Alkaline water purports to neutralize acid in the body, which proponents claim can prevent diseases and slow aging. However, the body tightly regulates blood pH through robust homeostatic mechanisms, rendering dietary pH impact negligible. Scientific evidence supporting healthspan benefits is largely absent.
Verdict
Hydrates, but healthspan benefits are not scientifically supported.

Protocol
- Regular intake of water with a pH typically above 8.0, often through bottled alkaline water or ionization devices.
Flags
- No robust evidence supports claims of systemic pH alteration or healthspan benefits.
- Excessive consumption of highly alkaline water may theoretically disrupt stomach acid.
- Can be significantly more expensive than regular tap water without proven benefit.
