I’ve been taking a vitamin D supplement for many years, especially in the winter months, when I rarely get to see real sunlight.

But it’s only in the last 12 months that I have become increasingly aware of vitamin K, particularly K2.

I was working with a client who had bone density problems, and a healthcare provider and dietitian had recommended him to take a combo of K2 and D3.

As you’ll learn on this page, these vitamins have been scientifically shown to help with bone and heart health. But unfortunately, there are many supplements available that don’t provide the right forms of these vitamins.

So, we set out and tested over 30 products to come up with the following list to find the best vitamin D3 and K2 supplement.

Our best vitamin D3 and K2 supplement choice comes from Live Conscious (formerly knows as Livewell).

It may provide the right amounts with 5,000 IU per day of vitamin D and the recommended dosage of 100 mcg of vitamin K2 per serving per day.

Importantly, it’s also the vitamin K2 MK-7 type, which research has shown to be best suited to achieve healthy bones and improved heart health. [1].

  • 100 mcg vitamin K2
  • 125 mcg/5000 UI vitamin D3
Pros
  • Uses the MK-7 form of vitamin K2, which should work better for calcium absorption
  • Claims to have some added MCT oil for brain energy
  • Softgel capsules seem to be easy to swallow
  • Free from dairy, soy, and gluten
Cons
  • The bulk discounts could be a bit better

The only thing we’d like to see an improvement for is the available discounts on bulk orders of vitamin D supplements.

If capsules aren’t your thing, Double Wood Supplements D3 + K2 Liquid Drops provide an excellent way to get bone and immunity support in a single 1-ml dropper.

Each bottle contains 30 servings, and ordering through the manufacturer’s website will get you a bulk purchase discount. A “Subscribe and Save” option also offers a price break and ensures you don’t run out.

Double Wood uses MCT oil as the base for its D3 + K2 liquid drops, providing plenty of fat for absorption, allowing you to take it on an empty stomach without increasing the risk of side effects.

The liquid drops appeal to many of my clients who prefer vegan/vegetarian options.

Like their other supplements, Double Wood manufactures the D3 + K2 Liquid Drops in a GMP-certified facility in the U.S.A. The product is also soy-free, gluten-free, non-GMO, and vegan.

  • 200 mcg vitamin K2
  • 125 mcg vitamin D3
Pros
  • Bulk and “Subscribe and Save” discounts
  • Third-party tested with a moneyback guarantee.
  • No gelatin capsule means it is vegan/vegetarian friendly
Cons
  • Many user reviews about difficulty getting proper dose with dropper in the beginning

The only thing we’d like to see an improvement for is the available discounts on bulk orders of vitamin D supplements.

Nuzena is another company that has created a good quality vitamin supplement that may provide just enough vitamin D3 and K2 per day.

We liked the added black pepper extract on the vitamin K and vitamin D supplements, which may help speed up the absorption process. It allows you to reap the immune system benefits faster.

  • 100 mcg vitamin K2
  • 5000 IU vitamin D3
Pros
  • The stronger vitamin D3 dose should work well for immune function
  • Contains added calcium for bone and heart health
  • Claims to be faster to absorb due to added black pepper extract
Cons
  • It’s a bit more expensive unless you choose a bulk order

I would just recommend taking advantage of the bulk discounts to make the vitamin D3 supplement more affordable.

Buyer’s Guide

credit card and laptop

When you’re comparing different vitamin D3 and K2 supplements, it’s important to look at these three key areas.

1 - Type Of Vitamin D

Many health professionals these days suggest that vitamin D might be more important than C.

I’m not here to argue either way.

It’s probably best if you get plenty of both.

“The recommended form of vitamin D is vitamin D3 or cholecalciferol. This is the natural form of vitamin D that your body makes from sunlight.”

 

- WebMD.com

But there ‘s one important factor to consider, and that’s the specific type of this vitamin. Your body naturally produces it in the skin when exposed to UVB rays, and scientists suggest that if you don’t see enough daylight, you should aim for a vitamin D3 supplement [2].

2 - Type Of Vitamin K2

Vitamin K2

Now, when it comes to K2, it becomes a little bit more confusing.

But bear with me.

Scientists have identified two different types of K2 which you’ll generally find marked as MK4 and MK7.

The important thing to look out for is a supplement that contains the MK7 type, as studies have shown this to be significantly more effective [3].

Other studies have also revealed that large parts of the population may be deficient in vitamin K2.

Why is this?

Apparently, we don’t eat enough fermented foods, which are the main natural source of K2. More on this shortly.

3 - Compare The Dosage

You’ll notice quite different prices in the list of vitamin K and vitamin D supplements above, which is why we always suggest you compare the dosage.

Unless you have a specific health issue where a healthcare provider has recommended that you improve your essential vitamins intake by a specific amount, then there are some general guidelines you can use.

A safe amount of each would be 100mcg of K2 and 125mcg of D3 [4].

