The Science

The science

HMB is one of the most studied muscle-support ingredients available — backed by 50+ peer-reviewed studies and more than 30 years of clinical research.

Over 50 peer-reviewed studies. More than 30 years of clinical research. This is what the science says — in plain language. 

What is HMB

Beta-hydroxy beta-methylbutyrate.
Your body already makes it.

HMB is a naturally occurring compound produced when your body metabolizes leucine — an essential amino acid found in protein-rich foods. But here's the key: you can't eat enough protein to produce a meaningful amount of HMB. Even a very high-protein diet yields only about 0.2–0.4g of HMB per day. Research consistently shows that 3g per day is where the muscle-protective benefits appear.

01
Reduces muscle protein breakdown
HMB helps slow the process by which your body breaks down muscle tissue — particularly during periods of caloric restriction, illness, inactivity, or simply getting older. It does this by disrupting the cellular pathways that signal muscle degradation.
02
Supports muscle protein synthesis
HMB also activates pathways involved in building new muscle protein. It works alongside resistance exercise to improve the efficiency of your body's natural muscle-building processes — so the effort you put in goes further.

What the research shows
In controlled clinical studies, HMB supplementation at 3g/day has been associated with preserved lean muscle mass during caloric restriction, improved strength and functional performance in older adults, reduced muscle damage markers following intense exercise, and research suggests meaningful muscle retention even in the absence of structured exercise, based on studies in elderly populations.

Not all HMB is created equal.
We use the best.

myHMB® is the branded, clinically validated form of HMB produced by TSI Group — the same ingredient used in the majority of peer-reviewed HMB research. It is USP verified for purity and potency, meaning what's on the label is what's in the chew.

Science without
the supplement-label hype.

We make one thing. We put the clinically studied dose in a form people will actually take. We don't overclaim, we don't use proprietary blends, and we don't hide behind marketing language.
