Alkaline water: Better than plain water?
Medically reviewed on February 8, 2018
For most people, plain water is better.
Bottled water sold as alkaline water, which is subject to regulation by the Food and Drug Administration, might have nutrients added to it to achieve an alkaline pH. Because alkaline water has a higher pH level than does plain tap water, proponents say that it can neutralize acid in your bloodstream. Some say that alkaline water can help prevent disease, such as cancer and heart disease. However, more research is needed to verify these claims.
Some studies also suggest that alkaline water might help slow bone loss, but further investigation is needed to determine if this influences overall bone mineral density and if the benefit is maintained over the long term.
