THE ULTIMATE ANABOLIC

HMB (β-Hydroxy β-Methylbutyrate) is a metabolite of the amino acid Leucine and is one of the most effective natural anabolic compounds – both preventing the breakdown of muscle fibers while increasing protein synthesis. As a result, HMB supplementation may increase muscle recovery after intense exercise, boost muscle growth, and even enhance endurance while working out. While the human body does have a limited ability to convert Leucine to HMB, it’s thought that they only way to significantly increase blood HMB levels is through dietary supplementation.*

Prevent Muscle Death

Preserve Your Gains and Stay Anabolic Compared side-by-side to other amino acids, HMB has been shown to be significantly more effective at preserving muscle mass and offsetting muscle atrophy during diet and intense exercise for both males and females. As a central component of muscle cells, HMB also contributes to quicker recovery times and increased strength gains, as it enables athletes to train harder and adapt to their training more quickly.*

IMPROVE MUSCLE OUTPUT

Through a complex process called “the Ubiquitin pathway”, HMB can actually prevent the death of muscle cells while supplying them with more vital muscle building protein for repair and recovery.*6 By preserving existing muscle cells and promoting the growth of new cells, athletes of all kinds are better able to adapt to their training.2 This adaption and recovery process, known as the m-TOR pathway, means that endurance trained muscles may become more efficient and resistant to fatigue, while resistance trained muscles may increase in size and strength.2

In addition, all types of athletes have also been shown to experience reduced soreness, which further decreases recovery time and improves muscle output.7

THE ULTIMATE COMBINATION

While HMB can be highly effective when taken on its own, numerous studies suggest that combining it with BCAAs and/or Creatine produces far superior results than taking either product independently.*

Together, these supplements can provide vast improvements in strength, endurance, and appearance.* While generic supplements might provide adequate results, NutraKey ultra micronized formulas have been specially created for maximum bioavailability in the body – increasing the amount of each serving that’s actually absorbed and saving both the money in your wallet and time in the gym.
