Alkaline water has gained attention as a possible alternative to regular water. Celebrities like Gwyneth Paltrow, Mark Wahlberg, and Jennifer Aniston have endorsed alkaline water. But is there real proof of its benefits? Experts say the science remains uncertain.

Bottled alkaline water often contains added minerals such as calcium and magnesium to achieve an alkaline pH. A neutral pH is 7; above 7 is alkaline, below 7 is acidic.

Standard tap water has a lower pH compared to alkaline water. This has led some to suggest that alkaline water may neutralize body acidity. Claims also include potential prevention of health conditions like cancer and stroke, based on Mayo Clinic insights. Some studies indicate that added calcium in alkaline water might slow bone loss.

Research highlights potential benefits of alkaline water with a plant-based Mediterranean diet to relieve acid reflux. Several studies imply that alkaline water alone could alleviate gastroesophageal reflux disease (GERD) symptoms.

Mayo Clinic and other experts stress the need for more research to confirm these benefits over time.

Harvard Medical School’s Dr. Howard E. LeWine agrees about possible, though temporary, benefits. He comments that as stomach fluid is quite acidic, any alkaline water effect would not last long. Drinking significant amounts might temporarily raise stomach fluid pH, but the kidneys quickly restore the balance. Alkaline water may ease heartburn from acid reflux, but effects are short-lived. Antacids are considered more effective for relief.

Dr. LeWine noted potential risks for those on PPIs or stomach acid blockers. Mayo Clinic warns that alkaline water with pH over 9.8 can cause safety concerns, like hyperkalemia, due to high potassium levels.

Dr. LeWine shared similar concerns about increased blood pH affecting potassium levels, especially in kidney patients.

Holistic nutritionist Robin DeCicco shared with Fox News Digital that there’s insufficient evidence for long-term health benefits from alkaline water. She emphasized focusing on healthy dietary habits to lower body acidity. She advises eating real foods, reducing sugar, caffeine, and processed foods to help manage acidity. Eating vegetables, fruits, good fats, lean protein, and fiber can also support this goal.

For those experiencing acid reflux, DeCicco recommends consulting a doctor and maintaining consistent eating habits while avoiding lying down after meals and highly acidic foods.
