Should You Take Vitamin K2 With Vitamin D???


Vitamin D has been in the news for the past several years and has seen many studies reflecting it’s tremendous health benefits. News articles such as “Vitamin D Vital for the Heart”, “Sunscreens can Block Vitamin D”, Vitamin D Deficit in Pregnancy Tied to Caesarean Risk”, and “Lack of Vitamin D Can Double Your Risk of Stroke” are just a few of the headlines by some of the major news networks.

Vitamin D Deficiency

More than1 billion people worldwide do not consume adequate amounts of vitamin D and more than 50% of postmenopausal women taking meds for osteoporosis have suboptimal levels of vitamin D. Without adequate levels of Vitamin D, only 10 -15% of our dietary calcium can be absorbed. This is due to the function of the Vitamin D to facilitate the absorption of Calcium.

Vitamin D

Vitamin D is a fat-soluble vitamin/hormone and is obtained in three ways:

  1. Dietary Intake
  2. Supplementation
  3. Sunlight


Vitamin D is naturally present in very few foods, added to others, and available more readily as a dietary supplement. It is also produced endogenously, within the body, when ultraviolet rays from sunlight strike the skin and trigger vitamin D synthesis. Vitamin D obtained from sun exposure, food, and supplements is biologically inactive and must undergo two hydroxylations in the body for activation. The first occurs in the liver and converts vitamin D to 25-hydroxyvitamin D3. The second occurs primarily in the kidney and forms the physiologically active 1,25-dihydroxyvitamin D3.

Role of Vitamin D

  • Promotes the proper synthesis and functioning of important proteins essential for proper calcium utilization
  • Supports the maintenance of bones
  • Supports immune health
  • Helps maintain cardiovascular health
  • Helps maintain normal blood pressure

Why Vitamin K2

Vitamin K is also a fat-soluble vitamin, so it is stored in the body’s fat tissue and liver. It is best known for its role in helping blood clot (coagulate) properly (the “K” comes from its German name, Koagulationsvitamin). Vitamin K also plays an important role in bone health by binding calcium and other minerals to the bone.  Vitamin K is used to reduce the risk of bleeding in liver disease, malabsorption syndromes, or in association with long-term use of antibiotics. Most importantly it is needed for proper use of calcium in bones. Higher vitamin K levels correspond to greater bone density, while low levels of vitamin K have been found in those with osteoporosis. There is increasing evidence that vitamin K improves bone health and reduces risk of bone fractures, particularly in postmenopausal women who are at risk for osteoporosis. In addition, studies of other groups (such as male and female athletes) have also shown bone enhancing benefits from vitamin K supplements. Vitamin K may very well end up being as important for you as vitamin D, as research continues to illuminate the growing list of its benefits for your health. Vitamin K is probably where vitamin D was ten years ago, with respect to its appreciation as a vital nutrient that has far more advantages than originally thought.

Purpose of Vitamin D and K as Supplements

Most people are deficient in Vitamin D or at least insufficient as it relates to their diet and sun exposure. Keep in mind that Vitamin K is responsible for healthy tissues. In bone, it activates osteocalcin, a protein required to bind calcium to the mineral matrix, thus strengthening the skeleton. In circulation, Vitamin K2 participates in carboxylation of Matrix Gla Protein (MGP), the most potent inhibitor of arterial calcification known, lowering the risk of vascular damage. Therefore there is a compounding effect of these two vitamins working together.

What to Look for in a Good Supplement

Vitamin D3: 5,000IU

Vitamin K2: 45mcg
