A few weeks ago, we started the discussion about alkaline water, detailing how its popularity has consumers wondering in what way alkaline water compares to a glass straight from the tap. This special type of water is said to buffer acids in the blood like lactic acid produced during hard exercise, however, it can only do so effectively when the water is high in alkalinity. But what exactly does that mean?
Our own health expert Dr. Michael Donaldson, Ph.D. shared his research about how beneficial alkaline water can be, just so long as the alkalinity is in tact.
Alkaline vs. Alkalinity: What’s the Difference?
Simply put, alkaline water is less acidic than regular tap water. Alkaline water is produced by passing water through an electrolysis chamber and enriching part of the water with hydroxyl ions (OH-), making it higher in pH. A waste stream is also created that is acidic. Alkaline water may or may not have alkaline-rich compounds, such as calcium, silica, potassium, magnesium and bicarbonate in it, depending on the source water. Alkalinity is defined as the water’s capacity to resist changes in pH that would make the water more acidic. Dr. Donaldson explained that it’s critical for consumers to understand this difference if they want to get the most out of their water.
“It is important to distinguish between alkaline and alkalinity,” said Dr. Donaldson. “Alkaline refers to pH, but alkalinity refers to the ability of the water to resist change in pH when acid is added
