The increasing interest in health and wellness has brought various new products into the spotlight, one of which is hydrogen water. Many people are curious about its potential benefits, especially concerning organ health. A common question that arises is whether hydrogen water can positively impact kidney function.
Understanding Hydrogen Water
Hydrogen water is regular drinking water infused with dissolved molecular hydrogen gas (H₂). This infusion typically occurs through electrolysis, or by adding magnesium sticks or tablets that react with water to release hydrogen gas. These H₂ molecules are proposed to exert biological effects.
The fundamental proposed mechanism of action for hydrogen water is its role as a selective antioxidant. Molecular hydrogen targets and neutralizes harmful reactive oxygen species, like hydroxyl radicals, without disrupting beneficial molecules. This selective action helps reduce oxidative stress.
Proposed Effects on Kidney Health
Hydrogen water is proposed to benefit kidneys through its antioxidant and anti-inflammatory properties. Oxidative stress, caused by harmful free radicals, can damage kidney tissue and contribute to kidney conditions. As a selective antioxidant, hydrogen water is hypothesized to reduce this damage.
The proposed benefits also include mitigating inflammation, a factor linked to chronic kidney disease (CKD). Hydrogen water may modulate inflammatory pathways and reduce pro-inflammatory cytokines, potentially protecting renal tissue. Animal studies have shown hydrogen can reduce kidney damage in models of acute kidney injury and CKD. These benefits suggest a protective role for kidney cells.
Current Research and Expert Views
Current research on hydrogen water and kidney health is preliminary. While animal studies show promising results, like reduced renal oxidative stress and improved kidney function markers, large-scale human clinical trials are lacking. Some small human trials, particularly involving dialysis patients, have reported reduced oxidative stress, inflammation markers, and improved kidney function indicators like blood urea nitrogen levels.
For example, a 2017 study indicated hydrogen-rich water lowered markers like C-reactive protein in dialysis patients. Patients consuming electrolyzed hydrogen-rich water before and after dialysis sessions also reported feeling more energetic and reduced fatigue. Despite these findings, experts emphasize that more robust, large-scale randomized controlled trials are needed before hydrogen water can be considered a medical treatment for kidney diseases.
Important Considerations for Kidney Patients
Individuals with pre-existing kidney conditions should consult healthcare professionals before incorporating hydrogen water into their routine. Hydrogen water is not a substitute for prescribed medications or conventional medical treatments for kidney diseases. Its long-term safety and efficacy, especially for those with compromised kidney function, are not yet well-established.
The quality of hydrogen water products can vary, with some potentially not producing enough molecular hydrogen to be effective. Molecular hydrogen gas can escape quickly, so timing and proper storage are important for maintaining its concentration. Professional medical guidance is recommended to ensure safety and to understand if hydrogen water could be a suitable complementary approach.
