Strength-Building Power, Backed by Science

Performance-driven athletes immerse themselves in highly intense training regimens to improve their strength, power, physique, and results. To ensure elite performance, competitive athletes need to optimize the time and effort invested in training. Reducing recovery time between workouts is critical to mapping out a strategic training schedule. Enter myHMB.

MyHMB, scientifically known as beta-hydroxy beta-methylbutyrate, is a natural metabolite of the BCAA leucine. It aids in increasing muscle protein by acting on both sides of the metabolic pathways of protein balance. MyHMB stimulates muscle protein synthesis through the mTOR pathway while simultaneously decreasing muscle protein breakdown by decreasing the ubiquitin-proteasome proteolytic pathway. With myHMB you will increase strength and power, improve body composition, and recover faster after intense training.

    “Within weeks of taking myHMB I had set multiple personal records in my Olympic lifts, over-head squat, front and back squat. I tell everyone that is in the quest for health, wellness, and better performance if you want to be a recovery monster you need to take myHMB.”

    "CrossFit is a very intense sport and can take a toll on your body. With myHMB, I have noticed a faster recovery time and less muscle soreness. MyHMB also aids in the production of muscle mass, taking myHMB along with proper training and healthy eating I am stronger and leaner than ever!"

    "Within a month of taking myHMB I set all time records in the snatch, front squat, and back squat. The greatest thing about myHMB is how it has improved my recovery. This has allowed me to incorporate more training sessions a week into my regimen, and the results have followed."

Improves Performance and Body Composition Response to Training

Studies have shown that supplementing with myHMB improves body composition by both increasing lean muscle gains and boosting body fat loss. In a 12-week study, participants supplementing with myHMB during strength training saw a 250% increase in lean mass gain compared to placebo-supplemented participants. They not only gained more lean muscle, but they also lost 210% more body fat than those on the placebo treatment.

Increases Strength When Combined with Training

Strength gains are maximized with the use of myHMB. A meta-analysis of resistance-exercise training studies shows that myHMB supplementation results in increased strength gain. The studies showed increases for trained and untrained, young and elderly, and men and women. While the magnitude of the effect varies with training intensity and population studied, the overall effect was clear — myHMB significantly increases strength gains when supplemented during resistance-exercise training.

Improves Body Composition During and After Calorie-Restricted Diets

Calorie restriction to reduce overall body weight can result in an unwanted loss of muscle mass. But supplementing with myHMB has been shown to prevent the loss of muscle mass during a calorie-restricted diet. Using an animal model to simulate the effects of caloric restriction, a study compared caloric restriction alone in combination with training or training plus myHMB. MyHMB prevented the loss of muscle mass and lessened the loss of grip strength with caloric restriction.

Reduces Muscle Soreness

“No pain, no gain.” We all know hard training goes hand-in-hand with muscle soreness after intense activity. But myHMB helps minimize muscle soreness by reducing muscle protein breakdown and improving muscle recovery. Trained athletes significantly improved their readiness for the next training session when starting an intense exercise program, or increasing training intensity (overreaching), as indicated by the Perceived Readiness Status (PRS) score. PRS is used to indicate fatigue and predicts improvements in the next training session. With myHMB, athletes can protect themselves from exercise-induced muscle damage, reduce muscle soreness, and come back ready to train or compete again more quickly.

Increases Anaerobic Capacity

Sprinting, strength training, and jumping sports—they all rely on anaerobic metabolism to create the power these high-intensity activities require. Anaerobic capacity determines how well the body can perform short-interval maximal work. In a study using the Wingate Anaerobic Test of peak power (one of the most well-known fitness tests), supplementation with myHMB resulted in a 54% increase in anaerobic power over training alone.
