A new official government report has found that fluoride can in fact affect the IQ of children. People who have warned about this have been labeled as ”crazy” and ridiculed. But it turns out that the ”conspiracy theorists” were right once again. Researchers have now found that people drinking water containing more than 1.5 mg of fluoride per liter of water is linked to lowering IQ by as much as 5 points in children – this is really, really bad!
But guess what? The WHO has set the safe limit of fluoride in drinking water at 1.5 mg. Do you still trust the WHO?
Research has also found that pregnant women should avoid getting too much fluoride as it can reach the fetus. We now know that fluoride is neurotoxic.

Although not specifically named, the above study conducted in the USA and others like it worldwide caused the US Government’s National Toxicology Program to release a report this week linking higher levels of fluoride with neurobehavioral issues and lowered IQ. The conclusions from this report are as follows:

…higher levels of fluoride exposure, such as drinking water containing more than 1.5 milligrams of fluoride per liter, are associated with lower IQ in children. The NTP review was designed to evaluate total fluoride exposure from all sources and was not designed to evaluate the health effects of fluoridated drinking water alone. It is important to note, however, that there were insufficient data to determine if the low fluoride level of 0.7 mg/L currently recommended for U.S. community water supplies has a negative effect on children’s IQ.
The NTP uses 4 confidence levels – high, moderate, low, or very low – to characterize the strength of scientific evidence that associates a particular health outcome with an exposure. After evaluating studies published through October 2023, the NTP Monograph concluded there is moderate confidence in the scientific evidence that showed an association between higher levels of fluoride and lower IQ in children.
The determination about lower IQs in children was based primarily on epidemiology studies in non-U.S. countries such as Canada, China, India, Iran, Pakistan, and Mexico where some pregnant women, infants, and children received total fluoride exposure amounts higher than 1.5 mg fluoride/L of drinking water.
The U.S. Public Health Service currently recommends 0.7 mg/L, and the World Health Organization has set a safe limit for fluoride in drinking water of 1.5 mg/L. The NTP found no evidence that fluoride exposure had adverse effects on adult cognition.
It seems rather coincidental that the National Toxicology Program set the toxicology limit to just above 1.5 mg/L, which is the WHO recommendation for fluoride supplemented water.
“This review finds, with moderate confidence, that higher estimated fluoride exposures (e.g., as in approximations of exposure such as drinking water fluoride concentrations that exceed the World Health Organization Guidelines for Drinking-water Quality of 1.5 mg/L of fluoride) are consistently associated with lower IQ in children. More studies are needed to fully understand the potential for lower fluoride exposure to affect children’s IQ.”

The World Health Organization (WHO) set a safe limit for fluoride in drinking water at 1.5 milligrams per liter. Still, the US government report found that drinking water containing more than 1.5 milligrams of fluoride per liter is associated with lower IQs in children.
Humans vary enormously in the amount of water they drink per day. Studies show that warm climates, seasonal variations in temperature – particularly in warmer climates, age, BMI, and pregnancy all affect the amount of water a person consumes.
Of note, women in later pregnancy drink much more water per body weight. Infants consume a much larger volume of water per body weight. Herein lies the problem. As fluoridation in the water system is based on a weight/water volume (mg/liter) ratio, the more a person drinks, the more fluoride one consumes. Obese pregnant women living in warmer climates, without access to air conditioning, are likely to consume a much higher amount of water daily. By adding fluoride to the water, the amount consumed by any one individual will vary widely.
Furthermore, fluoride, which is put into toothpaste and other products, is routinely given to pregnant women, babies, and young children. The frequency of tooth brushing, fluoride ratio, and fluoride composition found in toothpaste formulas vary greatly.
Fluoride supplements are also often prescribed to pregnant mothers. Young children are often subjected to fluoride varnishing treatments and/or the use of fluoridated mouthwashes, gels, and toothpaste, particularly when fluoridated water is not available.
In rural settings, where people have well-water, women are often encouraged to take fluoride supplements, particularly in previous decades. For instance, when my wife, Jill, was pregnant with our first child in 1984, she was prescribed a fluoride supplement with the warning from her OB/gyn that tooth buds are formed in the neonate and that fluoride supplementation is necessary to prevent tooth decay.
The point is that 1) fluoride from drinking water can vary widely between individuals (warmer weather, pregnancy, individual drinking habits, weight, etc.), and 2) there are also other sources of fluoride, which can significantly increase a pregnant mother’s fluoride intake.
So, the WHO’s recommendation of 1.5 mg/L. is extremely high, given that women get fluoride from many different sources, not just water, and babies drink a lot of volume compared to body weight – particularly in warmer climates.
Worldwide health policies, conducted on millions, if not billions of people, can lead to vast numbers of people being adversely affected if those policies are later proven detrimental to health and wellness. In this case, millions of children will suffer from neurobehavioral challenges, making adult relationships difficult and cognitive issues.
Did the WHO purposefully ignore the warning signals that over-fluoridation of pregnant mothers and children could lead to decreased IQ and neuro-behavioral issues? Given that these peer studies began to be published at least five years ago, they must have known these guidelines were wrong (1), (2), (3), (4).
So, why does the WHO still recommend supplementation with 1.5 milligrams of fluoride per liter?
We have posted several articles on the subject of fluoride since February 2015 which began with the principle that people should not have something they don’t want to ingest forced on them, and grew increasingly against it as more adverse evidence got presented. We recommend this webpage on the Fluoride-Free NZ website which contains video documentaries, particularly the first on the upper left which was made by Reality Check Radio in January this year. —Eds
