Potential Benefits of Alkaline Water for Acid Reflux

Recent laboratory research on alkaline water has shown that it has benefits for reflux sufferers. Alkaline ionized water and a sensible diet have been shown to stop acid reflux as effectively as PPI medications. Moreover, the study results are very promising because clinical research conducted in Japan showed that 88% of people with digestive upset found partial or full relief of their symptoms by drinking alkaline water.

Alkalinity: Why alkaline water can neutralize acid

Alkaline water from a water ionizer neutralized 177 mg/L more acid than tap water

The chemical property that measures alkaline ionized water’s ability to neutralize acid is called alkalinity (not pH!). Alkalinity is tested by adding acid to an alkali until the pH of the alkali becomes neutral. For example, we tested alkaline ionized water with a pH of 10 against tap water here in Carlsbad (the home of Life Ionizers). We used hydrochloric acid with a pH of 2, (similar to stomach acid) and this is what we found:

  • Carlsbad tap water (pH of 7.8) neutralized 107 mg/L of acid
  • Alkaline ionized water from a Life Ionizer (pH of 10) neutralized 284 mg/L of acid

This means that alkaline ionized water from a Life Ionizer was able to neutralize more than twice as much acid as Carlsbad city tap water! The acid-neutralizing ability of alkaline water is the reason it has potential to neutralize acid in the body.

Pepsin: The other half of the acid reflux story

Hydrochloric acid is only one half of the acid reflux story. The other half is pepsin, an enzyme that triggers the damage that acid reflux does. Pepsin is not available to the public, so we aren’t able to test it in the lab here at Life Ionizers. However, lab tests show that alkaline ionized water permanently neutralizes pepsin.

Can alkaline water help your acid reflux?

You should talk to your doctor to find out for sure.  But recent research published in The Lancet suggests that eating a Mediterranean diet and drinking alkaline ionized water are just as effective as PPI drugs for acid reflux. So your chances of improving your digestive health by drinking alkaline ionized water are quite good.

If you are a researcher interested in performing clinical trials of alkaline water for acid reflux, contact Life Ionizers at 877-959-7977 and ask for Leo McDevitt.

Life Ionizers is very interested in assessing the effects of alkaline ionized water on acid reflux. If you are clinically diagnosed as an acid reflux sufferer, we may be able to offer you a special deal on a Life Alkaline Water Ionizer in return for your co-operation in our ongoing study of alkaline water for acid reflux.
