These brands rarely manufacture their own products. Instead, they partner with contract manufacturers who handle production while the brand manages marketing, distribution, and customer relationships.
Vitamin Suppliers USA: The Raw Material Network
Behind every finished vitamin product sits a complex supply chain of raw material suppliers providing active pharmaceutical ingredients (APIs) and excipients. These vitamin suppliers USA form the foundation of the manufacturing process.
Global Dominance: DSM and BASF
Global manufacturers like DSM and BASF dominate raw material production for vitamins worldwide. These European chemical giants produce the bulk of vitamin active ingredients used by supplement manufacturers globally.
DSM and BASF, the world’s largest sellers of vitamins, produce or plan to produce bulk vitamins in China due to low-cost competition. This strategic shift reflects the economic realities of vitamin production where Chinese manufacturers have cost advantages in energy, labor, and environmental compliance.
DSM (now DSM-Firmenich after a 2023 merger) operates production facilities across Europe, China, and other locations globally. The company produces essential nutrients including synthetic vitamins, carotenoids, and specialty nutritional ingredients. DSM Nutritional Products produces essential nutrients such as synthetic vitamins and carotenoids for use in dietary supplements, fortified foods, and animal nutrition.
BASF operates through its Nutrition & Care segment, offering comprehensive vitamin portfolios for human nutrition, animal nutrition, and pharmaceutical applications. Both companies invest heavily in research and development to improve production efficiency and develop new vitamin forms with enhanced bioavailability.
The China Factor
Manufacturers withdrew from the vitamin market as Dutch DSM, German BASF and Lonza shut down their vitamin C and vitamin E production facilities in the United States. These closures shifted global vitamin production overwhelmingly toward Asia, particularly China.
In the past 10 years, low-cost vitamins from China have wrecked the once-thriving European vitamin industry, and while vitamins are still made in Europe and North America, more and more nutrition supplements are made in China. The shift occurred due to multiple cost advantages Chinese producers enjoy.
China is particularly strong in vitamins made through fermentation, an energy-intensive activity, and many Chinese producers get their electricity at subsidized rates. Additionally, historically less stringent environmental regulations reduced waste disposal costs, though this has changed significantly in recent years as Chinese authorities have tightened environmental standards.
Major Chinese vitamin producers include:
- Zhejiang NHU Co. Ltd.
- CSPC Pharmaceutical Group
- Zhejiang Medicine Co. Ltd.
- Xiamen Jindawei Vitamin Co. Ltd.
- Northeast Pharmaceutical Group (NCPG)
Around 2005, the market saw a shift when DSM closed its US bulk ascorbic acid plant in Belvidere, New Jersey, making DSM’s plant in Dalry, Scotland the only remaining vitamin C producer outside of Asia. This consolidation exemplifies how vitamin production has migrated to lower-cost regions.
Indian Suppliers
India has emerged as a significant player in vitamin and pharmaceutical ingredient production. Key players in the vitamin D market include DSM (Netherlands), Fermenta Biotech Ltd. (India), Dishman Group (India), and Zhejiang Medicine Co. Ltd (China), showing India’s growing importance in specific vitamin segments.
India is the preferred low-cost/best-cost country for sourcing vitamins and dietary supplements, with a growing number of international companies entering the Indian market leading to increased industry competition and innovation. Indian manufacturers offer competitive pricing while maintaining quality standards that meet international regulatory requirements.
Indian companies like Fermenta Biotech, Jubilant Organosys, and others specialize in fermentation-derived vitamins and active pharmaceutical ingredients. These companies serve both domestic and export markets, supplying raw materials to supplement manufacturers worldwide.
U.S.-Based Suppliers and Distributors
Several U.S.-based companies function as suppliers and distributors of vitamin raw materials, though most source their ingredients from overseas manufacturers:
Lipond International – Established in 1996, Lipond International has grown to be one of the leading raw material suppliers, offering natural plant extracts, vitamins, amino acids, and pharmaceutical intermediates. The company maintains warehouses on both coasts for rapid delivery.
