What about the hype about alkaline water

What is basic water? Is it really useful or just hype?

For several years, alkaline water has been enjoying increasing popularity, especially with health-conscious people and professional athleteswho either follow an alkaline diet or want to improve their hydration. Even well-known NBA stars like Carmelo Anthony and LeBron James swear by alkaline water. According to reports, some professional basketball players have several cases of alkaline water delivered to their homes every month.

The pH value plays a major role in our general health. Many people mainly eat foods that contain refined sugar, hydrogenated fats, too much salt, glucose-fructose syrup (corn syrup with a high fructose content), chemical additives, pesticides and synthetic hormones and highly industrially processed were. Such a diet can lead to a Acidosis lead, so an acidification of the blood, a trailblazer for many different diseases.

Some claim that alkaline water - or water with a high pH value - is the best water for our health. Then leave this statement with a list of the many advantages for our health follow from weight loss to increased resistance to cancer. But does the water live up to its reputation or is it just a new trick to pull the money out of the pockets of health-conscious consumers? Let's take a closer look at the topic.


What is basic water?

Alkaline water has one higher pH than normal water as well as a negative redox potential. Natural, alkaline spring water is best. The pH value is a measure of the acidity of a liquid. A low pH indicates that the substance more acidic is a higher pHthat they more basic (or more alkaline). Too many hydrogen ions mean that the cells have less oxygen available, which leads to a higher acid content as the pH falls. Fewer hydrogen ions mean that more oxygen is available, which makes the solution more basic (more alkaline). So far there is no known disease that can survive in an alkaline environment.

With its higher pH, basic ionized water is said to be more beneficial than normal tap water. Alkaline water usually has a pH around 8 or 9, the pH of water is 7.0 or slightly below. It is also claimed that alkaline water is more important minerals that the body absolutely needs to keep it functioning properly, such as calcium, potassium, sodium and magnesium.

The pH in our body:

On average, your blood should have a pH of 7.365 (on a scale of 0-14). That would one Base-acid ratio of 60:40 correspond.

Alkaline compounds buffer acids in the blood with four main alkaline minerals - calcium, magnesium, sodium and potassium - which work together to maintain the body and all bodily functions.

  • Calcium strengthens our bones and contributes to healthy blood circulation.
  • magnesium is involved in the conversion of food into energy and contributes to the maintenance of muscles, nerves, the heart and kidney function.
  • sodium controls blood pressure, ensures a balanced fluid balance and influences muscle movements.
  • potassium supports the relaxation and contraction of muscles. This is particularly important for the heart muscles. The mineral also contributes to healthy digestion and the breakdown of fluids.

Our body always tries to maintain a slightly alkaline pH value in the blood. This requires that he sometimes has to tap into certain body reserves - heavy work for our body.

The basic water debate

Unfortunately, so far only a lot few research results about the potential benefits of alkaline water. In addition, many manufacturers make completely exaggerated claims that are completely unfounded just to sell expensive products like basic water filtration systems instead of providing consumers with science-based health information.

Proponents of basic water argue that there are a number of differences compared to acidic water health benefits offer. Alkaline water is said to stimulate the metabolism, slow down bone breakdown, reverse aging processes and improve the absorption of nutrients by neutralizing existing acid in the blood, which can lead to diseases. They feel that tests cannot always diagnose mild acidosis and that your body experiences the hidden effects.

Critics agree that alkaline water can offer health benefits. It is unclear, however, whether this resulted from the higher pH values ​​or the higher mineral content. Hence a warning to everyone: Be suspicious of health claimsthat sound too good to be true. Also keep in mind that not all basic water and systems for ionizing water are available high-quality are. Opt for trustworthy productswho keep their promises.

However, it is not that easy to increase the pH value in the body or in the individual organs. Time and again, critics point out that drinking alkaline water may not be the answer to your low pH, especially if the root cause is unknown. In addition, our bodies are not designed to be permanently in an alkaline state.

Think about the base to acid ratio of 60:40 that we mentioned earlier. Continuous consumption of alkaline water can upset your body's delicate pH levels and adversely affect your health.

Alkaline water - structured water - normal water - mineral water

There are many in every supermarket these days different types of water available. In the past, the selection was limited to normal drinking water, today it ranges from alkaline water to structured water and mineral water.

Ordinary drinking water from the supermarket usually contains this purified water, which is made up of tap water that is filtered and so from through a process called reverse osmosis Cleaned impurities and microorganisms has been. This water only contains traces of minerals, including calcium, magnesium, potassium and sodium. Purified water generally has an acidic or neutral pH of 7.0 or below.

In contrast, mineral water comes from, and typically contains, a mineral spring Variety of minerals such as salts and sulfur compounds. Mineral water is available both still and sparkling, depending on whether it contains added carbon dioxide gases or not. Like basic water, it can also contribute to that Supply of minerals to our body do what can have a positive effect on our health.

Structured water is a type of water that has not been filtered or processed. This water is basically like this as it occurs in nature. Some people believe that there is one higher amount of energy contained and “optimally charged”, which helps our cells to function more efficiently. Similar to alkaline water, it should have an optimal pH value and have a positive effect on energy intake, digestion, mood and other aspects of our health. But even in this case there are only very few research results, so that there are no reliable findings as to whether or how structured water can influence our health.

