Episode notes
Researcher Discloses Industry Collaboration
- Andy Galpin discloses his lab is running a study with Echo Water, which makes a hydrogen-generating flask.
- He says he prepared deeply for that study and knows the research on hydrogen water well.
Hydrogen Water ≠ Alkaline Water
- Hydrogen water is not the same as alkaline water and the naming is confusing.
- Andy emphasises that molecular/hydrogen water is a different concept from pH-altered alkaline water.
Body pH Is Regulated Locally
- Alkaline water changes pH but stomach acidity neutralizes it, so it won't alter body pH.
- Andy notes body compartments have distinct, necessary pH ranges and forcing alkalinity can be harmful.
