Vitamin D helps the body absorb calcium from food, while vitamin K contributes to normal blood clotting and bone-related processes. The formula also includes coconut oil, a source of fat that may help with the absorption of fat-soluble vitamins.
- Vitamin D3: Helps the body absorb calcium and supports normal immune function.
- Vitamin K2 MK-7: Contributes to normal blood clotting and supports bone health.
- Virgin Coconut Oil: Provides a fat source alongside the fat-soluble vitamins.

A serving of 10,000 IU exceeds the usual adult tolerable upper intake level of 4,000 IU per day unless a healthcare professional recommends otherwise. Consult a healthcare professional before use, particularly if you take medication or have an existing medical condition.

Micro Ingredients Vitamin D3 K2 MK-7 provides two important nutrients in a convenient softgel formula.

Vitamin K can interact with warfarin and other vitamin K-sensitive anticoagulants, so consult your healthcare professional if you take these medications.
Vitamin D3 and K2 supplements have become popular among adults looking to support bone health, calcium metabolism, muscle function, and normal immune function. Vitamin D3 helps the body absorb calcium, while vitamin K2 contributes to normal blood clotting and plays a role in maintaining healthy bones. Combining these nutrients in one supplement offers a convenient option for people whose diets or vitamin levels may not meet their individual needs.
The best vitamin D3 and K2 supplements vary in dosage, ingredient quality, dietary suitability, serving size, and price. Some products provide moderate amounts for daily supplementation, while others contain higher doses intended for people with specific nutritional needs under professional guidance. Popular options include Micro Ingredients, Sports Research, Nutricost, and Nature Made.
In this guide, we compare five vitamin D3 and K2 supplement options, explain their main features, discuss important buying considerations, and answer common questions to help you make an informed choice.
What Are Vitamin D3 and K2 Supplements?
Vitamin D3 and K2 supplements combine two fat-soluble vitamins that perform different but complementary functions in the body.
Vitamin D3, also known as cholecalciferol, helps the body absorb calcium and phosphorus. These minerals are essential for maintaining normal bones and teeth. Vitamin D also supports muscle function and the immune system.
Vitamin K2 belongs to the vitamin K family. It contributes to normal blood clotting and helps activate proteins involved in calcium regulation and bone metabolism.
Many combined supplements include vitamin D3 and vitamin K2 in a single softgel or capsule. Some formulas also contain coconut oil or another oil because vitamins D and K are fat-soluble nutrients.
Although these vitamins work in related biological processes, evidence does not establish that every combined supplement provides superior results compared with taking vitamin D alone. The most appropriate option depends on your diet, nutritional status, health needs, and advice from a qualified healthcare professional.
Best Vitamin D3 and K2 Supplements
The following products offer different formulations and serving strengths. Product details are based on the supplied descriptions, so check the current packaging for updated ingredients, serving sizes, and certifications.
1. Micro Ingredients Vitamin D3 K2 MK-7 10,000 IU
Micro Ingredients Vitamin D3 K2 MK-7 is a high-potency combination supplement containing vitamin D3 and vitamin K2 in the MK-7 form. The supplied product descriptions list versions containing either 180 or 300 softgels, so verify the bottle size before purchasing.
Each serving provides 10,000 IU of vitamin D3 and 200 mcg of vitamin K2 MK-7. The formula includes virgin coconut oil, and the product is described as non-GMO, gluten-free, dairy-free, and soy-free.
Key Features
- Vitamin D3: 10,000 IU per serving
- Vitamin K2: 200 mcg per serving
- Vitamin K2 form: MK-7
- Added ingredient: Virgin coconut oil
- Item form: Softgels
- Dietary claims: Non-GMO and gluten-free
Why Consider This Supplement?
This product may appeal to adults who have been advised to take a higher dose of vitamin D3. Its combination of D3 and K2 in one softgel is convenient, while the coconut oil provides a source of fat alongside the fat-soluble vitamins.
However, 10,000 IU of vitamin D3 is a high dose for routine use. The usual adult tolerable upper intake level is 4,000 IU per day unless a healthcare professional recommends otherwise. Long-term high intake can cause excessive calcium levels and other complications. This product should not be the default choice for everyday supplementation without medical guidance.
2. Sports Research Vegan Vitamin D3 + K2
Sports Research Vegan Vitamin D3 + K2 is designed for adults who prefer a plant-based vitamin supplement. According to the supplied description, each serving contains 2,500 IU of vitamin D3 and 100 mcg of vitamin K2.
Its vitamin D3 comes from lichen rather than the lanolin commonly used in conventional vitamin D3 products. The formula also includes coconut MCT oil and is described as vegan-certified, non-GMO, gluten-free, soy-free, and carrageenan-free.
Key Features
- Vitamin D3: 2,500 IU per serving
- Vitamin K2: 100 mcg per serving
- Vitamin D3 source: Lichen
- Added ingredient: Coconut MCT oil
- Item form: Plantgels or softgels
- Bottle size: 60 softgels
Why Consider This Supplement?
Sports Research may suit adults seeking a vegan-friendly option with a moderate vitamin D3 dose. The lichen-derived ingredient makes it particularly relevant to people following plant-based diets who want to avoid animal-derived vitamin D3.
Its clearly stated dosage also makes it easier to compare with higher-strength products. Nevertheless, 2,500 IU may be more than some people need, so consider your existing intake and individual requirements before starting supplementation.
3. Nutricost Vitamin D3 + K2 5,000 IU
Nutricost Vitamin D3 + K2 combines vitamin D3 with vitamin K2 MK-7 in a softgel format. According to the supplied product information, each serving contains 5,000 IU of vitamin D3 and 100 mcg of vitamin K2.
The bottle contains 120 softgels and is described as non-GMO and gluten-free. The manufacturer also states that the product is made in a GMP-compliant, FDA-registered facility.

