Alkaline water is somewhat controversial. Many health professionals argue against its use, saying there isn’t enough research to support the many health claims made by users and sellers. According to the Mayo Clinic, regular water is best for most people, as there is no scientific evidence that fully verifies the claims made by supporters of alkaline water.However, there are a few studies that suggest alkaline water might be helpful for certain conditions.For example, a 2012 study found that drinking alkaline water with a pH of 8.8 may help deactivate pepsin, which is the main enzyme that causes acid reflux.Another study suggested that drinking alkaline water may have benefits for people who have high blood pressure, diabetes, and high cholesterol.A more recent study that included 100 people found a significant difference in whole blood viscosity after consuming high pH water compared to regular water after a strenuous workout. Viscosity is the direct measurement of how blood flows through the vessels. Those who consumed high pH water reduced viscosity by 6.3 percent compared to 3.36 percent with standard purified drinking water. This means blood flowed more efficiently with alkaline water. This can increase oxygen delivery throughout out the body.However, more research is needed beyond these small studies, specifically into some of the other claims made by alkaline water supporters.Despite the lack of proven scientific research, proponents of drinking alkaline water still believe in its many proposed health benefits, which include:
- anti-aging properties (via liquid antioxidants that absorb more quickly into the human body)
- colon-cleansing properties
- immune system support
- hydration, skin health, and other detoxifying properties
- weight loss
- cancer resistance
