FAQ

Why MK-4 instead of MK-7?+

MK-4 is the form of K2 that tissues (bones, vessels, brain) use directly, without conversion. It absorbs quickly: it reaches the bloodstream within 1-2 hours. MK-7 stays in the blood longer, but tissues still need to process it. For daily use, MK-4 is more effective.*

Why take D3 and K2 together?+

D3 helps you absorb calcium from food. K2 directs that calcium into bones and teeth, rather than into vessel walls.* That's why the formula is built as a duo — otherwise calcium can settle in the wrong places.

Why a spray instead of capsules?+

Fat-soluble vitamins are well absorbed through the mucosa under the tongue. The spray enters the bloodstream directly, bypassing the digestive tract. This means it works without a capsule or gelatin, in a clean MCT oil base.

How long does one bottle last?+

60 servings — about 2 months with daily use. A monthly subscription ensures you never run out.

Is it suitable for children, pregnant, or breastfeeding women?+

Daily values for D3 and K2 depend on age and condition. Specific doses for children and pregnant or breastfeeding women are best discussed with a doctor or nutritionist — we don't make individual recommendations. General RDAs by age are on the daily needs page.