- Vitamin K2: 100 mcg per serving
- Vitamin K2 form: MK-7
- Item form: Softgels

Why Consider This Supplement?
Nutricost may appeal to adults looking for a straightforward D3 and K2 formula without numerous additional ingredients. The 120-softgel bottle offers a convenient supply, and the listed nutrient amounts make the formula easy to compare with other products.
The 5,000 IU vitamin D3 dose exceeds the usual adult upper intake level of 4,000 IU per day for unsupervised intake. It may be appropriate in some situations when recommended by a healthcare professional, but it is not automatically a better choice than a lower-dose product.
4. Nature Made Vitamin D3 + K2
Nature Made Vitamin D3 + K2 is a combined vitamin supplement intended to support bone, muscle, and immune health. According to the supplied product description, each serving provides 5,000 IU of vitamin D3 and 100 mcg of vitamin K2.
The product comes in a bottle containing 90 softgels and is described as gluten-free, without artificial flavors or synthetic dyes. The brand also highlights its experience in dietary supplements and claims USP verification for the product; check the current packaging or official listing to confirm the specific verification status.
Key Features
- Vitamin D3: 5,000 IU per serving
- Vitamin K2: 100 mcg per serving
- Item form: Softgels
- Bottle size: 90 softgels
- Dietary information: Gluten-free
- Other claims: No artificial flavors or synthetic dyes
Why Consider This Supplement?
Nature Made may be worth comparing if you prefer a familiar supplement brand and a product with clearly stated nutrient amounts. Its combination of D3 and K2 offers a convenient format for adults whose healthcare professional has recommended these nutrients.
As with other 5,000 IU formulas, consider the vitamin D3 dose carefully. A higher amount is not necessarily more effective or safer for everyday use. People who already take a multivitamin or vitamin D supplement should account for their total daily intake.
5. Micro Ingredients Vitamin D3 K2 MK-7 10,000 IU, 180 Softgels
The 180-softgel version of Micro Ingredients Vitamin D3 K2 MK-7 offers the same advertised high-potency combination as the larger 300-softgel version. The supplied description lists 10,000 IU of vitamin D3 and 200 mcg of vitamin K2 per serving, with virgin coconut oil included in the formula.

Why Consider This Supplement?
This version may be convenient for shoppers who prefer a smaller package than the 300-softgel option. It has the same advertised nutrient amounts, so the main difference between the two versions is package quantity.
Before choosing either version, consider whether you actually need a 10,000 IU vitamin D3 serving. Such a dose should generally be used with professional guidance rather than as a routine wellness supplement.

