A Scientific Look At The Relationship Between Fluoridated Water And Intelligence

2. 04) iq points per 1 mg/l up to 2. A significant inverse relationship was found between the fluoride concentration in drinking water and iq (r value = 0. 204; P < 0. 000). It was observed that iq level was negatively correlated with fluoride concentration in drinking water. P < 0. 000).

A 2018 study on the relationship between water fluoride and iq in children showed that excessive water fluoride exposure was associated with lower iq levels in subgroups. We have found a significant inverse relationship between intelligence and the water fluoride level, and intelligence and the urinary fluoride level. After adjusting for confounders, urinary fluoride. High levels of fluoride in drinking water may have a negative impact on intelligence, which could be a major health issue. A robust and continuous link between fluoride exposure and low.
