Should You Take Vitamin D3 and K2 Together?
Supplementing with vitamins D3 and K2 may synergistically support cardiovascular and bone health by improving calcium metabolism and preventing vascular calcification.
Taking vitamin D3 and K2 together is generally recommended, as these two fat-soluble vitamins work synergistically to support bone health and prevent conditions like osteoporosis. Vitamin D3 helps your body absorb calcium from your diet, ensuring sufficient amounts of this essential mineral are available in the bloodstream.
However, without vitamin K2, the calcium absorbed by D3 may not be directed appropriately, potentially leading to calcification in soft tissues, such as the arteries. K2 is critical in ensuring that calcium is deposited in the bones where it is needed rather than in the arteries. This helps promote strong bones while preventing calcium buildup in unwanted areas.
Additionally, the combination of D3 and K2 is beneficial for cardiovascular health. Vitamin K2 inhibits arterial calcification and arterial stiffening by activating matrix GLA protein (MGP), a key inhibitor of calcium deposits on the artery walls. Adequate K2 intake can, therefore, lower the risk of vascular damage, promoting better arterial health.
This combination also has additional benefits for individuals with type 2 diabetes, as studies suggest that D3 and K2 together can improve insulin action in overweight patients, helping manage blood sugar levels and reduce associated health risks.
How to Choose Vitamin D3 and K2 Supplements - Buying Guide
Check the Dosage: A Balanced Supplement Should Offer a D3 to K2 Ratio of Around 1,000:10
The recommended daily dosage of vitamin D3 and K2 supplements can vary based on individual needs.
According to Poland's 2023 vitamin D guidelines, general recommendations from this report now suggest taking 1,000-2,000 IU of vitamin D3 daily.
For vitamin K, the National Institutes of Health (NIH) recommends that men consume 120 mcg of vitamin K daily, while women need 90 mcg.
There is no strict ratio for D3 to K2 intake, as individual vitamin D requirements differ. However, common suggestions are to take 10 mcg of K2 for every 1,000 IU of D3 (or 50 mcg of K2 for every 5,000 IU of D3). This ratio helps support calcium balance and cardiovascular health.
Vascular calcification (VC), common in end-stage kidney disease and linked to K2 depletion, was reduced by 360 mcg of K2 daily in over 61% of dialysis patients, while postmenopausal women showed arterial stiffness improvement with just 180 mcg.
The results of these studies indicate that outcomes are responsive to varying dosages of vitamin K2, which may differ based on the medical condition of the population being treated.
Select the Form of K2 with the Benefits You Seek
Choose MK-7 (Menaquinone-7) for the Most Bioavailable and Effective Form of K2
MK-7 is the most bioavailable and longest-lasting form of K2, meaning it stays in the bloodstream longer, allowing for more effective calcium regulation. This form is particularly beneficial for older adults or postmenopausal women at a higher risk of bone density loss or osteoporosis. MK-7 helps direct calcium to the bones and away from arteries, reducing the likelihood of calcium deposits in arteries that can lead to cardiovascular issues.
MK-7 is also ideal for those seeking long-term health benefits with less frequent dosing. Since it remains active in the body longer than the MK-4 form, individuals can maintain consistent levels of K2 with a once-daily supplement.
Individuals concerned about heart health, especially those with a family history of heart disease or arterial calcification, should opt for MK-7 to ensure their calcium is properly utilized and does not contribute to arterial plaque buildup.
There are two forms of MK-7, cis and trans, and the label should differentiate which form is being used. You should opt for the trans form of this supplement. The cis form is cheaper, but the trans form entirely determines therapeutic effectiveness.
Pick MK-4 (Menaquinone-4) if You're Seeking Short-Term, High Dose Benefits
MK-4 is particularly beneficial for lowering LDL (bad cholesterol), which helps reduce plaque buildup in the arteries and lowers the risk of cardiovascular diseases.
MK-4 can decrease atherogenesis by reducing low-density lipoproteins or LDL (bad cholesterol), which decreases the risk of plaque buildup in the arteries. This helps prevent the development of cardiovascular disease by promoting better lipid regulation and artery health.
MK-4 is particularly suitable for those who already take frequent doses of other supplements or medications and prefer flexibility in adjusting the dosage of K2 throughout the day. Since MK-4 clears the body more quickly, some may prefer to take it multiple times a day for a more controlled, consistent intake.
