Creatine supplementation is facing a fresh wave of scrutiny, challenging its long-standing reputation. In a groundbreaking study led by Greg Nuckols, the very foundation of what we thought we knew about Creatine Monohydrate is being shaken.
Here's what we'll be covering in this article
New Research on Creatine
Creatine is a well-studied fitness supplement, but science is always changing. Back when lifting weights was seen as super healthy, everyone believed it without a doubt. Now, a recent study is questioning what we thought we knew about how much Creatine Monohydrate helps build muscles.
Deconstructing Lean Body Mass
Central to this challenge is the measurement tool widely used in past Creatine studies – lean body mass. A seemingly straightforward metric, lean body mass accounts for all body mass except fat. However, the caveat lies in its inability to distinguish between muscle and water. Creatine, known for increasing water retention, throws a curveball into this measurement, potentially leading to an overestimation of muscle gains.
Enter the new research spearheaded by Nuckols, focusing on evidence that employs direct imaging tools like ultrasound scans instead of relying on lean body mass. Ten relevant studies were scrutinized, revealing an estimated standard effect size of 0.11. Classified as “trivial to small,” this challenges the conventional excitement surrounding Creatine’s muscle-building prowess.

Non-Responders and Fitness Expert Insights
Before consigning Creatine Monohydrate to the skeptics’ corner, consider the existence of Creatine Monohydrate “non-responders.” Approximately 20 to 30% of individuals may experience minimal effects due to factors such as naturally high Creatine levels or unfavorable muscle fiber compositions. Renowned fitness expert Greg Nuckols contests the characterization of the effect as “trivial to small,” proposing a nuanced understanding based on hypertrophy-adjusted effect size classifications.
Rethinking Effect Size Classifications
Nuckols challenges the standard effect size classifications, suggesting a need for context in interpreting fitness research data. He introduces a hypertrophy-adjusted effect size chart, positioning an effect size of 0.11 within the realm of small to medium, aligning more closely with traditional beliefs about Creatine’s impact on muscle growth.
What Does This Mean for Creatine Fans ?
In the grand scheme, the implications for Creatine Monohydrate may not be revolutionary, but they are worth pondering. While this study may slightly nudge creatine’s effectiveness downward, it remains a stalwart supplement, offering consistent, albeit moderate, benefits. Despite this nuanced reassessment, creatine’s reputation endures, standing as a reliable choice for fitness enthusiasts.
In conclusion, this new study prompts a reevaluation of creatine’s muscle-building prowess. It challenges us to consider the intricacies of effect sizes, individual responsiveness, and the reliability of measurement tools. While the verdict may not drastically alter our perceptions of Creatine Monohydrate, it invites a thoughtful reflection on the nuances of its impact.
As you navigate your fitness journey, perhaps with a tub of Creatine in hand, remember that the debate continues, and science is an ever-evolving narrative. Stay informed, stay fit, and don’t forget to get your protein !
