View Certificate of Analysis

The ProHealth Advantage: While most muscle supplements only work with intense exercise, HMB (ß-Hydroxy ß-Methylbutyrate) is uniquely effective across all activity levels. Backed by clinical research, our formula helps preserve muscle mass and strength whether you're highly active or less mobile. This unmatched versatility makes HMB a trusted choice for maintaining muscle health as you age.^*1-4,7

• Redefining Muscle Health: Once known for sports nutrition, HMB has emerged as a powerful longevity nutrient, helping to preserve muscle mass—a key factor in maintaining mobility, independence, and youthful vitality as you age.^*1-4,6,7,11
• For Every Stage of Life: Whether you're engaging in regular exercise or facing periods of inactivity, HMB supports muscle retention across all activity levels.^*1-4,7-9,11
•  Bio-Identical Support: HMB is naturally produced in small amounts when your body breaks down leucine, an essential amino acid that regulates protein synthesis and helps maintain muscle integrity.^*1-3
•  20x Leucine Power: With only 5% of leucine converting to HMB in the body, supplementation delivers 20 times more HMB than your body can produce on its own—delivering targeted support for optimal muscle gains.^*10

HMB is no longer just for athletes—it's a breakthrough in longevity science. Recognized for its ability to combat age-related muscle loss, HMB helps preserve muscle tissue—a key factor in maintaining both quality and length of life.^{*1-6,11-12,17}

Modern sedentary lifestyles accelerate the natural decline of muscle mass, which begins as early as our 30s. Research shows that skeletal muscle decreases by 3–8% per decade, with the rate accelerating after age 60. Strength loss occurs even faster—at up to three times the rate of muscle loss—compromising mobility, stability, and daily function.^*18-20

However, multiple clinical studies show that calcium HMB can help restore youthful muscle strength and quality—even without resistance training. When combined with exercise, the benefits are even greater, enhancing body composition, muscle repair, performance, and recovery.^*1,3,7,11

Stay Strong for Life with HMB*

Defend Against Age-Related Muscle Loss^*1,3,11
Clinical studies confirm HMB’s powerful role in preserving muscle mass and strength, particularly in adults over 50. It supports muscle health through two key pathways:*^1-2

• Increasing Protein Synthesis – HMB activates the mTOR pathway, the central regulator of muscle growth, to drive protein production, support repair, and promote muscle maintenance and hypertrophy.^*12
• Reducing Muscle Breakdown – HMB helps modulate the ubiquitin-proteasome system, the primary pathway responsible for muscle protein degradation, to slow muscle loss and preserve strength.^*16

Boost Exercise Performance ^*7-8
Athletes understand the challenge: exercise-induced muscle damage can prolong recovery, hinder progress, and make each workout feel like a fresh start. HMB helps optimize muscle function and accelerate recovery, so you can bounce back faster and keep pushing forward.*

• Boost Strength and Power: HMB supports muscle growth, enhances strength and anaerobic performance, and helps maintain peak performance during periods of intense training and overreaching.^*4,7,21
• Optimize Recovery: HMB helps minimize muscle damage, promoting faster recovery after intense physical activity.^*8-9
• Improve Body Composition: HMB helps reduce abdominal fat when paired with resistance training and a balanced diet.^*1,4

20x the Power of Leucine*
Leucine, a powerful branched-chain amino acid (BCAA), is essential for muscle growth and repair. While it is known to convert into HMB, only approximately 5% of leucine naturally transforms into this vital compound.^*10

• On average, diets provide about 14g of leucine daily, translating to just 700mg of HMB —far below the therapeutic levels required for optimal muscle support. This is where supplementation becomes essential.^*22
• ProHealth HMB provides a clinically supported dosage in one serving, helping you achieve the optimal HMB intake to combat age-related muscle loss, and promote strength, recovery, and overall muscle health.*
