Vitamin D3 and K2 supplements: a private-label overview

Softgels and oil-based capsules, described above as typical fat-soluble vitamin formats, sit outside DAT Supply's sellable catalogue. The D3+K2 combination, and the two actives individually, are manufactured across four formats in the current catalogue: gummies (combined D3+K2), liquid drops (combined D3+K2, and single-active D3 or K2), functional jellies (single-active D3) and oral strips (single-active D3). A brief calling for a softgel or capsule format has to be re-pointed at one of the four lanes above before it can move to sampling.

This is a meaningful correction to make early in a brief, since softgels and capsules are still the format most associated with D3+K2 in the wider market. A brand owner coming from that expectation should plan around the four formats above rather than assuming a softgel line is available here.

A combined D3+K2 gummy or liquid-drop SKU keeps a range to a single product and a single serving occasion, which suits a brand wanting the simplest possible bone-health or wellness SKU. Pairing a standalone D3 SKU — available in liquid drops, functional jelly or oral strip — with a standalone K2 SKU in liquid drops instead lets a brand differentiate serving format per active, which can suit a range built around more than one consumer occasion.

The choice also affects personalisation scope: a combined SKU's Make it Yours adjustments apply to both actives at once within that format's base recipe, while two single-active SKUs can each be personalised independently, including landing on different formats for each active if the range calls for it.

D3+K2 sits within the Daily Vitamins category alongside other single- and multi-active SKUs already in the catalogue, including standalone vitamin C, a zinc-and-magnesium combination and standalone magnesium SKUs. A D3+K2 SKU built in one of the four formats above can anchor a broader daily-vitamins range, with adjacent actives added in matching or complementary formats as the range grows.

Reviewing how those adjacent actives are positioned — see the sibling overviews linked below — is a useful reference point before finalising a D3+K2 brief, since it shows how other actives in the same category have been mapped onto the same sellable-format constraints.

The briefing steps described above — target dosage per serving, preferred format, K2 form and ratio — still apply, but naming a sellable format up front (gummy, liquid drop, functional jelly or oral strip, combined or single-active) rather than a generic 'capsule or softgel' preference speeds up the formulation review that follows, since the manufacturer can route the brief directly to the right format's base recipe instead of first redirecting a capsule-framed brief to a sellable alternative.

It also helps to flag early whether the brand is aiming for one combined SKU or two single-active SKUs, since that decision affects both the personalisation scope and the number of specification sheets the project will generate later. Naming the format and the combined-versus-paired choice in the same brief message, rather than across separate follow-up emails, is usually enough for the manufacturer to return a first formulation direction without a clarifying round trip. It also gives the manufacturer's R&D team a clearer starting point when a D3+K2 concept sits alongside other actives in the same range, since format and pairing decisions made here tend to shape the format choices made for the rest of the range too.
