    Is Alkaline Water Good for Kidneys?

    It’s a controversial topic roaming on the internet: is alkaline water good for kidneys? There is no definitive answer. Some proponents claim its numerous benefits, while others claim its drawbacks. However, clinical research is required to support these findings.

    Let’s dive into insight and learn about alkaline water’s benefits and side effects.

    What is Alkaline Water?

    Water’s pH level will let you know its alkaline or acidic nature. Alkaline water has a higher pH than tap or regular water. The pH level will measure a solution’s acidity or alkalinity on a scale from 0-14. 

    Water with a pH of 7 is said to be neutral, while water with a pH below 7 is acidic. However, a liquid above a pH level of 7 is considered alkaline, ranging from 8 to 14.

    Moreover, the pH of tap water ranges from 6.5 to 8.5, while alkaline water has a higher pH level than regular water. Many brands contain a pH of approximately 9 due to the presence of minerals such as calcium, magnesium, potassium, and bicarbonate.

    The Process Of Making Alkaline Water

    Alkaline water naturally flows over rocks sourced from springs because it contains minerals. However, some manufacturers make water more alkaline by using a chemical process known as electrolysis- an electric device that splits water into acidic and alkaline solutions. Then, an alkaline solution will be preserved for bottling. 

    Moreover, they can add minerals, such as calcium, magnesium, potassium, and sodium, to make water more alkaline. The manufacturer also added some nutrients, such as baking soda, to increase the water’s pH level.

    Why is Alkaline Water Bad for the Kidneys?

    Alkaline water is not bad for the kidneys, but the minerals in alkaline water disturb the medication and affect those who have kidney issues or are taking kidney medication.

    Therefore, consuming excessive alkaline water increases kidney workload, ruining kidney function and causing further damage. It is recommended that you consult with your doctor before drinking alkaline water.

    Is Alkaline Water Good For Kidneys?

    Yes, alkaline water is good for the kidneys and possesses numerous health benefits to incorporate into your routine. However, there is a need for extensive clinical research on these findings.

    Let’s explore each benefit below.

    1. Maintain pH Levels in the Body

    Proponents or supporters claim that alkaline water might balance the body’s pH level by neutralizing acids present in the body. 

    Different brands of alkaline water have different pH levels. Therefore, you must check bottled water’s pH levels before buying any alkaline brand.

    2. Fulfill Your Hydrating Requirements

    Alkaline water is easily absorbed and more hydrating than tap water. A study on 36 male soccer players in ‘Biology of Sport’ stated that during arduous exercise, the amount of lactate or lactic acid produced in the body creates a burning sensation. 

    Therefore, drinking alkaline water maintains hydration and adequately utilizes the lactic acid or lactate. However, more scientific research is required to support these findings.

    3. Improves Bone Health

    Alkaline water contains natural minerals that support bone health. A study in Journal Bone determined the effects of acidic and alkaline mineral water on 30 female participants, dividing them into two groups.

    Consumers in the alkaline water group showed fewer markers of bone resorption (breaking down the bone and leading to bone loss) than those in the acidic water group.

    Furthermore, one more study illustrated that 100 postmenopausal women who drank alkaline water enhanced their bone density, suggesting it might help treat osteoporosis.

    4. Uplifting the Immune System

    Advocates of alkaline water claim that it will boost the immune system and fight against diseases.

    Furthermore, a Medical Gas Research journal study demonstrated that alkaline water positively affects gut health, gut microbiota, and stool consistency.

    5. Preventing Kidney Stones

    Dr. Marc Richards, M.D., a board-certified nephrologist in Florida, demonstrated that consumption of alkaline water could increase the pH of urine and make it more alkaline. 

    As a result, drinking alkaline water prevents certain kidney stones, mainly those caused by oxalates (a central component of kidney stones). Calcium sticks with oxalates and prevents kidney stones from occurring.

    6. Therapy for Chronic Kidney Disease (CKD): 

    A study finds alkaline water helps with chronic kidney disease. However, clinical research needs to be more extensive on this finding. 

    A small study finds that a person on alkali therapy improved their kidney function and glomerular filtration rate (GFR). Also, alkali therapy reduces the waste product known as creatinine serum, so your body works better than before. 

    These findings are only for some kidney patients and require more detailed research.

    Potential Risks and Side Effects of Alkaline Water

    Alkaline water is safe to drink in moderation. A proponent of alkaline water claims that there are some drawbacks to drinking alkaline water.

    1. Fluctuation in Blood pH Level:

    Excessive consumption of alkaline water leads to a slight imbalance in blood pH levels. This might cause problems for kidney disease patients. However, a pH level imbalance is improbable because the body maintains the blood pH level.

    2. Trigger Digestive Issues:

    Drinking an excessive amount of alkaline water may lead to digestive issues such as nausea, vomiting, and stomach pain. However, evidence is sparse for this finding.

    3. Disturbance in Medications:

    Excessive alkaline water will speed the absorption of acidic medications and quickly absorb them in the blood. On the other hand, it will slow down the alkaline medications.

    4. Erosion of Tooth Enamel

    When you consume alkaline water immoderately, you will likely erode tooth enamel over time. However, acidic beverages are better to consume.

    Can Alkaline Water Cause Kidney Stones?

    There is no direct answer available as the research is limited. Some studies suggest that alkaline water prevents kidney stones, while others say it will increase kidney stones. 

    The controversy is still going on. Therefore, it is best to consult your doctor or nephrologist before consuming alkaline water.

    Final Thoughts

    There’s a huge debate about whether alkaline water is good for kidneys. Some studies suggest that alkaline water helps in gastroesophageal reflux disease (GERD) and chronic kidney disease and enhances hydration. However, clinical research needs to be more extensive in supporting this.

    Excessive drinking of alkaline water leads to hyperkalemia, potassium imbalance, and faster absorption of acidic medications.

    In a nutshell, no conclusive evidence elaborates on the benefits and drawbacks of drinking alkaline water. It is better to consult your doctor before making any decision.