5 advantages of alkaline water

  • improves blood circulation
  • relieves acid reflux symptoms
  • improves the moisture balance
  • regulates blood sugar
  • promotes bone health

1. Improves blood circulation

Some research suggests that basic water is the Blood circulation improvedso that the blood can flow more easily around the body to carry oxygen and important nutrients into the tissues. Researchers suspect that the water reduces the viscosity or thickness of the blood so that it can move through the bloodstream more efficiently.

In any case, these are the results of a Study from 2016published in the Journal of the International Society of Sports Nutrition. As part of the study, 100 healthy adults drank either normal or alkaline water to compensate for their fluid loss after a strenuous training session. Interestingly, the subjects who received alkaline water decreased blood thickness by 6.3 percent. In the control group, the researchers recorded a drop in viscosity of just 3.36 percent.

2. Relieves symptoms of acid reflux

Acid reflux, also known as GERD, is a condition in which stomach acid flows back into the esophagus, causing symptoms such as belching, gas, and nausea. Pepsin is an enzyme that is responsible for breaking down proteins. It plays one Key role in acid reflux and can trigger the symptoms.

Alkaline water can have a positive effect on neutralizing pepsin and thus reducing symptoms. An in vitro study by the Voice Institute of New York showed that alkaline drinking water with a pH of 8.8 could help deactivate pepsin. From the study results one can therapeutic benefit for people who suffer from acid reflux.

However, in this context, you need to be aware that blocking pepsin only temporarily masks the underlying problem, much like antacids (stomach acid drugs). So alkaline water can help that Relieve symptoms of acid reflux, but does not fight its cause.

3. Improves the moisture balance

It is crucial for our general state of health and our well-being that we supply our body with sufficient fluids at all times. Sufficient water regulates body temperature, helps with Transport of nutrients and at the Elimination of waste products.

Researchers suspect that alkaline water has a better effect on the moisture balance than conventional drinking water. A study published in the Journal of the International Society of Sports Medicine found that consuming alkaline water over a period of two weeks not only increased the pH of blood and urine, but also increased the body's hydration levels as opposed to normal Water improved.

4. Regulates blood sugar

A consistently high blood sugar level can have a negative impact on your health and lead to increased thirst, headaches and fatigue more serious, long-term consequences how visual disturbances and nerve damage lead.

In this case too, research results are only available to a very limited extent. However, some preliminary studies show that basic water can help Balance blood sugar levels and maintain normal blood sugar levels. This has a beneficial effect on your health. A six-month study from China showed that alkaline water significantly lowered the subjects' blood sugar levels to normal values. Scientists from the Department of Obesity Management at Dongduk Women's University at the Graduate School of Obesity Science carried out an animal experiment and published their results in the journal "Life Sciences". They report that basic water antidiabetic effects and can reduce blood sugar levels and glucose tolerance in mice.

5. Promotes bone health

A diet high in acidity promotes the breakdown of bone mass as more calcium is excreted in the urine. An alkaline diet, on the other hand, can prevent bone resorption and thus contribute to bone health.

Some studies suggest that alkaline water can help keep bones strong by affecting certain hormones that cause the Bone metabolism Taxes. For example, a study by the Center of Bone Diseases at Lausanne University Hospital in Switzerland with 30 women showed that consuming alkaline water lowers the levels of parathyroid hormones, which cause bones to release calcium into the blood. In addition, consuming the water lowered a biomarker that shows changes in bone turnover.

Recommendations regarding basic water

Although some promising studies have found positive health effects of alkaline water, most of them are small studies with significant limitations. In this respect, it is not possible to make general statements regarding the health benefits of alkaline water.

As with almost all things in life, the dose matters. Eating a healthy, nutritious diet with lots of whole foods and fresh fruits and vegetables is still the best way to balance your body's pH and stay healthy.Ultimately, alkaline water cannot replace the multitude of vital nutrients that our body needs from food.

In addition, consuming too much alkaline water as well as alkaline foods over a long period of time can lead to one Alkalosis lead and unbalance the body. This can lead to serious health problems and inhibit the production of pepsin. This affects the stomach's ability to break down food and protein.

Just eat more fresh fruits and vegetables like apples, lemons, limes, leafy greens, and carrots. In this way you keep your pH value in balance and at the same time make an important contribution to your health.

If you also want to consume alkaline water in moderation, this is absolutely fine. But before you start looking for the best alkaline water or buy an expensive alkaline water ionizer, try to prepare your own alkaline water with simple means. There are many instructions on how to do this on the Internet. Usually you add baking soda (base powder) or lemon to your water.

However, remember to only consume alkaline water as part of a balanced diet and a healthy and active lifestyle. This is how you get the full benefit from it for your health.


Too much alkaline water upsets the pH balance in the body and can cause serious health problems, such as alkalosis. This can lead to side effects such as nausea, vomiting, tremors, and confusion.

Regular consumption of alkaline water can reduce the activity of pepsin in the stomach. As a result, proteins can no longer be broken down effectively. It also disrupts the natural acidity of the stomach acid, which is necessary to kill harmful bacteria and pathogens and prevent disease.

If you choose to drink alkaline water, please do so only in moderation and as part of a healthy, balanced diet and regular exercise. How to keep your body healthy.
