Alkaline water has a higher pH (typically 8-9) than regular water. Proponents claim it neutralizes acid in the body to prevent disease and slow aging. However, human blood pH is tightly regulated by robust homeostatic mechanisms (primarily renal and respiratory), making it virtually impossible to alter significantly through diet. The primary benefit, if any, is likely derived from adequate hydration rather than pH level.
Verdict
No evidence for healthspan benefits; focus on standard hydration instead.

Protocol
- Consume 1-2 liters daily in place of regular drinking water.
Flags
- The body's natural buffering systems tightly regulate blood pH, making dietary influence negligible.
- May reduce stomach acidity, potentially impairing protein digestion and nutrient absorption.
- Quality of home ionizers can vary significantly, posing a risk of contamination.