You’ll probably notice that most of the above vitamin D supplements have that ideal dosage per day to maintain optimal vitamin D levels.

Be careful not to take too high vitamin D doses than required because too much will be harmful for your body too.

Natural Food Sources

While I’m a big fan of taking vitamin D supplements to make sure you boost your micronutrient intake, it’s still a good idea to be aware of certain ways that your diet might support specific vitamin intake.

Here are some ideas you should consider.

Boosting K2 Intake

Fat-soluble vitamin K2 is only available in animal products and fermented foods, and that’s why it has become a bit more common that people don’t get the optimum levels.

“Also, because it is fat-soluble, organ meats and high-fat dairy products contain fairly substantial quantities of vitamin K-2. Conversely, lean meats, such as poultry, are not good sources of K-2.”

 

- Katherine Marengo, Registered Dietitian

With research suggesting that it could be a significant way to improve heart health, here are some vitamin K2-rich food products for a quick boost.

  1. Cooked Kale
  2. Cooked Collard Greens
  3. Raw Swiss Chard
  4. Natto
  5. Raw Spinach

 

  1. Broccoli
  2. Beef Liver
  3. Pork Chops
  4. Green Beans
  5. Kiwis

Boosting D3 Intake

First, let me say that the best way to deal with vitamin D deficiency is to get out in the sun more. Your skin naturally produces vitamin D3, and about 20 minutes without sunscreen should still be a safe solution.

But there are some ways that you might be able to adapt your diet to get a bit of a vitamin D boost.

Just keep in mind that there are very few foods that contain vitamin D, and in most cases, they contain only a small volume.

That’s why a good quality vitamin D supplement is often the recommended solution by doctors and dietitians.

Try adding some of these on a more regular basis:

  1. Beef liver
  2. Cheese
  3. Egg yolks
  4. Fatty fish (herring or sardines)

The other thing you’ll notice with these suggestions is that there aren’t any options for vegans.

And this may be a problem if you’re suffering from vitamin D deficiency.

If you are a vegan, check out our buyer’s guide on the best vegan-friendly multivitamins.

Fortunately, fortified foods and drinks are available, which may be a good option. You’ll often see this on bottles of orange juice or boxes of cereals where it might say that vitamin D and possibly calcium have been added.

You can always take dedicated vitamin D supplements if you need to speed up your intake.

Expected Health Benefits

Vitamin K2

Scientists have been studying K2 for many years, but it seems like K2 deficiency is only starting to be understood.

And here’s how it might help you.

Your body needs more vitamin D and calcium as you age because it becomes more difficult to maintain strong and healthy bones.

What K2 apparently does is help your body get the calcium to where it is needed, which is the bones.

And at the same time, it may help prevent calcium building up in arteries, which research has shown might be one of the best boosts your cardiovascular system can get.

The result could be lower blood pressure and fewer risks of developing blocked arteries [5].

Vitamin D3

bone tissues

People who become deficient in vitamin D may quickly experience quite significant issues with bone density.

Your body is perfectly able to produce enough vitamin D by being exposed to sunshine for about 10 minutes in a swimsuit.

But that’s not something most people get.

Many are concerned about direct sun exposure without sunscreen. And the winter months don’t make it easy either.

That may be the reason why so many people could have vitamin D deficiency [6].

Doctors believe that by boosting your vitamin D levels, your body may process more calcium to build up bone tissue.

The way you need to look at these two vitamins is that vitamin D may help to process more calcium, while K2 should help to prevent that calcium from becoming dangerous to your heart health.

FAQs

Should You Take Vitamin D3 With K2?

Yes, you should take vitamin D with K2. Vitamin D helps your body better absorb the calcium it needs. However, excess calcium could cause heart blockages, and taking vitamin K2 has been shown to prevent that from happening.

What Is the Best Form of Vitamin D to Take?

The best form of vitamin D to take is D3. It’s the form most closely related to the same vitamin the human body creates. And with natural sources being quite limited, it’s often best to take vitamin D3 supplements.

Does Vitamin K2 Help Clear Arteries?

No, Vitamin K2 doesn’t help clear arteries. Research on human test patients has shown that it may prevent blocked arteries, but it hasn’t been proven to help reverse the damage already done.

Can Too Much Vitamin K2 Be Harmful?

Yes, too much vitamin K2 can be harmful, especially for people with liver or kidney diseases. In these cases, patients should discuss taking vitamin K supplements with their doctor to ensure they avoid side effects.

What Is the Difference Between Vitamin K2 and Vitamin K1?

The main difference between vitamin K2 and vitamin K1 comes down to K2 preventing heart disease and K1 playing a role in blood coagulation. They are also found in very different types of foods, so you may not get both through a common source.

Who Is at Risk of D3 and K2 Deficiency?

People who don’t get enough sun exposure or who don’t eat fermented foods are at risk of vitamin D and K2 deficiency. The easiest way to solve this is through supplements, as some foods may not suit all diets.
