This is a labelled worked example, not a client case study. The brand, the brief and every number on this page are assumptions or calculations from those assumptions. No client data, measured results or approval outcome are reported. It shows how Food Research Lab would plan curcumin supplement registration in the UAE, using Dubai Municipality’s health-supplement guideline[1], the Emirates Drug Establishment (EDE) marketing-authorisation requirements[2] and published curcumin pharmacokinetic studies[3][4][5].
For other labelled worked examples, see our ashwagandha root extract capsule and vitamin D3 supplement case studies.
A brand wants a once-daily curcumin capsule for adults in the UAE, sold through pharmacies and online. It wants an enhanced-absorption format and a general well-being claim, and it wants the product registrable before it commits to a supplier. Survey data suggest a sizeable market: 47.8% of 600 adults in a 2026 UAE survey had ever used dietary supplements, and 98.7% of 448 adults in a 2022 online survey reported using herbal medicines, although both used convenience samples[6][7].
| Item | Assumption |
|---|---|
| Product | Turmeric (Curcuma longa rhizome) extract capsule, two capsules a day |
| Declared dose | 400 mg curcuminoids per day |
| Extract | Standardised to 95% curcuminoids (supplier specification) |
| Format options | Extract with piperine (black pepper extract), or a phospholipid (lecithin) complex |
| Claim | General well-being; no disease or absorption claim unless evidence supports it |
| Shelf life target | 24 months in hot, humid storage |
| Capsule shell | Gelatin or HPMC (decided by halal documentation and cost) |
Classification decides the rules, so it comes before formulation. Dubai Municipality’s guideline (Version 2, 4 May 2024) treats botanicals and herbs in capsules, tablets, powders and liquids as health supplements, provided they are not intended to treat, diagnose, prevent or cure disease. It places Ayurvedic, Chinese medicine and traditional medicine products outside that category[1]. A turmeric extract capsule with a well-being claim fits the health-supplement definition; the same product sold as an Ayurvedic remedy or with a joint-disease claim would not.
The guideline’s Annex 3 lists banned ingredients. Curcuma longa and Piper nigrum are not on it, but several herbs often blended with turmeric are, including ashwagandha, shilajit and Terminalia arjuna[1]. Any change to the formula therefore goes back through this check.
| Item | Dubai Municipality (Montaji)[1] | Emirates Drug Establishment[2] |
|---|---|---|
| Scope | Health supplements for the Dubai market; Ayurvedic and traditional medicines excluded | Healthcare products for general sale, including dietary supplements and herbal products |
| Applicant | Company incorporated in Dubai, or with a Dubai warehouse and trade licence | Marketing-authorisation holder registered with the EDE |
| Validity | 5 years | 5 years from committee approval |
| Published timing and fees | Not stated in the guideline | 45 working days; AED 100 application and AED 5,000 registration |
| Halal | Halal certificate may be requested for animal-derived ingredients | Halal certificate required |
Which route applies depends on the product and the emirates where it will be sold, so we confirm the pathway with the authority before the dossier is built. Our guide to herbal supplement claims in the UAE covers the claim side of that decision.
Curcumin is poorly absorbed, and the evidence for each enhanced format is narrower than marketing suggests:
A 2023 review of clinical trials reaches a similar view: formulations differ widely, and results depend on what is measured[8]. The team therefore shortlists both routes and makes no absorption claim unless finished-product pharmacokinetic data, with the analyte stated, support it. The science behind each format is set out in our cluster guide to curcumin bioavailability.
Safety belongs in the same decision. In August 2023 Australia’s Therapeutic Goods Administration (TGA) warned that turmeric and curcumin products may rarely cause liver injury, after 18 reports up to 29 June 2023, one of them fatal, and said the risk may be higher for products with enhanced bioavailability or higher doses[9]. The dossier’s safety section should address this.
| Route | Published evidence | Formulation impact | Claim position |
|---|---|---|---|
| Extract + piperine | Large increase in one 1998 study[3]; no benefit in a 2025 reappraisal[5] | Small added mass; piperine level from supplier | No absorption claim without product data |
| Phospholipid complex | About 29-fold total curcuminoids, as metabolites[4] | Carrier adds fill weight | Claim must match the analyte measured |
The dose comes first. With a declared 400 mg of curcuminoids a day and an extract assayed at 95% curcuminoids, the extract needed is 400 ÷ 0.95 ≈ 421 mg a day, or about 211 mg per capsule at two capsules a day (Table 4). A phospholipid complex carries much less curcuminoid per gram, so the same declared dose needs a heavier fill; if the complex were 20% curcuminoids (assumed), the daily fill would be 400 ÷ 0.20 = 2,000 mg, which would force more capsules or a lower declared dose.
| Parameter | 95% extract | Complex at 20% curcuminoids |
|---|---|---|
| Declared curcuminoids | 400 mg/day | 400 mg/day |
| Material needed per day | 400 ÷ 0.95 ≈ 421 mg | 400 ÷ 0.20 = 2,000 mg |
| Per capsule, two a day | ≈ 211 mg | 1,000 mg |
The daily intake also sets the contaminant budget. Dubai Municipality’s adult limits are per day: 20 µg lead, 6 µg cadmium, 10 µg arsenic and 20 µg mercury[1]. At about 0.42 g of extract a day, the lead limit allows up to roughly 47 ppm in the extract; at 2 g of complex, roughly 10 ppm. The heavier the fill, the tighter the specification. How lead and undeclared drugs lead to recalls is covered in our herbal supplement recalls analysis.
