Vitamin D3 functions in the body as a hormone – not just as a vitamin.
After its activation in the liver and kidneys, it is converted into calcitriol , a hormone that affects over 2,000 genes in the human body. This means that it regulates the functions of the immune system, nervous system, muscles, heart and bones .

Study published in The American Journal of Clinical Nutrition in 2025
A recent study published in The American Journal of Clinical Nutrition provided compelling evidence that vitamin D supplementation can slow biological aging through telomere protection. The results showed that the group taking vitamin D experienced significantly less telomere shortening compared to the placebo group. It was estimated that vitamin D “prevented the equivalent of nearly three years of aging” at the DNA level.

Why is it important to combine vitamin D3 with vitamin K2?
Vitamin D3 increases the absorption of calcium from the intestines into the blood, while vitamin K2 ensures that this calcium is deposited in the bones and teeth – not in the blood vessels. Their combination thus supports healthy bones while protecting the cardiovascular system from calcification.
Vitamin K2 (especially menaquinone-7) activates the MGP protein (Matrix Gla Protein) , which prevents calcium from being deposited in soft tissues and vascular walls .
Long-term use of high doses of D3 without K2 poses a risk of arterial calcification .

Is a dose of 10,000 IU of D3 safe?
For a healthy adult, taking 10,000 IU is safe, especially if vitamin D deficiency is detected or during the winter months. It is important to regularly check the level of 25(OH)D in the blood and, after stabilization, adjust the dose according to the doctor's recommendation. According to several studies and data from the World Health Organization (WHO) and the European Union, 40–80% of the population in Europe suffers from vitamin D deficiency
A study published in Dermato-Endocrinology evaluated the safety of administering 50,000 to 100,000 IU of vitamin D3 weekly (equivalent to approximately 7,100 to 14,300 IU daily) for 12 months in patients with vitamin D deficiency. The results showed that such dosing was safe, with no occurrence of hypercalcemia or other adverse effects.

When and how to take D3K2?
It is best to take the supplement in the morning or at lunch with a meal containing fat, as both vitamins are fat-soluble. Avoid taking it in the evening, as higher doses of vitamin D may affect sleep quality in some people.
Who is this supplement best suited for?
D3K2 is suitable for people with low vitamin D levels, people at increased risk of osteoporosis (e.g. women over 40), seniors, athletes, people with autoimmune diseases, and anyone who wants to preventively support immunity, bones, and the cardiovascular system.
What does the D3K2 product contain?
Each capsule contains 10,000 IU of vitamin D3 (cholecalciferol from lanolin), 200 μg of vitamin K2 (MK-7 from natto fermentation), in MCT oil, encapsulated in a softgel made from bovine gelatin, glycerin and purified water.
Dakujem za balicek, prisiel v poriadku pekne zabaleny. Vitaminy som si kupila pretoze obsahuju vysoku davku D3K2 ktore uzivam na bolest klbov a reumatizmus. Je to velke balenia ktore vydrzi za dobru cenu. Odporucam!
Cielene som hľadal vysokú dávku na trhu pretože som vysoko deficitný v D3 a lekárka mi odporučila dlhodobo užívať vyššie dávky. Odporučila mi ich na imunitu a tento produkt má super dávky D3 aj K2. Kapsuly sa dobre prehltaju, su menšie a to mi vyhovuje. Balenie vydrží dlho 70 kapsulí mám na 2,5 mesiaca čo je aj skvelá cena. Určite objednám znova.
