Vitamin K and D are essential nutrients for bone and cardiovascular health [*]. 

Vitamin K plays an important role in calcium absorption. It ensures that calcium is deposited on bones instead of the arteries where it can be dangerous. Vitamin K exists in two forms: K1 from leafy green vegetables, and K2 from fermented dairy.  [*]

There are also different types of Vitamin D. Vitamin D2 comes from mushrooms, and human skin produces Vitamin D3 when it is exposed to sunlight. Fatty fish are also a good source of Vitamin D3.  Vitamin D plays a key role in calcium and phosphorus absorption [*].

Vitamin D deficiency has been observed to weaken bones, cause bone deformities in children, and increase risk of fall and bone fracture among the elderly [*]. 

Vitamin K and D are essential for bone and cardiovascular health. To ensure you are getting these nutrients, incorporate a variety of leafy greens, fermented dairy, and fatty fish in your diet [**]. 

There are also a wide variety of Vitamin K2 and D3 supplements available in the market.

Things To Be Cautious About

Has your brand been third-party tested? You should never buy supplements that don’t have Certificate of Analysis. The studies should be conducted in labs that are not affiliated with the manufacturer. These labs verify the product for safety and potency.

Does your k2 d3 supplement contain cheap synthetic fillers? Some brands add artificial fillers to cut cost to offer cheap products. Some of these cheap fillers we found were titanium dioxide and artificial coloring. You should never purchase cheap products when it comes to supplements.

No return policy or customer service – A reputable supplement company will offer 100% money-back guarantee policy and provide customer support through phone number and email. We noticed many formulas out there are just copies of the top-rated brands. They don’t offer an easy refund policy or don’t even have a phone number to prove they are real.
