Water alkaline is a particular type of water characterized by a pH above 7.0. Alkaline water Most bottled waters have an alkaline pH. Although there may be wide differences between them in terms of fixed residue and type of minerals contained. Here you will get a complete guide about what is alkaline water & also all about alkaline water. The alkaline water par excellence is ionized water purified and processed thanks to a device called an ionizer.
Production of Ionized Water
Ionization (always preceded by filtering) is a controlled electrolysis process. It is obtained by exposing the water to a low voltage current; the latter passes between two platinum-coated titanium electrodes (one positive and one negative pole), immersed in the liquid inside an insulated chamber. Ionization tends to separate cations from anions and produces two types of water at the end of processing.
Cations are positive ions that concentrate on the negative electrode and result in cathodic or reduced (alkaline) water. Anions are negative ions that concentrate on the positive electrode and produce oxidized or anodic (acidic) water. The two fluids come out separately from the machine and, while the ionized. The acidic water is more suitable for washing and cleansing (for hands, food, etc.).
What is alkaline water?
Alkaline water is a fundamental drink (almost a progenitor) of the acid-base diet. This should be obtained by increasing the body’s pH by choosing “basic” foods and drinks. Proponents of the What is alkaline water diet claim contemporary Western nutrition (North America).
The products responsible for lowering the physiological pH would also be guilty of increasing the incidence of certain diseases and uncomfortable conditions such as:
- Heart problems.
- Hormonal alterations.
- Loss of muscle mass.
- Loss of bone mass.
Water also contributes to the diet’s pH, and some types show a clear tendency towards acidity, particularly tap water. According to the acid-base diet affirms, tap water would be strongly acidifying. And tend to be pro-oxidant due to the polluting principles and “wrong” minerals that characterize it. It is no coincidence that the followers of this nutritional philosophy define. This type of drink is “dead water” and, by the same principle. Assert that alkaline water can help the body metabolize nutrients and expel toxins more effectively.
This would promote health by improving physiological performance. Thanks to the buffering effect on toxic acid products accumulated in the body (which would literally be “neutralized”). To support this hypothesis, there would also be a historical trace. Archaeological findings from Ethiopia’s Rift Valley indicate that hominids spent much of their evolution in this area (from Homo ergaster to Homo Sapiens). By carrying out various samplings of the surrounding waters. It emerged that all the surrounding lakes have a strongly alkaline water pH (up to 9.5-9.7), which would justify the human race’s survival and evolutionary progression.
Alkalizing Mechanism of Water:
From a chemical perspective, alkaline water owes its therapeutic capacity to the Oxidation Reduction Potential (ORP). This parameter describes a molecule, ion, or compound’s ability to release electrons (oxidizing – positive ORP) or to receive electrons (reducing, becoming an antioxidant – negative ORP).
For example, the body’s natural antioxidants (coenzyme Q10 ) or those introduced with food (vitamins A, C, and E) have a negative ORP. Ultimately, thanks to its predominantly alkalizing electrolytes such as calcium. The silicate of potassium, magnesium, and bicarbonate, alkaline water should exert a potent antioxidant function.

Why Can’t Food and Drinks Alter the pH of Blood?
The body’s acid-base balance is supported by a series of very effective physiological mechanisms. Under normal conditions, the blood’s pH does not undergo significant changes. And is maintained in conditions of slight alkalinity, between 7.35 and 7.45.
Small but clinically significant blood pH changes can be recorded in certain pathologies (usually of a renal nature or severe and decompensated diabetes ). During some drug therapies or extreme food behaviors (a ketogenic diet and similar). Fluctuations in blood pH greater than ± 0.4 points are accompanied by severe organic compromise and can be lethal in the absence of treatment.

For urine, it is different.
The same cannot be said about the pH balance in the urine. These represent an essential means of excretion for the body, and more precisely, they constitute the “waste of the blood.” The foods and drinks, acidic or basic, are not capable of altering blood pH because the control systems keep it balanced, neutralizing ( bicarbonate, albumin, and hemoglobin ) or expelling ( pulmonary ventilation and renal filtration) molecules potentially responsible dell ‘ alteration.
As we have seen, part of the unwanted (non-volatile) acid molecules and ions are filtered out by the kidneys and are concentrated in the urine. Some regulation systems molecules also end up in the excretory fluid; however, there is also a selective reabsorption process, which is why the urine can become much more acidic or basic than the blood.

