Muscle Function
Muscle Health & Physical Energy
When it comes to aging, most people focus on maintaining muscle mass—but muscle function is equally important. Carnosine supports not only muscle size, but also the way muscles perform. By buffering pH, reducing fatigue, and supporting recovery, carnosine helps sustain muscle performance and mobility in daily life.
Muscle carnosine levels decline significantly with age—by as much as 47% in some populations. This reduction is associated with decreased buffering capacity, earlier onset of fatigue, and reduced physical function. β-alanine supplementation has been shown to help restore muscle carnosine levels, supporting physical performance and endurance.
Key Findings
- Older adults supplementing with β-alanine have demonstrated improvements in sit-to-stand performance, grip strength, and muscle endurance.
- Clinical research shows increases in physical capacity across a range of age groups and activity levels.
- β-alanine is recognized by organizations including the ISSN, NIH, and IOC as a performance-supporting nutrient.
Mechanisms of Action
Intracellular pH buffering
Helps maintain muscle pH during physical exertion.
Fatigue resistance
Supports sustained muscular performance and delays fatigue onset.
Functional aging support
Associated with improvements in strength, balance, and mobility in older adults.
