Vitamin D3 + K2 - synergy of action for bone health
Supplements containing a combination of vitamin D3 and K2 are an extremely effective way to maintain bone health. In addition, they have a beneficial effect on the condition of bones, teeth and muscles and ensure proper bone growth and development, so they are also recommended for the youngest children.
Vitamin D3 enables calcium to be absorbed from the gastrointestinal tract into the blood, while vitamin K2 ensures that calcium gets into the bone tissues, which is exactly where it is needed. This also prevents the build-up of calcium in the blood vessels, which can result in the onset of diseases such as atherosclerosis or stroke.
Vitamin D3 + K2 supplements are most often available as capsules, tablets and drops. However, in order for their combination to be effective, it is important to remember the correct daily doses.
For vitamin D3, the appropriate amount is as follows:
Infants up to 6 months of age - 400 IU/day (10 µg/day), regardless of feeding regime. Infants 6-12 months of age - 400-600 IU/day (10 -15 µg/day), regardless of feeding regime.
Children 1-10 years - 600-1000 IU/day (15-25 µg/day).
Adolescents 11-18 years - 800-2000 IU/day (20-50 µg/day).
Adults 18-65 years - 1000-2000 IU/day (25-50 µg/day).
Seniors (over 65 years of age) - 2000-4000 IU/day (50- 100 µg/day).
It is best to consult a doctor and have a blood test to determine vitamin D3 requirements before starting supplementation. Its daily doses depend on the time spent in the sun, complexion, age, health status and body weight.
For vitamin K, doses are not strictly defined and vary from country to country. According to the European Food Safety Authority, the adequate intake of vitamin K is 1 μg /kg body weight for adults, children and pregnant women. Vitamin K doses for children are assumed to be about 10-30 µg/day and for adults about 90-120 µg/day.

Vitamin D3 + K2 - effects
The combination of vitamins D3 + K2 in one preparation primarily has a positive effect on the skeletal, immune and circulatory systems. The synergy of these vitamins helps to increase the absorption of calcium, which prevents its accumulation in the walls of blood vessels. In turn, reducing tissue calcification reduces the risk of coronary heart disease, among other things.
The combination of vitamin D and K also strengthens immunity, helps to improve cognitive function and regulates the absorption of calcium and phosphorus. Vitamin D3 + K2 supplementation is recommended for both healthy people and those struggling with chronic diseases.
