- SUPPORTS MUSCLE PRESERVATION: HMB, a metabolite of leucine, has been shown to slow the rate of skeletal muscle protein breakdown. This makes it especially valuable during periods of intense training or caloric deficit, helping preserve lean muscle mass.
- ENHANCES POWER OUTPUT: Research shows HMB supplementation can increase power output in both short-term and long-term training. By improving explosive strength, it supports higher performance in lifts, sprints, and other high-intensity movements.
- PROMOTES FASTER RECOVERY: HMB helps reduce muscle damage caused by strenuous exercise. This protective effect means less soreness, quicker recovery between sessions, and the ability to sustain a higher training frequency without sacrificing performance.
- ACTIVATES MUSCLE-BUILDING PATHWAYS: Through the mTOR-P13K pathway, HMB stimulates skeletal protein synthesis much like its parent compound, leucine. This promotes growth and adaptation, giving your muscles the support they need to thrive under heavy training loads.
- THE CRUSH IT LIFESTYLE: Core Nutritionals is committed to transparency and quality, with all products manufactured in the U.S. in cGMP facilities and backed by rigorous testing. Our mission is built on the CRUSH IT mentality— pursuing excellence, integrity, and helping others achieve their best both in and out of the gym.

HMB (?-hydroxy ?-methylbutyrate) is an endogenous metabolite of leucine, derived from its parent amino acid via two enzymatic conversion steps. In total, approximately 5% of consumed leucine by weight is converted to HMB. Once converted, HMB has been shown to possess several interesting effects. In cellular assays, HMB was shown to increase the rate of skeletal protein synthesis through the same mechanism as its parent compound, leucine, the very important mTOR-P13K pathway that regulates the majority of muscle protein synthesis in vivo. This mechanism has also translated into practical benefits for human muscle, as several trials have shown HMB to slow the rate of skeletal muscle breakdown, increase energy production in acute (short) and chronic (long-term) trials, as well as mitigate muscle damage during high-intensity exercise.
