Standards and testing
Made in the USA in a cGMP-registered facility. Independent testing begins with Lot 001 — no lot has been produced yet, so there is no certificate to show you, and we will not imply otherwise. When it exists it will be linked from this page and findable by the lot code on the bottle.
When you can order
Not yet. The buy button is a notify form because nothing can ship and we are not taking card payments until it can. Leave an email and you will hear the day stock lands.

What’s inside
One dose, taken apart.
Most supplements hide their actives inside a proprietary blend. This bottle has four facts in it — and they are all on the label.

Exactly as described. Docking one star only because the bottle is much larger than it needs to be for the count inside.
Softgel is tiny and completely tasteless. Label tells you the K2 form, which is the detail I was checking for.
Both actives declared separately with their own amounts. That is harder to find than it should be.

Questions
Frequently asked
Common questions about Vitamin D3 + K2
What does single-ingredient actually mean?
One active compound per bottle, at one dose, printed on the front panel. No proprietary blends, no undisclosed filler amounts, no second active hiding behind a trademarked name.
Do you publish test results?
Not yet. No lot has been produced, so there is nothing to test. Independent testing begins with Lot 001, and each lot's certificate will be linked from its product page and findable by the lot code printed on the bottle. Until then, everything we claim is printed on the front panel and can be checked by reading it.
Why is the dose on the front of the label?
Because it is the number that decides whether a product does anything. Putting it on the front removes the choice to bury it.
When can I actually order?
Not yet. Lot 001 has not been produced, so nothing can ship and we are not taking card payments — that is why the buy button is a notify form. Leave an email and you will hear from us the day stock lands, with the shipping timetable at that point.

Read the label. Then decide.
