The Dralven methodology is an eight-stage sequence from research and sourcing through to archival lot registration. Each stage produces a documented output that becomes part of the permanent record for that batch.
Each new formula begins with a gap analysis against published reference intake data for adult males in the Central European dietary context. National food consumption surveys and peer-reviewed bioavailability literature are the primary sources. The analysis produces a ranked list of micronutrient shortfalls and their documented prevalence rates.
The formulation specification determines active ingredient selection, serving size, and the ratio of each component per daily measure. Ingredient forms are selected for established bioavailability — bisglycinate chelates for minerals, methylated forms for B vitamins, standardised extracts for botanical ingredients.
Candidate suppliers are evaluated on four criteria: documented processing facility standards, origin traceability to named region, willingness to provide pre-contract lot analysis, and consistency of elemental profile across three consecutive production runs. Suppliers that do not pass all four criteria are not contracted.
On receipt of each ingredient consignment, the lot code, certificate of origin, and supplier-provided analysis are logged against the formula specification. An intake record is opened in the archive. No consignment enters production without a completed intake record cross-referenced to the supplier's own documentation.
Encapsulation takes place at a food-supplement production facility operating under documented food-grade standards. All Dralven formulas use HPMC (hydroxypropyl methylcellulose) plant-derived capsule shells. Batch size and production run date are assigned a production lot number at encapsulation start.
A sample from each production lot is submitted to an independent laboratory for elemental concentration analysis. The analysis methodology is ICP-OES (inductively coupled plasma optical emission spectrometry) for mineral elements and HPLC for organic compounds including vitamins and botanical marker substances. Results are compared against the formula specification before release.
On receipt of the independent analysis results, a label accuracy confirmation is performed. The declared ingredient quantities on the product label are cross-referenced against the analysis results. Where results fall within the ±15% tolerance accepted by food-supplement classification standards, the lot is cleared for release. Results outside tolerance result in lot hold pending investigation.
On clearance, the complete lot record is finalised in the Dralven archive: intake documentation, production date and batch size, independent analysis certificate, label accuracy confirmation, and the revision-numbered protocol version in use at time of production. The archive is maintained indefinitely and is accessible on request for any lot in the current range.
The Dralven supplier network spans Poland, Czech Republic, Germany, India, Sri Lanka, Brazil, and Spain. Supplier relationships are governed by individual supply agreements that include mandatory lot analysis provisions and origin documentation requirements.
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.
Supplier performance is reviewed annually. Any supplier failing to provide required documentation for two consecutive lots is placed on hold pending a review of the supply agreement.
Ingredient profiles in Dralven supplements are selected based on published nutritional research and undergo independent batch verification for quality and labelling accuracy. The methodology does not claim outcomes beyond what the food-supplement category permits.
The purpose of the eight-stage protocol is to reduce the distance between the published research informing ingredient selection and the verified composition of the finished product reaching the end user. Documentation integrity is the mechanism by which that distance is managed.
Dralven 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.
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.
