If you’re evaluating a nutraceutical contract manufacturer, understanding the manufacturing process tells you whether they actually meet WHO-GMP standards or just claim to. This guide walks through the full process used in our nutraceutical manufacturing facility in Nalagarh — from incoming raw materials to dispatched finished goods.
Stage 1: Formulation Development
Every product starts with a formulation document specifying active ingredients (APIs) with potency, excipients, target dosage form, pack size, stability targets (24 months minimum), and regulatory category. Brand owners can either select from 95+ ready formulations or commission custom R&D. Custom development typically takes 12–24 weeks including stability validation.
Stage 2: Raw Material Procurement
Every raw material is sourced from approved vendors with valid Drug Master Files. On arrival, each batch is quarantined under “UNDER TEST” labels. QC pulls samples, performs identity testing via FTIR or HPLC, assay testing for potency, microbial limit testing, and heavy metal testing. Materials are released only after QC sign-off.
Stage 3: Dispensing
Approved raw materials are dispensed in a Grade D cleanroom with controlled humidity and temperature. Each batch has a unique Batch Manufacturing Record (BMR), is dispensed against the BMR by trained operators, with double-verification on weighing.
Stage 4: Granulation
For tablets and structured powders, ingredients go through granulation. Dry granulation (slugging or roller compaction) for moisture-sensitive APIs. Wet granulation (high-shear mixers or fluid bed granulators) with binder solutions, followed by drying. In-process checks: granule size distribution, loss on drying, bulk density.
Stage 5: Encapsulation
Capsule machines fill empty hard gelatin or HPMC capsules with the formulated blend. Capacity at our facility: 5 lakh capsules per day. In-process checks every 30 minutes: weight variation, capsule lock integrity, visual defects, disintegration time.
Stage 6: Tablet Compression
Tablet presses compress the granulated blend into tablets at speeds of 50,000–200,000 tablets per hour. Critical parameters: hardness (8–18 kP), friability (NMT 1.0%), disintegration time, weight uniformity, thickness.
Stage 7: Coating
Tablets requiring coating go through film coating (taste-masking, identification, moisture protection), sugar coating, or enteric coating (for delayed release in intestine).
Stage 8: Softgel Encapsulation
Softgels are formed on rotary die machines that simultaneously form the gelatin shell and inject the oil/liquid fill. Used for omega-3, vitamin D3, vitamin E, evening primrose, krill oil. Critical control: shell thickness, fill weight, leak test, drying time.
Stage 9: Powder Blending and Filling
For protein powders and bulk powders, ingredients are blended in V-blenders or ribbon blenders. Blend uniformity is verified by sampling at multiple points. Filled into single-serve sachets, jars (30g–2kg), or bulk containers.
Stage 10: Syrup and Suspension Manufacturing
Liquid orals are manufactured in stainless steel mixing vessels with heating/cooling jackets, high-shear mixers, pH and viscosity control, 0.45 micron filtration before filling. Filled into PET or glass bottles, capped, induction-sealed.
Stage 11: In-Process Quality Control
Throughout every stage, QC checks happen at fixed intervals. The plant maintains HPLC for assay and impurities, UV-Vis spectrophotometer, dissolution apparatus, disintegration apparatus, friability tester, hardness tester, Karl Fischer for moisture, and microbiology lab with laminar flow hoods.
Stage 12: Packaging
Primary packaging (blister, alu-alu, bottle, sachet) in controlled environment. Secondary packaging (cartons, leaflets, labels) with serialization for export markets. Tertiary packaging (shipper cartons, palletization) for transit. Coding lines apply batch number, mfg date, expiry date with vision verification.
Stage 13: Final Quality Release
Before any batch ships, QC issues a Certificate of Analysis (COA) covering identity and assay of actives, physical parameters, disintegration / dissolution, microbial limits, heavy metals, stability indicators. Quality Assurance (QA) reviews the complete BMR, COA, and deviation reports before approval.
Stage 14: Storage and Dispatch
Released finished goods are stored in temperature-controlled warehouses (15–25°C, RH 60% max). Dispatch happens with COA copy, invoice with batch number, e-way bill (GST compliance), cold-chain logistics for sensitive formulations.
Stage 15: Stability Monitoring
Even after dispatch, samples from every batch go into the stability chamber. Data is collected at 0, 3, 6, 9, 12, 18, 24 months at 25°C/60% RH (long-term), 30°C/65% RH (intermediate), 40°C/75% RH (accelerated).
Documentation
Every step generates documentation: BMR, BPR, equipment usage log, cleaning log, calibration records, training records, deviation reports, change controls, CAPA. WHO-GMP audits review these records going back several years.
What This Means for Brand Owners
When you partner with a nutraceutical contract manufacturer, you’re not just paying for production — you’re paying for the entire QMS that ensures your product is safe, consistent, and compliant. Cheaper manufacturers cut corners somewhere in this chain. The cost shows up later as recalls, bad reviews, or regulatory action.
Biofril Healthcare’s plant in Nalagarh runs the full process above under WHO-GMP, ISO 9001:2015, FSSAI, and HACCP compliance. Every batch is traceable from incoming raw material to final dispatch.
