How Do Alkaline Water Systems Affect Your Stomach pH AND Gastrointestinal Health?

When it comes to alkaline Mineral water and its impact on stomach acidity, there are often questions and misconceptions. You might wonder how alkaline water, which is known for its high pH, interacts with your stomach's acidic environment.

Municipal tap water is typically recommended to have a pH of 7 by the Environmental Protection Agency. Alkaline water typically boasts a pH of 8 to 9.

Hydrochloric Acid's Role in Your Stomach

To comprehend the interaction between alkaline water and your stomach, it's essential to understand the role of hydrochloric acid (HCL) in your gastric system. Your stomach produces HCL, a strong acid, to aid in food digestion and kill harmful bacteria. Your stomach pH is typically maintained at around 4, creating an acidic environment conducive to these functions.

The pH Adjustment Process

When you consume alkaline mineral water or alkaline-rich foods, your stomach pH rises. This prompts your body to respond by producing more hydrochloric acid to lower the pH back to its optimal level of around 4.

At first glance, it may seem like you're increasing acid production, which could be worrying. However, there's more to this process than meets the eye.

Note: It's essential that your stomach doesn't store hydrochloric acid reserves waiting to be released. Instead, HCL is secreted as needed to maintain the acidic environment required for digestion. If the stomach had a constant reserve of HCL, severe health issues would result.

Hydrochloric acid production involves a chemical reaction that combines water (HO), carbon dioxide (CO), and sodium chloride (NaCl). This reaction yields hydrochloric acid (HCl) and sodium bicarbonate (NaHCO) as byproducts. Here's the simplified equation.

NaCl (sodium chloride) + HO (water) + CO (carbon dioxide) = HCl (hydrochloric acid) + NaHCO (sodium bicarbonate)

This sodium bicarbonate enters your bloodstream, where it serves a vital role—it neutralizes solid acidic waste and converts it into a liquid form that can be easily expelled from your body. This mechanism ultimately alkalizes your body.

Alkaline Mineral Water's Overall Effect

Alkaline Mineral Water's Overall Effect

When you examine the complete picture of how alkaline water interacts with your body, it becomes evident that alkalinity gains overall. While it may seem that the stomach's function of producing hydrochloric acid is counterproductive to alkalinity, the introduction of sodium bicarbonate into your bloodstream counteracts this effect.

  • The stomach produces hydrochloric acid to facilitate food digestion and bacteria elimination.
  • When you consume alkaline mineral water, the stomach also produces alkaline byproducts (such as sodium bicarbonate) that enter your bloodstream to neutralize acidic waste.
  • Consuming alkaline mineral water will not deplete your stomach of alkalinity; there is a net gain.

Acid Reflux and Mineral Ionized Water

One area where alkaline Ionized water has shown promise is relieving acid reflux symptoms.

  • A study conducted over two decades ago revealed that alkaline water with a pH of 8.8 could permanently neutralize stomach acid (pepsin), relieving acid reflux.
  • A subsequent trial in 2017 compared alkaline water and a Mediterranean diet to proton pump inhibitors (PPIs), commonly prescribed for acid reflux. Surprisingly, the results indicated that the combination of diet and alkaline water was as effective as PPIs, with the diet showing the most significant benefit.
  • The study authors also suggest that a plant-based diet and alkaline water might serve as a superior alternative for acid reflux treatment.

Alkaline Mineral Ionized Water and Irritable Bowel Syndrome (IBS)

One notable study conducted in 2018 focused on individuals with irritable bowel syndrome (IBS) characterized by diarrhea.

Participants who consumed a minimum of two liters of alkaline-reduced water (ARW) daily for eight weeks experienced significant improvements in their symptoms and overall quality of life. This randomized double-blind, placebo-controlled pilot study suggests ARW relieve IBS-D.

Benefits for Gastrointestinal Diseases

A review of studies conducted in 2021 sheds light on emerging evidence regarding alkaline-reduced water (ARW) and its potential therapeutic properties. ARW, which is typically produced through electrolysis involving the passage of electric current through water, possesses specific characteristics, including an alkaline pH, high hydrogen content, and an extremely negative Oxidation Reduction Potential (ORP).

This review suggests that ARW have antioxidant and anti-inflammatory properties that benefit various gastrointestinal diseases, including Gastritis (Stomach Inflammation) and indigestion.

For bottled water to qualify as alkaline, it must contain alkalinizing minerals such as calcium and magnesium carbonate. Additionally, it should possess negative oxidant reduction potential, acting as an antioxidant, like blueberries or fish oil. The solution to this problem is an Alkaline Water Ionizer Machine.
