Ouro D3

While Vitamin D3 is now one of the most well-known immune boosting supplements, most company’s leave out one crucial ingredient, vitamin K2. Because vitamin D increases the absorption of calcium in the body.

Without Vitamin K2, the body cannot direct calcium to the bones where itʹs needed; instead,  the calcium resides in soft tissue like the arteries. That’s why Ouro D3 contains a powerful combination of 5,oooIU of vitamin D3 and 100mcg of vitamin K2.

The Truth About

Vitamin D

I’m sure you’ve heard about the health benefits of Vitamin D before …

And you may even take a daily Vitamin D supplement.

But what you probably didn’t know is …

While most scientists and health professionals call it a vitamin …

Vitamin D is NOT really a vitamin at all.

The active form of Vitamin D in your body …

Called Calcitriol

Is a powerful steroid hormone with receptors on nearly every cell in your body. 

In fact, scientists believe it could be responsible for affecting up to 2,000 different genes in your body (that’s nearly 1/6 of the active genome)!

Making Vitamin D essential for nearly every major biological system in your body.

Which is why Vitamin D deficiency has been linked to a whole host of health issues

Weak Immune System

Ever wonder why more people get sick in the winter? Low sunlight exposure leads to low Vitamin D production in the body … and Vitamin D is essential for helping your body activate it’s killer T-cells. In fact, one study out of the British Medical Journal showed that boosting your Vitamin D to normal levels reduced the odds of respiratory infection by a whopping 42%!

Increased risk of Hospital Infections

Researchers from the University of Colorado discovered that hospital patients with low levels of Vitamin D had double the risk of severe sepsis

Mitochondrial Damage

A study out of New Castle University showed that low Vitamin D levels were directly linked to poor mitochondria function … which caused extreme fatigue and poor recovery in the muscles.

Weak Brittle Bones

Vitamin D helps your body absorb more Calcium into your blood by activating receptors in your gut. A study of over 5,000 men showed a direct correlation between low Vitamin D and low Bone mineral density … the most common measurement of bone strength.

Erratic Blood sugar

Vitamin D directly triggers your body to produce more insulin and also acts on fat and muscle cells to control insulin resistance. One study out of Harvard showed individuals with the highest Vitamin D levels were twice as likely to maintain healthy blood sugar levels.

Abnormal Blood Pressure

One study showed that people who live farther from the equator (receiving less light exposure) had a higher risk of elevated blood pressure. And another study showed that people naturally had higher blood pressure levels during winter months vs summer months.

Even worse, multiple studies have linked low Vitamin D levels to America’s #1 silent killer.

Vitamin D And Your Heart

You see, at birth, your arteries and veins start out healthy and clean.

They are able to feed your heart, brain and every other organ and cell in your body without any obstructions.

But as you get older, rogue calcium molecules start to combine with cholesterol molecules …

Forming a sticky substance doctors call plaque …

That builds up along the walls of your circulatory system.

Year after year these plaque deposits grow thicker, making your arteries “stiff” …

And if left unchecked, these blockages can lead to dangerous heart issues.

In fact, new research revels that the coronary calcium score may be an even bigger predictor of future heart issues than cholesterol. 

Which is why Vitamin D is so crucial for heart health …

Because Vitamin D helps activate a unique pathway in the body I call the “biomatrix” switch …

Because it shuttles these rogue calcium molecules away from your arteries and veins …

And into your bones where it’s needed the most.

In fact, this “biomatrix” switch is so essential for your heart health …

One study from the American Heart Association noted that individuals with low Vitamin D levels had 3x the risk of heart disease. 

And another study out of Harvard Medicine noted that restoring normal Vitamin D levels could cut your risk of heart problems in half! 

With all these issues related to low D levels …

It’s easy to see why everyone should be taking at least 5,000 IU’s of Vitamin D3 a day …

Like we offer in our brand new Ouro D3 blend.

Especially because D3 is the compound your skin cells make when they are exposed to light from the sun …

And numerous studies show that D3 is much more effective and bio-available than the cheap D2 you find in many other fortified foods and supplements.

But as I’m about to show you …

Taking Vitamin D3

Is NOT Enough

Especially when it comes to heart and bone health.

Because emerging research shows if you want to fully activate this “biomatrix switch” … And flush decades of dangerous plaque buildup clean out of your arterial walls …

It’s critical that you get enough Vitamin K2 in your diet.

Unfortunately, K2 is almost completely absent from today’s standard American diet.

And the Vitamin K that’s added to packaged foods is mostly the weak ineffective K1.

Which is A Shame...

Because numerous studies show that high levels of K2 can help:

A study of 244 Dutch individuals showed that K2 supplement significantly improved the flexibility of the arteries (reduced stiffness)

One study our of Rotterdam of over 4,000 individuals showed that higher levels of Vitamin K2 cut the risk of heart trouble by as much as 50% and all-cause mortality by up to 25%.

A study in the journal, Nutrition, showed that daily supplementation with Vitamin K reduced the risk of erratic blood sugar by 51%.

A study of 241 patients revealed that supplementing with a small amount of K2 helped maintain bone density as we age … and reduced the risk of fractures by 65%.

This is a Must if You Have Any of These Risk Factors

In fact, if you have any combination of these risk factors … I can almost guarantee your most likely deficient in this critical hormone.

Your Questions Answered

Is Vitamin K2 Really That Important to Take With Vitamin D?

If we had to choose between taking vitamin D alone or none at all, we would choose to take none – that’s how important K2 is.

You see, vitamin D increases the absorption of calcium in the body. 

Without Vitamin K2, the body cannot direct calcium to the bones where itʹs needed; instead,
the calcium resides in soft tissue like the arteries! 

If I Can Get Vitamin D From The Sun, Why Don't I just Walk Outside?

The recommended 30 minutes of sunshine, which produces optimal amounts of vitamin D, is produced only in summer with total body exposure (naked!)…

And only from the hours of 10AM to 3PM.

Meaning, in order to keep your vitamin D levels optimized…

You either need access to a nude beach during your lunch break…

Plus, live somewhere where it’s summer all year round.

Or, simply take a natural vitamin D supplement like Ouro D3 every morning. 

What About Vitamin K2? Can't I Get Enough From My Diet?

In the western world, vitamin K2 is rarely found in the foods we eat. The most abundant sources of K2 come from fermented foods like the soy derived NATTO. Unless you’re eating a diet heavy in fermented Asian foods, a K2 supplement is strongly recommended.

How Long Will One Bottle of Ouro D3 Last?

One bottle of Ouro D3 contains 60 capules. The recommended dosage is one capsule a day, which provides you with a full two month supply.

What's in Ouro D3

Vitamin D3 Label 6x2.75
