Researchers are discovering that Vitamin D may be the most important nutrient ever discovered for supporting immune health.*

Regulating the expression of more than 900 genes in your body, vitamin D3 influences just about every function, including healthy cell development and growth, strong bones, cardiovascular health, brain health and cognition.* However, supplementing with just vitamin D isn’t enough.

When you take vitamin D, it is vitally important to also get enough vitamin K2. Not only do the two vitamins work synergistically, vitamin D needs vitamin K2 to function properly. Taken together, vitamins D3 and K2 support your overall heart health, arteries and veins, bone health, and respiratory and immune systems.*

Vitamins D3 & K2:

  • Supplies 5,000 IU of Vitamin D3, the optimal level providing an effective daily dose for many individuals.
  • Provides 180 mcg of vitamin K2 as MenaQ7®, the optimal level of K2 in the only patented, clinically supported form on the market today to promote healthy, flexible arteries and overall heart health, as well as bone health.*
  • Utilizes vitamin K2 produced from chickpeas, which has been proven to be one of the most bioavailable, stable and beneficial varieties.*
  • Is soy-free to avoid potential allergen concerns.
  • Uses only non-bioengineered (non-GMO) ingredients
  • Comes packed in vegetarian-friendly capsules.
  • Is free from magnesium stearate, a questionable ingredient added to many supplements to enhance product flow but doesn’t provide any nutritive benefits.

With our Vitamins D3 & K2 formula, you get optimal absorption in an easy-to-take, one-a-day capsule serving, unlike some other formulas with MK-4.

Many people have low levels of vitamin D – don’t be one of them. Help safeguard your health, and order Vitamins D3 & K2 today.

  • Too many IU's for me

    I love this product but wish they would make a 2000 iu dose with the K2. I cannot take large doses of vitamin D because it affects my digestive track (need I say more). I would really rather purchase my D3 from Dr Mercola.

    Dr. Mercola's Vitamin D3 w/ K2 is the best on the market I feel. Our whole family takes it. A very important supplement especially at this time!

  • Ideal D3/K2 ratio

    This is so far my favorite D3 and K2 supplement. I was reviewing my supplements with my biological dentist and he was really impressed with this product. He said this is the ideal amount of D3 and K2 that the average person should be taking daily. I also take the formula that has the calcium in it and like that as well.

  • VitD3 with VitK2

    I have been buying this product for years but I have just realised that it has maltodextrin in it, why? I’m so disappointed.

  • Was this review helpful?
    • Customer Support

      There is a minuscule amount of maltodextrin contained in this product, and the benefit of the supplement outweighs any potential damage from the maltodextrin within. The intake will be negligible and likely to be insignificant compared to other sources already consumed. Maltodextrin acts to support and stabilize the vitamin D in this product.

  • D3 & K2 vs Liposomal D?

    I LOVE Mercola products as it takes the guesswork out of taking supplements. I completely trust Dr. Mercola! My question is why doesn't the Liposomal D have K2? I take the D3 with K2 but thought about switching over to the Liposomal D but don't want to miss out on the K2 benefits.

      We thank you for your review on the Vitamin D3 & K2. Vitamin K2 is omitted from the Liposomal Vitamin D, as this Vitamin K is considered a natural blood thinner and was left out of this product to make sure it was available to as many people as possible. We hope you find this helpful!

  • Question -Warning

    I read on other sites that sell this product ( Mercola vit D3 and K2) that if you take blood thinners, you should not take this product. Is that true? I did not see that warning on your website.

  • Curious

    After reading so many Mercola articles slamming the use of fructose and all of its derivatives, why do so many of the supplements have sucrose ("...sucrose is 50% fructose.") added to the formulas? What possible enhancement could that be? Either it's as deadly as described or it's not. "...sucrose is 50% fructose."

  • Was this review helpful?
    • Customer Support

      We understand any concerns you may have regarding the Sucrose in this product. The modified food starch helps act as a base to stabilize the consistency and provide a platform for the Vitamin D so it can be properly absorbed. The Sucrose acts to support and stabilize the Vitamin D as well. Only minor amounts of this ingredient is present in the product.

  • Quality product

    I have been using Mercola products for a couple of years now. I began visiting a hormonal health/naturopathic clinic for menopausal symptoms and after all of the testing, they suggested a supplement regimen and asked what brand I'm currently using. When I told them Mercola, they were satisfied and confident with the quality. They never ask me to switch to the brands they carry. That is all I need to hear!
