Safety Parameters: Myalgia, Fatigue, and Enzyme Levels

When evaluating the safety profile of creatine supplementation, it is crucial to consider the potential for side effects such as myalgia and fatigue. Studies have shown that these symptoms can manifest in a dose-dependent manner, particularly at higher dosages. However, it is noteworthy that elevated levels of creatine kinase (CK), a marker of muscle damage, were not observed, suggesting that myalgia and fatigue are not indicative of muscular injury.

The absence of significant changes in serum enzyme levels, such as lactate dehydrogenase (LDH) and CK, further supports the safety of creatine, as these are critical biomarkers for assessing potential damage to the heart, skeletal muscles, and brain.

The following table summarizes the incidence of adverse events in a study comparing two dosage groups:

Dosage (mg) Myalgia (%) Fatigue (%) Nasal Congestion (%) Flushing (%)
30 0 0 20 30
60 50 20 20 0

Collagen, often used in conjunction with creatine, is known for its beneficial effects on connective tissues and may help mitigate some of the musculoskeletal complaints associated with intense physical activity. The safety parameters of creatine, when considered alongside its synergistic use with collagen, present a favorable profile for athletes and fitness enthusiasts.
