Does HMB enhance body composition in trained individuals!? 💪

New data in trained and untrained individuals.

High-dose medium-term HMB supplementation did not trigger body composition changes in trained and untrained males under usual conditions or high-intensity functional exercise

Study Details

This new study recruited 90 participants (53 trained + 37 untrained) 🏋️

Participants were split by training status and within each group were assigned to take either…

1️⃣ HMB (90 mg/kg/day)

2️⃣ Placebo

…alone for 3-weeks, followed by another 3-week period combined with a training intervention 🗓️

Here is what they found ⬇️

Key Findings

💊 HMB doses ranged from 4.8 - 7.8 g/day

The intervention had no effect on…

❌ Body mass

❌ Fat-free mass

❌ Fat mass

❌ Total body water

There were some improvements in FFM (end of study vs baseline) but this was in the untrained group 📈

There were no differences between HMB or placebo 🚨

Conclusion

High dose HMB supplementation does not change body composition in trained or untrained individuals over a 3 - 6 week period ❌

HMB may require longer term supplementation to improve body composition, but will any minor improvement be worth the cost? 🧐
