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 have dubbed hydrogen water a "miracle drink."

But is hydrogen water safe for the kidneys? If so, can patients with chronic kidney disease or those undergoing dialysis use it as well?

In this blog, let's evaluate the safety of molecular hydrogen water for kidney health, based on 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. There are multiple ways to infuse hydrogen gas into water, either through electrolysis or using magnesium tablets. The process increases the concentration of hydrogen molecules in regular water, opening health potential.

Unlike traditional antioxidants, such as 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.

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 use of hydrogen water in treating certain health conditions, especially in patients with renal issues.

What Does the Science Say About Hydrogen Water and Kidney Health

Let's explore recent clinical studies and research that highlight 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.

1. Hydrogen Water and Microcirculation

Although limited, a few studies suggest that hydrogen water may improve 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.

2. 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 could emerge as a promising therapy to support dialysis.

3. 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 on peritoneal dialysis patients yields 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 on kidney health from consuming hydrogen water. In fact, hydrogen-rich water has shown significant benefits for renal health as a selective antioxidant. Additionally, by regulating cell signaling and immune response, hydrogen water may help 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.

• Although there are no known adverse drug interactions with hydrogen water, patients with underlying chronic conditions should still consult a healthcare provider before starting hydrogen water or its supplements.

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 doesn’t guarantee a treatment for kidney disease.
