Is Hydrogen Water Safe for Kidneys? The Science Behind 

Hydrogen water, the latest trend in health and wellness, has gained significant attention for its incredible health potential, particularly in selectively neutralizing reactive oxygen species (ROS) and combating oxidative stress. In fact, many scientists and researchers dubbed hydrogen water a ‘miracle drink’.   

But is hydrogen water safe for kidneys? If so, can patients suffering from chronic kidney diseases or those undergoing dialysis use it as well? 

Here in this blog, let’s evaluate the safety of molecular hydrogen water for kidney health, backed by current scientific research. 

What is the Meaning of Hydrogen Water 

Hydrogen water is just regular water infused with molecular hydrogen (H₂), a gas known for its ‘selective antioxidant’ properties. The popular ways of making this water are effervescent hydrogen water pills, and hydrogen water bottles. Unlike traditional antioxidants, like vitamin C, hydrogen water can selectively neutralize harmful free radicals like hydroxyl (•OH) and peroxynitrite (ONOO−) without affecting beneficial ones. Additionally, it regulates endogenous antioxidants, including Glutathione (GSH), Catalase (CAT), and Superoxide dismutase (SOD). Therefore, hydrogen water contributes to a balanced oxidative stress response or redox homeostasis. 

Is hydrogen water safe for kidneys? To understand this, let’s first learn the impact of oxidative stress on kidney diseases. 

Kidney Disease and Oxidative Stress: Is There Any Link? 

Your kidneys filter about 50 gallons of blood every day, functioning as an important excretory organ. You might be surprised to find out that worldwide, about 850 million people suffer from kidney disease. Out of these 850 million, 10% of the population is severely affected by chronic kidney disease (CKD), resulting in around 1.2 million deaths annually. 

What’s worse? Oxidative stress is the primary key factor responsible for kidney damage. When left unnoticed for a long time, it can lead to inflammation and fibrosis and may even turn fatal. For a patient already struggling with a kidney condition, oxidative stress can further increase the health risk through continuous inflammation and cellular damage. 

Recent research highlights the application of hydrogen water in treating certain health diseases, especially in patients with renal conditions. 

What Does the Science Say About Hydrogen Water and Kidney Health 

Let’s explore the recent clinical studies and research highlighting the impact of hydrogen water on kidney function. 

Animal-Based Studies 

In a rat-based study model, hydrogen water significantly benefited kidney health. In rats with acute kidney injury, hydrogen-rich solution reduced inflammation, regulated oxidative stress, and even improved kidney function markers. However, larger human-based studies are still needed to confirm hydrogen water’s potential proactive role in renal health. 

Human-Based Studies 

Here is key human-based evidence highlighting the role of hydrogen water in renal health. 

Hydrogen Water and Microcirculation 

Though limited, a few studies show that hydrogen water may enhance microcirculation. Microcirculation is a biological process responsible for delivering oxygen and nutrients to tissues and releasing waste products. It includes a well-defined network of arterioles, capillaries, and venules. Therefore, by enhancing microcirculation, hydrogen water may help maintain fluid balance and blood pressure. 

Hydrogen Water and Hemodialysis 

Hemodialysis is a life-saving treatment for kidney failure. About 2 million people undergo hemodialysis each year, in which an artificial machine replaces the kidney’s filtering function. A 2010-published study shows that hydrogen-rich dialysis fluid can reduce inflammation and oxidative stress markers in hemodialysis patients. 

Another version of the same study highlights that hydrogen-rich dialysate reduces the medical risks in patients compared to those using standard dialysis fluids. The observation suggests that hydrogen water can emerge as a promising therapy supporting dialysis. 

Hydrogen Water and Peritoneal Dialysis 

Peritoneal dialysis is another popular treatment that about 11% of dialysis patients undergo each year. The medical procedure uses your abdominal lining as a natural filter to release excess fluid and waste.  

Research exploring the effects of hydrogen-rich water in peritoneal dialysis patients comes with interesting findings. It suggests that hydrogen-infused water can reduce peritoneal inflammation. The solution has shown a protective impact on the peritoneal membrane, improving dialysis outcomes. 

Is Hydrogen Water Safe for Kidney Patients? 

For patients struggling with renal health conditions, hydrogen water is generally safe. Based on current research, there are no significant adverse effects of hydrogen water consumption on kidney health. In fact, hydrogen-rich water has shown significant renal health benefits as a selective antioxidant. Additionally, by regulating cell signaling and immune response, hydrogen water may help to manage chronic inflammation. It has also improved patient outcomes in dialysis cases. However, here are a few medical considerations: 

• In dialysis cases, patients must carefully monitor their fluid intake. Even hydrogen water should be consumed within limits. Excess consumption can lead to medical complications. 
• Though there are no known adverse drug interactions of hydrogen water, patients with underlying chronic conditions must still consider a healthcare provider before starting hydrogen water or its supplements. 

Talking about supplements learn more about molecular hydrogen water tablets. 

Final Takeaway: Is hydrogen water good for kidneys? 

Based on current research and studies, the safety of hydrogen water in renal health is unquestioned. With consideration, hydrogen water supplements may improve dialysis outcomes and mitigate oxidative stress-related kidney damage. However, the results are still preliminary and require larger-scale clinical trials. Therefore, though safe for the kidneys, hydrogen water shouldn’t be promoted as a guaranteed treatment for kidney disease.
