Did you know most vitamin D supplements DON'T WORK because they fail to include a crucial second ingredient – vitamin k2?

Ouro D3 contains both at their optimal doses and in their most bioavailable forms to help:

WARNING: Research shows vitamin D levels can plummet over 50% during the winter. Restore your levels today!

7 Reasons Vitamin D

Is Crucial for Men

Low Testosterone

Vitamin D is responsible for over 2,000 genes in your body…among those genes are the ones responsible for testosterone production. In one study published in the Central European Journal of Urology…

Researchers compared the hormonal profiles of 80 men in summer VS winter and found testosterone levels plummet by 31% in winter! These weren’t old broken-down test subjects in poor health either.

No, this study used healthy, young men between the ages of 20-35. So if you ARE older, you can only imagine how much more your testosterone levels probably dropped this past winter.

The researchers found the test subjects sex drive was almost 40% lower in the winter…and their sex life dried up like a desert well. In fact, during the winter these men had 67% LESS orgasms. Thankfully, supplementing with Vitamin D is show to increase testosterone levels by 30%!

Week 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 the body activate it’s T-cells.

In fact, one study out of the British Medical Journal showed that boosting Vitamin D to normal levels reduced the odds of respiratory infection by a whopping 42%!

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 risk of heart problems in half! ​

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.​

Brittle Bones

Vitamin D helps the 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 the 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.

Chance Your Levels Are Low!

If men have any combination of these four factors … we can almost guarantee they’re most likely deficient in vitamin D and need to supplement.

Vitamin D Alone Is Not Enough

Current research shows the important synergistic relationship between Vitamin K2 and Vitamin D3.

Taking Vitamin D3 with Vitamin K2 helps to ensure the calcium transported by the Vitamin D is absorbed by your bones where it's needed, rather than accumulating in deposits in your arteries.

Which is why Ouro D3 contains 100mcg of the highly bio-avaible form of vitamin k2 -menaquinone-7...

Along with 5,000 IUs of the highly bio-availabe form of Vitamin D3 - cholecalciferol.

Plus, Vitamin K2 Has It's Own Potent Benefits for Men

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 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%.
