Alkaline Water: Benefits, Side Effects, and More (Complete Guide)
Estimated Reading Time: 5 minutes
|We all know that water is the backbone of life! But have you ever heard of alkaline water, the latest health trend?
In 2013, Beyoncé, one of the greatest pop icons of the 21st century, was found drinking alkaline water backstage on her tour "Mrs. Carter Show." Not only that, Miranda Kerr, the Australian model, once mentioned in her interview, "I have alkaline water filters in my kitchen sink and shower heads." What are the health benefits of alkaline water that are gaining so much attention among elite personalities? Moreover, what's the science behind alkaline water? Is it safe for human consumption? Let's answer all these questions in the following blog.
Understanding the Science Behind Alkaline Water
The term "alkaline" refers to the basic nature of compounds that score above 7 on the pH scale, typically 8-9. Therefore, alkaline water is less acidic than regular tap water, which offers potential health benefits. It may alter the body's pH balance, reducing acid reflux. Although there is less evidence, alkaline water may treat liver disease and support weight loss.
Composition of Alkaline Water
Here are the composition and constituents of alkaline water, which define its higher pH and lower hydrogen concentration:
-
Natural Alkaline Minerals: Natural alkaline minerals, such as bicarbonate, calcium, magnesium, and potassium, constitute a significant percentage of alkaline water.
-
Electrolytes: When prepared on a commercial scale, alkaline water may also contain electrolytes, including sodium, silica, and bicarbonate, to promote body metabolism.
Is Alkaline Water Natural or Artificial
Alkaline water exists in both natural and commercial forms. Naturally, it occurs when a river or water flows over mineral rocks such as calcium and carbonate. On a commercial scale, electrolysis produces alkaline water, where an ionizer makes the water more acidic or alkaline.
There are also DIY methods to prepare alkaline water, such as adding lemon juice or baking soda. However, these methods aren't backed by quality research. Therefore, you should be careful when choosing alkaline water for consumption.
What Makes It Different from Regular Water
Unlike regular water (pH 6.5 to 7.5), alkaline water has a high hydrogen potential. However, its low hydrogen concentrations make it basic, standing at 8-9 on the pH scale.
Additionally, alkaline water has a negative oxidation-reduction potential, indicating its ability to act as an antioxidant. It can donate electrons, creating a reducing environment for other substances.
Let's see how these differences contribute to the health potential of alkaline water.
Possible Health Benefits of Alkaline Water
Why is alkaline water good for you? Let’s explore this in detail.
A few studies experimented with the health benefits of alkaline water. However, most of these studies are animal-based, which raises uncertainty and debates about their results.
-
Instant Hydration
Athletes and fitness enthusiasts often drink alkaline hydrogen water for instant hydration. Alkaline water can be absorbed quickly, showing instant hydration compared to regular water.
It is beneficial for individuals who face fatigue due to dehydration. Quick hydration supports natural detoxification pathways, which eliminate toxins from the body.
-
Regulate Acid Reflux
In the US, about 20-30% of adults are affected by Gastroesophageal reflux disease (GERD). GERD is a medical condition caused by the backflow of acid in the esophagus, leading to heartburn and gastrointestinal irritation.
Alkaline water with a pH of 8.8 neutralizes pepsin (a digestive enzyme responsible for GERD), providing relief from acid reflux symptoms. By decreasing stomach acidity, alkaline water also supports digestive metabolism.
-
Weight Loss
Globally, around 45-50% of people are actively trying to lose weight. Alkaline water may help lose weight but without any direct contribution. It supports metabolic rate, accelerating the fat decomposition process.
Additionally, with instant hydration, alkaline water may slow down unnecessary cravings, helping you achieve your ideal weight.

Bone Health
Despite the debate, drinking alkaline water may support bone health, which may be due to the presence of calcium and other minerals in the water. It strengthens bone mineral density, mitigating the risk of severe diseases such as osteoporosis.
Also, in a few trials, alkaline water has reduced inflammation and uric acid levels in Gout patients, promising definite potential.
Note: Only a few studies and research highlight the health benefits of alkaline water. Therefore, incorporating alkaline water as a treatment or cure against any infection or disease is still uncertain.
Hype Around Alkaline Water
Although there are a multitude of benefits, numerous rumors and myths associated with alkaline water create unnecessary hype. It's wiser to stay away from such myths, including:
-
Energy Levels
Many individuals report that drinking alkaline water can increase their energy levels. However, there is no way alkaline water gives you more energy than regular water. It may help you achieve quicker energy with instant hydration.
-
Slow Aging
Often, celebrities endorse alkaline water as an anti-aging drink. However, alkaline water has no direct effect on aging.
The only truth is that adequate hydration, which comes from regular water as well, helps fight chronic diseases, allowing individuals to live longer.
-
Skin Nourishment
Human skin has a slightly acidic pH, which protects it against harmful bacteria and helps balance natural oil production.
Alkaline water may disrupt the skin's balance, causing irritation rather than nourishment.
Side Effects of Alkaline Water: Is It Safe?
Drinking slightly alkaline water (pH 7.0 to 8.5) daily does not show any significant adverse effects. However, overdrinking may cause:
-
A decrease in vital gastric acids in the stomach affects digestion
-
Constant feeling of bloating or feeling tummy-full quickly
-
Kidney stones: Due to the presence of alkalizing minerals (calcium, bicarbonate, and potassium)
-
Due to limited studies and research, there is still no clear evidence justifying the severity or occurrence of these symptoms.
Should You Drink Alkaline Water or Try Better Alternatives
You may add alkaline water in limited amounts if you want. However, for effective results, it's best to opt for better alternatives, such as molecular hydrogen water. Molecular hydrogen acts as a selective antioxidant, neutralizing harmful free radicals and protecting the body from oxidative stress. Moreover, emerging research suggests that hydrogen-enriched water may help recover muscle fatigue and improve athletic performance, showing more potential than alkaline water.
Final Recap
To summarize, alkaline water is safe for human consumption. However, the concern is about the health claims and potential. Since there is not enough evidence to support its therapeutic benefits or to highlight its side effects, it is best to consult a medical professional first. Moreover, if you are using artificial alkaline water, ensure that you are sourcing it from a reputable brand that is free from contamination and contains essential minerals.
