TL;DR
Adding slightly acidic electrolyzed water (SAEW) to drinking water was found to be safe for mice and even improved their antioxidant levels and digestive health.
Key Finding
Slightly acidic electrolyzed water at low concentrations did not harm mice and appeared to enhance their antioxidant defenses, glucose metabolism, and digestive enzyme activity.
Summary
Researchers gave mice drinking water treated with slightly acidic electrolyzed water (SAEW)—a disinfectant that might accidentally be ingested through food and water—at two different concentrations for 60 days. The mice drinking SAEW showed no negative effects on growth or blood health, but did show improvements in antioxidant enzymes (proteins that protect cells from damage), glucose metabolism (how the body uses sugar), and digestive enzyme activity. The small intestine also developed better in mice drinking SAEW.
Practical Takeaway
This is an animal study in mice, so results may not directly apply to humans. While the findings suggest SAEW may be safe at low concentrations and could potentially support digestive and metabolic function, human studies would be needed to determine if these benefits translate to people. The study does not address hydrogen water specifically, but rather a disinfectant treatment applied to water.
Abstract (excerpt)
Slightly acidic electrolyzed water (SAEW) as a disinfectant might be ingested by humans and animals along with food and drinking water. The present study explored whether adding SAEW to drinking water affects the drinking water intake, food intake, body weight, intestinal morphology, digestive…
