Manufacturing Process
Our Manufacturing Process
Every Nutri-Leaf supplement is manufactured at the BHI Biohealth International GmbH facility in Münchberg, Germany. From raw material selection to the sealed bottle you receive, each step follows strict protocols designed to ensure safety, potency, and purity. Here is an overview of how our supplements are made.
1. Raw Material Sourcing and Testing
Every ingredient begins its journey with rigorous supplier qualification. We source raw materials only from reputable, audited suppliers who meet our quality criteria. Upon arrival at our facility, each batch of raw material undergoes comprehensive testing including:
- Identity verification — confirming the material is exactly what was ordered (using techniques such as FTIR, HPLC, or microscopic analysis depending on the ingredient).
- Purity analysis — testing for heavy metals (lead, cadmium, mercury, arsenic), microbiological contaminants, and residual solvents.
- Potency assay — measuring the active ingredient concentration to ensure it meets specifications.
Only materials that pass all tests are released for production. Non-conforming materials are quarantined and returned to the supplier.
2. Formulation and Blending
Our formulations are developed based on scientific evidence and regulatory compliance. Each batch is produced according to a master manufacturing record that specifies exact quantities, mixing times, and process parameters. The blending process uses state-of-the-art equipment to ensure homogeneity — every capsule in the batch contains the same consistent amount of each active ingredient. We validate blend uniformity through in-process sampling and testing.
3. Encapsulation
Nutri-Leaf capsules use plant-based HPMC (hydroxypropyl methylcellulose) shells derived from cellulose. Unlike gelatine capsules (which are animal-derived), HPMC capsules offer:
- Plant-based origin — suitable for vegetarians and vegans.
- Low moisture content — better stability for moisture-sensitive ingredients.
- No cross-linking risk — consistent dissolution and bioavailability.
The encapsulation process is fully automated, with continuous monitoring of fill weight, capsule integrity, and sealing quality. Capsules that do not meet specifications are automatically rejected.
4. Quality Control — Every Batch Tested
Once encapsulated, every production batch undergoes a comprehensive quality control programme:
- Identity testing — confirming active ingredients are present.
- Potency testing — verifying the amount of each active ingredient matches the label claim.
- Microbiological testing — checking for bacteria, yeast, mould, and pathogens.
- Heavy metals analysis — ensuring levels are within safe limits.
- Disintegration testing — confirming capsules release their contents properly.
- Uniformity of mass — verifying consistent capsule weight across the batch.
A batch is released for packaging only after all tests meet specifications. If any test result falls outside specification, the entire batch is quarantined for investigation.
5. Packaging and Labelling
Our packaging process takes place in a controlled environment. Bottles are filled, sealed, and labelled using automated equipment. Each label includes the product name, batch number, expiry date, ingredient list, nutritional information, recommended use, storage conditions, and all legally required notices and warnings. The batch number links the finished product back to the complete production and testing records.
6. Batch Traceability
Every single capsule is traceable. Our batch numbering system links the finished product back through the entire production chain — to the encapsulation run, the blending batch, and ultimately to each specific raw material lot used. This level of traceability, required under FSSC 22000, means we can investigate any quality concern thoroughly and precisely. This is transparency you can count on.
7. FSSC 22000 Certified Environment
The entire manufacturing process takes place in an FSSC 22000 certified facility (Certificate No. FSS-00263/0). This certification, audited annually by Quality Austria, means our facility meets the most stringent international food safety standards. It is your guarantee that every step — from raw material arrival to finished product dispatch — follows documented, validated, and independently verified procedures.
Made in Germany
We are proud to manufacture in Germany. Our facility in Münchberg, Bavaria, benefits from Germany's engineering expertise, rigorous regulatory environment, and skilled workforce. When you choose Nutri-Leaf, you are choosing German quality that you can trace from Münchberg to your home.
