Vitamins D3 and K2 are crucial to ensure you remain healthy. They help promote bone and heart health and are vitamins that you should consume every day, so finding the best vitamin D3 and K2 supplements can be vital in improving your wellbeing.

Since most of our vitamin D3 comes from sunlight, many people are developing deficiencies due to the amount of time we have to spend indoors. This makes taking a D3 supplement even more critical. 

Vitamin D3 and K2 have been shown to have a synergistic relationship and work exceptionally well when taken together, compared to each on its own. 

In this article, we’ll provide a breakdown of the best vitamin D3 and K2 combination supplements on the market. We also answer some common questions posed about these supplements. 

Best Vitamin D3 and K2 Supplements – The List

1. Live Conscious – K2 + D3 (Best Overall)

Coming in as our best overall choice for K2 and D3 supplements are Live Conscious’s K2 + D3 capsules.

Each softgel tablet contains 0.125 mg of vitamin D3 and 0.1 mg of K2. These amounts are both more than the recommended daily serving of these vitamins that you should ingest, making them packed full of the essential nutrients you need. 

The type of vitamin K2 used is MK-7 and not MK-4. This in itself has its advantages and disadvantages. 

While we need both MK-4 and MK-7, research has shown that MK-7 is slightly better at promoting and creating healthy bones, as well as improving heart health.

Live Conscious K2 + D3 sells for just under $25 per bottle of 60 soft gel capsules. They also have plenty of special offers if you’re willing to buy in bulk and stock up on your supplements ahead of time.

2. Nuzena – Solar Essence Vitamin D3 K2

Not only does this supplement contain vitamin D3 and Vitamin K2, but it also has added calcium and BioPerine.

Each tablet of Nuzena Solar Essence Vitamin D3 K2 + contains 0.125 mg of vitamin D3, 0.1 mg of vitamin K2, 210 mg of calcium, and 5 mg of BioPerine.

The reason for adding calcium with these two vitamins is because it has been suggested that taking it in combination with vitamin D improves metabolic markers. 

BioPerine is also a beneficial addition, as it increases the nutrient absorption levels in your body. This helps to optimize the bioavailability of any other nutrients that you consume, making sure more of the beneficial vitamins and compounds enter your bloodstream.

Another great aspect of Nuzena Solar Essence Vitamin D3 K2 + is that it is gluten-free, sustainably sourced, and made in a facility that is approved by the FDA under CGMP guidelines, so you know the product is safe.

Nuzena Solar Essence Vitamin D3 K2 + costs about $35 per bottle of 60 tablets.

2. Onnit – Vitamin D3 Spray with Vitamin K2 In MCT Oil (Best Spray)

This combination vitamin D3 and K2 supplement comes in the form of a spray and contains MCT oil. 

In each serving, which consists of five sprays, there is 0.025 mg of vitamin D3, and 0.15 mg of K2. Both these amounts are above the recommended daily servings, providing you with adequate amounts of these vitamins.

The fact that these vitamins come in the form of a spray rather than a pill or capsule means they’re absorbed by the body much faster than any other option would be. 

Another factor that makes this spray even more bioavailable is the fact that these vitamins are transported in a base of high-quality MCT oil. Since vitamin D3 is a fat, it’s most soluble when it is ingested with a source of fat. As a result, vitamin D3 absorption in the body is boosted, so you get more of what you paid for.

This product is vegan, gluten-free, soy-free, and comes in various flavors for your pleasure. It is also small enough to carry around in your bag, and use whenever you need that extra boost of “sunshine” for an afternoon pickup.

4. Alive By Science – Liposomal Vitamin D3 & K2

Liposomal Vitamin D3 and K2 supplement contains 0.625 mg of vitamin D3 and 0.2 mg of vitamin K2. 

What we love about this supplement is that it is manufactured in such a way that liposomes engulf, and at the same time protect, the vitamin D3 and K2 while they’re ingested so they can make it through your strong stomach acids intact. This makes the active compounds of the vitamins more bioavailable, so they are more readily used by the body. 

Another factor about this supplement that really stands out is the manufacturing process. No heat or high pressure is used on the ingredients, and also goes through multiple stages of purification and filtration. 

This supplement is also vegan friendly and it doesn’t contain any ethanol, making it suitable for a wide variety of people and all manner of dietary restrictions.  

You can get a 4 oz bottle of Liposomal Vitamin D3 & K2 for less than $25. This is enough for 60 servings. Simply squirt two drops of the supplement into a glass of water each day and you’re good to go.

This supplement will provide you with adequate amounts of both vitamins, so you don’t need to worry about sourcing them from obscure and expensive fruits or vegetables.

Additionally, this supplement is formulated using coconut and MCT oil. The addition of MCT oil boosts the absorption of vitamin D3 in the body, which is beneficial, as it is more easily used. 

