Private Label Liquid Vitamin D3 & K2, 0.5oz

Private Label Liquid Vitamin D3 & K2 for Combination Vitamin Lines

Private Label Liquid Vitamin D3 & K2 is a 0.5 oz liquid supplement combining two named actives, vitamin D3 and vitamin K2, in a single drop-format bottle. It is produced to order in a GMP-certified facility in Hauppauge, New York, with flexible minimums, custom packaging and formulation support from concept through finished goods.

A two-nutrient bottle is a different commercial proposition than a single-vitamin SKU: it consolidates what many customers would otherwise buy as two products, which supports a higher unit value and a cleaner regimen story. This one fits combination vitamin lines, bone and structural wellness ranges, practitioner and clinic channels where D3 and K2 are routinely stocked together, premium DTC brands, and subscription programs where a compact bottle keeps fulfillment costs down.

What Is a Liquid D3 & K2 Combination?

A liquid D3 and K2 combination is a single supplement that delivers both vitamins from one bottle in drop form, rather than asking the customer to buy and take two separate products. The pairing has been a standard shelf position in the vitamin category for years, which means the buyer does not have to explain the concept — only the format.

The format is where this version earns its place. Most D3 and K2 combinations on shelf are softgels, and a softgel commits the brand to a fixed capsule shell, a fixed dose, and a gelatin question in vegetarian, Kosher and Halal channels. A 0.5 oz liquid removes all three constraints: the dose is set in the fill rather than the shell, the product is available to customers who avoid pills, and the small bottle is far cheaper to ship than an equivalent count of softgels. For a brand building a combination-vitamin line, that is a more flexible platform than a capsule.

Market Demand

This SKU sells into a large nutrient category and a well-defined positioning category at the same time. Grand View Research sizes the global vitamin supplements market at USD 59.5 billion in 2025, reaching USD 106.1 billion by 2033 at a 7.5% CAGR.

Brands that position a D3 and K2 bottle toward bone and structural wellness are entering a segment Grand View Research values at USD 14.2 billion in 2024 and USD 16.2 billion in 2026, growing to USD 27.2 billion by 2033 at a 7.6% CAGR for bone and joint health supplements. Brands that take the cardiovascular positioning route instead are entering a market Grand View Research puts at USD 10.2 billion in 2024 and USD 11.9 billion in 2026, reaching USD 16.7 billion by 2030 at an 8.6% CAGR for cardiovascular health supplements. Having two credible merchandising routes from one bottle is unusual, and it is the main reason this combination keeps expanding on shelf.

Private Label Opportunity

Combination SKUs are how supplement brands raise average order value without adding fulfillment complexity. Two nutrients in one 0.5 oz bottle means one label, one carton, one lot and one shipping unit, but a retail story that justifies more than a single-vitamin price.

The private label opportunity is strongest for brands that already sell a plain vitamin D3 and want a step-up SKU, and for practitioner or clinic-channel brands whose customers expect the pairing as standard. Because potency ratio, flavor direction and certification path are all set at quote rather than fixed, one manufacturing program can produce a mass-retail version and a professional-channel version under different labels. Brands typically anchor a drop-format family around it: a D3 single, a D3 and K2 combination, and a liquid multivitamin, all in the same bottle size and visual system.

Competitive Landscape

The competing formats for D3 and K2 are overwhelmingly softgels and capsules, with a smaller set of oil-carrier sprays and tablets. Softgels dominate because they are cheap at volume, but they are also where the category is most price-compressed and least differentiated — a shelf of near-identical amber bottles competing on count.

A 0.5 oz liquid drop puts a brand in a much thinner competitive set. It answers the pill-averse customer that softgels cannot reach, it sidesteps the gelatin constraint in vegetarian, Kosher and Halal programs, and it presents as a more considered, higher-touch product on a DTC product page. Against single-nutrient liquid D3, meanwhile, the K2 pairing is the upgrade argument. This SKU is deliberately positioned in the gap between the commodity softgel and the plain liquid single.

Why Brands Choose This Formula

Brands choose this formula because it does two jobs at once: it consolidates a two-product regimen into one bottle, and it moves a heavily commoditized nutrient pairing into a format where price is not the only conversation.

The manufacturing side supports that positioning. It is made in the USA from globally sourced ingredients in a GMP-certified Hauppauge, New York facility, with NSF, USDA Organic, Kosher and Halal certification paths available against the agreed specification. Custom packaging and label design are part of the private label program, and full formulation support means the ratio between the two actives, the flavor direction and the bottle presentation are decisions the brand makes. For a company building a credible combination-vitamin line rather than reselling stock, that control is the reason this formula gets chosen.

Common Buyer Questions

What is a private label liquid vitamin D3 and K2?

It is a finished two-nutrient supplement, sold under a company’s own brand rather than the manufacturer’s, that delivers vitamin D3 and vitamin K2 from one 0.5 oz liquid bottle. BioB MFG formulates, fills and labels it to the brand’s specification so the buyer launches a branded SKU without owning a facility.

What format is this product?

It is a liquid drop supplement in a 0.5 oz bottle, not a capsule or softgel. The compact size suits subscription boxes, bundles and travel sets, and keeps shipping costs low relative to an equivalent supply of softgels.

Which vitamins are in this formula?

Two named actives: vitamin D3 and vitamin K2. Specific forms and potencies are documented on the spec sheet and confirmed at quote rather than assumed, and the ratio between them can be adjusted through formulation support.

What is your minimum order quantity (MOQ)?

Minimum order quantities vary by format. Liquid products under 8 oz start at 5,000 units; 8 oz and larger liquids start at 2,500 units. Capsule and tablet products have a minimum of 300,000 capsules or tablets total. Request a quote and we’ll confirm exact MOQ and price breaks for your project.

Can the packaging and label be customized?

Yes. Bottle, dropper or closure style, carton and the brand’s own label artwork are all customizable, and full formulation support is available for brands that want to adjust the specification rather than take it as-is.

Yes. It is made in the USA from globally sourced ingredients in a GMP-certified facility in Hauppauge, New York. NSF, USDA Organic, Kosher and Halal certification options are available and confirmed against the agreed specification during quoting.
