Is alkaline water the miracle drink it’s hyped up to be, or just another wellness trend wrapped in fancy marketing? If you’ve ever found yourself wondering, “Is alkaline water good for me?”, you’re not alone. Some swear by its health benefits, from better hydration to neutralizing acidity, while others argue it’s just glorified H2O.
So, what’s the truth? Let’s break it all down—the benefits, the risks, the myths, and whether you should be stocking up on high pH water (Harvard Health).
What Is Alkaline Water?
Alkaline water is simply water with a pH level higher than 7, making it less acidic than regular tap water. The alkalinity comes from minerals like calcium, potassium, and magnesium. But not all alkalised water is created equal.
- Natural alkaline water comes from springs and picks up minerals from rocks along the way.
- Ionized alkaline water is artificially altered using an ionization process.
- Kangen water, a type of ionized water, is marketed for its supposed health perks—but is it worth the hype?
- Medical grade alkaline water is sometimes promoted as an advanced form of ionised water, but its effectiveness is debated.

The Science Behind Alkaline Water Benefits
There are plenty of claims surrounding the benefits of drinking alkaline water, but what does science actually say?
Claim 1: May Help with Acid Reflux
One of the most popular claims is that alkaline water neutralizes stomach acid, making it helpful for those struggling with acid reflux. Some studies suggest that high pH water can deactivate pepsin, the enzyme responsible for acid reflux (Healthline). But does alkaline water help with acid reflux long-term? The research is still limited.
Claim 2: Potentially Supports Bone Health
Some believe that drinking alkaline mineral water can reduce bone loss by improving calcium absorption. However, medical professionals argue that diet and lifestyle play a bigger role in bone health than the water you drink (Mayo Clinic).
Claim 3: Improved Hydration & Exercise Recovery
Athletes swear by alkaline ionized water for hydration, claiming it helps with blood viscosity, which could mean better oxygen delivery to muscles. Some studies show slight improvements, but the difference may not be significant enough to justify the price tag. 11.5 pH water, for example, is often promoted for extreme hydration, but is it better than regular pH 7 water? Not necessarily.
Claim 4: Detoxification and Antioxidant Properties
Does alkaline water remove toxins from your body? Not exactly. Your liver and kidneys already do a fantastic job of detoxifying. That said, some antioxidant water benefits may stem from ionized alkaline water’s ability to combat oxidative stress.
Antioxidants found in alkaline drinks may help neutralize free radicals, but the best sources of antioxidants still come from whole foods like fruits and vegetables.
Claim 5: Anti-Aging and Disease Prevention
Marketers often link alkaline water benefits and risks to longevity. Claims include better digestion, reduced inflammation, and even cancer prevention. While a healthy pH balance is beneficial, the evidence supporting alkaline water’s role in disease prevention is still up for debate (Arthritis Foundation).
Alkaline Water vs Regular Water – Which Is Better?
When comparing alkaline water vs regular water, it really comes down to personal preference. Regular water is perfectly fine for hydration, and for most people, a balanced diet provides all the minerals needed.
That said, if you enjoy the taste and feel better drinking alkaline water at home, go for it! Some people also claim that drinking mineral water side effects can include bloating or stomach discomfort due to high mineral content.

Are There Any Risks of Drinking Alkaline Water?
While alkaline water benefits get plenty of hype, there are some risks to be aware of:
- Digestive issues: Drinking too much high pH water can reduce stomach acidity, making digestion less efficient.
- Kidney problems: If you have kidney disease, high mineral content in alkaline water could cause complications (Mayo Clinic).
- Electrolyte imbalance: Overconsumption of alkalising water might disrupt your body’s natural mineral balance.
- Kangen water side effects: Overuse can cause excess alkalinity in the body, potentially leading to nausea or confusion.
So, can you drink alkaline water every day? Yes, in moderation. But if you’re wondering, “Is alkaline water good for kidneys?”, it’s best to consult a doctor first.
How to Get Alkaline Water (Without Overspending)
If you’re convinced and want to try it, here’s how to get alkaline water:
- Buy bottled alkaline water (look for brands with added minerals).
- Use a Kangen water machine (be mindful of Kangen water side effects and costs).
- Try alkaline drops to enhance your tap water.
- Make your own: How to make alkaline water at home? Add a pinch of baking soda or squeeze some lemon into your water.
The Verdict – Should You Start Drinking Alkaline Water?
If you’ve ever thought, “I drink alkaline water for a month, will I feel different?”, the answer is: maybe. Some people report better hydration and digestion, while others don’t notice a difference. The positives and negatives of ionized water will depend on your individual health and hydration needs.
So, is alkaline water a gimmick? Not entirely. There are some benefits, but they’re often overstated. The best approach? Stay hydrated—whether it’s regular, ionised, or alkalised water.
FAQs About Alkaline Water
Does alkaline water really work?
It may offer some hydration benefits, but claims of disease prevention aren’t well-supported.
Is alkaline water bad for you?
Not necessarily, but overconsumption may lead to digestive or kidney issues.
How much alkaline water should I drink a day?
A balanced amount (1-2 litres) should be fine for most people.
Can kids drink alkaline water?
Yes, but it’s not necessary unless advised by a doctor.
What are the disadvantages of Kangen water?
The cost, exaggerated health claims, and potential mineral imbalances.
How to make water alkaline naturally?
