What International Vitamin does

International Vitamin Corporation (IVC) is a privately held U.S.-headquartered contract development and manufacturing organization (CDMO) specializing in nutritional supplements, vitamins, and over-the-counter products. Founded in 1955 with its first manufacturing facility in Greenville, South Carolina, IVC operates 12 manufacturing facilities across the United States, Canada, the United Kingdom, Germany, and China and reports a headcount of 1,001–5,000 employees. The company is led by President & CEO Steven Dai.

IVC produces five dosage formats — capsules, gummies, powders, softgels, and tablets — and offers end-to-end services from formulation R&D and in-house analytical testing through packaging, labeling, regulatory support, and logistics. Differentiated technology includes the proprietary NutraGlide plant-based tablet coating and a continuous manufacturing process for solid-dose forms; a Universal Quality System spans all facilities. Manufacturing sites are FDA-audited and cGMP-compliant, with certifications including 21 CFR Parts 111/117/121, USP/DSVP, NSF cGMP, NSF Sports, Halal, Kosher, Organic, Non-GMO Project Verified, and Gluten Free.

The business model is B2B fee-for-service contract manufacturing on a project-based, multi-year engagement structure. Two primary customer segments are served: (1) major U.S. retailers (big-box and specialty) executing private-label store-brand programs, with finished products reaching 60,000+ retail locations worldwide; and (2) established and emerging wellness brands needing turnkey manufacturing, custom formulation, and scale-up from first order through full production. Revenue streams combine transaction-fee contract manufacturing with professional services for custom formulation and is generated across more than 80 countries. Growth has been driven primarily through eight acquisitions completed between 2010 and 2021, adding U.S. nutritional capacity, U.K. and German pharmaceutical and supplement operations, and a Canadian manufacturer.

Direct peers

• Best Formulations: Best Formulations is a U.S.-based contract manufacturer of vitamins, supplements, and nutraceuticals across multiple delivery formats. It is the most direct competitor to IVC's CDMO/private-label model for tablets, capsules, softgels, and powders.
• Robinson Pharma Inc. Robinson Pharma is a California-based supplements and softgel CDMO serving private-label and brand customers. It competes head-to-head with IVC for softgel and capsule contract manufacturing volumes, particularly for retail private label.
• Vitakem Nutrition Inc. Vitakem is a contract supplement manufacturer offering capsules, tablets, softgels, and powder blending with private label services. Overlaps directly with IVC's CDMO offerings and serves many of the same retailer and brand customers.
• NutraScience Labs: NutraScience Labs is a supplement contract manufacturer specializing in capsules, tablets, and powders with private label, custom formulation, and turnkey services. A close functional peer to IVC for emerging-brand turnkey manufacturing.
• VitaQuest International: VitaQuest is a U.S. contract development and manufacturing organization for dietary supplements and functional foods. Competes with IVC across custom formulation, manufacturing, and packaging services for supplement brands.
• Gemini Pharmaceuticals Inc. Gemini Pharmaceuticals is a nutraceutical and OTC CDMO producing tablets, capsules, and powders under cGMP for private label customers. Directly comparable to IVC's solid-dose contract manufacturing business.
• Tishcon Corporation: Tishcon is a Long Island-based contract manufacturer of vitamins and dietary supplements in tablet, capsule, and powder forms with private label services. Another functional peer to IVC's core CDMO operations.

Broad incumbents

• Pharmachem Laboratories (ADM): Pharmachem, now part of ADM, is a large-scale ingredient supplier and contract manufacturer serving the supplement, beverage, and personal care markets. Comparable to IVC in CDMO scale and category breadth but anchored in ingredients rather than finished-dosage services.
• Perrigo Company (Nutritionals): Perrigo is a major OTC and store-brand pharmaceutical and nutrition manufacturer with global operations. IVC previously acquired Perrigo's U.S. nutritional assets in 2016, making Perrigo a former-supplier-cum-overlap reference point for IVC's scale ambitions.
• Lonza Group (Capsules & Health Ingredients): Lonza is a global CDMO giant with a strong nutraceutical capsules and health ingredients franchise. It overlaps with IVC's capsule manufacturing and broader CDMO offering but operates at significantly larger scale and with broader modality coverage.
