Independent Quality Unit (Quality Assurance / Quality Control)

An independent Quality Assurance / Quality Control (QA/QC) unit operates with full authority over product release decisions. This unit functions autonomously from manufacturing operations to maintain objectivity, prevent conflicts of interest, and ensure product integrity.

Regulatory Framework and Governance

Our program operates in compliance with Title 21 Code of Federal Regulations (21 CFR), including Part 111 (Dietary Supplement cGMP) and Part 117 (Food cGMP and Preventive Controls). It incorporates the Food Safety Modernization Act (FSMA) and is managed by Preventive Controls Qualified Individuals (PCQIs).

A fully integrated Food Safety Plan includes:

• Hazard analysis
• Preventive controls (process, sanitation, allergen, supply chain)
• Monitoring and verification programs
• Corrective action processes
• Recall readiness planning

Supplier Qualification and Risk Management

Suppliers are qualified using a risk-based approach considering ingredient type, country of origin, regulatory history, and potential for fraud.

Qualification activities include:

• Supplier audits and detailed questionnaires
• Specification review and alignment
• Sample qualification testing
• Ongoing performance scorecards

All incoming materials are required to meet defined specifications for identity, purity, strength, and composition. Reliance solely on Certificates of Analysis (COAs) is insufficient; confirmatory and identity testing is routinely performed.

Foreign suppliers are managed under the Foreign Supplier Verification Program (FSVP), where applicable.

Incoming Material Testing and Verification

All materials are received under quarantine with barcode traceability and undergo inspection and testing prior to release.

Analytical testing includes:

• Identity Testing
  • High Performance Thin Layer Chromatography (HPTLC)
  • Fourier Transform Infrared Spectroscopy (FTIR)
  • Near-Infrared Spectroscopy (NIR)
  • High Performance Liquid Chromatography (HPLC)
  • Ultra Performance Liquid Chromatography (UPLC)
• Contaminant Testing
  • Inductively Coupled Plasma Mass Spectrometry (ICP-MS) or Inductively Coupled Plasma Optical Emission Spectroscopy (ICP-OES) for heavy metals in accordance with United States Pharmacopeia (USP) <2232>
  • Residual solvents per USP <467> using Gas Chromatography Headspace Flame Ionization Detection (GC-HS-FID) or Gas Chromatography Mass Spectrometry (GC-MS)
  • Pesticides by Liquid Chromatography Tandem Mass Spectrometry (LC-MS/MS) or Gas Chromatography Tandem Mass Spectrometry (GC-MS/MS)
  • Mycotoxins for high-risk materials
• Microbiological Testing
  • Total Aerobic Plate Count (TAPC)
  • Total Yeast and Mold Count (TYMC)
  • Pathogens such as Salmonella, Escherichia coli, Staphylococcus aureus, Pseudomonas aeruginosa based on risk
• Quality and Functional Testing
  • Moisture analysis (Karl Fischer titration)
  • Oxidation markers for oils
  • Particle size verification

In addition to identity and contaminant testing, selected raw materials undergo Strength and Potency Verification to confirm quantitative composition and label claim alignment where applicable.

• Performed using validated methods such as:
  • High Performance Liquid Chromatography (HPLC)
  • Ultra Performance Liquid Chromatography (UPLC)
  • Inductively Coupled Plasma Mass Spectrometry (ICP-MS), where appropriate
• Testing is conducted on a rotational, risk-based, and challenge-driven basis, considering:
  • Ingredient criticality (e.g., actives vs. excipients)
  • Supplier qualification status and historical performance
  • Variability risk (natural materials, complex blends)
  • Regulatory or specification sensitivity
• This approach provides an additional layer of verification beyond Certificates of Analysis (COAs), supporting:
  • Ongoing supplier verification
  • Detection of variability or drift over time
  • Increased confidence in raw material consistency

Facilities, Utilities, and Environmental Controls

Manufacturing operations occur in controlled environments with:

• Segregated processing zones to manage allergen risk
• Validated/verified sanitation processes and environmental monitoring
• Controlled water systems using Reverse Osmosis / Deionization (RO/DI) loops
• High Efficiency Particulate Air (HEPA) filtration where required
• Environmental controls for temperature and humidity

All critical instruments and systems undergo routine calibration, maintenance, and qualification.

In-Process Controls

Each dosage form is monitored with defined in-process controls to ensure consistency and compliance:

• Blend uniformity verified using Relative Standard Deviation (RSD)
• Metal detection and foreign material controls
• Fill weight and net content verification

Finished Product Testing and Release

Finished products are evaluated prior to release, including:

• Potency verification using HPLC, UPLC, or ICP techniques
• Microbiological testing (TAPC, yeast, mold, pathogens)
• Contaminant testing including heavy metals and allergens
• Physical evaluation (appearance, odor, taste, disintegration)

Final batch release is completed only after full review of the Batch Production Record (BPR), any deviations and Corrective and Preventive Actions (CAPA), and all analytical test results. A final Certificate of Analysis (COA) is issued.

Where applicable, analytical testing is performed by qualified laboratories operating under ISO/IEC 17025-accredited quality systems. These laboratories maintain validated analytical methods, calibrated instrumentation, documented data integrity controls, and established proficiency standards to support the accuracy, reliability, and traceability of test results. Utilization of ISO/IEC 17025-accredited laboratories provides additional assurance that analytical activities are conducted in accordance with internationally recognized laboratory competence requirements.

Post-Market Surveillance and Continuous Improvement

A comprehensive complaint handling system classifies and investigates all feedback, including potential adverse events. Trends are monitored to identify systemic risks.

Recall readiness is maintained through documented plans and mock recall exercises to ensure rapid and effective response if required.

Laboratory and Manufacturing Capabilities

Our analytical and manufacturing capabilities include:

• Inductively Coupled Plasma Mass Spectrometry (ICP-MS)
• High and Ultra High Performance Liquid Chromatography (HPLC/UHPLC)
• Liquid and Gas Chromatography Mass Spectrometry (LC-MS/MS, GC-MS/MS)
• Rapid microbiological testing methods, including quantitative Polymerase Chain Reaction (qPCR)
• Laboratory Information Management Systems (LIMS) for data integrity and traceability

Digital systems support electronic Batch Production Records (eBPR), Master Manufacturing Records (MMR), and fully integrated deviation and change control processes.

People and Expertise

Dedicated personnel support the quality system, including:

• Quality Unit (QA/QC)
• Analytical Chemists
• Microbiologists
• Supplier Quality Management
• Validation and Metrology specialists
• Regulatory and Labeling specialists

Each role contributes to maintaining a robust, compliant, and continuously improving quality system aligned with regulatory expectations and industry best practices.
