Record.

Gantol operates a fixed production methodology. Each step from initial ingredient procurement through to batch dispatch follows a documented sequence. No batch enters the distribution chain without completing all verification stages in the process log. The methodology described here represents the current revision — Revision 05-C — as maintained at the Jakarta facility.

Seven steps. Each one documented before the next begins.

01
Ingredient Specification Review

Before any production cycle, the ingredient specification sheet for each active compound is reviewed against the current formulation file. Quantities, elemental profile targets, and acceptable tolerance ranges are confirmed. If any supplier has issued a revised certificate of composition since the previous batch, the specification sheet is updated and the revision logged under the applicable lot number prefix.

02
Incoming Ingredient Receipt

Active ingredients arrive at the Jakarta facility accompanied by a certificate of composition from the originating supplier. Each delivery is logged against the purchase order with the arrival date, lot code, and supplier identifier. Ingredient quantities are weighed against the declared amounts. Discrepancies above the documented tolerance threshold are flagged and the affected consignment is quarantined pending resolution with the supplier.

03
Pre-Blend Sampling

A sample from each incoming ingredient lot is retained and labelled with the lot code prior to blending. These samples are archived in the facility's ingredient reference library and matched to the corresponding batch during independent laboratory review. The pre-blend samples allow for retrospective ingredient-level analysis if a post-dispatch quality query arises.

04
Controlled Blending

Ingredient blending is performed in a controlled workspace operating under food-grade processing standards. Mixing sequence and duration are documented in the batch record and followed without deviation. Blend homogeneity is assessed by in-process weight checking at three intervals during the blending cycle. The completed blend is sealed and assigned a unique batch identification code before encapsulation.

05
Encapsulation and Filling

Capsule shell material is sourced separately and subject to its own incoming receipt log. Fill weight is monitored throughout the encapsulation run using periodic sampling. Capsules failing the fill-weight specification are removed from the run and logged as non-conforming units. Final unit count is reconciled against the blend quantity as a completeness check before the batch is sealed for testing.

06
Independent Batch Verification

A sealed sample from each completed batch is submitted to an independent laboratory for elemental profile analysis and labelling accuracy review. The laboratory issues a certificate of analysis referencing the batch code. Results are reviewed against the Gantol compositional specification. Batches where the certificate of analysis shows deviation beyond the stated tolerance range are not dispatched. The laboratory is rotated periodically to prevent single-provider dependency.

07
Dispatch Authorisation and Archive Entry

Dispatch authorisation is issued only after the certificate of analysis has been received, reviewed, and filed. The batch record — comprising the specification sheet, incoming receipt log, pre-blend sample reference, in-process weight records, encapsulation log, and certificate of analysis — is compiled into the Gantol lot archive. The archive entry is assigned the batch code and the dispatch date. Each unit in the dispatched batch carries the batch code on its label for consumer traceability.

Six standards applied consistently across every production run.

Independent Testing

Every batch is submitted to an independent laboratory before dispatch. Testing covers elemental composition, fill-weight accuracy, and labelling compliance. No batch is released without a current certificate of analysis on file.

Chain-of-Custody Records

Each active ingredient is traceable from its originating supplier lot through to the dispatched batch. The chain-of-custody record is maintained in the facility archive and referenced in the batch log against the unique lot code.

Lot Archive Integrity

Batch records are archived in sequence and never modified after dispatch authorisation. If a correction is required, a revision note is appended under a new revision number and dated. The original entry remains in the archive unchanged.

Fixed Compositional Standard

Ingredient ratios within the Gantol formulation are held to a fixed compositional standard that does not change between production runs. Seasonal or cost-driven substitutions are not permitted. Any formula revision requires a new version entry and a full re-verification cycle.

Cold-Chain Compliance

Temperature-sensitive ingredient shipments are handled under documented cold-chain conditions from supplier dispatch to facility receipt. Delivery temperature logs are retained with the incoming receipt record for each affected ingredient lot.

Regulatory Registration

Gantol products are nutritional food-supplements registered with the applicable local regulatory authority under food-supplement classification. Products meet compositional and labelling requirements for nutritional supplement categories.

Three documented suppliers. All reviewed annually.

Active ingredient suppliers are reviewed on an annual cycle. The review covers chain-of-custody documentation, processing facility standards, and certificate-of-composition consistency across the preceding year's deliveries. A supplier whose records are incomplete or inconsistent is placed on hold pending resolution.

Certificate of Analysis — Independent Laboratory

Active ingredients are sourced from documented suppliers, with each batch accompanied by a certificate of composition. Sourcing prioritises suppliers whose facilities maintain food-grade processing standards.

Ingredient profiles in Gantol supplements are selected based on published nutritional research and undergo independent batch verification for quality and labelling accuracy. The research basis for each ingredient's inclusion in the formulation is documented in the product file, which is maintained at the Jakarta facility and updated with each formula revision.

We recommend speaking with a qualified wellness or nutrition professional before introducing any supplement to your daily routine, particularly if you have specific dietary requirements.

Frequently asked methodology questions.

Every production batch is submitted for independent laboratory analysis before dispatch. There are no exemptions — a batch without a current certificate of analysis on file is not authorised for dispatch regardless of the production schedule.
The batch code printed on your Gantol product label corresponds to the lot archive entry. Certificates of analysis are available on request by contacting Gantol directly with your batch code. We aim to respond to certificate requests within five business days.
No. The Gantol formulation operates on a fixed compositional standard. Ingredient quantities and ratios are held constant across all production runs. Any revision to the formula — whether in ingredient selection or quantity — requires a new version designation, a full supplier documentation update, and a complete independent verification cycle before the revised product is dispatched.
Gantol uses independent third-party laboratories for batch verification. The laboratory is rotated periodically as a standard practice to prevent reliance on a single testing provider. The name of the laboratory is recorded in the relevant batch archive entry and is available alongside the certificate of analysis on request.
Supplier selection requires a minimum of three completed deliveries with consistent chain-of-custody documentation before a supplier is formally approved. Approved suppliers are reviewed annually against a checklist of documentation requirements. Suppliers failing the annual review are suspended from the active supplier list until the documentation gaps are resolved.
Food-grade processing standards require that the production environment, equipment, and handling procedures are appropriate for the production of food and nutritional supplement products. This includes workspace cleanliness protocols, equipment sanitation schedules, and controlled-access production areas. Gantol's facility and those of its active suppliers operate under these conditions and maintain documentation of compliance.
