Does HMB help with performance?

Conclusion: Overall, although limited and requiring interpretation with utmost caution, current evidence indicates that HMB supplementation is beneficial for improving muscle mass and strength, but there is no evidence of a benefit on physical performance in patients with sarcopenia. In future, more well-designed HMB intervention trials should be conducted that include populations diagnosed with sarcopenia according to well-accepted clinical consensus.

Conclusion: Although limited, current evidence suggests that HMB supplementation has a beneficial effect on muscle mass and function in patients with cancer. Well-designed trials are needed to further explore the clinical benefit of HMB supplementation in this patient population.