NatureGen – Headquartered in San Diego with manufacturing facilities in China, NatureGen supplies botanical and non-botanical ingredients to North American nutraceutical manufacturers.

These distributors provide crucial services beyond simply supplying ingredients. They offer technical support, regulatory documentation, quality assurance, and logistics management that helps manufacturers navigate the complexities of international ingredient sourcing.
The Vitamin Manufacturing Process: From Raw Materials to Finished Products
Understanding how vitamin manufacturers in USA transform raw materials into finished products reveals the complexity and precision required to produce safe, effective supplements.
Formulation Development
Prior to the actual vitamin manufacturing process, it’s necessary to devise the right formula for the supplements, with manufacturers doing research and development to come up with the correct formulation of ingredients. Each brand has its own particular formula even when selling similar products.
Formulation scientists consider multiple factors including:
- Active ingredient dosages based on scientific research
- Bioavailability and absorption rates
- Interactions between different vitamins and minerals
- Stability throughout the product’s shelf life
- Manufacturing feasibility with available equipment
- Regulatory compliance with FDA and USP standards
- Cost targets for the finished product
A vitamin manufacturer typically creates pilot batches during formulation development, testing and adjusting the formula until achieving the desired characteristics. This development phase can take weeks or months depending on formulation complexity.
Raw Material Procurement and Testing
Ordering and receiving raw materials is the longest part of the manufacturing process and can take 2-8 weeks, with timing depending on location and immediacy of availability. This timeline explains why manufacturers maintain substantial ingredient inventories to avoid production delays.
Although raw material suppliers provide a certificate of analysis (COA), the contract manufacturer should not rely on the COA alone, and once raw materials arrive at the facility, they must be quarantined and tested before release into inventory. This “trust but verify” approach ensures quality control.
Testing includes:
- Identity verification using established methodologies
- Potency testing to confirm ingredient concentration
- Microbiological testing for bacterial contamination
- Heavy metal testing for lead, arsenic, mercury, and cadmium
- Pesticide residue screening when applicable
- Physical testing of particle size and flow properties
The entire process of raw material testing may take anywhere from 1-2 weeks, adding to the total production timeline. Only after passing all tests does the ingredient get released from quarantine for use in manufacturing.
Blending and Mixing
All raw materials that comprise a given dietary supplement are mixed in a large-scale commercial blender, and during this process, the raw materials must be completely and uniformly mixed to ensure an even distribution of each specified vitamin, mineral, and herb throughout the entire batch. Uniform mixing ensures every capsule or tablet contains the same amount of each ingredient.
Vitamin tablets or capsules may contain additives that help the manufacturing process, with fillers such as Microcrystalline Cellulose Powder, Lactase powder, Calcium powder, or Maltodextrin used for bulking, while Magnesium stearate powder serves as a lubricant and silicon dioxide powder acts as a flow agent. These excipients aren’t active ingredients but they’re essential for manufacturing efficiency.
After blending, laboratory technicians take samples to verify mix uniformity. They test for proper distribution of key ingredients throughout the batch. Only after confirming uniform distribution does production proceed to the next stage.
Dosage Form Production
Manufacturers produce vitamins in multiple delivery formats:
Tablets – Compressed powder blends formed under high pressure. Tablet presses can produce thousands of tablets per hour with consistent weight and hardness specifications.
Capsules – Either hard gelatin capsules or vegetarian alternatives filled with powdered ingredients. Automated capsule filling equipment ensures precise fill weights.
Softgels – Gelatin shells containing oil-based or liquid ingredients. Softgel production requires specialized equipment and controlled temperature/humidity conditions.
Gummies – Increasingly popular format requiring different manufacturing processes including cooking, molding, and coating operations.
Powders – Blended ingredients packaged directly without compression or encapsulation. Powders offer dosing flexibility but require careful mixing to prevent separation.
Liquids – Vitamin solutions requiring specialized mixing equipment, filtration, and preservative systems to maintain stability.
