Hydrogen Water Side Effects and Safety

What the research reports

• Hydrogen-infused water has been recognized as safe (GRAS) for use in drinking water in the United States
• Randomized trials have generally reported no significant side effects
• Hydrogen that isn't used leaves the body through the breath, usually within about an hour

Possible minor effects

• Some people notice mild bloating or loose stools when they start drinking more water of any kind
• Magnesium tablets add magnesium, which in large amounts can have a laxative effect
• Very alkaline water from ionizers (high pH settings) is not meant for drinking in large amounts — stick to drinking-water settings

Check with your doctor if you

• Have kidney disease or are on a fluid restriction
• Take prescription medications, especially for blood sugar or blood pressure
• Are pregnant or breastfeeding
• Are thinking of using hydrogen water instead of a treatment — don't

Product safety

• Choose portable bottles with a membrane that keeps byproducts like ozone and chlorine out of the water
• Use food-grade tablets as directed
• Don't try homemade chemical methods
