Gastroesophageal reflux, also known as GERD (Gastroesophageal Reflux Disease), is an increasingly common condition, affecting millions of people around the world. Among the most frequent symptoms are heartburn, chest pain, chronic cough, hoarseness and a sore throat. These symptoms most often result from the corrosive action of gastric acid and the enzyme pepsin on the oesophageal mucosa – let’s find out about the relationship between drinking alkaline water and gastro-oesophageal reflux.

Did you know that alkaline water can be an effective and natural ally in combating this discomfort?

The Scientific Study: Alkaline Water pH 8.8 and Pepsin Inactivation

In 2012, a pioneering study conducted by Johnston and Koufman and published in the journal Annals of Otology, Rhinology & Laryngology analysed the impact of alkaline water with a pH of 8.8 on the enzyme pepsin, one of the main culprits responsible for damage to the oesophagus in cases of reflux.

The study’s main findings:

  • Buffering action: alkaline water neutralised gastric hydrochloric acid, reducing total acidity.

  • Irreversible inactivation of pepsin: This finding is extremely important because pepsin, even in less acidic environments, can remain active and aggressive. Alkaline water has been shown to permanently inactivate it.

  • Therapeutic potential: The study concluded that regular intake of alkaline water with a pH of 8.8 can be an effective complement to conventional treatment for GERD, acting in a safe and natural way to reduce gastro-oesophageal reflux.

Why choose alkaline water?

Alkaline water, with a pH higher than 7, is increasingly valued not only for neutralising excess gastric acidity, but also for supporting the body’s pH balance and improving general well-being.

For reflux sufferers, the benefits can include:

  • Reduced heartburn and inflammation

  • Less need for continuous medication

  • Protection of the oesophageal mucosa

  • Improved digestive quality of life

Testimonials and Growing Evidence

In addition to the 2012 study, several users of water ionisation systems report significant improvements in reflux symptoms.

Although it doesn’t replace medical supervision, alkaline water is increasingly considered a safe complementary alternative for those who wish to avoid the side effects of drugs such as proton pump inhibitors.

Final thoughts

Gastroesophageal reflux is a serious condition, but with natural and affordable alternatives like alkaline water, it’s possible to control symptoms and improve gastrointestinal health.

Johnston and Koufman’s study reinforces the value of alkaline water as a non-pharmacological adjuvant, above all because of its ability to neutralise gastric acid and inactivate pepsin – one of the oesophagus’ biggest aggressors.

If you suffer from reflux or want to prevent wear and tear on your digestive system, it’s worth considering incorporating alkaline water into your daily routine.
