Vitamin ManufacturingMulti-Vitamin & D32K MOQ USA
From essential daily vitamins to targeted therapeutic stacks — pharmaceutical-grade potency, bioavailability-optimized, and built for the speed of modern eCommerce.
Potency the Body
Actually Absorbs
A label claim only matters if the nutrient reaches the bloodstream. We formulate with methylated B-vitamins, chelated minerals, and liposomal delivery — then verify every batch with HPLC potency assays and USP dissolution testing.
USP-Grade Inputs
Methylated B-Vitamins
Chelated Minerals
Stability-Tested
Not All Vitamins
Are Created Equal
The form of a nutrient often matters more than the dose. We default to research-backed bioavailable forms so your label claims translate into actual blood levels.
Vitamin B12
What we usePre-activated form readily used by the body — no methylation step required, ideal for MTHFR variants.
Folate
What we useBypasses MTHFR conversion. Up to 7x higher plasma folate vs. synthetic folic acid.
Vitamin D
What we useD3 raises serum 25(OH)D roughly 2x more effectively than D2 and stays elevated longer.
Vitamin K2
What we useMK-7 stays active in circulation up to 72 hours — pairs cleanly with D3 for bone and arterial support.
Magnesium
What we useChelated forms are gentle on the gut and deliver clinically meaningful magnesium uptake.
Iron
What we useComparable absorption with dramatically fewer GI side effects — critical for prenatal and women's formulas.
Zinc
What we useChelated zinc shows higher serum and erythrocyte concentrations in head-to-head studies.
CoQ10
What we useAlready-reduced form, especially relevant for consumers 40+ whose conversion capacity declines.
Custom request? We also stock branded, patented ingredients including Quatrefolic®, Albion® minerals, Bioperine®, K2VITAL®, BioPQQ®, and AstaPure® — ask your account manager about IP-protected forms for clinical claims.

Vitamin Manufacturing,
Answered Honestly
What's the real MOQ for a custom vitamin formula?
+
Our standard minimum is 2,000–2,500 units per SKU for capsules, tablets, and softgels. Gummies start at 2,500 units. Single-ingredient vitamins (e.g. straight Vitamin D3 or B12) can sometimes run at the lower end, while complex multivitamins with 20+ actives may need 2,500 to hit fair per-unit pricing.
Do you add overage to protect potency through shelf life?
+
Yes. Most vitamins — especially Vitamin C, B-vitamins, Vitamin A, and Vitamin D — are formulated with an overage above label claim so that the product still meets 100% of label at the end of its stated shelf life. The exact overage is set per nutrient based on stability data and FDA expectations.
How long do vitamin formulations stay stable?
+
Standard shelf life is 24 months for capsules and tablets, 18–24 months for softgels, and 12–18 months for gummies. We run accelerated stability under ICH guidelines (40°C / 75% RH) and real-time stability so the expiration date on your label is defensible — not guessed.
Are your vitamins USP-grade? Are they USP Verified?
+
We source USP-grade raw materials wherever a USP monograph exists, and we manufacture to USP <2091>, <2021>, and <2022> standards for weight variation, microbial limits, and disintegration. Full USP Verified certification on the finished product is a separate program — we can manufacture to that standard on request for an additional fee.
Can you handle custom multivitamins with proprietary blends?
+
Yes. Our R&D team builds custom multivitamin and multi-mineral formulas from scratch — including methylated B-complexes, prenatals, men's/women's 50+ formulas, and condition-specific stacks. We handle compatibility (e.g. separating iron from calcium), excipient selection, and label compliance for proprietary blends.
Do you offer organic, non-GMO, or vegan vitamins?
+
Yes to all three. We run dedicated vegan capsule lines (HPMC), source non-GMO Project Verified inputs where available, and can produce certified organic vitamin formulas through our organic-certified production cells. Allergen-controlled runs (no gluten, soy, dairy) are standard.
Can you do label design, packaging, and Amazon-ready prep?
+
Yes. We provide in-house label design (FDA-compliant Supplement Facts panels), bottle/blister/sachet packaging, full FNSKU/barcode labeling, shrink-banding, case packing, and Amazon-ready palletization. One vendor, raw material to inbound shipment.
What's the lead time from formula approval to finished goods?
+
4–6 weeks is our standard for vitamins in stock formats once your formula, label, and packaging are approved. Custom raw material sourcing or specialty actives can extend that to 8 weeks. Rush production is available on a case-by-case basis.
