Best Fit Profiles
- deconditioning and recovery phases
Muscle preservation under stress and aging
HMB (Beta-Hydroxy Beta-Methylbutyrate)
Evidence supports preservation of lean mass and selected functional outcomes, especially when paired with resistance training.
Evidence Level B
Evidence and Risk Labels
Evidence A/B/C reflects research maturity, and risk levels reflect monitoring needs. These labels support comparison, not diagnosis or treatment decisions.

- Effect Size
- Modest lean-mass and functional-support benefit
- Safety
- Low Risk
Works best when paired with adequate protein intake and resistance exercise.
Research Dosing
This reflects common ranges and protocols used in published studies, not personal medical advice.
- Typical Daily Dose
- 3 g
- Timing
- Split into 2-3 doses with meals
- Protocol Duration in Studies
- 8-24 weeks in muscle-focused studies
Effect size is generally larger in less-trained and older populations.