Additionally, research has shown that MK-4 plays a role in bone health and has been used in higher doses of 45 mg to treat osteoporosis, which may benefit individuals under medical supervision needing specific bone support.
Look for Products with MCT (Medium-Chain Triglyceride) Oil to Enhance Absorption
People with digestive sensitivities or conditions impairing fat absorption, such as celiac disease or gallbladder issues, can also benefit from MCT oil supplements. The liver easily digests and directly absorbs MCTs, making them ideal carriers for vitamins D3 and K2.
Consider Formulations with Magnesium to Support Cardiovascular, Heart, and Bone Health
Magnesium supports bone health and regulates heart rhythm, blood pressure, and overall cardiovascular function. When combined with D3 and K2, magnesium enhances the effectiveness of these vitamins by ensuring proper calcium metabolism.
For Cardiovascular Health: Magnesium helps prevent calcium from building up in the arteries, a risk factor for heart disease. This combination is particularly beneficial for those focused on maintaining heart health and preventing arterial calcification.
For Bone Health: Magnesium is essential for activating vitamin D3 and improving bone calcium absorption. Vitamin D3 may not function effectively without adequate magnesium, and calcium may deposit in soft tissues rather than being directed to the bones. Adding magnesium to the formula is helpful for older adults or those at risk of osteoporosis, as it ensures calcium is utilized correctly and contributes to bone health rather than causing harm to arteries or tissues.
Choose the Form of Supplement That Suits Your Condition
Opt for an Oil-Based Capsule or Softgel for Better Absorption
Oil-based capsules improve the bioavailability of fat-soluble vitamins such as D and K by enhancing their digestion and absorption through the lymphatic or hepatic systems.
Since both D3 and K2 are fat-soluble, they must be taken with fat for optimal absorption. Oil-based softgels provide this essential fat within the capsule itself, ensuring that the vitamins are absorbed efficiently, even if the supplement is taken on an empty stomach or with a low-fat meal. This form is ideal for individuals with poor fat intake or those seeking a more reliable, convenient absorption method.
Softgels are often smaller and smoother compared to tablets, making them easier to take, especially for older adults or those who struggle with swallowing pills.
Softgels provide a pre-measured dose of both vitamins, offering consistency and accuracy in supplementation, which is beneficial for people managing specific health concerns like bone density or cardiovascular health.
Go for a Liquid Form if You Prefer Flexible Dosing or Have Difficulty Swallowing Pills
Liquid supplements allow for easy dosage adjustment to tailor your intake to your specific healthcare needs. This is especially useful for children, older adults, or those needing to increase or decrease their dosage gradually.
Liquids are generally absorbed more rapidly by the body than capsules or tablets, allowing for quicker utilization of the vitamins. This makes liquid vitamin D3 and K2 ideal for individuals who need immediate health support, such as those with severe vitamin deficiencies or people managing acute health conditions related to bone density or cardiovascular health.
Drops or liquid supplements are often free of unnecessary fillers, providing a purer option for health-conscious consumers. Their liquid form also makes them excellent for individuals with swallowing difficulties who prefer to ingest supplements mixed in food, drinks, or smoothies.
Check for Products That Have Been Third-Party Tested for Purity, Potency, and Safety
Consumers should actively look for a Certificate of Analysis (COA) for each product, demonstrating that it has been rigorously tested for quality and purity.
A certification seal from reputable organizations such as NSF, USP, GMP, or ConsumerLab.com indicates that the product has met specific standards for safety and efficacy. These certifications serve as a reliable benchmark for consumers, helping them select high-quality supplements that are both effective and safe for consumption.

Potential Side Effects of Vitamin D3 and K2
When taken in recommended doses, the combination of vitamin D3 and K2 is generally considered safe. However, taking excessive amounts of D3 can lead to hypercalcemia, where too much calcium accumulates in the blood. This hypervitaminosis can result in symptoms like nausea, vomiting, fatigue, and kidney stones. While K2 helps direct calcium to the bones and away from arteries and has hypervitaminosis protective effects for D3, over-supplementation with D3 can still pose risks, especially if taken in extremely high doses without medical supervision over a prolonged period.
Individuals on blood-thinning medications, like warfarin, need to be cautious with vitamin K2, as it can interfere with the medication's effectiveness by promoting blood clotting. Additional medications that may be affected include anti-seizure drugs, antibiotics, fat-blockers, and others. It's crucial to follow dosage guidelines and consult with a healthcare provider, especially for those with pre-existing conditions or taking any medication.
