Vitamin Contract Manufacturer for Custom & Private Label Supplements
Gensei Global manufactures custom and private label vitamin supplements for international nutrition brands. We translate single-vitamin, B-complex, D3+K2, and multivitamin-mineral concepts into compressed tablets, hard capsules, softgels, gummies, chewables, and powder blends—supported by stability engineering, pilot sampling, and turnkey retail packaging.
Final formulation specifications, overage targets, commercial quotations, and production schedules are confirmed per approved product brief.
Choose the Right Manufacturing Route
Whether your brand has a locked-in Supplement Facts panel or an early product concept, we align active vitamin forms, daily serving size, dosage format, and destination-market compliance before production.
Manufacture Your Formula
Submit your existing Bill of Materials (BOM), label claim targets, and excipient preferences. We audit vitamer grades, active loading feasibility, process compatibility, and assay methods.
Develop a Vitamin Supplement
Engineer a custom single-vitamin or multivitamin formula around your target demographic, bioavailable nutrient forms, taste/swallowability goals, and optimal delivery format.
Prepare Your Branded Line
Select from established vitamin formulations and customize unit counts, bottle/blister/pouch packaging, flavor directions, and market-ready private label artwork.
Vitamin C, B-Complex, D3+K2 & Multivitamin Projects
Selecting the right chemical form (vitamer) and raw material grade determines tablet compressibility, capsule fill volume, oxidative stability, and label claims.
Multivitamin & Multimineral
Daily A-to-Z nutritional formulas balancing 15–25+ micronutrients. We use microencapsulated vitamins and chelated minerals (bisglycinates/citrates) to minimize cross-oxidation and control tablet/capsule size.
Vitamin C Formulas
High-load Ascorbic Acid, DC 97% direct-compression granules, buffered Sodium/Calcium Ascorbate, or Liposomal Vitamin C—engineered with acidity control for chewables, gummies, powders, and tablets.
Vitamin D3 & K2 Combinations
Lanolin or vegan lichen Cholecalciferol (D3) paired with microencapsulated all-trans MK-7 (K2) in MCT/olive oil softgels, dry-filled capsules, or stabilized micro-tablets.
Active B-Complex & B12
Standard or methylated B-vitamin complexes featuring Methylcobalamin / Cyanocobalamin (B12), Pyridoxal-5-Phosphate (P-5-P B6), 5-MTHF Folate, and D-Biotin with targeted odor and moisture barriers.
Fat-Soluble Vitamins A & E
Retinyl Palmitate, natural Beta-Carotene, and natural d-alpha Tocopheryl Acetate (oil for softgels) or d-alpha Tocopheryl Succinate (dry powder for two-piece capsules and tablets).
Condition-Specific Blends
Immune, prenatal, hair/skin/nails, energy, and bone-health formulas combining targeted vitamins with botanical extracts, amino acids, or coenzymes (CoQ10) around your target serving size.
Vitamin Stability, Compatibility & Potency Planning
Vitamins vary widely in sensitivity to heat, humidity, oxygen, light, and pH. Our R&D team aligns raw material coatings, processing temperatures, and barrier packaging so your product meets label claims through shelf life.
Vitamer & Mineral Isolation
Prevent transition metals (iron, copper, zinc) and alkaline excipients from accelerating the degradation of Vitamin C, B1, B12, and K2 (MK-7) by selecting coated or microencapsulated raw materials.
Scientific Input Overages
Formulate appropriate manufacturing overages for heat- and moisture-sensitive vitamins (especially in cooked pectin gummies and compressed tablets) to account for processing and storage decay.
Moisture, Oxygen & UV Control
Pair hygroscopic and light-sensitive formulas with aqueous film coatings, opaque softgel shells, amber PET/HDPE bottles, silica gel desiccants, or Alu-Alu / PVDC blister foils.
Active Payload Matching
Match total milligram/microgram active weight to the right physical format—avoiding oversized tablets or under-dosed gummies by balancing serving counts and excipient ratios.
Target input overages, HPLC / Titration / ICP-MS analytical assay methods, and accelerated or real-time stability protocols are customized and documented for each approved formula.

Häufig gestellte Fragen zur Auftragsfertigung von Vitaminen
Direct answers for supplement brand owners, formulators, and sourcing teams.
Can Gensei manufacture vitamin supplements across different dosage forms?
Yes. Depending on active payload weight and ingredient stability, we manufacture vitamin formulas as compressed tablets, two-piece hard capsules (gelatin/HPMC/pullulan), oil-filled softgels, pectin/gelatin gummies, chewable tablets, effervescent tablets, and dry powder blends.
Can I transfer my existing multivitamin formula or Supplement Facts panel?
Yes. Send us your Bill of Materials (BOM) or Supplement Facts panel along with your target dosage form and serving size. Our R&D team reviews vitamer forms, excipient compatibility, and input overages before preparing pilot samples.
What is the MOQ for vitamin tablets, capsules, and softgels?
Our standard starting MOQ is 100,000 units per SKU for compressed tablets, chewable tablets, hard capsules, and softgels (for example, ~1,660 bottles at 60 counts per bottle). Custom tooling or specialty imported raw materials may have specific minimum requirements.
What are the MOQs for vitamin gummies and powder blends?
Powder vitamin blends start at 100 kg per formula and flavor (with 100–300 g lab samples). Vitamin gummy minimums depend on piece weight, pectin/gelatin base, and mold configuration—typically starting around 150,000+ gummies per SKU.
How do you handle vitamin degradation, potency overages, and shelf life?
We select stabilized or microencapsulated raw materials (such as microencapsulated MK-7 and coated Ascorbic Acid), isolate reactive minerals, calibrate scientific input overages for heat- or moisture-sensitive actives, and pair the product with appropriate barrier packaging.
How long do vitamin sampling and bulk production take?
Lab sampling typically takes 7–15 working days for hard capsules, 2–3 weeks for tablets, gummies, and powders, and 2–4 weeks for softgels. Commercial bulk production generally takes 6–8 weeks for solid dose/softgel/gummy runs and 4–6 weeks for powders after material readiness and approvals.
