Vitamin K2 is one of those supplements that most people still haven’t heard enough about. My dietitian and nutritionist have insisted on it for years, and my own research has shown me that it should be on a supplement stack for every athlete.
But just like with all vitamin products, there are plenty of low-quality brands out there that you want to avoid.
So, I spent two months with my dietitian and a dozen clients researching and testing over 40 different products to come up with this list of the best vitamin k2 supplements.
Our Top Vitamin K2 Supplements (September 2023)
1 - Live Conscious K2+D3 (Editor's Choice)
Out of all the vitamin K2 supplements we tested, this Live Conscious one came at the top, primarily for the dosage and combination with vitamin D3.
During the time I was testing it, I didn't experience any side effects or stomach upset, and none of the rest of the testing team had an issue either.
My dietitian also highlighted that the dosage of vitamin K2 and D3 are great for improving bone density and preventing cardiac issues [1].
Quick Facts:
- Vitamin D3 : 125 mcg
- Vitamin K2 MK-7 : 100 mcg
- Large dose of vitamin D3 for great immune and bone health benefits
- Provides the more bioavailable type of vitamin K2 to help keep blood vessels healthy
- Available with great bulk order discounts and subscription offers
- Comes In easy-to-swallow soft gel capsules
- It’s not certified for vegan use due to gelatin content
2 - Nuzena Solar Essence Vitamin D3 K2
Nuzena is a well-known brand in the dietary supplements space, and the company has put together a great mix of vitamins and minerals. What I liked about this product is that it also combines vitamin K and D for improved heart health [2].
And for healthy bones, calcium is added into the formula of the vitamin K2 supplement to have all the ingredients to support maintaining optimum bone growth.
Having taken this product for over a month now, I can also say that there don’t seem to be any side effects like stomach upset.
Quick Facts:
- Vitamin D : 5,000IU
- Vitamin K2 Mk-7 : 100 mcg
- Calcium : 210 mg
- Black Pepper Extract : 5 mg
- Includes vitamin D3 for added immune and bone health
- Added black pepper extract helps with speeding up the absorption
- Available with great subscription discounts for regular intake
- No bulk order offers are currently available
3 - Vitamin D3 + K2 Liquid Drops
This is the first liquid vitamin K2 supplement that we encountered, and based on the research from my dietitian, it provides a great source of both vitamin K2 and D3.
Both of these are included in more than the daily need to ensure you gain as many benefits as possible.
I used this for several weeks by adding a drop along with some other powdered vitamins to my green smoothie, and it seems to work great.
Quick Facts:
- Vitamin D3 : 125 mcg
- Vitamin K2 MK-7 : 200 mcg
- Comes in a convenient liquid form that you can mix in with a morning smoothie
- Provides more than the daily need for vitamin K2 and D3
- Vegan certified option and non-gmo
- Measuring an exact dose can be a bit tricky with the dripper
4 - Thorne Vitamin K
Based on our research and testing, Thorne is one of the best vitamin K2 supplement products available because it has a great balance of the two forms of K2 plus some added K1.
That combination seems to be ideal for bone health and improved cardiovascular health [3].
The overall dosage also seems to be in line with recommendations from dietitians, and I like that the capsules are small and easy to swallow. But keep in mind that other products offer a stronger dose at a better price.
Quick Facts:
- Vitamin K2 MK-4 : 5 mg
- Vitamin K2 MK-7 : 90 mcg
- Vitamin K1 : 1 mg
- Combines a mix of vitamin K2 and K1 with both forms of K2 included
- Great dosage to improve your heart health consistently
- Small capsules size makes it easy for daily vitamin K supplementation
- The vitamin K2 MK-7 dosage could be a good bit higher
5 - InnovixLabs Full Spectrum Vitamin K2
This is one of the simplest vitamin K2 supplement products in that it really only contains the two forms of vitamin K.
My dietitian highlighted that the advantage of this is that it makes stacking with other vitamins for a truly custom stack a lot easier.
Our team tested these for a month, and we didn’t encounter any side effects.
I would just like to see a stronger dose of vitamin K2 MK-7, which studies suggest is more bioavailable [4].
Quick Facts:
- Vitamin K2 MK-4 : 500 mcg
- Vitamin K2 MK-7 : 100 mcg
- Delivers both vitamin K forms as MK-4 and MK-7
- Comes in a large bottle of 90 capsules to keep you going for months
- It’s one of the more affordable natural vitamin supplements
- A larger dose of vitamin K MK-7 would make this a better supplement
6 - NOW Supplements, Vitamin K-2
This is another one of the vitamin K2 supplements that are ideal for people trying to stack it with other vitamins to come up with a tailored stack. I’ve used to take a precise amount of K2, which is a benefit of the lower dose per capsule.
But keep in mind that most people will likely need to take two capsules a day to get an ideal amount of vitamin K.
Quick Facts:
- Vitamin K2 MK-4 : 100 mcg
- Focuses only on delivering vitamin K2, making it easier to stack
- Comes in large bottles of 250 capsules to keep you going for months
- The capsules are conveniently small, making them easy to swallow
- It’s based on vitamin K2 MK-4 with a relatively low dose
7 - USDA Organic Vitamin K2
This is the first vitamin K2 supplement that we found that has a certified organic label.
