Quiet Diligence in Nutrition.
A considered daily complex for men — assembling vitamins, minerals, and natural compounds through documented sourcing and independent batch verification. Each composition begins with a single question: what does the evidence actually say?
A supplement practice built on three immovable positions
The logic behind Brastel is quiet and deliberate. There is no seasonal reformulation, no response to marketing trends. Three principles were written at founding and have not changed. They govern every ingredient selection, every supplier relationship, every batch record that leaves this facility.
Published-Research-Informed Selection
Every ingredient in every Brastel composition is referenced against published nutritional literature. No anecdotal claims. No traditional-use assertions without a corresponding evidence base. If the research is thin, the ingredient is not included.
Independent Batch Verification
Every production batch undergoes third-party laboratory analysis before release. The certificate of composition is retained in the lot record archive. Active ingredient content is verified against declared values. No batch is released without a passing verification record.
Documented Chain-of-Custody
Sourcing documentation accompanies every ingredient from the supplier facility through to the production room. Named-region materials carry an origin map entry. Cold-chain records are filed per delivery. Traceability is not optional — it is the baseline expectation.
Three compositions. One daily routine.
Mineral Foundation Complex
Zinc supports normal cognitive function and immune health. Magnesium contributes to normal energy metabolism and reduces tiredness. Together, these two minerals form the elemental base of the Brastel daily routine.

Energy & Stamina Complex
Vitamin B12 contributes to normal energy production. CoQ10 is involved in cellular energy production. This composition is formulated for men whose physical activity demands consistent nutritional support throughout the week.

Immune & Resilience Daily
Vitamin D3 supports normal function of the immune system. Vitamin C supports the normal function of the immune system. Selenium contributes to protection of cells from oxidative stress. A comprehensive daily composition assembled for men's health.
Full composition detailsThe case for a quieter kind of men's supplement
There is a quiet logic to how a body uses micronutrients across a day — a logic that resists the language of performance marketing. Zinc moves through cellular processes. Magnesium participates in hundreds of enzymatic reactions. These are not dramatic interventions; they are slow, consistent contributions that the body relies on when the baseline is maintained.
Brastel was assembled from the position that a daily supplement for men does not need to make loud claims. It needs to contain what the evidence recommends, at concentrations that published nutritional research considers adequate, verified by an independent laboratory, and delivered in a form that a person will actually maintain as a daily practice.
The Glodok facility in Jakarta is where formulation decisions are reviewed against the lot record archive. Every revision to a composition is dated and filed. There are no silent reformulations. If an ingredient ratio changes, the archived revision notes change with it.
Each batch is assigned a unique lot code at the point of production. The code maps to a complete sourcing brief, ingredient ratio sheet, and third-party analysis certificate. The archive currently holds 38 complete lot records dating from the first production run.
Vitamins and minerals for men — what each one does
Ingredient profiles in Brastel supplements are selected based on published nutritional research and undergo independent batch verification for quality and labelling accuracy.
Zinc
Supports normal cognitive function and immune health. Elemental zinc is derived from documented suppliers with full chain-of-custody records.
Magnesium
Contributes to normal energy metabolism and reduces tiredness. Batch concentration is independently verified against the declared elemental profile.
Vitamin D3
Supports normal function of the immune system. Cholecalciferol concentration is recorded per batch and archived against the lot code at dispatch.
Vitamin B12
Contributes to normal energy production. Methylcobalamin form is used for its stability profile. Active content verified at every production run.
Vitamin C
Supports the normal function of the immune system. Ascorbic acid concentration is declared per serving and confirmed by independent analysis.
Selenium
Contributes to protection of cells from oxidative stress. Elemental profile is characterised per batch within the lot record archive.
CoQ10
Involved in cellular energy production. Ubiquinone concentration is verified at third-party laboratory prior to each batch release.
Iron
Contributes to normal oxygen transport in the body. Ferrous form sourced from a documented facility with active food-grade processing standards.
