The evidence in words
The verdict
For muscle (untrained / catabolic), HMB earns evidence grade C (small effect, mixed consistency) — the evidence is limited or mixed. Context-dependent
How it might work
It appears to reduce muscle-protein breakdown, which matters most when breakdown is high — detraining, illness, caloric deficit, or the untrained state.
How to use it
3 g/day, split; the free-acid form is absorbed faster.
Safety & cautions
Well tolerated.
Bottom line
Useful for the untrained, the elderly, and muscle-preservation during illness or dieting; skip it if you're a trained lifter hitting your protein.
How it is used
As the entry records it, from the studies it summarises. Not a recommendation for you — doses that suit a trial population may not suit you.
