Where and How Vitamins Are Made
Most vitamin brands don’t produce their own supplements. Instead, they work with a contract or private label manufacturer like Auri Nutra, who handles everything from formulation to packaging. Manufacturers like us take your formula idea, or help you develop one, and turn it into a compliant, finished product. This includes sourcing ingredients, performing lab testing, blending, encapsulating, bottling, and labeling.
The key? Finding a manufacturer who operates under FDA and cGMP (Current Good Manufacturing Practices)because in this industry, documentation, consistency, and Quality control isn’t optional, it’s required.
Why Vitamin Manufacturing Requires Precision, Compliance, and Science
Starting or expanding a vitamin brand isn’t as simple as mixing ingredients, it’s a process that blends biochemical expertise, strict regulatory standards, and advanced manufacturing technology. At Auri Nutra Inc., an FDA-registered and UL GMP- and USDA Organic-certified facility, we’ve mastered the art of producing high-quality vitamins and dietary supplements for global brands.
This guide walks you through how vitamins are truly manufactured, and what to look for when choosing a manufacturing partner that protects your brand’s quality and reputation.
1. Partner With a Certified, Transparent Manufacturer
When researching how to manufacture vitamins, always begin by verifying certifications and quality systems. A reputable partner should be able to show:
- FDA registration and UL or NSF GMP certification
- USDA Organic certification (for clean-label lines)
- In-house QA/QC team and third-party lab testing
- Complete traceability from raw materials to finished product
Auri Nutra proudly meets all of these standards, our facility undergoes continuous third-party audits to ensure compliance and consistency.
2. Ingredient Sourcing and Verification
High-quality vitamins start with verified, clean ingredients. Every raw material that enters our facility is accompanied by:
- Â A Certificate of Analysis (COA) verifying purity and potency
- Â Identity testing via FTIR or HPLC instrumentation
- Â Microbial and heavy metal screening
This prevents contamination and ensures that every ingredient is exactly what the label claims. Auri Nutra’s supply chain transparency also means every vendor we work with is audited for compliance with FDA and USDA Organic standards.
3. Custom Formulation and R&D Support
Whether you’re creating a basic multivitamin or an advanced blend with adaptogens and probiotics, R&D is critical. Our in-house formulation experts optimize every detail of your formula:
- Correct nutrient dosages for efficacy
- Bioavailability improvements
- Compatibility of active and inactive ingredients
- Overages to account for potency loss over time
Every formulation is backed by scientific data and tested for stability and uniformity, ensuring your product meets label claims through its entire shelf life.
4. Precision Manufacturing and Production
Once your formula is finalized, production begins under controlled cleanroom conditions. Our capabilities include:
- Encapsulation – vegetarian or gelatin capsules, delayed-release options
- Tablet compression – coated, chewable, effervescent, or sublingual
- Gummies and powders – pectin or gelatin-based gummies, flavored or unflavored blends Every batch is blended using validated homogenization protocols, ensuring even ingredient distribution. Equipment is calibrated and maintained according to GMP standards.
5. Quality Assurance and Testing
Throughout the process, our QA team performs continuous checks to confirm every specification is met.
Testing includes:
- In-process testing: weight, hardness, moisture, and uniformity checks
- Finished product testing: potency assays, disintegration, dissolution, and microbial testing
- Third-party verification
Only batches that meet all specifications are released, ensuring every capsule matches your label claims exactly.
6. Packaging, Labeling, and Compliance
After production, your vitamins move to packaging and labeling. We offer multiple packaging formats (bottles, blister packs, pouches) and ensure each label:
- Meets FDA and FTC regulations
- Avoids restricted medical claims (no “treat,” “cure,” or “prevent” language)
- Accurately reflects nutrient values, serving sizes, and supplement facts
Our regulatory specialists review every label to protect your brand from compliance risks.
