The Science Behind Vitamin D3 and K2


Vitamin D3

Vitamin D is both a nutrient we eat and a hormone our bodies make. It is a fat-soluble vitamin that has long been known to help the body absorb and retain calcium and phosphorus; both are critical for building bone. 

Also, laboratory studies show that vitamin D can reduce cancer cell growth, help control infections and reduce inflammation. 

Many of the body’s organs and tissues have receptors for vitamin D, which suggest important roles beyond bone health, and scientists are actively investigating other possible functions.

Vitamin K2 (Menaquiones 7)

Vitamin K is a fat-soluble vitamin that comes in two forms. The main type is called phylloquinone, found in green leafy vegetables like collard greens, kale, and spinach. The other type, menaquinones, are found in some animal foods and fermented foods. Menaquinones can also be produced by bacteria in the human body.

Vitamin D has a dependent relationship with vitamin K2, and vitamin D toxicity can actually be caused by a deficiency in vitamin K2. The benefits of vitamin D3 are greatly enhanced by the presence of vitamin K2 in terms of bone strength, cardiovascular health, and more.

Key Benefits Vitamin D3

Advantages of taking fungal derived digestive enzymes



Several studies link low vitamin D blood levels with an increased risk of fractures in older adults, and they suggest that vitamin D supplementation may prevent such fractures—as long as it is taken in a high enough dose. Vitamin D may also help increase muscle strength, which in turn helps to prevent falls, a common problem that leads to substantial disability and death in older people. A combined analysis of multiple studies found that taking 700 to 1,000 IU of vitamin D per day lowered the risk of falls by 19%.



The heart is a large muscle, and like skeletal muscle, it has receptors for vitamin D. Immune and inflammatory cells that play a role in cardiovascular disease conditions like atherosclerosis are regulated by vitamin D. The vitamin also helps to keep arteries flexible and relaxed, which in turn helps to control high blood pressure.

Frequently Asked Questions

Are Vitamin D supplements effective?

In a separate clinical trial comparing a 10-week regimen of twice weekly 50,000 IU dosing of both vitamin D2 and vitamin D3 in demographically matched groups, vitamin D3 was also found to be superior in producing higher levels of 25D, or calcifediol. Calcifediol is commonly referred to as the active form of vitamin D.

 Can Vitamin D cause constipation?

Taking vitamin D can increase levels of calcium in the blood, and too much calcium can cause side effects. If you take large doses of vitamin D, you may experience stomach pain, loss of appetite, constipation, or diarrhea as a result of elevated calcium levels.

Are Vitamin D supplements safe?

Vitamin D supplements are considered very safe, and toxicity is uncommon. This is because a healthy person would need to take extremely large doses of vitamin D over time in order to reach toxic or dangerous levels in the body.

Will Vitamin D help me with a cold or flu?

Investigators found that daily or weekly supplementation had the greatest benefit for individuals with the most significant vitamin D deficiency (blood levels below 10 mg/dl) — cutting their risk of respiratory infection in half.

Will Vitamin D affect my sleep?

Vitamin D deficiency may negatively impact sleep quality. Some anecdotal reports assert that supplementing with vitamin D at nighttime may interfere with sleep, but scientific data to that effect is unavailable. Vitamin D is best taking in the morning or mid day. 

Why is K2 paired with Vitamin D?

Vitamin K2 promotes bone and heart health by activating two proteins which balance calcium in the body. K2 activates the osteocalcin proteins that incorporate calcium to bones. Meanwhile, vitamin D3 aids calcium absorption into the blood and has been linked to a reduced risk of breast cancer.
