadequate protein (clinical context)
If your situation isn’t represented here, that doesn’t prove uselessness - it means our file doesn’t claim a narrow benefit for you without better evidence.
Trials
What the science suggests
Mixed meta-analytic outcomes; publication bias concerns have been discussed in reviews.
Gap analysis
Typical promises vs trial reality
Gym marketing implies guaranteed gains; trial heterogeneity contradicts a universal story.
Calibration
Hype vs reasonable expectations
Moderate-to-high relative to consistent trained-athlete proof.
Verdict snapshot
Studies conflict or are small; some plausible benefits, but the signal is too noisy for strong claims.
