Macro partitioning

β-hydroxy β-methylbutyrate (HMB) supplementation (3 g/day) may help improve body composition in cancer patients, particularly those with smaller initial weight loss, by minimizing protein degradation.

HMB supplements (3g/day), often combined with arginine and glutamine, may help gain lean mass in cancer patients, especially those who haven't lost much weight yet. It may not be effective for patients with severe cachexia.

ModerateQualifiesMEDIUM confidence
A greater effect of the supplement was noted in patients with smaller initial weight loss (<5%), which suggests that some patients in the study might be in the refractory cachexia stage at which point nutrition interventions are unlikely to provide benefit.

Why this rating

Studies show mixed results, with some showing lean mass gain and others showing no difference, possibly due to short duration or patient selection.