Other Alleged Interactions between Diet and Blood pH
Ionized later proponents of the acid-base diet and alkaline water speculate. In practice, it would not be the blood’s pH to very dangerously. But the concentration of some minerals normally contained in the bones and muscles. These would be used as a buffer system to counteract food acidosis, causing the depletion of stocks in the long term.
Indeed, blood buffer systems are mainly made up of:
- Bicarbonate-carbonic acid.
- Monobasic-dibasic phosphate.
Followed and supported by:
- Renal control: for the excretion of fixed acidity (e.g., keto acids).
- Pulmonary control: for the excretion of volatile acidity (e.g., carbonic acid).
The only mineral mentioned among the blood buffer systems is phosphorus, which, not surprisingly, is among the salts most present in human nutrition.
It is true that renal control also involves potassium, sodium, calcium, etc. These elements’ significant expulsion increases their absorption capacity in the intestine (the mechanism is much more complex than it seems.
Any depletion in the body of minerals can only be caused by the simultaneous presence of
- Poor recruitment.
- Endocrine pathologies.
- Excessive excretion (probably also of a pathological nature).
All this explains why alkaline water cannot exert any relevant effect on the pH of the blood; at most, it can:
- Exert a beneficial effect on the formation of certain kidney stones (but simultaneously increases the risk for other kidney lithiasis types).
- Contribute to electrolyte balance in the long term (it is a possible source of potassium, magnesium, and calcium).
- Therefore, it would be advisable to focus more on the quantity. And type of minerals that characterize alkaline water rather than on the final pH.
- Furthermore, let’s not forget that some kidney diseases and the intake of certain drugs can easily induce the metabolic accumulation of minerals and lead to significant side effects.
Alkaline water and hydration
Unsuitable in case of kidney diseases and drug therapies. That affect filtration or require acidic urine. Alkaline water may instead be advisable for maintaining hydration. The intake of alkaline water participates in reducing urine production and the osmolality of the blood. Allowing to maintain higher levels of hydration and ensuring the fluidity of the blood in the cardiovascular system.
NB. Recall that a high osmolality of plasma is associated with an increased risk of death from stroke. These effects are not instantaneous but gradual, which suggests a hypothetical long-term benefit.
Alkaline water and Sport
Some suppose that alkaline water can promote sports performance. During motor physical activity, many hydrogen ions are produced (freed from lactic acid ), lowering the pH. Drinking alkaline water could improve buffering capacity, optimizing performance; the mechanism is the same as with sodium bicarbonate supplements. But it does not show the same negative effects, which are:
- Gastrointestinal reactions ( diarrhea ).
- Excess sodium in the diet (predisposing to hypertension in sodium-sensitive individuals and sometimes responsible for worsening gastritis ).
NB. By reinforcing the alkaline water with potassium and magnesium, greater tolerability to fatigue could be achieved, especially in long-lasting performance.
Alkaline Water and Disinfectants for Potabilization
Tap water is made drinkable by a series of chemical-physical processes. In the long term, an excess of residues left by the disinfectant molecules could favor. The accumulation in the body and cause negative effects on health. With the purification and ionization process. However, even in alkaline water, certain types of pollutants remain and in even higher concentrations. This means that alkaline water is not necessarily a better product than regular water.

Alkaline Water and Intestinal Flora
As anticipated, water alkalinization induces a change in the redox potential (English acronym ORP). This seems to change intestinal bacteria’s composition, but it is not clear whether.
Alkalinized water and AGE
Advanced glycosylation is a non-enzymatic process that occurs in people with chronic hyperglycemia ( diabetics ). This is a negative effect that leads to the formation of harmful products for different body tissues.
A study on rats affected by high AGEs has highlighted a possible protective role of alkaline water on the liver. However, it is not a question of real scientific evidence. But rather a basis on which to deepen with further experimentation.
Benefits of Alkaline Water
The difference between normal water and alkaline water lies in the Ph. Is the latter is higher than 7.0 as it is subject to ionization processes? And lightness on the palate but nothing more. It does not cure diseases, has no antiallergic potential or anything else.
If you adopt it in a healthy diet made up of fruits and vegetables, possibly controlled organically, little lean meat, little dairy, and zero alcohol. It helps you keep a healthy, fresh, and fit body. It is good, exactly like natural mineral water, and you can also buy it ready-made. But if you like having it at home, you can also try making it yourself.
Can Domestic water Alkalized?: What Is Alkaline Water
As a rule, the cities’ drinking water is controlled by the municipal aqueducts. But for those who absolutely want to create light and clean water with their own hands. The idea of making alkaline water at home could work. What does it take to get it? The recipes are different and almost all-natural.
For example, soaking a chopped organic lemon in pure water and salt (possibly Himalayan). And leaving it covered for 12 hours at room temperature. Filter everything and drink the water that you will obtain. Or: mix a teaspoon of baking soda with clean water, stir, let it rest for a while and then strain.
Or boil the water for 5 minutes, then put it in a clean or sterilized jug and cover. Once cold, you can drink it safely. Several companies sell “ionizers” to obtain alkaline water in a few minutes. Still, natural methods are more reliable and less expensive.
In addition to the recipes we mentioned above. And often invite you to mix them with home water to get the alkaline water you want. These are powders derived from corals, algae, and herbs, but it is always better to talk to a good herbalist to not make mistakes and create harm instead of benefits.
Some supplements can have side effects such as constipation, kidney stones, allergies. It is not the case to risk blindly for lighter water than normal in exchange. Always inquire, even with your doctor, about the production of alkaline water.
There are only a few anecdotal pieces of evidence to support the hypothesis. That alkaline water is a beneficial food for acid-base balance and healthy bones and/or skeleton maintenance. The only chemical or nutritional significance concerns the relationship between mineral salts, electrolyte balance, and certain renal lithiasis forms. It is conceivable that alkaline water can improve athletes’ overall hydration status in the long term. But this is only a hypothesis.
Thanks to the alkalization process, the water loses some of its pollutants. But on the other hand, it retains others in higher concentrations. The change in ORP affects the intestinal bacterial composition, but it is not clear how and to what extent. In some studies on rats, alkalized water has shown a hepatoprotective effect against AGEs.
The consumption of alkaline water may be advisable for all healthy subjects. Who do not follow drug therapies intended for urinary regulation? It is a valid alternative to normal water and could have some positive effects; the lack of scientific evidence does not necessarily correspond to this product’s total ineffectiveness. Among the various applications, probably the most important is in the sports field. However, I would recommend enriching the liquid with magnesium, potassium, and glucose to obtain an isotonic drink.
