D3 and K2

One strip, not two bottles

Take it every day without thinking about it. And stop running a two-bottle routine to do it.

Open the cupboard above the kettle. The vitamin D is in there somewhere behind the paprika, in a bottle you bought in February, still most of the way full.

You did not stop believing in vitamin D. You stopped seeing the bottle. It moved to the second row, then the back, and now it is a thing you remember on the drive to work and forget again by the time you are home.

A supplement you own and do not take is not a supplement. It is a jar.

That is the trade you make with a softgel, and nobody puts it on the label. It is cheap per capsule — that is the number the bottle sells you. What you pay for it is a thing that lives in a cupboard, needs a glass of water, and gives you no reason to notice you took it. The number that actually matters is the mornings it does not get taken.

There is a second half to this, too. D3 is usually sold on its own. K2 is usually a different bottle at a different price, so plenty of people taking D3 every day have simply never bought it.

There is a smaller way to do this

Thirty seconds, no water

A FLXStrips CORE strip is a film about the size of a stamp. You put it on your tongue. It is gone in about thirty seconds, tastes faintly of raspberry, and that is the entire ritual.

No water. Nothing to swallow. No glass, no cap, no second bottle to open after the first one. The tin is the size of a card deck and lives in a pocket or a bag, which means taking it is not an errand you have to be standing in your own kitchen to run.

One strip. Both vitamins are in it.

What is in it, and what it is for

  • 2,000 IU vitamin D3 (cholecalciferol) — 250% DV. Helping to maintain normal calcium absorption.*
  • 120 mcg vitamin K2 (menaquinone) — 100% DV. Supporting the body's natural bone health processes.*
  • One strip, 100mg, raspberry — 30 to a tin, taken without water.
  • Nothing to swallow. No softgel, no capsule, no gummy to chew.

Per strip — serving size 1 oral strip (100mg)

The cheapest bottle in the aisle is the one you stop taking

The objection, straight on

D3 softgels are cheap. Two hundred and fifty of them for about the price of a sandwich. On a spreadsheet a strip loses that comparison, and it does not lose it narrowly.

The spreadsheet assumes you take all two hundred and fifty.

Almost nobody does. That is not a character flaw, it is what the format does to you. A softgel is invisible in a cupboard, wants a glass of water, and gives you nothing to notice when you take it. There is no moment attached to it. So it goes from daily, to most days, to the back row, to February's bottle.

A strip has a moment attached to it. It is on your tongue, it tastes of raspberry, and then it is gone. You know whether you took it today, because you felt it.

And it is one thing rather than two. No pair of bottles emptying on different weeks. No stretch where you are taking the D3 and not the K2 because the K2 does not arrive until Thursday.

This table compares handling and cost. It makes no claim about how much of any ingredient reaches the bloodstream by any route. Softgel, two-bottle and gummy figures are typical US retail ranges for those formats, not specific brands.

So yes — on price per capsule, the aisle wins and I am not going to pretend otherwise. What sixty-eight cents buys is one thing instead of two, nothing to swallow, no water, and a supplement that ends up on your tongue instead of behind the paprika.

Made properly, and provable

Third-party certified

Made in the United States in an FDA-registered, GMP-certified facility that holds NSF/ANSI 455-2 for oral dissolving films — third-party certified against a published standard, not "tested in-house." Plenty of brands in this category say the second thing and let you assume the first.

Every batch is assayed against its label claim before it ships. Ask and we will send you the certificate of analysis for the lot in your tin. I am not printing lot figures on this page, because the lot you receive will not necessarily be the lot I printed.

Try it for a month. If it is not for you, keep it.

30-day promise

Tell us within 30 days and we refund your first order in full. There is nothing to send back.

Opened tins cannot be resold, so posting them to us helps nobody. We do not ask you to justify it and we do not ask for paperwork. Refund to your card, or store credit if you would rather try a different formula. That is the whole policy.

Which means the only thing you are risking is the minute it takes to order.