Storage in the Gulf is hot, and the dossier needs stability data that reflect it. WHO stability guidance defines long-term conditions of 30 °C/65% RH (zone IVa) and 30 °C/75% RH (zone IVb), with 40 °C/75% RH for accelerated studies[10]. The worked-example plan uses three batches in the final pack, long-term storage at 30 °C/75% RH with pulls at 0, 3, 6, 9, 12, 18 and 24 months, and accelerated storage at 40 °C/75% RH for six months (assumed design).
Each pull checks curcuminoid assay against the label, appearance and moisture, and selected pulls check microbiology against Dubai Municipality’s Annex 2 limits for herbal products: E. coli, Staphylococcus aureus and Salmonella absent, yeasts and moulds up to 1,000 CFU/g, aerobic bacteria up to 100,000 CFU/g and coliforms up to 10 CFU/g[1]. Release and end-of-shelf-life targets follow the logic in our guide to supplement label claims and overage in the UAE.
Dubai Municipality’s guideline lists the documents for a health-supplement dossier, and the EDE lists its own[1][2]. In this example, each document maps to a workstream already running (Figure 1):
| Document | Required by | Source in this example |
|---|---|---|
| Free sale certificate, or certificate of pharmaceutical product | DM §9.1; EDE[1][2] | Manufacturer and authority in the country of origin |
| Ingredient report with botanical name and plant part | DM §9.2[1] | Formula: Curcuma longa rhizome extract, piperine source |
| Analysis report (certificate of analysis) | DM §9.3[1] | Release testing of the finished product |
| GMP or equivalent quality certificate | DM §9.4[1] | Manufacturing site |
| Laboratory test report from a certified lab using accredited methods | DM §9.5, Annex 2[1] | Heavy metals, microbiology, assay |
| Halal certificate; clinical studies for label claims; safety assessment | DM §9.6 (on request); EDE (halal)[1][2] | Capsule shell and ingredient sources; PK data only if an absorption claim is made |
| Statement that the product is free of heavy metals, hormones, steroids and other harmful substances | EDE[2] | Supported by the lab test report |
| Detailed composition and label artwork | EDE[2] | Frozen formula and draft label |
Registration is a documented workflow, not a guarantee of approval.
Dubai Municipality requires the label to show, in English and/or Arabic, the brand and product names, manufacturer, country of origin, ingredients with botanical names, pack size, production and expiry dates, storage conditions, daily dose, intended use, a health warning and the batch number[1]. Structure/function claims must be substantiated by ingredient-based evidence and, when necessary, product-based evidence. Annex 4 prohibits disease claims, including musculoskeletal and anti-inflammatory claims, and words such as “Effective” and “Anti-aging”[1]. For curcumin, that rules out joint-disease and anti-inflammatory wording; a statement that the product is better absorbed is a product claim that needs product-based data. Advertising, including social media, needs pre-approval through Montaji[1].
Halal status is documented in the file: a gelatin capsule needs a halal certificate for its animal source, while an HPMC capsule avoids the animal-source question[1][2].
It shows sequence rather than outcome. Classifying the product, fixing the dose and fill, setting the contaminant budget, planning stability and agreeing claim wording before the dossier is assembled means no step reopens another. It also shows where evidence is needed: an enhanced-absorption claim needs finished-product pharmacokinetic data, while a well-being claim on a correctly classified product needs far less.
Food Research Lab, based in Chennai, India, helps brands take herbal supplements such as curcumin capsules from brief to a UAE-ready file. Our herbal formulation team selects the format, fixes dose and fill weight and writes the specifications. Our regulatory and scientific research team classifies the product, checks claims and prepares the dossier for Dubai Municipality or the EDE. Shelf-life studies, curcuminoid assays and heavy-metal testing are run or arranged through accredited partner laboratories. See also our UAE services.

No. It is a labelled worked example. The brand, the 400 mg curcuminoid dose, the 95% extract, the shelf-life target and the stability design are assumptions, and the tables are calculations from them. No client, measured result or approval outcome is reported. It shows how FRL would plan a curcumin supplement for UAE registration.
A turmeric or curcumin capsule that is not intended to treat or prevent disease fits Dubai Municipality’s health-supplement definition, and neither turmeric nor black pepper is on the guideline’s banned-ingredient list. The same product presented as an Ayurvedic remedy, or with a disease claim, falls outside that route and needs a different classification.
Dubai Municipality asks for a free sale certificate, an ingredient report with botanical names and plant parts, a certificate of analysis, a GMP or equivalent certificate and a certified lab test report, plus halal, clinical or safety documents on request. The EDE route also requires a halal certificate and a composition certificate.
The evidence is mixed. A 1998 study reported a 2000% increase in curcumin bioavailability when 20 mg of piperine was added to 2 g of curcumin. A 2025 crossover study in nine healthy men found piperine gave no benefit and unconjugated curcumin stayed below 2 nM in most cases.
Only with evidence for the finished product. Dubai Municipality requires structure/function claims to be substantiated by ingredient-based and, when necessary, product-based evidence. An absorption claim describes the product itself, so it needs pharmacokinetic data on that formulation, stating which form of curcumin was measured. Disease and anti-inflammatory claims are prohibited.
For hot, humid markets, WHO stability guidance defines long-term storage at 30 °C/75% RH (zone IVb), or 30 °C/65% RH (zone IVa) where humidity is not an issue, and accelerated storage at 40 °C/75% RH. Test the finished product in its final pack across the full shelf life.
