Is drinking ionized alkaline water proven to be beneficial to a person's health?

It is pseudoscience placebo crap. Just like all those mobile phone stickers that increase reception and prevent radiation, or all those magnets that magnetize water or remove limescale from the pipes. Note how commercials for this nonsense call distilled water "dead".

http://en.wikipedia.org/wiki/Water_ionizerA water ionizer is an appliance that ionizes water. Ionized water is claimed by manufacturers to be extremely beneficial to human health and marketed with claims that it is an antioxidant which can slow aging and prevent disease. 1 Others note that such claims contradict basic laws of chemistry and physiology.

2 edit IonizationMain article: Electrolysis of waterA water ionizer separates water into alkaline and acid fractions using a process known as electrolysis. 3 It does this by exploiting the electric charge of the calcium and magnesium ions present in nearly all sources of drinking water. When a source of water lacks mineral ions, such as distilled water, or has been filtered by reverse osmosis, water ionization has no effect.

Edit UsesSome research suggests that alkaline reduced water may be useful in scavenging free radicals in the laboratory setting. 4 Tests on in vitro lymphocytes suggest that reduced water can prevent hydrogen peroxide-induced damage to DNA, RNA and certain proteins. 5 However, drinking ionized water would not be expected to alter the body's pH, and there is no evidence of any claims made by manufacturers that drinking ionized water will have a noticeable effect on the body.

2Electrolyzed water has been used by the food industry to sanitize food products; though effective in bacterial solutions, it was found less useful when sanitizing utensils, surfaces and food products. 6 Acidic electrolyzed water (pH 2.3–2.6) may have use as a seed surface disinfectant or contact bactericide. 7http://www.antiaginglifeextension.com/water-ionizers/default.aspWATER IONIZERS - Drink High pH Ionized Water For Total Health Yes, it's true...You Can Rejuvenate Your Bodyby Drinking High pH Ionized Waterand Markedly Improve Your Health!

Alkalized, High pH, Ionized WaterHelps Reverse Aging,Alkalizes and Detoxifies andSaves You Money at the Same Time...All With Just the Push of a Button! Now Boosting Your Immune System toFight Free Radical and Oxidative Damage to Your Cells While Neutralizing Acidity in Your Bodyis as Easy as Drinking a Glass of Water! There are many water filtration systems and high-priced bottled waters to choose from today, all of which have their own problems, including... * Reverse osmosis, which makes water acidic and depletes the water of all its minerals; * Filtration systems, which only remove solids; * Distilled water, which is dead; * Tap water is not very pure and the pH is too low; and * Today’s well water, which is contaminated because our aquifers are contaminated from decades of dumping waste in our rivers, streams, and ground.

None of the above choices provide your body with what it really needs to help you live a long and healthy life, naturally until the creation of the "Rejuvenator" system which simply and effectively turns ordinary tap water into superior, ionized, alkaline water - the right kind of water! You cannot get good alkaline water from bottled waters and certainly not from ionized water. Bottled water is either filtered tap water or bottled spring water.

All of these normal sources do not have a pH high enough to alkalize your body and they all have positive instead of negative Oxidation Reduction Potential (ORP) values. Positive ORP is exactly the opposite of the very healthy negative ORP value of good ionized water. Negative ORP protects your cells against destructive oxidation, whereas positive ORP does not.

Buying bottled water is a waste of money because bottled water is not good ionized water. Instead, put a filter in line with your tap water. You’ll save money and get the same results as bottled water, however, you still won’t get the good ionized alkaline water your body needs.

Only good, ionized alkaline water has the pH level, purity, and negative ORP value that will alkalize your body and prevent the dangerous acidic and destructive oxidation of your cells which is the cause of most degenerative diseases and obesity.
