NB HMB is a scientifically validated supplement that can enhance athletic performance. It contains beta-hydroxy beta-methylbutyrate (HMB), a leucine metabolite with both anti-catabolic and anabolic properties. HMB can help reduce muscle protein breakdown and stimulate muscle protein synthesis, leading to faster strength gains, increased lean muscle mass, and improved muscle recovery. The International Society of Sports Nutrition has confirmed these benefits in their recent position stand. HMB is effective for individuals of all ages and safe to take.


  • Boosts the growth of lean muscle mass
  • Reduces muscle breakdown
  • Increases protein synthesis

How does HMB Work?

HMB stabilizes muscle cell membranes, stimulates protein synthesis, and reduces protein breakdown. This is achieved by providing an alternate substrate for cholesterol synthesis, which is necessary for maintaining membrane integrity. HMB activates the mTOR pathway to increase muscle synthesis and influences protein degradation pathways to decrease muscle breakdown. By shifting the balance towards protein synthesis, HMB leads to net gains in muscle protein, resulting in greater strength gains and faster recovery.

How to take HMB?

The optimal dosage of HMB is 38 mg per kg or 17 mg per pound of body weight per day. A typical dosage is 3 grams per day for average-size individuals. Customize your dosage by following the simplified dosage scale based on your weight. Divide your daily dosage into 2-3 equal servings throughout the day rather than taking it all at once.
