PRIVATE LABEL & CUSTOM FORMULATION

Private Label Vitamin D Drops for Your Brand

Quote an existing specification, revise a formula or start a new vitamin D drops brief.

Bring an existing vitamin D drops specification or a new product concept. Discuss D3-only or D3 + K2, the proposed serving concentration, carrier and finished bottle/dropper for your destination market.

Send your target country, intended user group, estimated quantity and any bottle or label preferences. If the formula is incomplete, identify what needs review. We will respond within 48 hours to discuss the brief; feasibility, samples and supply terms are confirmed separately.

PRODUCT DEVELOPMENT

Choose the brief for your vitamin D drops project

Have a specification ready for quotation review? Send the D3-only or D3 + K2 direction, ingredient forms, amount and unit per serving, carrier, bottle/dropper, estimated quantity and destination country. Mark which items are fixed and which alternatives you would consider, so any proposed supply can be compared against the same brief.

Updating an existing product? Share a label or specification you are entitled to use and identify the changes you want reviewed, such as the vitamin combination, serving concentration, carrier or dispensing format. Separate the elements you want to retain from those you want to change; a reference product does not confirm an identical formula or supply.

Starting from an idea? Send your destination country, intended users, D3-only or D3 + K2 preference and estimated quantity, and mark undecided details as open. You do not need a complete formula to start a discussion. The specification, sample scope and supply terms require project-specific confirmation.

PROJECT DETAILS

Turn the vitamin choice into a clear product specification

NIH distinguishes vitamin D2 and D3 as different forms. Specify the form you want reviewed rather than using “vitamin D” as the entire ingredient brief. Requests for children or infants need a separate formulation and suitability review.

Vitamin combination
D3 alone or D3 + K2; identify the requested ingredient forms.
Serving and concentration
Proposed amount per serving, serving size and concentration per volume.
Carrier and flavor
Preferred carrier, flavor direction and ingredients to exclude.
Bottle and dispensing
Fill volume, bottle material, dropper or dispensing preference and label dimensions.
Market and users
Exact destination country, intended user group and sales channel.

CUSTOMIZATION

Your idea. A coordinated process.

01

Review the bottle, serving instructions and artwork together

A proposed amount per drop is not the same specification as an amount per milliliter. Agree how the serving will be measured and which dispensing device the sample represents.

Use the sample review to check the agreed product experience and package: appearance, flavor, dispensing, fill presentation and label fit. Ask what testing and stability evidence will support the proposed composition, storage instructions and shelf life.

02

What should your vitamin D drops quotation include?

Ask for the formula and finished pack to be identified in the quotation: ingredient combination, serving specification, fill volume, bottle/dropper, label and packing. Confirm whether formulation work, samples, testing, documents and freight are included or quoted separately. Use the same specification and delivery basis when comparing offers.

Before approving a sample or order, agree the formula and packaging versions, quantities, applicable documents, MOQ, sample costs and schedule in writing. Our initial project response is within 48 hours; a completed quotation, sample or production date requires separate confirmation.

03

Documents to discuss before approval

Share the files your importer or label reviewer requires. Discuss the product specification, relevant ingredient identities, applicable testing and a COA for the selected supply where available.

Document availability and scope are checked for the product and destination. A general supplier certificate does not establish that every formula is covered. Review supplied certificate copies →

Match the documents to your custom project.

Tell us your destination, vitamin combination, bottle preference and any certificate or testing requirements. Existing system or facility documents do not establish certification, testing or market eligibility for a new formula.

YOUR NEXT STEP

Start your vitamin D drops quotation brief

01

Define your brief

Destination country, D3-only or D3 + K2 direction, and estimated quantity if known.

02

Review the specification

Formula and bottle/dropper details, sample scope and documents to confirm after the first discussion.

You can start before your formula or artwork is complete. Send the information you know and mark the rest as undecided. We respond within 48 hours to discuss the project; quotation scope, feasibility, samples and supply terms are confirmed separately.

Before you inquire.

Can I discuss D3-only drops on this page?

Yes. State D3-only or D3 + K2 in your brief. The ingredient combination, requested forms and specification are reviewed for the selected project.

What if I do not have a complete formula?

Start with the destination country, intended user group, vitamin combination, estimated quantity and any packaging preferences. Mark undecided details as open for discussion.

Can I request a different carrier or dispensing format?

Include the requested change and any ingredient exclusions. Compatibility, packaging availability and sample scope need project-specific review.

When will I know the MOQ and sample schedule?

Ask for written confirmation after the formulation route, package and sample scope have been reviewed. This page does not establish a product-specific MOQ or sample date.

What should I send for the first discussion?

Your country, D3-only or D3 + K2 direction, proposed serving strength if known, packaging preference and estimated quantity. Include a draft label or reference specification if available.
