The Science
+
According to Dr. Passero, the importance of vitamin D in terms of your overall wellness and vitality cannot be overstated.*
With its ability to regulate over 1,000 genes in the human body, vitamin D influences just about every aspect of your health. It plays an integral role in building strong bones, maintaining cardiovascular and cognitive health, and regulating your immune system.*
Despite vitamin D’s importance, a large percentage of adults (up to 50% by some estimates) are deficient, which is why supplementing with a high-potency vitamin D supplement is so important. Durable D3 COMPLEX features 125 mcg (5,000 IU) of bioactive vitamin D3. The natural D3 form has been shown to be up to 87% more effective than the synthetic D2 form at raising blood levels of vitamin D. Unfortunately, many inferior vitamin D supplements as well as foods fortified with vitamin D are made with this synthetic form.*
How Vitamin D and Vitamin K Work Together to Keep You Healthy
When you take supplemental vitamin D, it’s important to make sure you’re also getting enough vitamin K. That’s because increasing levels of vitamin D in your blood typically increases calcium levels too, and you need vitamin K to help activate hormones and enzymes that make sure the calcium ends up in your bones where it belongs—instead of in your arteries, organs or other soft tissue.*
There are two primary forms of vitamin K, and it’s important to make sure you are getting adequate amounts of both in your diet. Vitamin K1 is the most common form of vitamin K found in food, primarily in leafy green vegetables. Vitamin K2 (also known as menaquinone) however, is typically found only in certain animal-derived and fermented foods that are largely missing from the modern diet, which makes K2 supplementation critically important.*
K2VITAL™ Goes Above and Beyond Other Forms of Vitamin K2
Durable D3 COMPLEX provides a powerful 180 mcg dose of highly bioactive K2VITAL™ vitamin K2 in the superior, all-trans menaquinone-7 (MK-7) form. K2VITAL™ is made with unique micro-encapsulation technology that stabilizes the seven double molecular bonds (the “7” in MK-7), resulting in a molecule with all trans isomers (the biologically active form in humans). While many supplements are made with inferior, unstable forms of MK-7 or the less effective MK-4, K2VITAL™ goes above and beyond other vitamin K2 ingredients to offer unmatched stability, purity, bioavailability and effectiveness.*
At the potent, clinically validated 180 mcg dose found in Durable D3 COMPLEX, vitamin K2 as MK-7 has been shown in multiple research studies to help increase bone mineral density and keep arteries healthy and pliable. Taken together, vitamins D3 and K2 have been shown in numerous clinical studies to support healthy bone mineralization, a healthy cardiovascular system, optimal immune function and a higher overall level of wellness.*
Mineral Co-Factors Provide Synergistic Bone & Heart Health Benefits
In addition to vitamin K2, this all-in-one formula is enhanced with two synergistic mineral co-factors, magnesium and zinc, which are involved in maintaining healthy bone mineral density as well as cardiovascular health. Magnesium helps to ensure that calcium is deposited in the right places, transporting it across cell membranes and into bone tissue. Zinc is involved in the synthesis of collagen, a protein that supports the structural integrity of bones, and, like magnesium, is essential for proper bone mineralization, helping to build strong, healthy bones. Durable D3 COMPLEX is made with premium, easy-to-absorb citrate forms of magnesium and zinc for maximum effectiveness.*
If you’re looking for an advanced, expertly formulated vitamin D formula that will help you get the most out of what vitamin D supplementation has to offer for bone health, cardiovascular and cognitive wellness, immune support and more, look no further than Durable D3 COMPLEX.*
