MK7 all-trans, in coconut MCT oil
The vitamin K2 is present as menaquinone-7 in the all-trans configuration. Both fat-soluble vitamins are dissolved in coconut MCT oil.
In summer your skin makes vitamin D — as long as the sun is high and you are outdoors. During an office winter from October to March, neither tends to be true. That is exactly when it pays to keep an eye on your vitamin D status, without having to think about another capsule every single morning.
This is where the depot principle comes in. Vitamin D3 and K2 are fat-soluble and are stored in the body. That is why one concentrated capsule every five days replaces a daily dose here. Vitamin D3 supports the uptake of calcium, while vitamin K2 is needed for the function of vitamin-K-dependent proteins — two micronutrients that meet in calcium and bone metabolism.
Dr. Wunder produces in Graz following the pure-substance principle: only the actives plus carrier oil, with no additives, colourings, flavourings or preservatives. The vitamin K2 comes as MK7 in the all-trans form — the isomer described in research as carboxylation-active.

Why vitamin D3 and K2 as a duo?
Both vitamins touch the same metabolic area. Vitamin D supports the absorption of calcium from food, while vitamin K is needed to activate vitamin-K-dependent proteins. Vitamin K contributes to the maintenance of normal bones and to normal blood clotting. Anyone taking vitamin D at higher doses therefore often combines it with K2 — as in this supplement.
What does "MK7 all-trans" mean?
Vitamin K2 exists in several forms. MK7 (menaquinone-7) has a long side chain and stays measurable in the blood longer than short-chain variants. That side chain can be arranged differently in space — as a cis or an all-trans isomer. Only the all-trans form is regarded in research as biologically carboxylation-active. This product uses all-trans exclusively.

💬 Frequently asked questions
-
How do I take the capsules?+
One capsule every five days, with water. You can take it with a meal or independently of meals. Please do not exceed the stated intake.
-
Why does one capsule last five days?+
Vitamin D3 and K2 are fat-soluble and are stored in the body. One concentrated capsule per five days corresponds to 25 µg vitamin D3 and 40 µg vitamin K2 per day. The depot principle removes the need for a daily dose.
-
Are the capsules vegan?+
No. The vitamin D3 (cholecalciferol) is obtained from lanolin — the wool grease of sheep. The capsule shell itself is plant-based (corn starch, glycerol, water). Anyone following a strictly vegan diet should choose a vitamin D3 sourced from lichen.
-
Gluten-free and lactose-free?+
Yes. The product is free from gluten and lactose and contains no additives, colourings, flavourings or preservatives. It is also suitable for diabetics.
-
What sets MK7 all-trans apart from other K2?+
MK7 is a long-chain form of vitamin K2. It can occur as a cis or an all-trans isomer, and only the all-trans form is described as carboxylation-active. This product contains all-trans MK7 only.
-
Who is the product intended for?+
For adults who want to keep an eye on their vitamin D status across the year. The product is suitable for diabetics. Anyone on long-term medication should consult their doctor before use.
