Vitamin D3 and vitamin B12 are widely co-formulated in multinutrient, vegan nutrition, bone wellness, immune wellness, and energy-positioned supplement products, but they are usually sourced, weighed, verified, and blended as two separate ingredients. This creates a practical formulation challenge: vitamin D3 is oil-soluble and sensitive to light and oxidation, while vitamin B12 is used at microgram levels and requires careful distribution, light protection, and assay control during premix and finished dosage production. Formulators must manage two specifications, two certificates of analysis, two handling requirements, and low-dose blend uniformity risk before the finished product can be released.
DuoZeal is a co-encapsulated vitamin D3 and B12 premix powder developed for direct incorporation into capsules, tablets, gummies, sachets, stick packs, and premix formats. The powder format is designed to simplify low-dose vitamin handling, reduce separate weighing and pre-dilution steps, and support more consistent distribution of both actives within a single documented ingredient system.
Formulators evaluating a co-encapsulated D3 and B12 ingredient need to confirm potency of both actives, blend uniformity, powder flow, and compatibility with their target dosage format. A development sample of DuoZeal is supplied with batch-level D3 and B12 assay, allergen and vegan declarations, and a Technical Data Sheet with suggested evaluation guidance by dosage format.
Available version - DuoZeal Standard. The standard D3 to B12 ratio is confirmed on the product specification and Certificate of Analysis supplied with each development sample and commercial batch. Custom ratios can be developed based on customer formulation requirements.
Combines D3 and B12 into one premix-ready ingredient, reducing separate weighing, pre-dilution, and handling steps during production.
Designed to help manage B12 distribution at microgram dosage levels, where insufficient pre-dilution can create blend-uniformity risk.
Replaces two separate vitamin inputs with one co-processed system, reducing purchasing, specification, and documentation complexity.
