According to product labeling and confirmation from bottling sources, Kirkland Signature purified drinking water does not have fluoride added to it. This is an important distinction for consumers, as Kirkland also offers a spring water product that does contain naturally occurring fluoride. The clarification is vital for those specifically seeking fluoride-free hydration options.

Over 200 million people in the U.S. receive fluoridated tap water, but for those who prefer spring water, a common question is if it naturally contains fluoride. Yes, spring water can and often does contain naturally occurring fluoride, though the amount depends heavily on the specific geological formations it passes through. This natural presence is not to be confused with the controlled addition of fluoride to municipal water supplies for dental health.
