The Claim
In older men undergoing resistance training, supplementation with HMB-free acid does not significantly enhance muscle strength gains, muscle thickness, or maximal voluntary contraction compared to placebo over a six-week period, and any small increase in lean mass does not translate to measurable functional improvements.
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 older men doing strength training, taking HMB-free acid supplements for six weeks did not lead to measurable improvements in strength, muscle size, or maximum force production compared to a placebo, even if there was a slight increase in lean mass.
See the scientific wording
In older men undergoing resistance training, HMB-free acid supplementation did not significantly enhance muscle strength gains, muscle thickness, or maximal voluntary contraction compared to placebo, indicating that any small increase in lean mass does not translate to measurable functional improvements within six weeks.
What the research says
1 studyIn older men who lifted weights, taking HMB didn’t make them stronger or their muscles thicker than those who took a placebo—even though their body fat decreased a bit more. So, more muscle mass didn’t mean better strength or performance in just six weeks.
