5 Good Reasons You Should Avoid Fluoridated Water

Fluoride was originally added to water supplies back around the time of the end of World War II, but this well-intended practice to improve dental health is still around today, and more and more people are recognizing the possible dangers. Certainly, a lot of people out there will tell you there’s no problem with fluoridated water, but these people are simply repeating outdated studies that are not backed by current evidence.

Why You Need to Avoid Fluoridated Water

Drinking fluoridated water may seem like a good idea, but it’s actually anything but. Not only can consuming fluoride harm the brain, it also has severe impacts on hormonal health. Here are 5 reasons to avoid it like the Plague.

1. Fluoridated Water Can Damage the Thyroid

A recent study reported water fluoridation in England is linked to a 30 percent increase in the rate of under active thyroid; still, other reports suggest 2 to 5 mg of fluoride over months can actually reduce thyroid function. [1] [2] Close to 70 percent of the U.S. water supply is fluoridated. But should we really be putting an endocrine disruptor like fluoride into the water we drink?

2. Fluoridated Water is Linked to ADHD

With a more than 50 percent increase in the past 10 years, ADHD is becoming a big problem in the U.S. [3] So what’s causing this increase? Well, if you live in a state with fluoridated water, that could even be a factor. For the first time, scientists have “found that states with a higher portion of artificially fluoridated water had a higher prevalence of ADHD,” and it seems like more than just a fluke: the trend even “held up across six different years examined.” [4]

3. Fluoridated Water Lowers IQ

New data suggests fluoridated water could even lead to brain damage and lower IQs in kids. [5] As a neurotoxin, fluoride could even cause damage equivalent to that from a traumatic brain injury. Some experts believe that adding fluoride to the water supply is not only reckless, it’s immoral. Unfortunately, many of the individuals in control of fluoridating water are unaware of the hazards of the toxin. [6]

4. Fluoridated Water Can Cause Fluorosis

Too much fluoride can affect teeth and bones. The World Health Organization (WHO) says ”fluoride levels above 1.5 mg per litre cause pitting of tooth enamel and deposits in bones. Levels above 10 mg per litre cause the crippling skeletal fluorosis.” [7] In the U.S., we’re often exposed to levels in the 2 to 5 mg range, but in India, fluorosis is such a concern that, in 2008, the government had to create a national health plan to combat excess fluoride in the water. With the way the U.S. loves its fluoride, why couldn’t that happen here?

5. Fluoridated Water Damages the Pineal Gland

Fluoride damage to bones and teeth isn’t the only issue; the toxin can also build up in very high levels in the pineal gland. [8] Located in the brain, this gland is responsible for melatonin synthesis and production. While it’s not known just how fluoride can damage the gland, one thing melatonin controls is the start of puberty in girls, and some evidence suggests the build-up could be a factor in early onset.

Avoid Fluoride at All Costs

Fluoridated water is causing all sorts of damage to our bodies—maybe even more than we know. Sure, there’s an old argument that taking the fluoride out of the water supply would significantly damage oral health; but, in the 21st century, is that still the best argument?

What do you think? Do the potential risks outweigh the benefits of fluoridation? Tell us what you think in the comments.

    Here’s one good reason to drink optimally fluoridated water:

    It prevents dental decay, with no adverse effects.

    There is not one, single valid study in that list of “references”, which demonstrates any of the adverse effects attempted by this author to attribute to optimally fluoridated water. I will be glad to explain to Dr. Group if he would care to be properly educated on fluoridation.

    It is very difficult to find a filter that filters our fluoride, and chlorine too.
    Any suggestions? Thank you!

    I don’t want to take a bath or shower in fluoridated water. I have sensitive skin.
    I don’t want to wash my hair with fluoride — it will make it brittle.
    I don’t want to make my coffee or tea with fluoride.
    I don’t want to have my grandchildren ingest this chemical. If they need fluoride for their teeth, they can get it from their dentist. Why pour it into their little bodies?
    My mother-in-law has a transplanted kidney and must stay away from fluoride.
    I don’t want to be forced to buy unfluoridated bottled water.
    Hitler used fluoride on his people.
    KEEP OUR WATER FRESH, CLEAN AND PURE! The people who want or need this chemical can buy it for themselves. The people who don’t want it shouldn’t be subjected to it.

    1. You have been taking baths and showers, washing your hair, and making coffee or tea with fluoride as long as you have engaged in those activities, fluoridated water or not. Fluoride has existed in water since the beginning of time. This fluoride is identical to that which is added with fluoridation. Don’t bother to claim that it is not. It is. A fluoride ion is a fluoride ion, regardless the source compound.

    2. Your mother-in-law must carefully monitor her intake of all substances in strict accordance with instructions from her doctors. This is not limited to fluoride. That severely medically compromised individuals, such as your mother-in-law, must strictly monitor their intake, is not a reason to deprive entire populations the benefit of a very valuable public health initiative such as fluoridation.

    3. Hitler did not “use fluoride on his people”.

    4. No one is forced to do anything in regard to water fluoridation. Optimally fluoridated water is colorless, odorless, tasteless, and causes no adverse effects. For those who have an irrational phobia of fluoride in their water, there are certainly alternatives, such as non-fluoridated bottled water. However, that is their choice. No one will force them to do anything.

    5. Your water contains a number of routine additives, such as chlorine and ammonia, in addition to fluoride. Removal of fluoride would not render your water any more FRESH, CLEAN, AND PURE!” than it is with the fluoride.

    People who are gullible enough to believe they need to add fluoride to their water can go fluoridate themselves.

    Get a bottle of sodium fluoride drops from the pharmacist. Add 7 drops to one cup of water.

    Or get a box of sodium fluoride powder from an exterminator. Add a tiny pinch to a gallon of water.

    Worst choice: dump fluoride obtained from a fertilizer factory into the entire water supply, as the fluoride salesmen hope we will do.

    reverse osmosis filter or distallation system. note: not to be a debbie downer, but the reverse osmosis filters have a lot of plastic. plastic tubing and the bladder of the water tank is polyethylene.

    You need to educate yourself on Fluoridation. Look up the Alcoa Company in 1940 Sodium Fluoride which is in our water. It is TOXIC Waste. You have NO Idea!. By the way there are Studies on how Fluoride causes CANCER! Look it up.

  • Steve Slott


    Your definition of “educate yourself on Fluoridation” is obviously the lazy perusal of antifluoridationist websites. Thank you, but I will remain with legitimate sources of accurate information on this public health initiative.

    What is in your water are fluoride ions identical to those which have always existed in water. A fluoride ion is a fluoride ion, regardless of whether the source compound is NaF, CaF, HFA, or any other compound. This is just elementary chemistry.

    If you have valid, peer-reviewed scientific evidence that optimal level fluoride causes “CANCER!”, then produce it, properly cited. As none exists, I will not hold my breath in anticipation.

    ……or you could just simply understand that there is no rational reason to filter optimal level fluoride out of your water.

    I don’t see any need to fluoridate our water supply. Sell fluoride pills to your patients, but I don’t want my family to have the extra exposure to neurotoxins. Teach kids to brush & floss. My son is an athlete and drinks gallons of water!
    No thanks!!!!

    You are certainly welcome to your personal opinion.

    Reason #6 why you should avoid fluoridated water:

    Because village idiots like Steve Slott say it’s good for you to drink a little bit of insecticide with every glass of water.

  • Joe Roy

    People don’t realize how harmful fluoride can really be! The best approach is to simply avoid it altogether. For example, home water filters that use reverse osmosis can be quite effective at removing it.
