Learn what HMB+ is, how it helps preserve muscle during cutting or maintenance phases, and whether it's right for your goals.
Quick answer
HMB+ is a leucine metabolite supplement that helps preserve lean muscle during calorie restriction or maintenance phases, making it valuable for athletes cutting weight or anyone wanting to protect hard-earned muscle.
Why muscle preservation matters more than building
During a calorie deficit, your body can break down muscle tissue for energy. HMB works by reducing muscle protein breakdown, which is especially useful when you're not in a surplus. This makes it a different tool from traditional mass-building supplements.
Who benefits most from HMB+
HMB+ is most effective for people who are actively dieting, maintaining weight, or coming back from a layoff. It's not a muscle builder on its own—it's a preservation aid. If you're in a bulk phase and gaining easily, you may not see dramatic results.
Decision rules for HMB+
- Are you in a calorie deficit?: If you're cutting, dieting, or maintaining weight, HMB+ helps reduce muscle breakdown. If you're in a calorie surplus, muscle preservation is less of a concern.
- Are you losing strength while dieting?: If your lifts are dropping, HMB+ may help preserve strength by supporting protein synthesis and reducing catabolism.
- Do you have a history of losing muscle during cuts?: If you've struggled to hold onto lean mass while losing fat, HMB+ is a targeted supplement for that specific problem.
Product facts
- HMB⁺: HMB is a metabolite of the amino acid leucine, and studies show supplementing at the correct dosage may improve strength while supporting increased lean muscle mass. This means HMB+ can help you keep strength and muscle even when calories are low, reducing the typical trade-off of dieting.
