Durable D3 + K2 COMPLEX

Why It Works

According to Dr. Passero, the combined role of vitamins D3 and K2 in supporting overall health and vitality cannot be overstated.

With its ability to regulate over 1,000 genes in the human body, vitamin D plays a central role in building strong bones, maintaining cardiovascular and cognitive health, and regulating your immune system. However, vitamin D does not work in isolation. Vitamin K2 is essential for directing calcium into the bones—where it belongs—while helping maintain clear, flexible arteries.

Despite the importance of this relationship, a large percentage of adults (up to 50% by some estimates) are deficient in vitamin D, and many are not getting adequate vitamin K2—making comprehensive D3 + K2 supplementation essential.

Durable D3 + K2 COMPLEX features 125 mcg (5,000 IU) of bioactive plant-based vitamin D3 derived from lichen—paired with a clinically validated dose of vitamin K2 to support optimal calcium utilization and whole-body health.

This 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 the synthetic D2 form.

Lichen-Sourced Vitamin D3 Offers Superior Purity and Sustainability (125 mcg / 5,000 IU)
Unlike conventional vitamin D3, which is typically derived from lanolin (a highly processed crude fat extracted from sheep’s wool), lichen-sourced D3 is 100% plant-based, making it a cleaner, more sustainable and vegan-friendly alternative.

Lichen grows in some of the most pristine environments on Earth, free from the pesticides, detergents, chemical solvents and other contaminants associated with lanolin extraction. Lichen naturally produces highly bioavailable vitamin D3 (cholecalciferol), the most effective, bioactive form for raising and maintaining optimal D levels in the body.

Whether you’re following a plant-based lifestyle or simply looking for a purer source of vitamin D3, lichen-derived D3 offers the cleanest, most ethical choice—without compromising effectiveness.

How Vitamin D and Vitamin K Work Together to Keep Your Heart & Bones Healthy
When you take vitamin D on its own, it increases calcium absorption in the body. That’s why 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 (180 mcg)
Durable D3 + K2 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 that remains biologically active longer than any other form of vitamin K.

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 + K2 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 form a highly synergistic system shown in numerous clinical studies to support healthy bone mineralization, a healthy cardiovascular system, optimal immune function and a higher overall level of wellness.

Synergistic Mineral Co-Factors Unlock Vitamin D’s Full Potential
In addition to vitamin K2, this all-in-one formula is enhanced with two critical, synergistic mineral co-factors, Albion® magnesium di-malate and Albion® zinc bisglycinate. Magnesium and zinc are required for vitamin D absorption and activation within the body.

Durable D3 + K2 COMPLEX is made with Albion® premium, easy-to-absorb forms of magnesium and zinc to help ensure maximum effectiveness. Albion® minerals are the gold-standard for quality and among the only varieties produced in the U.S.

Magnesium Activates Vitamin D and Guides Calcium Where It’s Needed (50 mg)
Magnesium, an essential mineral involved in maintaining healthy bone mineral density and cardiovascular health, helps ensure that calcium is deposited in the right places, transporting it across cell membranes and into bone tissue.

Magnesium also is one of the most important co-factors needed to activate vitamin D in the body. The enzymes that metabolize vitamin D all seem to require magnesium to function properly, which means that if your magnesium level is too low, your body cannot activate or process vitamin D.

Zinc Supports D3 Absorption, Bone Strength and Collagen Formation (5 mg)
Similarly, your body needs adequate levels of zinc in order to absorb and properly utilize vitamin D. Zinc plays a major role in the regulation of vitamin D receptors within the body, so if your zinc levels are low (which many peoples are), you won’t get the full benefits of vitamin D supplementation.

Zinc is also 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.

If you’re looking for an advanced, expertly formulated D3 + K2 formula that will help you optimize your bone health, cardiovascular and cognitive wellness, immune support and more, look no further than Durable D3 + K2 COMPLEX.
