We've made a deliberate environmental decision: rather than throwing away perfectly good CalClear sachets just because their printed date code is out of date, we've reused the old packaging — and filled each sachet with the new, in-date batch of supplement.
The formula hasn't changed. The quality control hasn't changed. Every sachet you open contains the same CalClear blend of Vitamin K2 as MK-7, Vitamin D3 and magnesium, made to the same specification and put through the same batch testing we've always done — raw material certificates of analysis, fill-weight checks, seal integrity, and finished-product testing. The only thing that's different is the age of the sachet the supplement is sitting in.
What this means for you:
— The printed date on the sachet may look out of date. It isn't lying; that sachet was originally printed a while ago.
— The supplement inside is from the current, new production batch and is fully in date.
— The formula and quality checks are identical to every previous run of CalClear — nothing has been changed or compromised.
— We made this call to keep a lot of sachet material out of landfill. We'd rather reuse good packaging than print fresh sachets just for the sake of a newer-looking date code.
What's coming next: demand for CalClear has picked up significantly, so we're moving to a system where every reused sachet will carry a new date-code sticker on top of the old print, showing the true fill date and best-before of the supplement inside. Those stickers will roll out on sachets leaving our warehouse soon. Until then, the paragraph above is the rule: old printed date on the sachet, new batch inside.
Same formula, same quality control — every single sachet
We want to be crystal clear on this point because it's the thing that matters most. Every sachet of CalClear, whether it's in fresh packaging or in a reused sachet, contains:
— The same K2 as MK-7 (the longer-lasting, fermented chickpea-derived form), at the same dose
— The same Vitamin D3, at the same dose
— The same magnesium, at the same dose
— Manufactured in the same UK facility, to the same GMP standard
— Tested to the same finished-product specification before it leaves our warehouse
Nothing about the supplement itself has changed. The environmental decision is purely about the outer packaging — not the product you're taking.
How to confirm the true best-before date of your sachet
If you'd like absolute certainty, email us the L-code printed on your sachet (for example L2601A) and we'll reply with:
— The actual fill date of the supplement inside
— The true best-before date for that supplement
— Which production run it came from
We reply the same working day.
Why we reused the sachets instead of reprinting them
Every production run we do has to make a call: pulp perfectly good sachet material and reprint it with a fresher-looking date, or reuse what we already have and fill it with the new batch. We chose reuse. Across a year of production that's a meaningful amount of material kept out of the waste stream, and the supplement inside is identical either way. We'd rather be up front with customers about why the printed date doesn't match the actual freshness of the supplement than create unnecessary packaging waste just so the label "looks right."
The date-code sticker rollout
Because orders have ramped up faster than expected, we're now introducing a new date-code sticker that will be applied on top of the old printed code on every reused sachet. The sticker will show the current batch's fill date and best-before. That way you get the environmental win of reused packaging and an at-a-glance confirmation of the real date on the label. We're working through the logistics now and will have the stickered sachets out the door soon.
How to read the old printed date code
The printed code on the sachet usually looks something like:
L2601A · BB 06/2028
Broken down: L = lot prefix, 26 = year, 01 = week of manufacture, A = production line, BB 06/2028 = best-before originally printed on that sachet. Remember — on a reused sachet, that printed code refers to when the sachet was originally made, not to the supplement currently inside it.
Why "best before" is more forgiving than you think
"Best before" is not the same as "use by." After the best-before date, the supplement doesn't suddenly become unsafe — it just means we can no longer guarantee every dose is at the full labelled potency of K2 MK-7, D3 and magnesium. The ingredients are stable; what degrades over time is strength, not safety.
How to store CalClear so the supplement lasts
Keep sachets cool and dry. A kitchen cupboard away from the oven or kettle is ideal.
Don't open a sachet until you're ready to use it. K2 MK-7 and D3 are fat-soluble and sensitive to prolonged air exposure — the sealed sachet protects them until you're ready.
Keep sachets in their outer carton or pouch. This keeps light off the print and stops sachets getting crushed in a drawer.
Frequently asked questions
The printed date on my sachet is in the past — is the supplement really still in date?
Yes. See the top of this page: we reused older printed sachets to reduce packaging waste, and the supplement inside is from the current, in-date batch — same formula, same quality control. Email us the L-code and we'll confirm the true fill and best-before dates.
Has anything about the formula changed?
No. CalClear's formula, dosing, sourcing and quality control are identical across every batch. The only change is the age of the sachet the supplement sits in.
Why didn't you just print new sachets?
Because it would have meant throwing away perfectly good packaging. The environmental impact of reprinting a run just for the sake of a fresher date code isn't something we were comfortable with. Reusing the sachets is the more responsible call.
When will the new date-code stickers arrive?
Very soon. Demand has picked up faster than expected, which is why we're adding a sticker showing the true current-batch date on top of the old printed code. It's being rolled into production now.
Is CalClear suitable for vegetarians?
Yes — the MK-7 form of Vitamin K2 we use is from a fermented chickpea source.
What if the printed code on my sachet is smudged or unreadable?
Email us a photo of the sachet and we'll identify the batch from the artwork. The sachet seal is tamper-evident; if it was intact when you opened it, nothing inside has been compromised.
Any questions? Just ask.
Email us the L-code from your sachet and we'll come back to you the same working day with the exact fill date and best-before of the supplement inside. We'd rather answer a quick email than have anyone taking a supplement they aren't sure about — and we want you to know, every sachet you open is the same CalClear you've always trusted.
