Water absorption

Andrew Huberman explains that drinking water with a higher pH, which is more alkaline than typical tap water, can increase the rate at which water is absorbed in the gut. This enhanced absorption is facilitated by the fact that more alkaline water moves more readily across the aquaporin channels in the gut. While Dr. Huberman does not insist on consuming high pH water for proper hydration, he acknowledges its benefits, including faster absorption and potentially reduced inflammatory responses 1.

Aquaporin channels play a crucial role in the absorption and movement of water through the cells of the body. These channels are found in various tissues, including the unique connective tissue called fascia, and are responsive to both the temperature and pH of the water. When transitioning from low to high mobility states, these channels facilitate increased water access to specific cells, which is critical for proper hydration and muscle function 2.
