A daily serving of as many as 3 tablets places only 750 IU (18.75 μg) of vitamin D3 and 48.75 μg of vitamin K2. Also, the doses of zinc and calcium do not cover the daily recommended intake. Use of the supplement is intended to improve bone, muscle and dental health, strengthen immunity, support the cardiovascular system and maintain normal connective tissues.

Vitamin D3+K2 supplements - synergistic action for bone health
Supplements containing a combination of vitamins D3 and K2 are increasingly popular, especially in the context of preventing osteoporosis and supporting bone health. Their synergistic effect is that vitamin D3 increases the absorption of calcium from the gastrointestinal tract, while vitamin K2 is responsible for its proper utilization, as it activates proteins that transport calcium to the bones and teeth, while preventing its accumulation in the arteries. Thanks to this combination, calcium not only goes where it is needed, but also does not endanger the cardiovascular system. Regular use of vitamin D3+K2 supplements maintains strong bones, reduces the risk of fractures and supports the body's overall calcium-phosphate balance. It is an extremely effective way that works comprehensively and multilevelly - supporting both the structure of the skeleton and the health of the entire body.
How to choose the best vitamin D3+K2 supplement?
In creating our ranking of the best supplements with vitamin D3+K2, we took into account the following criteria:
What doses of vitamins D and K does the supplement contain?
Is it effective in improving bone health?
Is the composition of the supplement simple?
Are there any unnecessary substances in it that may be harmful to health?
Is there oil in the composition of the supplement?
Is the supplement easy to use?
Does it cause no adverse reactions?
Is the packaging efficient?
Is the price of the supplement commensurate with the quality and effectiveness?
What are the appropriate daily doses of vitamins D and K?
Doses of vitamin D are most often given in IU (International Unit), the international unit used to indicate the amount of biologically active substances, such as vitamins or hormones. In the case of vitamin D, the IU indicates its biological activity, not its weight. For example:
- 400 IU = 10 µg (mcg - microgram)
- 1000 IU = 25 µg
- 2000 IU = 50 µg
- 4000 IU = 100 µg
IU makes it easier to compare dosages of preparations, regardless of the chemical form of vitamin D.
Vitamin D dosage for different age groups:
- Infants up to 6 months of age: 400 IU/day (10 µg/day), regardless of feeding method.
- Infants 6-12 months: 400-600 IU/day (10-15 µg/day), regardless of feeding regimen.
- Children 1-10 years: 600-1000 IU/day (15-25 µg/day).
- Young people 11-18 years: 800-2000 IU/day (20-50 µg/day).
- Adults 18-65 years: 1000-2000 IU/day (25-50 µg/day).
- Seniors (age 65+): 2000-4000 IU/day (50-100 µg/day).
Preferably, before starting supplementation, consult a doctor and take a blood test to determine the need for vitamin D3. Its daily dosage depends on time spent in the sun, complexion, age, health and body weight.
Dosage of vitamin K:
For vitamin K, dosages are not strictly defined and vary from country to country. According to the European Food Safety Authority, the appropriate intake of vitamin K is 1 μg/kg body weight for adults, children and pregnant women. Doses of vitamin K for children are assumed to be about 10-60 µg/day, and for adults about 90-120 µg/day.
What is vitamin D3?
Vitamin D3 (cholecalciferol) is one of the two main forms of vitamin D - along with vitamin D2 (ergocalciferol). Vitamin D3 is naturally synthesized in our skin when exposed to UVB radiation. It is also found in some animal products, such as fatty fish, egg yolks and liver. However, it is virtually impossible to make up for deficiencies of this vitamin with diet alone, and therefore it should be supplemented especially during the fall and winter.
The main effects of vitamin D3 are:
- Promoting bone and dental health - its deficiency can lead to rickets in children and osteoporosis in adults.
- Strengthening the immune system.
- Influencing the nervous and muscular systems.
- Improve mental health.
What is vitamin K2?
Vitamin K2 (menaquinone) is a fat-soluble vitamin, one of the two main forms of vitamin K - along with vitamin K1 (phylloquinone). Vitamin K2 is mainly found in animal products and fermented foods. It is also produced in small amounts by intestinal bacteria. Vitamin K2 plays a key role in processes related to blood clotting, bone health and the cardiovascular system.
Main actions of vitamin K2 include:
- Promoting proper blood clotting.
- Promoting bone health.
- Promoting bone health. Participate in the activation of calcium-binding proteins in bones.
- Promote bone mineralization and density.
- Promote bone health. Protection of the cardiovascular system.
Vitamin D3+K2 - action
Vitamin D3 and K2 are often supplemented together because their actions in the body are closely related and complementary. Vitamin D3 is responsible for increasing the absorption of calcium from the gastrointestinal tract into the blood. However, increasing calcium levels alone may not be enough for bone health, because instead of going to the bones, it can be deposited in soft tissues like blood vessels. And that's when vitamin K2 comes to the rescue. Vitamin K2 activates two important proteins: osteocalcin and MGP (Matrix Gla Protein). The former directs calcium to the bones and teeth, promoting their mineralization and strengthening their structure. The second prevents calcium deposition in the arteries, which could lead to atherosclerosis or other cardiovascular diseases. In short, vitamin D3 provides calcium, and vitamin K2 helps to utilize it properly. This is why these two vitamins are often found together in supplements, and it is recommended to take them at the same time, especially for long-term supplementation with higher doses of vitamin D3.
What is the best vitamin D3+K2 supplement?
The best vitamin D3+K2 supplement should contain natural vitamin D3 (cholecalciferol) and vitamin K2 in the MK-7 form, as this is the most stable and best absorbed form of K2. The supplement should have a simple formulation and contain oil, as both vitamins are fat-soluble and the presence of oil significantly increases their absorption. In addition, the formula should be convenient to use, efficient and inexpensive.
How to use vitamin D3+K2 supplements?
Vitamin D3+K2 supplements are best taken once a day, with a meal containing fat, as both vitamins are fat-soluble and are then best absorbed. Dosage should be adjusted according to individual needs, age, weight, season and blood vitamin D levels. For example, in the fall and winter, doses of 2000-4000 IU of vitamin D3 per day, combined with about 75-100 µg of vitamin K2, are often recommended. For those taking anticoagulants or having chronic diseases, supplementation should be consulted with a doctor.
What are the benefits of vitamin D3+K2 supplements?
The most important benefits of taking vitamin D3+K2 supplements include:
- Strengthening bones and teeth.
- Protection of the cardiovascular system.
- Immune support.
- Promoting nerve and muscle function.
- Faster utilization of calcium from diet or supplements.
- Reducing the risk of osteoporosis and fractures.
