Calcium and iodine counteract the effects of fluoride

From this article:
How to Reduce Fluoride Exposure and Toxicity

"Unlike natural calcium fluoride, synthetic fluorides lack calcium and act as calcium chelators, which means they bind strongly to calcium in certain tissues. “This binding disrupts various biological processes and contributes to toxicity,” Sauerheber said.
Sauerheber emphasizes that calcium plays a crucial role in minimizing fluoride assimilation and acts as an antidote to accidental acute fluoride poisoning by counterbalancing or neutralizing its toxic effects after ingestion."

"In addition to calcium, the toxicity of fluoride also depends on our iodine levels. Those with iodine deficiencies will experience more toxic effects from fluoride."

Milk is a rich source of both.

Thank you. I wonder if fluoride renders calcium unusable by the body?

The association of fluoride in drinking water with serum calcium, vitamin D and parathyroid hormone in pregnant women and newborn infants - European Journal of Clinical Nutrition

Chronic exposure to fluoride in drinking water causes an increase in plasma fluoride levels that is related to a reduction in calcium transport across the renal tubule endoplasmic reticulum and plasma membrane. In the present study, it was hypothesised that varying levels of fluoride present in...

Water Fluoridation: A Critical Review of the Physiological Effects of Ingested Fluoride as a Public Health Intervention

Fluorine is the world's 13th most abundant element and constitutes 0.08% of the Earth crust. It has the highest electronegativity of all elements. Fluoride is widely distributed in the environment, occurring in the air, soils, rocks, and water. Although ...

Fluoride exposure has a complex relationship in relation to dental caries and may increase dental caries risk in malnourished children due to calcium depletion and enamel hypoplasia, while offering modest caries prevention in otherwise well-nourished children.

Yes, in the 1st study, higher fluoride levels were associated with less calcium it seems.
It doesn't say why though.
I browsed quickly through the 2nd paper, and from both It seems to me that higher fluoride levels require higher calcium intake.

I think fluoride increases the need for nutrients especially magnesium. If magnesium is deficient/or being depleted then calcium cannot be used properly. At the same time calcium is binding the fluoride. This is probably why it is linked to hypertension.

Among its other effects, ingestion of fluoride increases the requirement for certain nutrients. For example, the metabolic requirement for magnesium is increased by fluoride, sequestering it into the skeleton and thereby making magnesium less available to other tissues. Ophaug and Singer reported that fluoride exerted a significant effect in retarding the mobilization of skeletal magnesium in rats.13 It has also been reported that fluoride has a biological interaction with magnesium and that excessive fluoride intake causes magnesium deficiency by decreasing its absorption from the intestine by forming magnesium fluoride.14 In addition, previous studies have shown that subjects with chronic fluorosis had lower serum magnesium levels. 15,16 Magnesium deficiency has been implicated in the pathogenesis of HT, with epidemiological and experimental studies demonstrating an inverse correlation between blood pressure and serum magnesium levels.17 Magnesium affects blood pressure by modulating vascular tone and reactivity. It acts as a calcium channel antagonist, it stimulates production of vasodilator prostacyclins and NO, and it alters vascular responses to vasoactive agonists.

Fluoride, Blood Pressure and Hypertension

Individuals with blood pressure readings that exceed 140/90 are considered hypertensive. Hypertension can increase the risk of stroke, heart attack, heart failure, aortic aneurysms, and peripheral arterial disease. An association between increased fluoride in ground water and increased...

Relationship of fluoride in drinking water with blood pressure and essential hypertension prevalence: a systematic review and meta-analysis - International Archives of Occupational and Environmental Health

Background and objective Previous studies showed controversial results of the relationship between fluoride exposure through drinking water and elevated blood pressure. We conducted a systematic review and meta-analysis to assess the direct relationship of drinking water fluoride exposure with...
