Step 1: Formula review and batch authorization
On our production floor, the work between a submitted formula and finished goods is mostly controlled handoffs, not a single manufacturing event. I am Rohan Mehta, and at Leumas I see founders most often underestimate the time needed to close specification gaps, confirm materials, and prepare a usable batch record. The workflow does not mean a manufacturer simply presses start. It means turning a formula into an authorized, schedulable batch.
Here is the Leumas workflow from spec receipt to shipment. The same stages apply to a 500-unit pilot and a 5,000-unit production run, although individual stage timing can differ.
We first check the formula specification for completeness and manufacturability. This is not reformulation. It is a practical review against what our floor can weigh, blend, fill, inspect, and document. We look at dosage form, ingredient quantities, process requirements, packaging scope, and the information needed for the batch record.
When the formula fits our dosage-form capabilities and the information is complete, we issue batch authorization and begin procurement. If something is missing, such as a fill-weight tolerance, we send the question back before purchasing starts. Resolving that detail early is faster than discovering it during setup.
Step 2: Raw material procurement and incoming quality check
After authorization, we purchase ingredients that are not already in stock. Timing depends on the material. Standard vitamins and minerals may be available in 2-5 business days, while specialty ingredients can require 14 days or more. A supplier confirmation may arrive within 24-48 hours, but that confirmation is not the same as material receipt.
Every delivered material receives an incoming quality check before storage. We inspect the material and packaging, compare the supplier CoA with the purchase order, and record lot and quantity details. Any mismatch is held for review rather than released to the floor.
Procurement is usually the longest single stage when a formula includes specialty ingredients. A launch tied to a fixed date should allow for it. Submitting a specification 10-12 weeks before the target gives the team room to source, review, and resolve issues without compressing later work.
Step 3: Batch scheduling and floor planning
After all materials pass incoming QC, the batch enters the production queue. Our AI-assisted scheduling system reviews the queue, equipment needs, cleaning requirements, and promised timing to suggest an order for the runs. It helps us see conflicts before a batch reaches the floor, but the production team remains responsible for the schedule.
The resulting plan assigns each batch a day and floor slot. It also identifies the cleaning validation step before the run and the equipment state required at startup. We review the suggested sequence against actual floor conditions and adjust it when a material, person, or machine is not ready.
For a standard pilot, queue wait plus scheduling confirmation adds 3-5 business days after all materials clear incoming QC.
Step 4: Compounding and blending
Manufacturing begins with compounding. We weigh each raw material against the formula, compare the weights with the batch record, and stage the materials for blending. For a capsule formula with 5 ingredients, this is where a small weighing discrepancy is caught before it can affect the full blend.
Blending combines the weighed materials into a uniform powder. The blend time and equipment settings depend on the ingredients. One blend may tumble for 20 minutes, while another needs a defined sequence, including a 15-minute preblend, before the remaining materials are added. The operator records the settings and observations in the batch record.
Step 5: Filling, encapsulation, and in-process checks
The finished blend moves to the filling station. For capsules, we load it into the automated capsule filler, set the fill-weight parameters, and run the startup checks. We confirm the setup before continuing, then take timed samples during the run to verify that the process remains within the approved limits.
Powder filled into tubs or sachets uses a different filling line, but the in-process control structure is similar: timed pulls, weight checks, and documentation of the results. The equipment changes, while the need to monitor the run does not.
After filling, units pass through tamper-evident sealing, labeling when artwork and labeling are in scope, and visual inspection. Units with seal failure, label problems, or visible defects are separated for disposition rather than included in the finished quantity.
Step 6: Final analytical testing and certificate of analysis
Finished-product testing is the final manufacturing step before release. We pull a sample set according to the sampling plan and submit it for the test panel specified in the batch protocol. Standard testing may include identity, potency, and the other checks defined for that batch.
Test turnaround has the most schedule variability. In-house tests usually finish in 3-5 days. Third-party heavy-metal testing or specialized potency assays may take 7-10 business days. The analytical window should be included in the launch plan rather than treated as time after manufacturing.
Step 7: Documentation assembly and shipment
After testing passes, we assemble the documentation package: Certificate of Analysis, batch record digest, ingredient traceability report, and deviation log when applicable. We send the package to the brand at the same time the finished goods are prepared for shipment.
For a standard capsule-fill pilot, the full period from spec submission to shipment is typically 6-8 weeks. A 5,000-unit production run is typically 4-6 weeks because many first-run validation activities are already documented. That range still depends on material availability, testing, and how quickly open questions are resolved.
