How does fluoride affect children's IQ?

Dr. Nathan Bryan 0:00
People with bleeding gums, poor oral hygiene, had higher heart attacks and strokes. So the solution back then, well, let's kill all the bacteria.

Why is fluoride considered a neurotoxin?

Dr. Nathan Bryan 0:06
But now fast forward 100 years, we know that there's a microbiome. There's bacteria that live in the mouth, on the skin, in the gut.

What is the link between fluoride exposure and IQ reduction?

Dr. Nathan Bryan 0:11
And if we kill these good bacteria, it causes systemic disease. So we know better and we got to do better.

How does the oral microbiome influence brain health?

Dr. Nathan Bryan 0:16
But yet two out of three Americans still use mouthwash. Probably 99 out of 100 people are using fluoride in their toothpaste.

What are the concerns regarding mouthwash use?

Dr. Nathan Bryan 0:21
And it's causing complete dysbiosis. Fluoride's a neurotoxin, decreases IQ in kids by as much as seven points. There's no benefits.

How does fluoride in water compare to fluoride in toothpaste?

Dr. Nathan Bryan 0:28
It's all risk.

What should parents consider when choosing toothpaste?

Dr. Nathan Bryan 0:28
So get rid of it.
Sean Kelly 0:35
All right, guys, here at A4M, we got Dr. Nathan Bryan. It's been almost two years since you came on, I think.

What actions can parents take to protect their children's health?

Sean Kelly 0:40
Is that right?
Dr. Nathan Bryan 0:40
Crazy, right?
Sean Kelly 0:41
Time flies. Time flies. You got a book now, man. You're an author. Congrats.
Dr. Nathan Bryan 0:45
Fifth book, I think, but that's the latest.
Sean Kelly 0:47
Wow. What was the inspiration for this one?
Dr. Nathan Bryan 0:49
You know, really to bring people up to date on the science of nitric oxide. So this book, it tells the story of nitric oxide, what it is, how it's produced, why people should be concerned with it. But it's not just a scientific book, but it kind of interlays my personal journey, who I am, my personal journey of discovery, and then how we've been able to take the science of nitric oxide and translate that into clinical medicine, product technology that actually restores the body's ability to make it.
Sean Kelly 1:16
Yeah, when I think of nitric oxide, I literally picture your face now. Oh, do you?
Dr. Nathan Bryan 1:20
That's how like... Well, my PR and media and agents are doing a good job then.
Sean Kelly 1:26
That's how I feel like you've positioned yourself when people think of nitric oxide though.
Dr. Nathan Bryan 1:30
Well, look, I spent 25 years in academia. I mean, I spent my entire adult career studying this single molecule. And, you know, I've always believed that to be successful, do one thing and do it better than anybody else in the world. So that's what we've done.
Sean Kelly 1:43
Yeah. Any new studies or things since the last time you came on in regards to nitric oxide?
Dr. Nathan Bryan 1:48
Well, we're moving the field forward. We've got drugs now for heart disease that we're developing through the FDA. We've got a drug for Alzheimer's, which I'm convinced will completely eradicate Alzheimer's, our nitric oxide drug therapy. Wow. Because Alzheimer's is a vascular metabolic disease that leads to protein misfolding. So it's hypoperfusion of the brain. It's insulin resistance in the brain, which we call diabetes type 3. And what does nitric oxide do? It dilates the blood vessels. It improves glucose uptake. It improves mitochondrial function. When you get the cells of the brain, the oxygen, the nutrients, and activate their mitochondria, then you don't get misfolding of proteins and you don't lose cognition.
Dr. Nathan Bryan 2:25
That's very interesting. That's what nitric oxide does.
Sean Kelly 2:27
Because they say Alzheimer's starts when you're very young, right? Like you start building it up in your 20s and your 30s.
Dr. Nathan Bryan 2:32
Well, I mean, there's risk factors. So everything that we know, risk factors that are associated or lead to a loss of nitric oxide production increase your risk for developing dementia and Alzheimer's. So what is that? High blood pressure, erectile dysfunction, smoking, poor diet, sedentary lifestyle, all those decrease nitric oxide production. The end result is lack of blood flow, insulin resistance, and then eventually Alzheimer's.
Sean Kelly 2:56
Yeah. You're seeing a lot of Alzheimer's and a lot of erectile dysfunction too these days.
Dr. Nathan Bryan 3:00
Yeah, so erectile dysfunction precedes dementia and Alzheimer's. Oh, it does? So it's like a... Yeah, it's what we call the canary in the coal mine, because think about it. Erectile dysfunction is the lack of the ability to dilate the blood vessels of the sex organs. So when we need to recall memory or have some executive function, we've got to dilate, we've got to perfuse certain regions of the brain. So if you can't dilate the blood vessels of the sex organs when you're going to have sex, then you can't, that same dysfunction occurs in the brain, in the cerebral organs.
