The formula

Four Powerhouse Ingredients

Every ingredient is selected with intention, backed by research, and tested for purity and potency.

Calcium

Calcium

Calcium is important for the development, health, and continued maintenance of bones

Vitamin D3

Vitamin D3

Vitamin D3 has long been studied for regulating calcium absorption and supporting normal immune system function.

Vitamin K2

Vitamin K2

Vitamin K2 promotes calcium accumulation in bones, while reducing its accumulation in soft tissues such as blood vessels.

Bioperine

Bioperine (Black Pepper Fruit Extract)

A patented extract of black pepper included to enhance nutrient absorption.

KEY BENEFITS

Vitamin D works better with a partner.

Vitamin D3 helps your body absorb calcium, but absorption is only half the job. Calcium still needs to reach your bones rather than settle in soft tissue like arteries. That's where vitamin K2 comes in, helping direct calcium where it belongs. Together with a base of calcium and BioPerine for absorption, this formula supports strong bones and healthy arteries in one simple daily capsule.

Frequently Asked Questions

    • How Do I Use K2+D3?
      As a dietary supplement take one (1) veggie capsule twice a day. For best results take 20-30 min before a meal with an 8 oz. glass of water or as directed by your Healthcare Professional. Caution: Do not exceed recommended dose. Pregnant or nursing mothers, children under the age of 18, and individuals with a known medical condition should consult a physician before using this or any dietary supplement.
    • What is K2 + D3?
      Vitamin K2 + D3 is a dietary supplement that pairs two vitamins your body uses together. Vitamin D3 supports calcium absorption and normal immune function, while vitamin K2 helps direct that calcium toward your bones and away from soft tissues like your arteries. Together with calcium and BioPerine for absorption, the formula supports strong bones and healthy cardiovascular function
    • Why is K2 + D3 better than just D3?
      Most diets only contain trace amounts of the critical mineral Calcium. One of the ways that Vitamin D works is by helping your body's absorption of Calcium to keep it at high enough levels throughout the body. This is great for strong tissues like bones and teeth, but it can be detrimental to soft tissues like arteries where the hardening effects of calcification can lead to other medical issues. Nevertheless, Vitamin D plays a key role in numerous aspects of basic health and is therefore one of the most important vitamins recommended by doctors for daily supplementation. A deficiency in Vitamin D causes serious problems, but having too much Calcium in soft tissues also comes with risks. For this reason, Vitamin K2 is taken in combination with Vitamin D3 to ensure that Calcium reinforces your body's hard tissues while at the same time protecting your soft tissues from calcification.
    • How do I know if I’m deficient in Vitamin D?
      Vitamin D deficiency is common; a large share of adults don't get enough, in part because it's found in few foods and is mainly made through sun exposure many people don't get year-round. The only way to know your level is a blood test, so if you're concerned, ask your doctor about checking your vitamin D status.
    • How does K2 + D3 work?
      K2 + D3 works by combining the power of Calcium, Vitamin D3 and Vitamin K2 to deliver wide-ranging health benefits available through dietary supplementation without the typical risks associated with calcification of soft tissues. Vitamin D is a vitamin that plays an important role in your health but must be modulated by Vitamin K2’s protection of soft tissues. K2 + D3 can support long-term health and vitality.
    • I have a well-rounded diet. Do I still need K2 + D3?
      A great diet definitely supports optimal health, but countless basic nutrients are not available in substantial amounts through food. For example, many vegetables are grown in soil that once had vibrant mineral profiles (including Calcium), but after centuries of agriculture the minerals have been largely depleted. For that reason and many others, dietary supplements are recommended as a simple way to boost your health.
    • How soon will it start working?
      Vitamins D3 and K2 work gradually as they become part of your everyday nutrition, not as an immediate effect you feel. Because vitamin D builds up in the body over time, consistent daily use is what matters most. Give it regular use as part of your routine rather than expecting a same-day sensation.
    • What are all the ingredients in K2 + D3?
      K2 + D3 contains four simple active ingredients: (1) Vitamin D3 as Cholecalciferol, (2), Vitamin K2, (3) Calcium Carbonate, and (4) BioPerine® to amplify the benefits of the other three compounds.
    • Can I get K2 + D3 in stores?
