The Claim
The effect of HMB supplementation on fat-free mass in athletes is limited to individuals consuming less than 1.6 grams of protein per kilogram of body weight per day, as indicated by subgroup analyses of studies with variable protein intake reporting.
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.
HMB, a supplement used by athletes, may only help increase fat-free mass in those who eat less than 1.6 grams of protein per kilogram of body weight each day. For athletes consuming more protein, HMB does not appear to provide additional benefit.
See the scientific wording
The potential benefit of HMB on fat-free mass in athletes appears to be limited to those consuming less than 1.6 grams of protein per kilogram of body weight per day, based on subgroup analysis of studies with variable protein intake reporting.
What the research says
1 studyStudy: Does HMB Enhance Body Composition in Athletes? A Systematic Review and Meta-analysis
This study found that HMB supplements might help athletes build muscle, but only if they aren’t eating enough protein. If they already eat plenty of protein, HMB doesn’t seem to help much.
