Vitamin D3 and K2: Together

The Wonderful World of Vitamin D3 and K2: Together...

Written By: Kristina Innemee

Some combinations are just made for each other, like peanut butter and jelly or Ross and Rachel. When we think about vitamin K2 and vitamin D3, also known as vitamin K2D3, we should in fact be thinking about them as better off in a pair than individually. 


While supplementing vitamins, especially in a world where we lack necessary dietary needs, it isn’t always as straightforward as taking one pill at a time, despite the individual benefits. Some vitamins, as well as foods, do better in our bodies when they are combined. Hence where K2D3’s important combination comes from.


What Is Vitamin K2?


Vitamin K2

There are two components in vitamin K. We have vitamin K1 to help in forming of healthy blood clotting, which is found in vegetables, leafy greens and of course plant oils. We have vitamin K2 to stop the buildup of calcium in our tissue. When we think of this vitamin we need to be thinking of animal products, dairy and fermented foods. Our bodies do produce only a limited amount of vitamin K in the colon.

Our diet very much depends on whether or not we will be deficient. A K2 deficiency could be considered dangerous and should be monitored or supplemented.


Vitamin D3

Although we call D3 a vitamin, it technically isn't a vitamin and scientifically goes by a unique name. According to Medical News Today, we call it a “prohormone, or precursor of a hormone.”Why? Because vitamins are typically not produced in the body or only produce a minuscule amount. Vitamin D, on the other hand, can be produced in our bodies. Even so, that doesn’t mean as a society we aren’t incredible deficient. Which PubMed states we are 41% deficient as a country (135 million people).

Foods like fatty fish, dairy products, mushrooms, egg yolks and fortified food contain smaller amounts vitamin D, but we gain most of ours from the sun. Therefore, no sun means not a whole lot of D and a deficiency can equally cause a few health issues. 


Should K2 Be Taken With D3?


The short answer is yes.


As stated above, studies have indicated the benefits of taking these two vitamins together, especially on cardiovascular health and bone health. An NCBI also states, “taken together, animal and human studies suggest that optimal concentrations of both vitamin D and vitamin K are beneficial for bone and cardiovascular health as supported by genetic, molecular, cellular, and some human studies.”


Check out our in-depth look at taking vitamin K2 and D3 together here. 


The benefits of Vitamin K2 and D3

Separately, Vitamin D and K host a heap of benefits.


Vitamin K2 benefits include:

- “Several studies have reported more health benefits with vitamin K2 than with vitamin K1. It contributes to skin health and bone metabolism, promotes proper brain function and prevents heart-related diseases. Furthermore, vitamin K2 is important in the body’s use of calcium to help build bones and to inhibit blood vessel calcification.” – News Medical Life Sciences

- “Data indicated that vitamin K2 had a positive impact on osteoporosis, cardiovascular disease, parathyroid disorders, cerebral palsy and sperm motility.” – NCBI

- “Interestingly, several studies have been done on vitamin K2 and certain types of cancer.”– Healthline


Vitamin D3 benefits include:

- “Vitamin D plays a significant role in the regulation of calcium and maintenance of phosphorus levels in the blood. These factors are vital for maintaining healthy bones.” – Medical News Today

- “helping to reduce your likelihood of developing the flu, according to 2010 research published in the American Journal of Clinical Nutrition.” – Healthline

- “Vitamin D may help your immune system fight off some illnesses, including COVID-19. It may also help alleviate depression symptoms.” – Very Well Health

Together, vitamin K2D3 are the perfect pair for our calcium absorption. Read our in depth discussion of the vitamin K2D3 combination here


K2D3 Side effects

In most cases, the main side effects you could develop are allergic reactions to the products which can include:

- Rash

- Itching or swelling

- Trouble breathing

- Severe dizziness.

- Nausea or vomiting

- Constipation or an upset stomach


However, this type of reaction is very to each their own as it depends on how your body will handle each vitamin. 


On the other hand, many side effects to vitamin K2D3 come separately. Being deficient in either one can cause some issues in our calcium absorption. Read more on our in-depth discussion on what the side effects of being deficient are can do and how consuming vitamin K2D3 can aid in many ailments. 


*If you are experiencing any sort of side effects, discontinue the use of the product and seek help from your family doctor.


K2D3 Supplement


Consuming supplements ensures you are receiving enough of the vitamins and minerals you need for a strong and healthy body.


Supplementing vitamin D can be extremely important, especially depending on what part of the world you are in. Those who live in areas where the winter sees gloomy weather, snowy moments and inside days need to consume more vitamin D to maintain necessary levels. However, even during the summer time we sometimes don’t get enough sun or vitamin-rich food sources due to our busy schedules, so supplementing could be vital for you.


When it comes to vitamin K2, we could be observing a similar effect, but our deficiency will be dependent on what food we intake. If we are not utilizing enough dietary sources, we could also be looking at deficiencies. 


Supplementing is a great way to ensure you are getting your daily dose of K2D3!
