Vitamin K2 and D3 haven’t always been seen as the best of buds, but recent studies have been indicating many benefits from the combination of the two. It seems that both of these vitamins are fat-soluble and both aid in the support of cardiovascular and bone health. Separately they have their benefits, but together, they make a considerable difference to how your body absorbs and works within itself.
Let us explain…
When it comes to healthy bones, it is not just a matter of taking in a bunch of calcium and calling it a day. Well, you can still take in that calcium, but there is a little more to this equation. When we have too much calcium in our bodies, it comes out as a negative. It can make our bones weak, calcium can build up in our arteries and arterial system, turn into kidney stones, cause calcified tendinitis or create bone spurs. While it may seem confusing as to why this is happening, the straightforward answer is that you are deficient in vitamin K2. A vital part of calcium metabolism to our bones.
On top of this, vitamin D3 doesn’t only aid in calcium absorption, but calcium is very much dependent on vitamin D for proper absorption, specifically in the intestines. A sufficient amount of D3 is able to pull the calcium into the bloodstream.
However, with only D3 in our systems, there would be too much calcium in our bodies, which is why K2 is just as important and why they make such an excellent pair. When taking vitamin K2D3 together, the K2 can take the excess calcium and place them in our skeletal system where it belongs.
To bring it back around and keep it simple. We consume calcium for healthier bones, the D3 we consume will aid in calcium absorption in the intestines and the K2 we consume will take calcium and distribute it into our bones. At the end of the day, we need both and need them together.
NCBI Narrative Review 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.”
Individually, what are the benefits of Vitamin K2 and Vitamin D3?
The benefits of vitamin K2 are vital for optimal bone health. Even being dubbed the most powerful obstacle for vascular calcification which is “mineral deposits on the walls of your arteries and veins. These mineral deposits sometimes stick to fatty deposits, or plaques, that are already built up on the walls of a blood vessel” according to UPMC. K2 is able to remove the plaque in soft tissues and keep your arteries elastic which we lose with age.
Studies with vitamin K2:
- Due to the reduction of calcium being deposited into arteries, the risk of heart disease can be decreased. Openheart states “Increased vitamin K2 intake may reduce arterial stiffness, slow progression of vascular and valvular calcification, lower the incidence of diabetes and coronary artery disease, and decrease cardiovascular mortality.”Cardiovascular mortality being any disease that affects the heart or blood vessels.
- Despite most of the benefits being based around bones, two clinical studies have suggested K2 could also be a fighter against cancer. Healthline states, “vitamin K2 reduces recurrence of liver cancer and increases survival times. Additionally, an observational study in 11,000 men found that a high vitamin K2 intake was linked to a 63% lower risk of advanced prostate cancer, whereas vitamin K1 had no effect.”While more studies need to take place, it is a great starting point.
Vitamin D overall plays a fairly large role in our bodies. Not merely concerning stronger bones and teeth, but also our immune system, cardiovascular health, mood, skin and even depression. It is not only a very effective vitamin but as a prohormone that our body can produce, positively affects many different parts and aspects of our body.
Studies with vitamin D3:
Along with supplementing D3 with a healthy diet, diabetes.co.uk states “Vitamin D is believed to help improve the body’s sensitivity to insulin – the hormone responsible for regulating blood sugar levels – and thus reduce the risk of insulin resistance, which is often a precursor to type 2 diabetes.”
One of the major benefits of vitamin D3 remains its ability to strengthen your immune system. This means being able to fight colds and cases of the flu. Benessere Clinic states “An analysis of multiple studies evolving vitamin D and respiratory infection demonstrated vitamin D supplementation was safe and protected against respiratory infection, especially in individuals who were the most vitamin D deficient.”
It’s not very clear as to why vitamin D is linked with our mood. The fact that something like seasonal depression could be improved by our intake of vitamin D is quite interesting. The concept is we either have depression because of low vitamin D, or being inside more with less water and healthy food can cause low vitamin D. Either way, Frontiers in Neuroscience states “it has been postulated that vitamin D is involved in the serotoninergic system, influencing serotonin metabolism and contributing to circadian rhythm maintenance, which are important aspects of the development of depressive symptoms.”
While there is plenty of more research to be conducted on the potentially more benefits of vitamin k2d3 together, it is important to understand that it is more than vital to consume these as a pair. For calcium absorption and all the benefits these vitamins have on their own, there is no better time than now to start your daily dose of our amazing 2 in 1 Support Vitamin K2+D3 supplement. With 100mcg of Vitamin K2 and 125mcg/5,000IU of Vitamin D3, you can begin to work on strengthening bones, cardiovascular health and a host of other body supporting benefits!
