Show Up Every Day
The hardest part of any supplement is remembering it. A gummy makes the daily habit almost automatic — which matters here, because HMB is studied as a consistent daily intake, not an occasional one.
Protein tells your muscle to build. HMB helps protect what you already have. These gummies pair both — leucine and its metabolite HMB — in a daily format you will actually finish the bottle of.

Benefits of HMB L-Leucine Gummies
-
Lean Muscle Maintenance
Muscle is always being built and always being broken down. Most supplement routines only address the building side. HMB is studied for the other side — helping protect the muscle you already worked for.
- Supports lean muscle maintenance
- Works on muscle protein breakdown
- Daily support, training day or not
-
Recovery Support
Hard sessions create damage you have to recover from before the next one counts. HMB has been studied for its role in supporting recovery and reducing exercise-induced muscle damage markers.
- Supports post-training recovery
- Studied in trained and untrained adults
- Best taken consistently, not occasionally
-
A Routine You Keep
The best-formulated supplement in your cupboard does nothing. Gummies remove the friction — no water, no shaker, no six-capsule morning — which is why adherence is the quiet advantage of this format.
- No water or shaker needed
- Travel and gym-bag friendly
- Easy to take every single day
What’s Actually In It
HMB (beta-hydroxy beta-methylbutyrate) is a metabolite of leucine. Research summarized by the International Society of Sports Nutrition describes a dual action: supporting muscle protein synthesis and suppressing muscle protein breakdown. It is the compound most people in the muscle-retention conversation have never heard of.
Leucine is the essential amino acid that acts as the trigger for muscle protein synthesis. It is why protein quality matters, not just protein quantity — and it is the precursor your body converts into HMB.
1,000 HMB mg and L-Leucine mg per serving, plus HMB form (calcium HMB vs free acid). Then state the daily total plainly — for this category, the number is the argument.]
Quality you can trust. Boscent products undergo independent third-party laboratory testing to help verify quality, purity, and consistency. We hold every product to rigorous quality standards so you can feel confident about what’s inside every bottle.

Train and Recover
With training consistent and recovery supported, the work compounds. This is the window where sessions start stacking instead of cancelling each other out — and where the recovery debt from a hard week stops carrying into the next one.
Daily for 3 Months
Lean Muscle, Maintained
Over a full training block, consistent daily use supports lean muscle maintenance and recovery — the payoff of a routine you actually stuck to.
The Evidence Behind It
Expert-Formulated
Developed alongside qualified experts and grounded in published research.
Researched Compounds
HMB and leucine are not novelty ingredients. Both have been studied in controlled human trials across trained and untrained populations for their roles in muscle protein turnover.
Third-Party Tested
Every production run goes to an independent laboratory for identity, potency and contaminant testing before release.

Frequently Asked Questions
Need Help? We're Here.
Protein and leucine drive the building side of muscle turnover. HMB is studied for the other side — helping suppress muscle protein breakdown. Most people cover one half of that equation and assume they have covered both.
Adults who want to hold onto lean muscle — whether you lift four times a week, are eating in a deficit, or are simply past the age where muscle maintains itself. It is not a pre-workout and not a stimulant.
Take 3 gummies daily before your workout. Take them on rest days too — the research on HMB is built on consistent daily intake, not workout-day-only use.
these are sugar-free. The chew comes from pectin, a plant-based fruit fibre, rather than gelatin, so they suit vegetarians and vegans too. Most muscle gummies carry several grams of added sugar per serving. That was the trade we weren't willing to make.
HMB and leucine are commonly used alongside protein and creatine, and they are well tolerated by most healthy adults. If you take prescription medication or have a medical condition, check with a qualified healthcare professional before adding anything new.