Benefits of Vitamin D3 and K2
Vitamin D3 and K2 have distinct roles in the body. Supplementation may be useful when dietary intake or vitamin levels are inadequate, but benefits depend on individual needs.
Supports Bone Health
Vitamin D helps the body absorb calcium, which is essential for building and maintaining bones. Vitamin K contributes to the activation of proteins involved in bone metabolism. Getting adequate amounts of both nutrients supports normal bone function, but supplementation does not replace adequate calcium intake, exercise, or medical care for bone conditions.
Helps Maintain Normal Calcium Metabolism
Vitamin D contributes to normal calcium absorption and regulation. Vitamin K-dependent proteins are involved in processes related to calcium and bone tissue. These functions explain why D3 and K2 are frequently combined in dietary supplements.
Supports Normal Immune Function
Vitamin D plays a role in normal immune system function. People with inadequate vitamin D levels may benefit from correcting that deficiency under appropriate guidance. However, taking high doses does not guarantee stronger immunity or prevent infections.
Contributes to Muscle Function
Vitamin D is involved in normal muscle function. Inadequate vitamin D levels can contribute to muscle weakness in some people, and correcting a deficiency may help address related problems. Persistent weakness or pain should be assessed by a healthcare professional rather than treated with supplements alone.
How to Choose the Best Vitamin D3 and K2 Supplement
The best supplement is not necessarily the one with the highest dosage or the greatest number of ingredients. Consider these factors when comparing products.
Check the Vitamin D3 Dosage
Vitamin D3 supplements come in different strengths, including 1,000 IU, 2,000 IU, 2,500 IU, 5,000 IU, and 10,000 IU per serving. The right amount depends on your age, diet, vitamin D status, health conditions, and professional advice.
For most adults, the recommended dietary allowance is 600 IU daily through age 70 and 800 IU daily after age 70. These figures include intake from food and supplements, and individual needs can vary. The usual adult tolerable upper intake level is 4,000 IU daily unless higher intake is medically supervised.
Look at the Vitamin K2 Form
Vitamin K2 is available in different forms, including MK-4 and MK-7. Many combined supplements use MK-7, also called menaquinone-7. Check the label to identify the specific form and amount rather than relying only on broad claims about vitamin K.
People taking warfarin or other vitamin K-sensitive anticoagulants should consult their healthcare professional before starting or changing a vitamin K supplement.
Review Ingredients and Dietary Requirements
Check whether the supplement contains ingredients that suit your dietary preferences. Vegan shoppers may prefer products using lichen-derived vitamin D3. Others may prioritize gluten-free, soy-free, or dairy-free formulas.
Also check for added oils, allergens, unnecessary ingredients, and capsule materials. If you have food allergies, review the full label rather than relying only on the front-of-package claims.
Consider Testing and Quality Information
Look for clear labeling, batch information, and credible quality-testing details. Third-party testing can provide additional information about product identity and purity, but claims should be verified through the manufacturer or testing organization when possible.
Manufacturing in an FDA-registered facility does not mean the FDA has approved the supplement for effectiveness. Dietary supplements are not evaluated in the same way as prescription medicines.
Compare Cost Per Serving
A larger bottle may provide more servings, but it is not always the better value. Compare the price per serving, the amount of each vitamin, and the serving instructions. Avoid choosing a higher-dose supplement solely because it appears to offer more value.
Who May Need Vitamin D3 and K2 Supplements?
Some adults may benefit from vitamin supplementation because of dietary patterns, limited sun exposure, absorption problems, or a confirmed deficiency. However, the need for vitamin D3 and K2 together varies.
People who may want to discuss supplementation with a healthcare professional include:
- Adults with a confirmed vitamin D deficiency
- People with limited dietary sources of vitamin D
- Adults who spend little time outdoors
- Older adults with specific nutritional needs
- People with conditions affecting nutrient absorption
- Individuals whose healthcare professional has recommended supplementation
Vitamin D status can be assessed through a blood test when medically appropriate. Routine vitamin K testing or supplementation is not necessary for everyone. Your healthcare professional can help determine whether a combined product is appropriate.
Safety Considerations Before Taking Vitamin D3 and K2
Vitamin supplements can cause side effects or interact with medicines, particularly when taken in high doses.
Avoid Unsupervised High-Dose Vitamin D3
Excessive vitamin D intake can cause hypercalcemia, meaning too much calcium in the blood. Symptoms can include nausea, vomiting, weakness, excessive thirst, frequent urination, and kidney problems.
Products containing 5,000 IU or 10,000 IU per serving should not automatically be considered suitable for daily use. Follow professional advice and account for vitamin D from all supplements you take.
Check Medication Interactions
Vitamin K can interact with warfarin and other vitamin K-sensitive anticoagulants. Do not start, stop, or change a vitamin K supplement without consulting the healthcare professional managing your medication.
Vitamin D supplements may also require additional caution for people with certain kidney conditions, elevated calcium levels, or other medical issues.
Follow the Product Label
Do not assume that one softgel equals one serving. Some products may define a serving as more than one softgel. Read the label carefully and follow the recommended instructions provided by your healthcare professional.
Final Thoughts:
The best vitamin D3 and K2 supplements combine clear ingredient labeling, an appropriate dosage, reliable quality information, and a formulation that suits your dietary preferences. Micro Ingredients offers high-potency options, Sports Research provides a vegan-friendly formula, and Nutricost and Nature Made offer alternatives with 5,000 IU of vitamin D3 per serving.
When comparing these products, focus on your individual vitamin needs rather than choosing the highest dose. A healthcare professional can help determine whether supplementation is necessary and what amount is appropriate, particularly if you have a deficiency, take medication, or have an existing medical condition.
