What It Does

+
Formulated by Dr. Kevin Passero, Durable D3 COMPLEX is an advanced, all-in-one vitamin D formula that features an optimal dose of vitamin D3 (125 mcg / 5,000 IU) in its natural and most bioactive form. It also features a clinically proven 180 mcg dose of K2VITAL™, which provides highly bioactive vitamin K2 in the natural menaquinone-7 (MK-7) form, to enhance vitamin D’s effectiveness.*

Durable D3 COMPLEX also includes easy-to-absorb magnesium and zinc, two important mineral co-factors in bone building and calcium absorption that are required for vitamin D activation and utilization within the body. Without adequate levels of these critical co-factors, taking vitamin D may not be helpful at all. The result is a comprehensive, exceptionally bioactive and potent vitamin D supplement that provides unparalleled support for bone, cardiovascular, cognitive and immune system health.*

This synergistic combination of powerful, clinically validated ingredients:
• Supports strong, resilient bones*
• Promotes healthy bone mineral density*
• Helps inhibit calcium buildup in the arteries*
• Promotes optimal cardiovascular and cognitive health*
• Helps maintain optimal immune system function*
• Provides comprehensive health benefits in just one small capsule per day*

General Product Info:
• 30 vegetarian capsules (a 30 day supply)
• Made in the USA in an FDA inspected, cGMP facility
• Every batch is 3rd party tested for safety and purity
• Packaged in sustainable, 100% non-toxic amber glass bottles
• One-year, any reason return policy with free return shipping

Why It Works

+
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. 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.*

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.*

Synergistic Mineral Co-Factors Unlock Vitamin D’s Full Benefits for Maximum Bone & Heart Health Support
In addition to vitamin K2, this all-in-one formula is enhanced with two critical, synergistic mineral co-factors, magnesium and zinc, which are required for vitamin D absorption and activation within the body.*

Durable D3 COMPLEX is made with premium, easy-to-absorb citrate forms of magnesium and zinc to help ensure maximum effectiveness.*

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.*

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 people’s 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 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.*

The Doctor Behind The Formula

Dr. Kevin Paserro Answers Your Questions

Is taking a high-potency dose of vitamin D daily safe?

+

The latest research shows that, even though vitamin D is a fat-soluble nutrient, a daily dose of 125 mcg (5,000 IU) is appropriate and beneficial for most people.*


Why is Vitamin D3 superior to Vitamin D2?

+

Vitamin D2 (ergocalciferol) is a synthetic form of vitamin D and the form often used to fortify foods. It’s also the form you’re likely to get if your doctor gives you a prescription for vitamin D. It has been shown to be significantly less absorbable—and less effective—than vitamin D3 (cholecalciferol).*

Vitamin D3 is the type your body produces naturally in response to exposure to sunlight. Studies have shown that D3 is much more absorbable than D2. In fact, one study found that it raised and maintained blood levels of vitamin D 87% better than D2 and produced a 2 to 3-fold increase in storage of vitamin D in the body.*


When is the best time to take Durable D3 Complex?

+

Vitamin D is fat-soluble and can be taken with or without food, but it's best absorbed when taken with a meal or snack that contains some fat. You can take vitamin D at any time of day. There’s not a time that’s considered “better” than others, but consistency is key, so find what works for you—whether that’s taking it with your breakfast or bedtime snack—and be consistent.*


Can I take more than the recommended dose?

+

Do not exceed the recommended dose of 1 capsule per day unless you are directed to do so by your healthcare practitioner. Since this product contains vitamin D at a level that exceeds the adult tolerable upper intake level, it is highly recommended that you work with your doctor to have your serum 25(OH)- and 1,25(OH)2-vitamin D monitored every 60-90 days while consuming this product to ensure that your vitamin D levels remain in an acceptable range.*


Are there any side effects?

+

There are no significant known side effects associated with taking vitamins D3 and K2. If you are taking blood thinning medication, check with your doctor about taking supplements that contain vitamin K.*

In addition, we highly recommended that you have your vitamin D levels checked periodically while taking this product to ensure that your levels remain in a healthy range.*

Pregnant or nursing women should always consult with their healthcare provider prior to using any supplements.*


Are there any other Durable products I should consider when it comes to supporting my heart and cardiovascular health?

+

Our bestselling Durable HEART® formula offers clinically proven natural support for healthy cholesterol levels, while Durable BLOOD PRESSURE® helps balance blood pressure naturally.*

Research shows that magnesium is an essential nutrient for cardiovascular health, so you might want to consider adding Durable MAGNESIUM® to your regimen for extra support.*

In addition, our Durable CoQ10® formula provides an extra-strength dose of this critical cardiovascular nutrient in an industry-leading, crystal-free form, delivered as a softgel for maximum absorption.*

If you have severe or stubborn cholesterol issues, including genetically high cholesterol, consider Durable HEART PLUS®. This money-saving bundle combines Durable HEART with Durable RED YEAST RICE. You can save up to $30 per 1-month supply vs. buying 1 bottle of each product separately. Since these two formulas help lower dangerous LDL cholesterol via different mechanisms of action, combining them can produce remarkable and comprehensive results.*


What is the Nuflow Complex that is listed in your Other Ingredients?

+

Nuflow is a natural filler and flowing agent made from the outer hulls of rice. Flowing agents are used in the production of all encapsulated or tableted supplements to help prevent the ingredients from clumping as they flow through the encapsulating machinery. Most companies use synthetic flowing agents like silicon dioxide, magnesium stearate, talc or steric acid, which can potentially inhibit the absorption of the active ingredients or may be potentially harmful.*
