Why is vitamin D sold with K2?

K1 is in green leaves. K2 is a different form. Pairing them is a formula choice, not proof that a D-only drop is unsafe.

45 µg of K2 in Kids. That is 60% of the adult NRV, not a high-dose bottle

The pair is on our pouch because we put both vitamins in. Search boxes are full of a longer story, usually about calcium going to the right place. That sentence is not on the EU Register. The trials that compare the pair against either nutrient alone are few and small. Pairing them is a formula choice. It is not proof that a D-only drop is unsafe.

K1 and K2 are both vitamin K. They are not the same molecule. This page is the European table, the authorised sentences, and the arithmetic if you already give D drops.

The short answer

  • Vitamin K on a European label is measured against an NRV of 75 µg. EFSA's adequate intakes are set on phylloquinone, which is K1. There is no separate "children must have K2" line. We will not invent one.
  • Pocket Kids carries 25 µg of vitamin D3 and 45 µg of K2. Teens and Adults carry 35 µg of D3 and 120 µg of K2.
  • Vitamin K contributes to normal blood clotting and contributes to the maintenance of normal bones. Vitamin D contributes to the maintenance of normal bones and is needed for normal growth and development of bone in children.
  • If you already give vitamin D drops, add those micrograms to ours. K2 does not cancel a double D.
  • A D-only product can still be the right tool for a winter habit a GP has named. Ours is one scoop. You cannot take the K2 out and leave the rest.

K1 and K2 are both vitamin K

K1 sits in green leaves: spinach, kale, lettuce, cabbage. K2 (menaquinones, often MK-7 on packs) sits in some fermented foods. Natto is the famous one. Some cheeses carry K2 as well. A plate with leaves is not empty of vitamin K because it has no natto on it.

The form in our formula is K2 as MK-7. It still counts as vitamin K on the pack. The label does not give you a separate K1 line. If you are comparing two pouches, compare the micrograms of vitamin K, then the form if the brand bothers to name it.

We chose MK-7 as a formulation descriptor. That is not an absorption claim, and it is not a reason to buy a third bottle of K2 on top.

What EFSA actually set

EFSA's 2017 dietary reference values for vitamin K are adequate intakes for phylloquinone. The panel said the evidence on menaquinones was not enough to set a separate line. So the table below is K1. It is not a children's K2 requirement.

Age Adequate intake, phylloquinone (EFSA, 2017)
4 to 6 20 µg
7 to 10 30 µg
11 to 14 45 µg
15 to 17 65 µg
Adults 70 µg

The adult NRV on the pack is 75 µg, from Regulation (EU) No 1169/2011. 45 µg of K2 is 60% of that ruler. 120 µg is 160%. Against EFSA's K1 figure for a young child, 45 µg looks large. Against a dedicated K2 capsule of several hundred micrograms, it looks small. Read the micrograms. We chose a complement, not a specialist K2 product.

EFSA did not set a tolerable upper intake level for vitamin K. That is not an invitation to a high-dose K2 course on a blog. If a clinician has named a K2 amount for a reason, that is their product.

Green vegetables still do the K1 job. Portugal and Spain eat more leaves and more olive oil than a lot of northern weeks. That does not write a K2 requirement.

What the Register lets us say

A food supplement may only describe a health benefit in the wording on the EU Register of nutrition and health claims. When the daily dose supplies a significant amount:

Authorised wording In our product
Vitamin K contributes to normal blood clotting Yes (K2 in all three formulas)
Vitamin K contributes to the maintenance of normal bones Yes
Vitamin D contributes to the maintenance of normal bones Yes
Vitamin D is needed for normal growth and development of bone in children Yes

The word doing the work is "contributes". It does not say the pair directs calcium. It does not say a D-only drop is unsafe. There is no authorised wording that vitamin K2 "activates" vitamin D, or that the pair is required for children. The internet calcium story is not an authorised claim. We will not print it.

Pairing is a formula choice

We put two fat-soluble vitamins in one scoop because they often travel together, and because both have authorised bone wordings we may use. That is the decision. It is not a trial that compared D-plus-K2 against D alone in your kitchen.

A D-only product can be the right tool for a winter habit a GP has named. Pairing on our label does not make that drop a mistake. It makes two D sources a sum. The age guide is here. The summer version is here.

If you keep our pouch and keep the drops, add the micrograms. EFSA's long-term upper intake for vitamin D is 50 µg a day from 1 to 10, and 100 µg from 11 and in adults (EFSA, 2023). Kids already has 25 µg. Teens and Adults already have 35 µg. Last winter's drops still count. Do not buy a third K2 bottle on top unless you can name the extra amount and why.

If a clinician has you on a medicine that interacts with vitamin K, take the pouch label to that conversation. Do not guess a time of day that "avoids" the interaction. Do not stop a prescribed medicine because of a blog.

Where My Daily Pocket fits

Formula Vitamin D3 in one scoop K2 in one scoop Who it suits Who it does not
Pocket Kids (4–11) 25 µg 45 µg A daily multinutrient that includes both, if that is the job you want A high-dose K2 bottle. A D-only pause. Infants.
Pocket Teens (12–17) 35 µg 120 µg Same idea, teen amounts The same three.
Pocket Adults (18+) 35 µg 120 µg Same idea, adult amounts A specialist K2 product. Pregnancy as prenatal care.

45 µg of K2 is 60% of the 75 µg NRV. 120 µg is 160%. 25 µg of D3 is 500% of the 5 µg adult NRV. 35 µg is 700%. Add the micrograms.

We have no calcium in any of the three formulas. If the story you came in with was about calcium going somewhere, ours is the wrong pack for that sentence. We also have no iron, no vitamin A, no vitamin E, no biotin, and no omega-3. If a GP has already given you a D-only drop you are happy with, you do not have to add our pouch in order to "complete" the pair.

FAQ

Why is vitamin D sold with K2?

Often because both are fat-soluble and both have authorised wordings about bones. On our pouch it is a formula choice. It is not proof that a D-only drop is unsafe.

Do children need K2 specifically?

EFSA set adequate intakes on phylloquinone (K1). There is no separate children's K2 line. Green leaves still do that job.

What may we say vitamin K does?

In the authorised wording: it contributes to normal blood clotting, and it contributes to the maintenance of normal bones.

I already give D drops. Can I still use the pouch?

Yes, if you add the micrograms. K2 does not cancel the D. Stay inside the vitamin D ceiling for the age. The stacking page is How much is too much?.

Is this a calcium product?

No. There is no calcium in the pouch. We will not print the internet calcium story as a claim.
