Introduction

Creatine (methylguanidine-acetic acid) is a compound synthesized endogenously in the liver, kidneys, and pancreas from amino acids such as arginine, glycine, and methionine. It is also obtained exogenously through dietary sources like red meat and fish. Approximately 95% of the body’s creatine is stored in skeletal muscle, where it plays a critical role in the rapid regeneration of adenosine triphosphate (ATP), the primary energy currency for short-duration, high-intensity activities (Kreider et al., 2017).

Since the 1990s, creatine monohydrate has emerged as one of the most popular and well-researched ergogenic aids in sports nutrition. Its supplementation is widely recognized for enhancing strength, power, and muscle mass, particularly in activities reliant on the phosphagen energy system (e.g., sprinting, weightlifting, and football). Beyond athletic performance, creatine has garnered attention for its potential neuroprotective, cognitive, and therapeutic benefits, including applications in neurodegenerative diseases, depression, and aging (Roschel et al., 2021).

This observational study aims to provide a contemporary snapshot of creatine supplementation in 2024, analyzing real-world usage patterns, user demographics, performance outcomes, and health perceptions. By synthesizing data from surveys, fitness communities, and clinical observations, this article offers insights into the evolving role of creatine in both sports and general health.

Discussion

1. Efficacy in Athletic Performance

The observational data align with existing literature, confirming creatine’s efficacy in enhancing high-intensity exercise performance. The improvements in strength, power, and muscle mass reported by users are consistent with meta-analyses demonstrating 5–15% increases in performance in activities reliant on the phosphagen system (Lanhers et al., 2017). The lack of significant benefits for endurance performance (reported by only 30% of users) is also supported by research, as creatine’s primary role is in short-duration, maximal-effort activities rather than aerobic metabolism.

2. Safety and Health Implications

The safety profile of creatine observed in 2024 remains consistent with scientific consensus. The most common side effect—water retention—is a well-documented and benign physiological response to increased intramuscular creatine stores. Concerns about kidney damage, dehydration, and hair loss were largely unfounded in healthy populations, though individuals with pre-existing renal conditions should exercise caution.

The potential cognitive and neuroprotective benefits of creatine, particularly among older adults, warrant further investigation. Observational reports of improved mental clarity and joint health align with emerging research on creatine’s role in brain energy metabolism and bone density (Dolan et al., 2019).

3. Demographic Trends and Gaps

The gender disparity in creatine use (72% male vs. 28% female) reflects broader trends in sports supplementation, where women are often underrepresented in both research and real-world adoption. This gap may stem from misconceptions about creatine causing "bulking" or masculinity, despite evidence showing similar ergogenic benefits for women (Tarnopolsky, 2000).

The increasing use of creatine among older adults (12% of users) is a promising trend, given its potential to mitigate age-related muscle loss (sarcopenia) and cognitive decline. However, targeted education is needed to address barriers such as perceived irrelevance or safety concerns in this population.

4. Supplementation Practices and Optimization

The dominance of creatine monohydrate (92% of users) underscores its status as the gold standard, supported by decades of research. Alternative forms (e.g., hydrochloride, buffered) did not demonstrate superior efficacy in observational data, suggesting that marketing claims may outweigh scientific evidence.

The loading phase, while common (58% of users), did not appear to confer significant advantages over steady-state dosing in real-world settings. This aligns with research suggesting that both methods achieve similar muscle saturation levels within 3–4 weeks (Hultman et al., 1996).

5. Addressing Misinformation

Persistent myths about creatine (e.g., steroid equivalence, hair loss, kidney damage) highlight the need for improved public education. Fitness professionals, healthcare providers, and supplement retailers play a critical role in disseminating accurate information. Social media and online forums, while valuable for community engagement, can also perpetuate misinformation, necessitating evidence-based counter-narratives.

Conclusion

Observational data from 2024 reaffirm creatine as a safe, effective, and widely adopted supplement for enhancing athletic performance and supporting overall health. Its benefits in strength, power, and muscle mass are well-supported by both real-world usage and scientific research, while its potential cognitive and therapeutic applications continue to emerge. Despite its proven efficacy, misconceptions and demographic gaps persist, underscoring the need for targeted education and further research.

Future observational studies should explore:

1. The long-term health effects of creatine in diverse populations, including older adults and individuals with metabolic conditions.
2. 
   
3. Strategies to increase creatine adoption among underrepresented groups, such as women and endurance athletes.
4. 
   
5. The impact of creatine on mental health and cognitive function, particularly in aging populations.
6. 
   
7. The role of digital platforms in shaping supplementation behaviors and combating misinformation.
8. 
   
9. 
   

As creatine supplementation continues to evolve, its integration into both athletic and clinical settings holds promise for improving human performance and well-being across the lifespan.
