What this range covers
The functional-nutrient range sits at the boundary between medicines and food supplements, and that boundary is the single most important fact for a buyer. Collagen peptides, biotin, levocarnitine, glutathione and body-fitness ingredients are sold in most markets as food supplements or nutraceutical ingredients, not as medicines. They have no entry on the WHO Model List of Essential Medicines, and they cannot be promoted with therapeutic claims. The WHO entries in this area cover vitamins and minerals used to treat or prevent deficiency — a different regulatory category with a different dossier route.
What the published guidance says
- Vitamins and minerals appear on the Model List as medicines, with defined strengths and forms — the listing specifies the presentation, not just the nutrient, so a supplement-grade ingredient and a listed medicine are not interchangeable in a public programme. WHO Model List of Essential Medicines
- Essential-medicines listing is about public-health priority, not product quality — a nutrient outside the list is not inferior; it simply follows a different route to market. WHO essential medicines fact sheet
- Claim language is set by the destination market. Under EU rules, health claims for food supplements may only be made if they are on the authorised list; in the United States, structure/function claims require the standard disclaimer. Copy written for one market is frequently unlawful in another.
Which forms we supply
- Powders and granulates — bulk powder in fibre drum or food-grade lined carton, with particle size distribution stated.
- Direct-compression and capsule grades — flow and compressibility characterised so the ingredient can be run on a tablet press or capsule filler.
- Premixes and custom blends — multi-component blends to a stated assay, with the blend homogeneity data in the release file.
- Finished supplement presentations — tablets, hard capsules, sachets and oral liquids, produced under the same quality system as the medicine range.
Specification, testing and documentation
Every ingredient is quoted against a written specification that names the assay method, the identification method and the limits for heavy metals, microbiological quality and residual solvents. Release testing typically covers:
- Assay and identification against the agreed method or a reference standard
- Heavy metals and elemental impurities
- Microbiological limits, including total plate count, yeasts and moulds, and specified organisms
- Loss on drying or water content, and ash
- Residual solvents where the process requires a solvent
- Particle size distribution, bulk and tapped density, for powder grades
- Allergen, GMO and, where relevant, non-animal origin declarations
Documentation shipped with each batch: certificate of analysis, specification, method of analysis, allergen and origin statements, GMP certificate, and the safety data sheet where the material requires one.
Regulatory route by market
The same ingredient can be a food supplement in one country and a registered medicine or a traditional herbal product in another. Before quoting, tell us the destination market and intended claim position. We then confirm which of the following the product needs to satisfy, and what documentation the authority is likely to request:
- Food supplement or nutraceutical notification
- Ingredient-level dossier with safety and stability data
- Label and claim review against the destination rules
- Import permit, free-sale certificate and certificate of origin
Where a product does hold a medicine route in your market — for example a vitamin or mineral preparation with a therapeutic indication — the full CTD route applies and we support the filing as for any other registered product.
Questions buyers ask
What is the difference between a functional nutrient and an essential medicine?
Regulatory route, not quality. Essential medicines are those the WHO Model List treats as public-health priorities and specifies by strength and dosage form; functional nutrients such as collagen, biotin, levocarnitine and glutathione are supplied as food supplements or ingredients and cannot be promoted with therapeutic claims.
Can you supply an ingredient that is not on the WHO Model List?
Yes. The Model List governs programme procurement of essential medicines; it does not restrict what may be manufactured or traded. We confirm the specification and the regulatory route for the destination market before quoting.
Do you provide allergen and origin declarations?
Yes. Allergen statements, non-GMO and non-animal origin declarations are part of the standard documentation set where the material is used in a supplement formulation.
What claims can go on the label?
Only those permitted in the destination market. We do not draft copy that goes beyond the authorised claim list, because an unapproved health claim is grounds for withdrawal of the product in most jurisdictions.
