Vitamins D3 and K2: Better Together

Vitamin D deficiency is immensely common in society, with a 2020 review reporting that 24% of Americans and 40% of Europeans are deficient in vitamin D. This can be dangerous because of the many functions vitamin D assists in.*

The Role of Vitamin D3

Vitamin D plays a role in:

•Bone metabolism
•Wound healing
•Insulin and glucose balance
•Blood pressure regulation
•Muscle health
•Skin health
•Immune system regulation
•Immune response
•Cognitive decline

Vitamin D is commonly viewed as something we need for bone health, and while that is true, it is clear that it plays a much more universal role in our bodies than many of us are aware of. However, this makes vitamin D deficiency all the more dangerous.* 

There are two primary ways of getting vitamin D, ingestion (through food or supplements) and absorption (from the sun). Vitamin D is the only vitamin you can get just from spending time in the sun, and this is because the skin contains vitamin D receptor cells that can manufacture its own vitamin D when exposed to the sun.*

Vitamin D2 vs. Vitamin D3

There are two types of vitamin D – vitamin D2 and vitamin D3. Both can be consumed through food or supplements, and vitamin D3 can also be created when the skin of the body is exposed to ultraviolet B rays from the sun. While both vitamin D2 and D3 can help you meet your daily vitamin D requirements, research suggests that vitamin D3 is more effective than vitamin D2 at raising the levels of vitamin D in the blood.*

The Role of Vitamin K2

Compared to the more popular vitamins, such as vitamin C or vitamin D, vitamin K is much less well-known, leaving many to undermine its importance. However, some research suggests that vitamin K deficiencies may be the link between diet and certain chronic diseases. Unfortunately, vitamin K is very rare in the Western diet, making its supplementation all the more important.* 

Similar to vitamin D, vitamin K comes in two forms: vitamin K1 and vitamin K2. It also plays an important role in the body by activating proteins that assist in blood clotting, heart health, and calcium metabolism.* 

Controlled studies have allowed researchers to observe that, while vitamin K2 supplements improve bone and heart health, there are no significant observable benefits from vitamin K1 supplements.* 

While vitamin K, on its own, assists in essential bodily functions, it also has some important roles that can only be done with vitamin D.*

Try Qummune™

Separately, vitamin D3 and vitamin K2 offer many benefits to the body. Vitamin D3 promotes bone strength, immune support, and cardiovascular health; Vitamin K2 helps with wound healing and blood clotting.*
Vitamin D is an essential vitamin to supplement, but to get the greatest benefit, it is recommended to combine its supplementation with vitamin K. This is because vitamin K helps ensure that vitamin D properly transports calcium to the bones, promoting bone and cardiovascular health.*

When taken together, vitamin D3 and K2 boost the effects of each other, which is why our supplement Qummune™ contains both vitamins in addition to quercetin and many other beneficial compounds. These supplement-packed pills are perfect for those with pill fatigue because they make it easier than ever for you to reap the benefits of vitamin D and K within a single pill.*
