1. Improves Circulation
Some research suggests that alkaline water may improve circulation, allowing blood to flow more easily through your body to deliver oxygen and important nutrients to your tissues. It’s believed to work by reducing the viscosity, or the thickness of the blood, helping it move through the bloodstream more efficiently.
This was demonstrated in a 2016 study published in the Journal of the International Society of Sports Nutrition that gave 100 healthy adults either regular water or alkaline water to rehydrate after a strenuous workout. Interestingly, those who drank alkaline water experienced a 6.3 percent decrease in blood thickness compared to just a 3.36 percent drop in viscosity in those who drank regular water. (4)
2. Reduces Acid Reflux Symptoms
Acid reflux, also known as GERD, is a condition in which acid moves back up through the esophagus, causing acid reflux symptoms like belching, bloating and nausea. Pepsin, the enzyme responsible for breaking down proteins, plays a key role in acid reflux and can trigger symptoms.
Alkaline water may have a beneficial effect on neutralizing pepsin to reduce symptoms. One in vitro study out of the Voice Institute of New York demonstrated that drinking alkaline water with a pH of 8.8 helped deactivate pepsin, potentially providing therapeutic benefits for those suffering from acid reflux. (5)
However, it’s important to keep in mind that blocking pepsin acts as a temporary bandage to the real underlying problem, similar to the effect of antacids. While alkaline water may help provide relief from symptoms, it may not actually treat the root of the acid reflux itself.
3. Increases Hydration
Staying well-hydrated is crucial to overall health and wellness. Getting enough water regulates your body temperature, helps transport nutrients and aids in waste removal.
Alkaline water is believed to enhance hydration even more than standard drinking water. A study published in the Journal of the International Society of Sports Medicine showed that drinking alkaline water for two weeks not only increased alkalinity in the blood and urine, but also improved hydration status to a greater degree than those drinking regular water.

4. Regulates Blood Sugar
Sustaining high levels of blood sugar can take a big toll on your health, with side effects ranging from increased thirst, headaches and fatigue to more serious, long-term consequences like impaired vision and nerve damage.
Although research is limited, some preliminary research has found that alkaline water may help balance blood sugar to maintain normal blood sugar levels and promote better health. One six-month study in China showed that drinking alkaline water significantly reduced blood sugar levels to normal range in participants. (7) An animal model conducted at Dongduk Women’s University’s Department of Obesity Management at the Graduate School of Obesity Science and published in Life Sciences also found that alkaline water had anti-diabetic effects, reporting that it reduced blood sugar and improved glucose tolerance in mice.

5. Improves Promote Bone Health
A highly acidic diet has been shown to increase bone loss by upping the excretion of calcium through the urine. An alkaline diet, on the other hand, can prevent bone resorption to help preserve bone health. (9)
Some studies suggest that alkaline water may help keep bones strong by influencing certain hormones that affect bone metabolism. One study out of the Centre of Bone Diseases at Lausanne University Hospital in Switzerland composed of 30 women, for instance, showed that drinking alkaline water decreased levels of parathyroid hormone, which causes bones to release calcium into the blood. Not only that, but it also lowered levels of a biomarker used to measure the rate of bone turnover as well.
