HMB, or beta-Hydroxy beta-methylbutyrate, has earned a lot of attention in recent years for its reputation to improve recovery, increase muscle protein synthesis, and decrease muscle protein breakdown.
It's been a popular supplement for most of the last decade for these reasons, but for most of that time, there was only one type of HMB: HMB-Ca, which came in the form of a calcium salt. In recent years, a new version, HMB-FA or "free acid" has been promising even greater results.
So, what does the science say? Let's investigate.
What does HMB do?
HMB has been shown in studies to stimulate muscle protein synthesis by sparking an increase in anabolic signaling through the mTOR pathway, and inhibit muscle protein breakdown by blunting catabolic signaling within the ubiquitin-proteasome pathway. Evidence also suggests that HMB promotes other benefits, such as reducing markers of muscle damage, which may enhance recovery from high-intensity workouts.[1]
HMB is a metabolite of the amino...
