What is an Alkaline Ionizer Machine?
These machines work when water flows over electrically charged plates that ionize (or electrolyze) the particles in the water. This makes the water richer in either hydroxyl ions (OH-), creating alkaline water, or hydrogen ions (H+) making acidic water.
The resulting negatively charged alkaline water is suitable for drinking, whereas the acidic water can be used for cleaning. The machine automatically diverts your chosen type of water to the outlet pipe. If you choose alkaline water, then the acidic water will drain into your sink.
These machines require calcium or magnesium (cations), and salts or bicarbonates (anions) to ionize the water. These occur naturally in water, but many companies add filters that contain them to ensure the ionization process is as effective as possible (5).
The plates that the water flows over are made of platinum, titanium, or a combination of both. These are hard, dense materials that help accelerate the natural ionization of water.
How to Choose an Alkaline Water Machine
Alkaline water machines all serve a similar purpose, but there are still some key differences from unit to unit. Before you start searching for a model, here are some key considerations that you should keep in mind:
Who Needs Alkaline Water?
According to a few studies, people with certain conditions (such as acid reflux or high blood viscosity) might benefit from drinking alkaline water.
A limited study in 2018 by researchers in Japan showed that drinking alkaline electrolyzed water was associated with a minor improvement in stool in 60 participants.
After a vigorous workout, the complete blood viscosity was shown to be significantly different after drinking high-pH water as opposed to conventional water, according to a study that was conducted in 2016 and comprised a total of one hundred participants.
Those who drank water with a high pH showed a reduction in viscosity, which was 6.3% more than those who drank water with a conventional purification level.
This indicates that the alkaline water promoted better circulation of the blood. This may increase the delivery of oxygen to all parts of the body.
Nevertheless, beyond these limited studies, there is a need for additional research. In particular, research is required to provide evidence for the other claims of alkaline water proponents.
Does Alkaline Water Affect Kidneys?
Drinking alkaline water is generally not recommended if you have kidney problems. It is safe to drink if your kidneys are currently healthy. If you suffer from kidney disease, consult with your physician before drinking alkaline water.
Are Alkaline Ionizer Water Machines Worth It?
The opinions on whether alkaline ionizer water machines are worth it are divided. People buy these machines because they like the idea of neutralizing body acids for a diet balanced in alkaline acids.
Alkaline water can temporarily neutralize stomach acids, but its science is more complicated than that. However, since alkaline water is unlikely to harm you if you are currently a healthy person, it is worth it to buy an alkaline ionizer machine.
The quality of the water produced by an alkaline ionizer highly depends on the water it is placed on. Des your water come from the tap, a well, or do you buy it in bottles?
To begin, you should make the most of the opportunity to educate yourself regarding the kind of water that you put into your alkaline ionizer. The EPA has recognized hundreds of contaminants that are present in your water supply.
Which Is Better, Ionized Water or Alkaline Water?
It’s difficult to determine whether ionized is better or worse than alkaline water because they are pretty different from one another. Drinking alkaline or ionized water may throw off your body’s natural pH balance and inhibit your stomach from properly digesting the food you eat.
In addition, if you drink an excessive amount of alkaline water, you may cause your stomach to overcompensate by producing more gastric acid.
Which Is Better, Tyent or Kangen Alkaline Ionizer Machine?
Because Tyent water ionizers have a power supply that is both larger and more efficient than that of Kangen machines, they are capable of producing more powerful electrolysis. As a result, Tyent makes alkaline water with a higher pH level than its competitor.
