“Halal”, “kosher” and “vegan” all fail for the same reason more often than not: an excipient the label never mentions by source. The capsule shell, the anti-caking agent and the tablet coating are usually a bigger risk to these claims than the active ingredient itself.
This guide walks through where animal-derived material hides in a typical supplement formula, what certification actually covers, and the questions to settle before a Japanese factory can quote on a halal, kosher or vegan product.

Where animal-derived material hides in a formula
The capsule shell, the anti-caking agent, the colourant and the tablet coating are more likely to be animal-derived than the labelled active ingredient.
| Component | Common animal-derived form | Where the risk sits |
|---|---|---|
| Capsule shell | Gelatin, usually from bovine or porcine skin and bone, sometimes fish | The most common single point of failure for halal, kosher and vegan claims alike |
| Flow agent / anti-caking agent | Magnesium stearate made from stearic acid, which can come from animal fat (tallow) as well as vegetable oil | The ingredient list rarely states the source; “magnesium stearate” alone does not confirm it |
| Tablet coating / glaze | Shellac, a resin secreted by the female lac insect | Halal status is disputed among scholars; not vegan; not usually flagged as an animal-derived ingredient |
| Colourant | Carmine (cochineal), extracted from the dried bodies of the cochineal insect | Clearly not vegan; not halal or kosher under mainstream rulings |
| Botanical or herbal extract | An extract made with an ethanol (alcohol) solvent | A genuine area of disagreement among Islamic scholars, described below |
Gelatin, the most common problem
Gelatin’s acceptability under halal or kosher rules depends entirely on its animal source and how that animal was slaughtered, which the word “gelatin” alone never tells you.
Gelatin is most often produced from bovine or porcine skin and bone, with fish gelatin used less commonly. Porcine gelatin is not halal or kosher under any mainstream ruling. Bovine gelatin’s status depends on whether the animal was slaughtered according to the applicable religious method — the majority position among mainstream halal certifiers is that gelatin from cattle not slaughtered as zabihah (halal method) does not qualify, even though the animal itself is a permitted species. Fish gelatin is generally accepted as halal, provided the fish species itself is permitted, and fish gelatin from a kosher fish species can meet kosher requirements more straightforwardly than mammalian gelatin.
A hard capsule shell made from HPMC (hydroxypropyl methylcellulose), a plant-derived cellulose, avoids the question entirely: it is not animal-derived, so it does not need a halal or kosher determination on the shell itself, and it is accepted as vegan.

Alcohol-based extracts: a genuine grey area
Whether an alcohol (ethanol) solvent used to make a botanical extract is acceptable under halal rules is a real point of disagreement among Islamic scholars, not a settled yes-or-no.
Many herbal and botanical extracts use ethanol as a processing solvent, which is then largely removed but can leave a residual trace in the finished extract. Scholarly positions differ on how this is treated: some hold that ethanol from a non-grape, non-date source (for example, corn or synthetic ethanol) used for extraction rather than drinking is acceptable regardless of trace amount, while other authorities apply a stricter threshold or require the solvent to come from a specific source. Because the positions genuinely differ, and because different certification schemes apply different thresholds, a formula that depends on an alcohol-extracted ingredient needs the extraction method and residual solvent disclosed to whichever certification scheme the buyer intends to use — this is not a fact a supplement brand can resolve on its own by picking a wording.
An alcohol-free extract made with water, glycerin or propylene glycol as the solvent avoids the question, which is why it is often the simpler choice for a halal-positioned product.
Certification, and what “vegan” actually means legally
Halal and kosher certification are usually issued by private religious bodies, except where a government has made certification a legal requirement — and “vegan” has no single legal definition in most markets at all.
Most halal and kosher certification is carried out by private religious certification organisations, and this guide does not name or recommend any of them — the applicable scheme is a decision for the brand and its target market, and Sunsho Trade does not select one on a client’s behalf. Two government bodies are worth knowing because certification through them is, or is becoming, a legal requirement rather than a voluntary private scheme:
- Indonesia’s BPJPH (Badan Penyelenggara Jaminan Produk Halal, the Halal Product Assurance Organizing Agency) issues halal certificates under Indonesia’s Halal Product Assurance Law (Law No. 33 of 2014) and its 2024 implementing regulation. Mandatory halal certification for food, beverages and food additives took effect from 18 October 2024; for most other food and beverage products, including imports, the compliance deadline was extended to 17 October 2026.
- Malaysia’s JAKIM (Department of Islamic Development Malaysia), operating under the Prime Minister’s Department, is Malaysia’s federal halal certification authority for food, pharmaceuticals, cosmetics and other consumer goods.
“Vegan” has no single legal, government-set definition in the EU, the UK or the US. In each of these markets it is a voluntary claim made by the manufacturer, similar in legal status to “natural” — it must be truthful and not misleading, but there is no statutory standard of identity behind the word, unlike “organic”. This means a “vegan” claim on a Japan-made product is only as reliable as the ingredient-by-ingredient sourcing check behind it; there is no government body confirming the claim the way there would be for a regulated term.
What to fix in the specification
The specification needs a stated source, not just a name, for every excipient with an animal-derived option.
- Capsule shell: gelatin (state animal source and slaughter method) or a plant-based alternative such as HPMC
- Flow agent: magnesium stearate or stearic acid, with the source (vegetable or animal) stated, or a plant-sourced alternative
- Coating and colourants: confirm whether shellac or carmine is used, and specify an alternative if the claim requires it
- Any botanical extract: state the extraction solvent and whether residual alcohol is present
- The certification scheme the finished product must meet, and which market requires it as a legal condition of sale rather than a marketing claim
Before you ask for a quotation
- Which of halal, kosher or vegan (or more than one) the product must meet
- The certification scheme required, if any, and the market it applies to
- Full excipient list, including capsule shell, flow agent, coating and colourant
- Whether any ingredient is a botanical extract, and its extraction solvent
- First order and annual volume

Frequently asked questions
1. Is a gelatin capsule automatically not halal?
Not automatically — it depends on the source animal and how it was processed. Porcine gelatin is not accepted; bovine gelatin’s status depends on the slaughter method; fish gelatin is generally accepted, provided the fish species is permitted. An HPMC (plant-based) capsule avoids the question.
2. Can a supplement be both vegan and halal at the same time?
Yes, and the checks overlap heavily — a fully plant-derived formula with no gelatin, shellac, carmine or animal-sourced stearic acid clears most of the excipient concerns for both claims, though halal certification also covers the alcohol-extract question that a vegan claim does not.
3. Does “vegan” on a label mean it has passed a government check?
No. In the EU, the UK and the US, “vegan” is a voluntary manufacturer claim with no statutory legal definition, unlike a regulated term such as “organic”. The reliability of the claim depends on the ingredient sourcing behind it.
4. Is alcohol used in extraction always a problem for halal certification?
Not always, and Islamic scholars genuinely disagree on where the line sits — some accept ethanol from a non-grape, non-date source used purely for extraction, others apply a stricter rule. This is why the extraction method and residual solvent need to be disclosed to the specific certification scheme involved, rather than assumed.
5. Is halal certification legally required to sell in Indonesia and Malaysia?
In Indonesia, yes, for an increasing range of products, phased in under the Halal Product Assurance Law — food, beverages and food additives from 18 October 2024, with most other food and beverage products, including imports, due by 17 October 2026. In Malaysia, JAKIM certification is the recognised federal scheme, though its legal mandatory scope differs by product category and market channel, so this should be confirmed for the specific product.
