It was a loud, clanging alarm bell for every community fluoridating water…

And every person putting fluoride into their bodies.

But the information was completely suppressed in America… until now.

For years, we’ve known that water fluoridation can be harmful to children’s brains – and can even lower their IQs.

Now, a new study out of China has reached a truly terrifying conclusion.

The damage to kids may start while they are still in the womb.

If you have children or grandchildren thinking of having babies, please don’t miss this.

Because the potential harm is serious… and it may be irreversible.

Pro-fluoride activists want to convince you that fluoridated water is a perfectly normal, accepted public health measure.

It is not.

As I’ve told you before, most of the world – including developed countries – does not fluoridate water.

These countries have access to the same research and data as us – and they are actively avoiding fluoride.

So what do they know that we’re ignoring?

Oh, plenty.

A massive meta-analysis of 74 studies – pretty much the gold standard of research – found “significant inverse associations between fluoride exposure and children’s IQ scores.”

In other words, the more fluoride they were exposed to, the more kids’ IQs dropped.

That was frightening enough. But it was just the start.

Because now it looks like fluoride might not wait until kids are born to start harming them.

In this new study out of China, researchers exposed pregnant mice to fluoride. And not crazy amounts, either – these were amounts you might encounter in everyday use, through your drinking water or toothpaste.

The fluoride caused lasting damage to the reproductive organs of the offspring, particularly the ovaries.

Fluoride interfered with the ability of ovaries to produce eggs. The mice also had fewer healthy follicles, the structures that contain the eggs.

And even worse?

Fluoride actually triggered ovarian cells to kill themselves through a process known as “apoptosis.”

In short, fluoride permanently damaged the ability of mice to reproduce… before they were even born.

So why on Earth do we keep pumping this toxic industrial waste — which is exactly what fluoride is — into our water supplies?

It’s because of intensive lobbying from dental groups.

But the moment the conversation shifted to brain development and reproductive health, these dentists were out of their depth – and it’s crazy that our politicians and health officials keep listening to them.

You know, Columbia University’s College of Dental Medicine – one of the top dental schools in America – publishes its curriculum right online.

So I decided to check it out, and see how many classes on neurology and reproductive health dentists are taking.

And, lo and behold, the number was zero.

Like I said, they need to sit this one out.

Lots of Americans are finally waking up to the dangers of fluoride. But, in many cases, their municipal governments have been very slow to listen.

Your best bet now is to protect yourself. If your community fluoridates water, consider investing in a home reverse osmosis system for your drinking water.

This is by far the most effective way to remove fluoride.

Consider it an investment in your health – and certainly the health of your grandkids.
