Alkaline water has a higher pH level than regular drinking water. Because of this, some advocates of alkaline water believe it can neutralize the acid in your body. Normal drinking water generally has a neutral pH of 7. Alkaline water typically has a pH of 8 or 9. Alkaline water must also contain alkaline minerals and negative oxidation reduction potential ORP.
ORP is the ability of water to act as a pro- or antioxidant. The more negative the ORP value, the more antioxidizing it is. Alkaline water is somewhat controversial. Differences in research findings may be related to the types of alkaline water studies.
According to the Mayo Clinic , regular water is best for most people. They state that 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 study found that drinking naturally carbonated artesian-well alkaline water with a pH of 8. Another study suggested that drinking alkaline ionized water may have benefits for people with high blood pressure , diabetes , and high cholesterol.
A more recent study that included 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 efficiently blood flows through the vessels.
Those who consumed high-pH water reduced viscosity by 6. 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.
In particular, research is needed to answer other claims made by alkaline water supporters. Despite the lack of proven scientific research, proponents of alkaline water still believe in its proposed health benefits. These include:. They also argue that soft drinks, which are notoriously acidic, have very positive ORPs leading to many health problems, while properly ionized and alkalinized waters have highly negative ORPs. Green tea is rich in antioxidants and has a slightly negative ORP.
Some examples of negative side effects include the lowering of natural stomach acidity, which helps kill bacteria and expel other undesirable pathogens from entering your bloodstream. Additionally, an overall excess of alkalinity in the body may cause gastrointestinal issues and skin irritations.
Alkalosis can also cause a decrease in free calcium in the body, which can affect bone health. A review of the effects of alkalis on cancer was published by Dr. The review assessed thousands of studies, but the authors found only one proper, randomized test of acid in the diet and cancer of the urinary bladder. One study has suggested that an alkaline diet, but not specifically alkaline water, may enhance the action of some chemotherapy drugs used to treat cancer.
Acid reflux disease is when the contents of the stomach, which are acidic, splash back up the food pipe. Acid reflux that keeps happening for a long time can cause damage and a disease known as gastroesophageal reflux disease, or GERD. It found that alkaline water at pH 8. It also appeared to reduce the acidity of the stomach contents. The work was done in a laboratory rather than in humans. More research would be needed to support these findings. Moreover, stomach acid exists for a purpose.
It kills bacteria and other pathogens, and it helps our bodies to digest food and absorb nutrients. Scientists in Shanghai found that 3 to 6 months after drinking alkaline water, people with high blood pressure , high blood sugar, and high blood lipids had lower measures in each of these factors.
In , researchers found that a high-pH electrolyte water reduced blood viscosity in adults, after exercising. This may help reduce cardiovascular strain due to dehydration.
However, the scientists point out that participants had different measures of whole blood viscosity at the outset, which could have affected the results. It is worth noting that the study was sponsored by Essentia Water, who also provided the alkaline water used. As there is no evidence to support the health benefits of alkaline water, there is no recommended amount that improves health.
However, if you wish to start drinking alkaline water, start with a low intake and increase it gradually. This can reduce the corrosive effects of highly alkaline water.
A review published in the Journal of Environmental and Public Health concluded that an alkaline diet may have some benefits. Fruits and vegetables, say the researchers, have a negative acid load that could improve the balance between sodium and potassium , with possible benefits for bone and muscle health.
This could help prevent high blood pressure, strokes , and other chronic diseases. Children with severe metabolic acidosis tend to have low levels of growth hormone, and this can lead to short stature. An alkaline diet may help to reduce problems related to low growth hormone in those who are susceptible. An alkaline diet also appears to increase magnesium in cells. Magnesium, in turn, helps activate vitamin D. A study published in looked at the effect of consuming alkaline water on mice over a period of 3 years.
Results suggested that those who drank alkaline water had signs of greater longevity, in other words, they aged less and were more likely to live longer. No significant differences were seen in the heart, liver, kidneys, brain, or intestine of the groups studied, and no damage occurred, but there were differences in how the mice and their organs aged.
While it will not add calories as part of a balanced or managed diet, there is no research that supports alkaline water as a standalone weight loss remedy. Researchers who looked into the link between alkaline water, an alkaline diet, and cancer said that an alkaline diet could be harmful, as it encourages people to avoid foods that contain important nutrients. Here are some typical results for refrigerated ionized water, stored in a sealed glass container:.

Yes, alkaline ionized water is best stored in an airtight glass or stainless steel container. The alkaline properties will be retained for weeks, but they are strongest when fresh within the first 3 days. The antioxidant properties start to diminish after hours.
