Alkaline water has become a wellness trend, praised by celebrities and health influencers alike. From promises of detoxification to improved metabolism, the claims sound impressive. But what exactly is alkaline water—and should you be drinking it?
Key Points:
- Alkaline water has a higher pH than regular water
- Some believe it neutralizes acidity in the body
- Scientific evidence on major health benefits is limited
- Overconsumption may cause health issues
What Is Alkaline Water?
Alkaline water typically has a pH between 8 and 9.5, compared to regular tap water, which is neutral at pH 7. It often contains added minerals such as calcium, potassium, and magnesium that raise the pH.
Water can be naturally alkaline (from mineral springs) or artificially made using ionizers. These machines split water molecules and claim to produce alkaline water with extra health benefits.
Potential Health Benefits Of Alkaline water
Some studies and anecdotal reports suggest alkaline water might offer the following:
1. Better Hydration
Alkaline water may be absorbed more quickly due to smaller “water clusters,” although this claim isn’t solidly backed by research.
2. Reduced Acid Reflux
One small study found that alkaline water with a pH of 8.8 helped deactivate pepsin, an enzyme linked to acid reflux.
3. Antioxidant Effects
Ionized alkaline water is often said to have antioxidant properties, which could neutralize harmful free radicals. However, more research is needed.
4. Bone Health
Some believe it helps reduce bone loss due to its mineral content, but studies are inconclusive or show minimal effect.
Is It Backed by Science?
Unfortunately, most of the bold claims are based on limited or weak evidence. The body already regulates its internal pH tightly through the lungs and kidneys. Drinking alkaline water won’t change your blood pH significantly.
According to the Mayo Clinic, there’s no strong scientific evidence that alkaline water has health benefits greater than those of regular water source.
Risks and Side Effects
While drinking a glass of alkaline water now and then is likely harmless, overconsumption can cause:
- Alkalosis – an overly alkaline body state, which can lead to nausea, vomiting, muscle twitching, or confusion
- Lowered stomach acidity – which may impair digestion and kill fewer harmful bacteria
- Electrolyte imbalance – especially if the water is ionized without proper mineral balance
Pregnant women, children, and people with kidney conditions should avoid regular intake without consulting a doctor.
Who Might Benefit?
- People with acid reflux may find relief from alkaline water with a pH of 8.8+
- Athletes looking for improved hydration might experiment with it, though data is limited
- Individuals with low-mineral diets may benefit from mineral-enriched alkaline water
But again, it should not replace a healthy, balanced diet and lifestyle.
What’s the Verdict?
Alkaline water isn’t a miracle cure—but it’s not snake oil either. If you like the taste or feel better after drinking it, there’s no harm in occasional use. Just don’t let it distract you from real health habits like:
- Eating whole, nutrient-rich foods
- Exercising regularly
- Managing stress
- Drinking enough water—alkaline or not
