D3 raises how much calcium you absorb. K2 decides where it goes.
Vitamin D3 increases calcium absorption from your gut. Vitamin K2 is the cofactor that activates osteocalcin and matrix Gla protein — the two proteins that direct that calcium into bone. Take D3 on its own and you have raised the supply without supporting the routing step. That is why the pair is the product.†
Why MK-7 and not MK-4. There are two forms of K2 on the market. MK-4 clears from the blood within hours, which is why products using it need several doses a day. MK-7 stays in circulation substantially longer, so one millilitre a day is enough to keep levels steady.†
Why an oil base. D3 and K2 are both fat-soluble. Suspended in MCT oil they arrive with the fat they need, and a dropper lets you take a partial dose if your clinician wants you lower.†
One millilitre, once a day.
Shake well before use — the vitamins are suspended in oil and will settle. Take 1 mL straight, or stirred into water, coffee or a smoothie. Taking it with a meal that contains some fat is ideal but not essential, since the carrier is already an oil.
Same time each day is what matters most. A 60 mL bottle is 60 servings — two months.

If you take warfarin or another coumarin anticoagulant, talk to your prescriber before you start or stop this product. Vitamin K directly opposes how those medicines work, and starting or stopping it will move your INR. This is not a reason you cannot take it — it is a reason your prescriber needs to know.
5,000 IU a day sits above the 4,000 IU adult upper intake level set by the National Academy of Medicine. That is not a legal limit and 5,000 IU is widely sold, but it does mean this is a deliberately high-dose product rather than a maintenance one. If you take it long term, having your vitamin D level checked is sensible.
Speak to a clinician first if you take calcium supplements, a thiazide diuretic or digoxin, or if you have kidney disease, sarcoidosis or another granulomatous condition — high-dose vitamin D can raise blood calcium.
Not for children. If you are pregnant or breastfeeding, confirm the dose first.
Try it without risk.

HALF THE JOB
D3 is the part that raises how much calcium you absorb. K2 is the part that activates the proteins which route that calcium into bone. Most D3 products sell you the first half and stop. If any of this sounds like your winter, the pair is worth taking together.†

Darker skin, which makes less vitamin D from the same sun

MK-7, NOT MK-4
MK-4 clears the blood within hours, which is why products built on it need dosing several times a day. MK-7 stays in circulation substantially longer — so one millilitre a day holds levels steady. It costs more. We used it anyway.†

Getting Established
Shake, take your 1 mL, same time each day. Vitamin D builds up in the body rather than acting on the day you take it, so this stretch is about the habit, not a feeling.†
Weeks 3–8
Levels Climbing
Blood levels of vitamin D rise gradually and take roughly eight to twelve weeks to reach a steady state at a fixed daily dose. Keep going — stopping and restarting is what wastes the effort.†
Weeks 9–12
The Fair Test
By now a daily dose has had time to do what it is going to do. This is also the point at which a blood test actually means something — and the window our 90-day guarantee covers.†

Frequently Asked Questions
Shake the bottle well, then take 1 mL once a day — straight, or stirred into water, coffee or a smoothie. A 60 mL bottle is 60 servings, so one bottle is two months.
D3 increases how much calcium you absorb. K2 activates the proteins — osteocalcin and matrix Gla protein — that direct calcium into bone. Supplying more calcium without supporting the step that routes it is doing half the job, which is why we put both in one bottle.†
They're both vitamin K2. MK-4 leaves the bloodstream within hours, so products using it generally need several doses a day to hold a level. MK-7 has a much longer half-life, which is why once a day works here. MK-7 is the more expensive raw material.†
It is a high dose, and we'd rather say so than bury it. The adult upper intake level set by the National Academy of Medicine is 4,000 IU a day; 5,000 IU sits above that. It isn't a legal limit and 5,000 IU is sold very widely, but it does mean this is a corrective dose rather than a maintenance one. If you're taking it for months, ask for a vitamin D blood test — and if you want to go lower, the dropper lets you take half.
If you take warfarin or another coumarin anticoagulant, speak to your prescriber first. Vitamin K works directly against those medicines and starting or stopping it changes your INR. Also check first if you take calcium supplements, a thiazide diuretic or digoxin, or if you have kidney disease, sarcoidosis or another granulomatous condition, because high-dose vitamin D can raise blood calcium.
Honestly — you may not feel anything, and that isn't a failure. Vitamin D corrects a level rather than producing a sensation. Blood levels take roughly eight to twelve weeks to settle at a fixed daily dose, which is why our guarantee runs 90 days and why a blood test is the only real answer to this question.†