And that will make it interesting for many dieters who are trying to maximize their organic food intake from all angles.
My dietitian also highlighted that it contains a small amount of MCT oil that has benefits for brain health and energy [5].
“MCTs can delay brain aging by promoting the repair of brain cell damage, especially when combined with a high-fat diet.”
- Patrick Alban, DC at bebrainfit.com
And if you want to take a precise dosage of vitamin K2, then this liquid option will make that a lot easier to achieve.
Quick Facts:
- Vitamin K2 MK-7 : 100 mcg
- Comes in liquid form that allows for easy adjustment to the dosage
- Contains a small amount of MCT oil for added brain power
- Certified organic natural vitamin K supplement
- Some added vitamin D3 would be great of a supplement at this price
8 - NatureBell Vitamin K2
NatureBell is a supplement company that you’ll find in many health food and supplement stores, and this vitamin K2 supplement is designed to give a good dose of the two types of K2.
As a result, you’ll be able to easily add this to your personally tailored stack with a dosage that is close enough to what most dietitians recommend.
I also like that you can order large bottles of it to keep you going for over six months without having to worry about stocking up again.
Quick Facts:
- Vitamin K2 MK-4 : 50 mcg
- Vitamin K2 MK-7 : 150 mcg
- Focuses on delivering only vitamin K2 to make stacking easier
- Comes with a good dose of vitamin K2 MK-7 for faster absorption
- Available in large bottles that will last for over six months
- These are not the smallest capsules to swallow
9 - Life Extension Super K
This Life Extension Vitamin K2 is another good option for people who want to see a combination of both K2 and K1.
With a good dose of both, this can also be the ideal choice if you want to avoid taking multiple capsules of vitamin K every day.
Our team also highlighted during testing that the softgel capsules are easier to swallow than most other harder capsules. They don’t tend to get stuck or feel sore while swallowing.
Quick Facts:
- Vitamin K1 : 1,500 mcg
- Vitamin K2 MK-4 : 1,000 mcg
- Vitamin K2 MK-7 : 100 mcg
- Comes with both vitamin K2 and K1
- Higher dose of MK-4 is great for getting a boost if you’re deficient in vitamin K2
- The softgels are easier to swallow than typical hard capsules
- It’s quite an expensive product, even for the higher dosage
10 - Solgar Vitamin K2
The final one of our best vitamin K2 supplement recommendations comes from one of the leading brands in the vitamin space. Solgar has created this product.
You get a decent dose of Vitamin K2 in each capsule, and it’s the form that has a longer-lasting effect on your health.
And while it is a vitamin K and calcium combination, I think the company could improve by increasing the amount of calcium.
Quick Facts:
- Vitamin K2 MK-7 : 100 mcg
- Calcium : 115 mg
- Includes some calcium to help with bone repair and density
- The capsules are smaller than average, making them easy to swallow
- Provides vitamin K MK-7 for easier absorption and lasting effects
- The amount of calcium is very low, so you’ll need to get a full dose somewhere else
Buyer’s Guide
Here are a few important things to consider before choosing a Vitamin K supplement.
Who Should Take Vitamin K2 Supplements?
Anyone who doesn’t regularly eat fermented food should consider taking vitamin K supplements.
There is also scientific evidence that people can reduce liver cancer recurrence with a regular K2 intake [6].
And if you want to prevent natural bone deterioration and cardiac issues, then this is also a great way to take simple steps with big results.
“Vitamin K2 appears to protect the bones more than Vitamin K1, but too little of either is bad for the bones. Studies have shown that poor Vitamin K intake is linked to low bone mass, osteoporosis and fracture risk.”
- Mark Richens, Writer at americanbonehealth.org
Dosage
When it comes to the dosage, you need to pay attention to each form of vitamin K2, i.e., MK-4 and MK-7. For people with significant vitamin K deficiency, it’s best to aim for 100 mcg of MK-7 and over MK-4.
Some people say you should avoid taking too much K2 due to blood clotting risks. However, it’s important to note that it doesn’t cause blood clotting but is rather an important factor in allowing the clotting process to happen when needed [7].

Form Of Vitamin K2
There are two types of K2, and dietitians generally advise getting MK-7 as it’s the most bioavailable form of vitamin K. It also plays a key role in calcium metabolism, and the majority of supplements we tested focused on this form [8].
Like other fat-soluble vitamins, it’s best not to take on an empty stomach and rather take it with some fat-rich foods like dairy products.
FAQs
What Kind Of Vitamin K2 Is Best?
Vitamin K2 MK-7 tends to be better because it’s classed as being more bioavailable. That means you need less of it in a vitamin K2 supplement, and you’ll find it in fermented foods.
Is It Good To Take Vitamin K2 Every Day?
Yes, it’s good to take vitamin K supplements every day. This vitamin plays a critical role in delivering calcium to bones by helping enzymes convert matrix GLA protein and inhibit calcification in arteries.

Out of the products we tested for this best vitamin k2 supplements list, the one that our dietitian highlighted and most of our testing team liked the most is Live Conscious K2+D3.
It contains the MK-7 form of vitamin K, which is the generally preferred option and also delivers a good dose of vitamin D3. That can set up for improved immunity, as well as bone density, as they work together in vital body repair processes.
