Fluoride
For fluoride exposure and its health risks
Most of the experts we follow would steer you away from it.
Our sources steer away from supplemental fluoride due to concerns about mitochondrial and water health.
Who is behind it
Voices including a board-certified cardiologist, a GP with a Master of Public Health and an optometrist of twenty years.
How strong the research is
Well studied in published research, as well as in practice.
In their words
“You just want to avoid fluoride in the Water Source Florida is a dielectric Blocker in physics terms that Florida Limits The amount of energy that the water in your body can store”

Where they disagree
Both sides
Against
