About D3+K2

D3 and K2 work together to keep calcium away from your arteries and in your bones where it belongs. I’m sure you know how important calcium is for bone health. But here’s a surprising fact your doctor may not have told you: As you get older, your body gets worse at putting calcium in your bones where it belongs.

So instead, it gets directed into your arteries.

What’s the solution?

In order to help keep your arterial calcium at healthy levels, your body has its own natural defense called Matrix GLA Protein (or MGP) to guard them. But…your body must activate MGP in the first place…otherwise your arteries remain defenseless!

What does this? Vitamin K2, which is the first nutrient in this combination.

However, things don’t end there. The calcium must end up in bones where it belongs. For this to happen, your body needs something called osteocalcin to signal for your bones to absorb calcium and create new bone tissue.

What’s crucial for creating osteocalcin? Vitamin D3, which is the second nutrient in this combination.

That’s why you need a combination of K2 and D3. Your arteries stay more flexible and youthful…while your bones remain stronger!

We don’t just rely on our manufacturer’s word, though. Our quality assurance manager has personally visited each manufacturer to make sure that they meet GMP requirements, and yearly audits are performed to ensure they continue to adhere to GMPs.

And finally, before any batch of product is released for distribution, we examine the product and review the product testing and certificates of analysis to ensure that it all meets our specifications.
