Referring to a common salt of fluoride, sodium fluoride (NaF), the lethal dose for most adult humans is estimated at 5 to 10 g (which is equivalent to 32 to 64 mg elemental fluoride/kg body weight). [ 2 ] [ 3 ] [ 4 ] Ingestion of fluoride can produce gastrointestinal discomfort at doses at least 15 to 20 times lower (0.2–0.3 mg/kg or 10 to 15 ...
Antifluoridationist literature links fluoride exposure to a wide variety of effects, including AIDS, allergy, Alzheimer's disease, arthritis, cancer, and low IQ, along with diseases of the gastrointestinal tract, kidney, pineal gland, and thyroid, though there is no scientific evidence linking fluoridation to these adverse health effects.

The pineal gland (also known as the pineal body [1] or epiphysis cerebri) is a small endocrine gland in the brain of most vertebrates. It produces melatonin , a serotonin -derived hormone , which modulates sleep patterns following the diurnal cycles . [ 2 ]
Most patients with skeletal fluorosis show side effects from the high fluoride dose such as ruptures of the stomach lining and nausea. [3] Fluoride can also damage the parathyroid glands, leading to hyperparathyroidism, the uncontrolled secretion of parathyroid hormones. These hormones regulate calcium concentration in the body.
The fluoride ion is readily absorbed by the stomach and intestines. Ingested fluoride forms hydrofluoric acid in the stomach. In this form, fluoride crosses cell membranes and then binds with calcium and interferes with various enzymes. Fluoride is excreted through urine. Fluoride exposure limits are based on urine testing, which is used to ...
Also, although fluoride affects the physiology of dental bacteria, [90] its effect on bacterial growth does not seem to be relevant to cavity prevention. [91] Fluoride's effects depend on the total daily intake of fluoride from all sources. [13] About 70–90% of ingested fluoride is absorbed into the blood, where it distributes throughout the ...
Kids whose mothers had higher levels of fluoride in their urine were 83% more likely to exhibit a range of neurobehavioral issues, including anxiety, emotional reactivity and physical complaints ...
The research had two goals: (1) to warn communities with a high concentration of fluoride of the danger, initiating a reduction of the fluoride levels in order to reduce incidence rates of fluorosis, and (2) to encourage communities with a low concentration of fluoride in drinking water to add fluoride in order to help prevent tooth decay.
