Fluoride is added to water and can be harmful, not enough to see it immediately, so it is still added to our water. It can lead to lower IQ, ADHD / ADHD / ADD and possibly many other diseases: https://www.youtube.com/watch?v=-hvhAEiB19M Meanwhile it is in the water, food, toothpaste and although many claim little does no harm, it adds up and the greater the amounts, the worse the effect. In addition, the body can't break down the toxins so well, it thinks fluoride is calcium and integrates it into bones. Basically, it is a poison that is artificially added to our water. I would like to see a natural mineral water that clearly states that it is fluorine-free, but unfortunately I can't find one.
