Fluoride
Fluoride is the ionic form of the element fluorine, found in drinking water, tea and seafood. The body builds it into tooth enamel and bone.
Does it strengthen bones enough to prevent fractures?
Fluoride can stimulate bone formation, which prompted osteoporosis research. Trials have produced conflicting fracture findings. In a one-year trial of 180 postmenopausal women, 2.5, 5 or 10 mg daily did not improve bone mineral density. These experimental doses are not supplement recommendations. 1
