To be precise, alkaline water or water that has been “alkalized” refers to water with a higher pH than tap water. The pH scale, which measures how acidic or basic something is, runs from zero to 14, with seven being the neutral point. Anything below seven is considered acidic, while anything above seven in basic. Most tap water has a pH of 7.
Alkaline water typically has a pH greater than that of tap water. Water is alkalized through an agent – calcium or magnesium for instance – bringing its pH up to 8 or 8.5, according to Self Magazine. Bottled water brands like Essentia and Evamor are considered alkaline waters.
Health benefits of drinking alkaline water
The benefits of drinking alkaline water vary depending on who you ask. According to the Mayo Clinic, some studies suggest regularly drinking alkaline water can help slow bone loss. Other studies suggest alkaline water can help ease acid reflux woes due to its higher pH levels. The most straighforward benefit of alkaline water, however, is its super hydrating quality, which brands like Essentia and Evamor promote on their websites.
Possible dangers of alkaline water
Although some doctors and experts sing the praises of alkaline waters, others are wary. Registered dietitian Alyse Levine argues in Shape Magazine that the studies of alkaline water are largely inconclusive or incomplete. Levine notes that clinical studies simply don’t exist to support many of the claims made.
Moreover, depending on your current health, drinking alkaline water could prove to have negative effects on your body. For people with kidney disease, higher levels of alkalinity could prove disastrous, according to the Nephron Information Center.
