β-Hydroxy β-Methylbutyrate, HMB

HMB is responsible for some of the beneficial effects of protein and leucine in the diet. It may be especially important for reducing the breakdown of muscle proteins. HMB is most effective for those who are getting started with exercise or increasing the intensity of their workouts.

What are HMB benefits?

HMB – short for β-hydroxy β-methylbutyrate – is a metabolite of the amino acid leucine, which reduces the breakdown of muscle proteins. Approximately 5% of dietary leucine is oxidized to HMB. In addition, it appears to be the main metabolite of leucine that most effectively prevents muscle protein breakdown. When compared to leucine, HMB appears to be significantly more potent on a gram-for-gram basis in attenuating the rate of muscle protein breakdown but is less effective than leucine in inducing muscle protein synthesis. Because of this, HMB is marketed as an anti-catabolic agent (aiming to reduce the rate of muscle degradation) rather than an anabolic agent (aiming to increase muscle mass). In view of this, according to scientific studies, the intake of HMB supplements is associated with certain benefits, such as increased exercise performance, reduced muscle degradation, and increased and supportive muscle growth in untrained and older adults.

Muscle Health HMB and Muscle Health

The muscles are responsible for body movement, stabilization, regulation of organs, substance transportation and production of heat in addition to being strongly associated with the circulatory and nervous systems. Muscle quality is essential for well being. Supplements that help keep muscles healthy are related to different factors, such as glucose and insulin regulation, protein synthesis, energy metabolism, and others.

  • Muscle Recovery

    When you exercise, you generate stress on your muscles and that damages the muscle fibers, causing them to break apart. During recovery the muscles need fuel to heal stronger than they were before, which will make them stronger.
