Kangen water made by a Kangen machine is artificially made alkaline water, natural alkaline water would be for example spring water with a pH of 7 or there about, a Kangen machine produces ionised water and itís ionisation that is the process used to create alkaline water.
Another name for ionised water is ERW Electrically Reduced Water, it simply means that electrolysis has been used to ionise the water, electrolysis is the process of passing an electric current through the water so that it becomes ionised, the ions in the water which are positively or negatively charged have their charge altered by the ionisation process and become more or less alkaline depending on the level of electric charge used, alkaline water and artificially created alkaline water is perfectly safe to drink.
Water ionisers are designed for the home, to electrically alter the pH of drinking water, the electrolysis process separates the tap water into its acidic and alkaline components, alkaline water it is claimed can alter the bodies level of acidity but this statement is subject to a lot of controversy with no medical proof that is what happens when you drink alkaline water.
More accurately ionised water can be alkaline or acidic, the salts and minerals present in the tap water will also be present in the ionised water, the ionisation process does not add or remove and salts or minerals, additional filters can be added to the tap water hose to remove heavy metals, chlorine or fluoride, but these are filters and not specifically part of the water ioniser.
Itís claimed that drinking ionised water means that your drinking acid fighting water that will provide your body with antioxidant benefits ridding your body of acidic diseases, again there is no proof that alkaline water can rid your body of disease or make you look younger, there are plenty of personal testimonies from users saying that ionised water has cured them of everything from gout to heart disease but there is no medical proof to this.
Itís also claimed, wrongly that ionised water creates micro-clusters in the water which allow the ionised water to pass through skin pores, tissue and cell membranes more easily than regular tap water, this is not true the hydration abilities of ionised water and tap water are the same, you may be drinking more ionised water than tap water and therefore be getting your hydration from ionised water but the ability for the body to absorb ionised water is the same as for tap water.
Alkaline ionised water proponents also claim that the benefits of drinking the water also include lowering high blood pressure and reducing or eliminating diabetes, there is no medical proof that ionised water has these benefits.
Water ionisers like the Kangen not only produce ionised alkaline and acidic waters but also filter the water that your drinking, the filter might be a simple mechanical filter or sieve, a charcoal filter removing bacteria from the water or a activated alum filter filtering out fluoride from the water.
Whilst Kangen water is a trademark of Enagic, the type of water that the Kangen machine produces is called alkaline ionised water and there are many alternative water ionisers that can produce this alkaline water and not just the Kangen so if you want an alkaline water machine typically one third the price of a Kangen then you can buy another brand of water ioniser.
Fans of Kangen water have been quoted as saying the alkaline ionised water from a Kangen is different from the alkaline ionised water from a third party alkaline ioniser and they would be right, the third party machine is cheaper!
