Alkaline Water: The Health Hype Debunked?
Introduction: Alkaline Water – Hype or Health Miracle?
In the ever-changing world of health trends, alkaline water has made waves, promising benefits from improved hydration to better kidney health. But does it live up to the hype, or is it just another overpriced fad? A recent study from the University of California, Irvine, sheds light on its supposed benefits, especially for those at risk of kidney stones. Let’s break it down.
What Is Alkaline Water?
Alkaline water is marketed with a higher pH (8 to 10) compared to regular water (pH ~7), claiming to neutralize body acidity. Despite promises of better hydration, detox, and kidney health, often the "magic" is just clever marketing.
The Kidney Stone Connection
For those prone to uric acid or cystine kidney stones, raising urine pH can help prevent stone formation. Doctors prescribe potassium citrate, but large pills aren’t fun. Alkaline water seems a tasty alternative—if it actually works.
What the Study Found
Researchers tested five popular alkaline water brands (e.g., Smart Water Alkaline, Essentia). Although pH levels ranged from 9.69 to 10.15, the actual alkalinity was minimal (<1 mEq/L). Essentially, they’re just expensive tap water. Alternatives like baking soda or citrus juices deliver far more alkalizing power at a fraction of the cost.
Why It Matters
If you’re drinking alkaline water hoping for miracles, note this: Hydration is key—aim for at least 2.5 litres a day. Naturally alkalinize with fruits and vegetables, and use evidence-backed treatments like potassium citrate if kidney stones are a concern.

Final Thoughts
Alkaline water may look great on Instagram, but for real health benefits—especially preventing kidney stones—it’s more hype than help.
