While water fluoridation is purported to decrease your risk of dental cavities, fluoride needs to be applied topically for this to work. It doesn’t benefit your teeth when swallowed.
Swallowing fluoride displaces iodine from your thyroid, as iodine and fluoride are both halogens. Without iodine, you cannot make active thyroid hormones, raising your risk for Hypothyroidism.
Fluoride is a mitochondrial poison that sabotages your mitochondria’s ability to create cellular energy in the form of ATP, and an enzymatic reactor, meaning it reacts with enzymes in your body.
