Introduction

Broadly, from my experiences as a rugby player in the 1990s until 2004, the ubiquity of creatine saw a significant increase. It was and continues to be a common practice among athletes to boost their performance, and I, along with many of my team mates, used it significantly during this period. Throughout the past five years, I haven't heard reports of anyone facing renal issues due to the use of creatine, a natural and popularly consumed supplement.

The Myths and Realities

It is crucial to consider the notion that creatine, a natural supplement, may have caused severe health issues or contributed to the kidney failure of rugby icon, Jonah Lomu. Contrary to prevailing theories, the dominant narrative does not hold water in light of the available data and evidence.

Many insinuate that Polynesians possess a unique DNA strain that makes them more susceptible to adverse reactions when taking creatine, suggesting an inherent vulnerability. However, this argument lacks substantial scientific backing and should be re-evaluated in light of available medical and genetic research. Genetic predisposition towards renal problems in any population, including Polynesians, is multifaceted and not singularly attributed to creatine usage.

Health Issues and Medical Evidence

Jonah Lomu's health issues were primarily related to his kidney condition, nephrotic syndrome, a complex group of disorders that affect the kidneys. This condition leads to swelling and fluid retention, severe proteinuria (protein in the urine), and other related complications. The focus on creatine as the cause of his renal failure is misplaced and lacks direct evidence.

While it is essential to exercise caution and seek guidance from healthcare professionals when using dietary supplements like creatine, the specific health issues of athletes like Jonah Lomu do not provide a valid basis for linking creatine to his health problems. Compared to many other factors such as genetics, environmental influences, and lifestyle choices, the involvement of creatine in the complex health issues faced by Jonah Lomu is inconclusive.

Conclusion

In conclusion, while creatine usage among athletes to enhance performance is a common practice, there is no direct evidence suggesting that it caused the renal failure of Jonah Lomu. The primary contributors to his health issues were directly linked to medical conditions like nephrotic syndrome and subsequent complications, rather than the use of creatine or a unique genetic disposition to adverse reactions. It is important to understand the nuanced nature of health issues faced by athletes and to prioritize evidence-based medical evidence and expert advice over speculations.
