Why have we been hearing so much about alkaline water systems lately?  If you’re interested in improving your health and athletic performance, you are sure to find interest in the benefits of alkaline water and foods.

More clinical studies are needed to verify benefits of alkaline water, but anecdotal evidence suggests that higher pH water is good for you.

Click an item in the table below to skip ahead to your most pressing question or item, or continue on to read more.

Why does pH matter? 

Before we discuss water alkalizers, let’s take a trip down memory lane and discuss the pH scale.  pH, or “potential hydrogen,” runs a scale of  0 to 14.  Pure water is neutral and generally has a pH close to 7.  Numbers lower than 7 are considered acids, with numbers on the low end being strong acids.  Numbers higher than 7 are basic, or alkaline.  

You want to avoid touching or eating anything on the extreme ends of the pH scale.  Battery acid is on the far end of the acid side, at just about 0 pH.  Household lye is on the extreme end of the alkaline side, at about 13.5 pH.

Some studies have suggested that slightly alkaline foods may be healthy for us by buffering acid in our bodies.  

Foods with naturally alkaline minerals, such as calcium, magnesium, silica, bicarbonate, and potassium may improve gut health by neutralizing acid in blood and increasing oxygen.  It may improve athletic performance by buffering hydrogen ions created from exercise.

Alkaline water has been found to soothe acid reflux, as higher pH destroys pepsin, an enzyme that contributes to the condition.  Evidence also suggests that alkaline water and foods may kill off microorganisms.  Several studies indicate that alkaline ionized water may prevent diabetes.  

Given the benefits stated above, how do we acquire alkaline water?  Well, we can collect natural spring water that flows through alkaline minerals.  Or we can mimic mother nature’s processes and make our own with a water alkalizer.

How does a water alkalizer work?

There are several ways to make water alkaline.  One such way is to to pass water through a filter with minerals to increase the pH.

Another way is to use a machine called an ionizer.  In this process, water is first pre-filtered for contaminants.  Then, the water passes through a chamber containing mineral compounds, such as calcium carbonate and magnesium sulfate.  The chamber contains metal plates which produce an electric current, an electrolysis chamber.  

In the electrolysis chamber, a charge breaks apart the chemical bonds of the mineral compounds, allowing molecules to split and create two separate liquid streams.  Alkaline mineral water (containing the calcium or magnesium) is the end product, while an acidic stream of carbonic acid is typically the waste product.  Alkaline water produced through the process of ionization is for drinking, while the low pH stream is useful for cleaning your home.

Oxidation Reduction Potential, or ORP, is potential energy that causes beneficial microclustering, oxygenating, and antioxidant properties in alkaline water. Alkaline water tends to have higher negative values (e.g -170mV) for ORP, while acidic water has higher positive values (e.g +200mV).

If you’d like give alkaline water a shot, we’ve done our homework to find the latest in water alkalizers.  Below you can find Clean Water Today’s reviews of top alkaline water filters:
