The Claim
HMB-free acid supplementation significantly increased plasma HMB concentrations in older men, confirming bioavailability and compliance, but this did not translate into measurable physiological benefits beyond a small increase in thigh lean mass.
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 HMB-free acid supplements raised levels of HMB in the blood of older men, showing the body absorbed it, but this did not lead to meaningful health improvements except for a minor gain in thigh muscle mass.

What the research says
1 studyThe study found that taking HMB-free acid helped older men gain a little more muscle in their thighs, but didn’t make them stronger or improve other functions more than exercise alone. So yes, it worked a little, but not much.