Not only does this supplement promote heart and bone health, but it also improves your mood and boots your immune system. It will help combat the symptoms of pesky seasonal touches of flu and will keep you feeling fit and healthy.

How We Chose Our Vitamin D3 & K2 Supplements

  • 25 brands considered
  • 142 verified reviews scrutinized
  • 36 hours of research

We ranked the Live Conscious D3 & K2 at the top of our list because we believe that the dosage of each vitamin falls into the optimum range for supplementation.

Dr Rhonda Patrick notes that studies have shown taking 1000 to 2000 IU’s of vitamin D twice per week for a month did not increase 25(OH)D levels but higher doses did have an impact.

“For example, 2,000 to 3,000 IU elicited a 7 percent increase; 3,000 to 4,000 IU elicited a 13 percent increase; and 5,000 IU elicited a 30 percent increase.

With a k2 dose of 100mg per softgel it offers a sweet spot of this fat-soluble vitamin and falls inside the range used in many studies.

  • Each Live Conscious softgel contains 5000 IU of vitamin D3 (as Cholecalciferol) and 100mcg of vitamin K2 (as Menaquinone-7)

Who Should Supplement Vitamin D & Vitamin K?

Signs And Symptoms Of A Vitamin D Deficiency 

If you have a vitamin D deficiency, there are a few signs and symptoms that you may experience. 

You might feel pain in your joints and bones, especially in your back and spine. You may experience a loss in bone mass, mood changes, muscle weakness and cramps, and fatigue. 

Other symptoms include a weakened immune system, depression, hair loss, and frequent bones fractures or splints.

Signs And Symptoms Of A Vitamin K Deficiency 

If you have a vitamin K deficiency, the main symptom you will experience is excessive bleeding. Vitamin K helps to make blood clots and prevent wounds from bleeding too much. 

You could also experience blood clots beneath your nails, easy bruising, dark stools that could contain blood, heavy menstrual cycles, bleeding from your gastrointestinal tract, or oozing from your gums and nose.

Who Is Most At Risk For Getting These Deficiencies?

Vitamin D Deficiencies

When it comes to vitamin D deficiencies, the people who are most at risk are people who are obese, people who underwent weight-loss surgeries, adults older than 55, people who spend a lot of time indoors – such as office workers -, people who have dark skin, and vegans.

If you fall into any of these categories, you might need to consider supplementing your diet to ensure that you get the appropriate amount of essential vitamins to make sure you stay happy and healthy.

Vitamin K Deficiencies 

On the other hand, infants, especially newborns, are the most likely people to be at risk for vitamin K deficiency.

Best Vitamin D3 and K2 Supplements FAQs

Do I Really Need Vitamin D3 And Vitamin K2?

Vitamin D3 and K2 are essential for healthy bones and a healthy heart.

Vitamin D3 makes the calcium in your body more easily absorbed from your bloodstream.

Vitamin K2, on the other hand, is what causes the absorbed calcium to be integrated into your bones. Vitamin K2 also prevents calcification from happening in your blood vessels, which prevents the thinning of arteries.

Without these two vitamins, calcium wouldn’t be able to do its job, and the risk for blood clotting is higher.

Why Is It Important To Take Vitamin D3 And Vitamin K2 Together?

The reason it’s important to take vitamins D3 and K2 together is the synergistic relationship between them. They work together much more effectively than each on their own.

Taking them together helps to make sure that calcium is absorbed and used faster than it would be if you just took one. 

➡️ When is the best time to take vitamin D?

Is Too Much Vitamin K2 Harmful To Your Body?

As far as research shows, not normally.

The Food and Nutrition Board of the National Academies of Medicine (FNB) sets an upper limit on vitamins, but there is no upper limit for Vitamin K2.

Vitamin K2 toxicity is extremely rare, and is most common in infants who are fed with formula, so adults shouldn’t be too worried.

The only adults who may need to be careful are those who may be on medications such as Warfarin.

This being said, it’s still important to remember that like with everything, balance is important, and too much of anything isn’t good. Try and stick to the recommended daily allowances prescribed to each vitamin, and you shouldn’t have a problem.

Why Is It Dangerous To Take Vitamin K2 If You Are Taking Warfarin?

Warfarin is a medication prescribed to thin your blood if you are at a high risk of developing blood clots.

If you take too much vitamin K2 while on Warfarin, they can work against each other. Vitamin K2 also acts to make blood clots so that it prevents wounds from bleeding excessively.

Final Thoughts

Vitamin D3 and K2 are more important than many people realize. There can be dire health consequences if you become deficient in either one, which makes monitoring your daily intake of critical importance. 

Because they directly affect your bone and heart health, it’s something you want to keep your eye on and prevent from occurring. We recommend taking the cautious route, and supplementing with vitamin D3 and K2 before you become deficient in either one of them. 

You might not be deficient but could still have lower levels of either which cause negative effects on your health.
