The study and its comparison

NOURISH randomized 652 malnourished hospitalized adults aged at least 65 to standard care plus a high-protein HMB-containing oral formula or placebo supplement. Selected cardiac or respiratory admissions were included. [1]

At ninety days after discharge, the primary composite and readmission rates did not significantly differ. Mortality was 4.8 percent versus 9.7 percent, a favorable secondary result; nutritional status also improved. [1]

What the finding establishes

This was a multinutrient intervention, so its effects cannot be assigned to HMB alone or another product such as Juven. Authors included Abbott Nutrition employees; complete funding and conflicts were not established from the abstract. The selected hospitalized population differs from healthy gym users. [1]

A hypothetical distinction

Imagine a formula includes protein, energy and HMB. The trial cannot identify which component caused a difference.
