Formulation Process.
There is a particular quietness to good process — it does not announce itself. It simply produces the same reliable result, batch after batch, without drama. What follows is a documented account of how Tamrelo builds its formulations and how it intends to keep doing so.
Selection grounded in published nutritional research, not market trends or marketing conventions.
Every supplier relationship is documented. No anonymous ingredient sourcing. Each batch has a traceable origin.
Third-party batch verification confirms ingredient concentration and label accuracy before any release.
Formulation briefs are reviewed each year against current EFSA guidance and emerging nutritional literature.
From Research Literature to Finished Formulation.
Nutritional Gap Assessment
Each formulation begins with a structured review of the nutritional gaps most prevalent in the demographic group it is intended to serve. For men's daily supplementation, this review draws on population-level dietary analysis, published intake surveys, and European food safety guidance.
The assessment produces a priority list of nutrients — not a wishlist, but a ranked document noting where intake gaps are most consistently documented. This list becomes the foundation of the formulation brief.
Ingredient Selection Brief
From the priority list, a selection brief is drafted. This document specifies which nutrients are under consideration, the nutrient form (e.g., Magnesium Bisglycinate vs. Magnesium Oxide), the target serving level relative to NRVs, and the published research basis for each decision.
The selection brief is reviewed against the Tamrelo stop-list — a maintained record of ingredient categories that the range does not use — before proceeding to sourcing.
Supplier Qualification
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.
A supplier qualification record is maintained for each approved source. This record includes the supplier's facility documentation, the certificate scope, and the date of the most recent batch audit. Suppliers are reviewed annually.
Formulation Drafting
With approved ingredients and suppliers confirmed, a production formulation is drafted. This specifies exact ingredient ratios, serving weight, daily intake volume, and packaging requirements. The draft is cross-checked against the original selection brief to confirm no specification has drifted during the sourcing stage.
Interactions between ingredients are reviewed at this stage. Where two nutrients are known to compete for absorption at high concentrations, serving timing guidance is added to the composition notes.
Pilot Batch Production
A pilot batch is produced at reduced volume before any full production run. The pilot batch is assessed against the formulation specification for homogeneity, particle distribution, and physical stability. The assessment is documented and retained.
If the pilot batch does not meet specification, the formulation is returned to the drafting stage and the discrepancy is recorded. No composition enters full production without a successful pilot batch assessment.
Independent Batch Verification
Ingredient profiles in Tamrelo supplements are selected based on published nutritional research and undergo independent batch verification for quality and labelling accuracy. A third-party accredited facility conducts elemental analysis and active content verification on each production batch.
Verification reports are retained alongside the corresponding production batch documentation. The batch is not released to distribution until the verification report is received and reviewed. Reports showing concentration outside the acceptable variance band trigger a production hold.
Annual Formulation Review
Each formulation in the Tamrelo range is reviewed annually against current EFSA guidance documentation and available nutritional literature. The review assesses whether the formulation remains aligned with current understanding of serving levels, ingredient forms, and population intake data.
Where the review identifies an improvement to a formulation, the change is documented, the formulation brief is updated, and the new version enters the supplier qualification and pilot batch stages before production resumes. Version history is maintained for each composition.
Where the Ingredients Come From.
The Tamrelo sourcing map reflects a deliberate set of decisions about what kinds of supplier relationships are worth maintaining. The map is not static — it is reviewed annually as part of the formulation review cycle.
Primary sourcing regions for botanical and plant-based ingredients include Central and Southern Europe, with selected certified global agricultural producers for ingredients where European sourcing is limited. Mineral forms are predominantly sourced from established European ingredient houses with documented quality management systems.
The goal of the sourcing programme is not geographic purity — it is documentation quality. The question is always: can we trace this ingredient to a specific batch, produced at a specific facility, on a specific date?
Botanical extracts (Ashwagandha, Rhodiola, Green Tea) sourced from certified agricultural producers. Each supply agreement specifies minimum active compound concentration ranges and requires harvest-batch documentation.
Chelated mineral forms (Bisglycinate, Picolinate, Methionine) are preferred for their documented absorption profiles. Sourced from European ingredient manufacturers with established quality management systems.
The Vitality & Endurance composition uses algae-derived DHA and EPA, sourced from closed-system photobioreactor cultivation to ensure a consistent active content profile across batches.
Vitamin D3 in the Core Daily formulation is derived from lichen — a plant-based source appropriate for a vegetarian-compatible composition. The active content of each batch is confirmed by the supplier certificate before use.
The Paper Trail Is the Product.
Every formulation brief — including draft versions, review notes, and the rationale for changes between versions — is retained for the lifetime of the composition. Version history is accessible and timestamped.
Each production batch has a numbered record containing the formulation version used, the supplier lot numbers for each ingredient, the date of production, and the result of the independent verification report.
Supplier qualification records are maintained per ingredient and per production source. Each record contains the supplier's current facility documentation, certificate scope, and the date of the most recent review.
