What is the Effect of Mineral Water on Your Kidneys?

Do you enjoy your mineral water plain or with a slice of lemon on a warm day? This refreshing drink has sparked some debate about whether its acidity affects the kidneys.

When you're enjoying the sun and a glass of water seems boring, you might go for some mineral water with some lemon. It's a great alternative to sugary drinks, but there's a common question: Is mineral water bad for your kidneys?

In the grocery store, you'll generally find two types of carbonated water: Carbonated water, which is plain water with added carbon dioxide and sometimes additional minerals or salt for flavor, and mineral water, which is naturally carbonated from a mineral spring.

Dietitian Lauren Sullivan from Cleveland Clinic explains that whether carbonated water is healthy depends on its added ingredients: "Carbonated water can contain sugar, artificial sweeteners, caffeine, and other additives. The best choice is plain carbonated water."

Harvard T.H. Chan School of Public Health suggests drinking plain carbonated water with a squeeze of lemon if you find plain water unappealing. This is a healthier alternative to sugary drinks.

Lauren Sullivan notes that there are few studies showing negative effects of mineral water on kidneys. Concerns often arise because carbonated water is slightly acidic, but Healthline clarifies: "Drinking acidic drinks like carbonated water doesn't make your body more acidic. Your kidneys and lungs remove excess carbon dioxide."

Choosing sugar-free and additive-free mineral water can offer some health benefits. Importantly, proper hydration is crucial for kidney health, and a lack of it can lead to kidney problems, including kidney stones. Cleveland Clinic also highlights that carbonated water can help you avoid sugary sodas, which can harm your kidneys if consumed in excess. Staying hydrated helps your body flush out toxins and prevents kidney stones and related issues like bladder infections. 

While generally safe and healthy, mineral water can have some potential side effects. People with sensitive stomachs might experience burping, bloating, or gas; the Cleveland Clinic suggests reducing intake if these symptoms occur. Additionally, versions containing citric acid, phosphorus, or sugar can erode tooth enamel. 

Nutritionist Wendy Bazilian advises that plain water is the best for kidney health. Harvard details that water helps with digestion, replenishes fluids lost through metabolism, and prevents overheating. It also lubricates joints and tissues, making it the perfect calorie-free drink to rehydrate your body.
