Why is the combination so popular?
The essential micronutrients vitamin D3 and vitamin K2 work closely together in the body - especially when it comes to bone health and the blood. While vitamin D3 (cholecalciferol) supports the absorption of calcium in the intestine, vitamin K2 (especially in the form MK-7) is supposed to ensure that this calcium ends up where it belongs: namely in the bones and teeth - and not in the arteries.
However, this has not yet been scientifically proven and further research is required. Nevertheless, this combination can be useful.
Who is the
D3K2 combination suitable for?
The combination of vitamin D3 and K2 is relevant for many people - especially for target groups with an increased need or an increased desire for prevention:
- People with little exposure to sunlight (e.g.office workers, shift workers, elderly persons)
- Menopausal women, as bone health is a particular focus here
- Senior citizens, to maintain bone stability
- Athletically active people who want to specifically protect their bone substance
- Vegetarians / vegans, as vitamin D3 and K2 are often not consumed in sufficient quantities in the diet
- People with an increased calcium requirement
In short: The D3K2 combination is a real all-rounder that can be used in many situations in life.
