Ingredients
Pepsin (E1101) is mashbooh — doubtful and likely haram without halal certification. It is predominantly sourced from pig stomachs (porcine pepsin). Bovine pepsin from halal-slaughtered cattle is permissible but requires documentation. JAKIM, MUI, and IFANCA require source confirmation before certifying products containing pepsin.
Ingredients
Many popular vitamins and supplements contain hidden haram ingredients — from porcine gelatin capsules to carmine colouring and lanolin-derived D3. This guide breaks down exactly what to look for on the label, which certifications to trust, and which halal-certified brands are worth buying in 2026.

Isinglass itself is halal — it is derived from fish, and fish are halal without requiring slaughter. However, isinglass is most commonly used to clarify beer and wine, which are haram. When used in non-alcoholic juices, ciders (non-alcoholic), or other halal-permissible beverages, isinglass is acceptable. The halal status of any product fined with isinglass depends on whether the drink itself is halal. JAKIM and MUI consider the isinglass itself permissible; the drink it clarifies must be assessed separately.
Isinglass is a fining agent — a substance added to a liquid to cause suspended particles to aggregate and settle out, leaving a clearer liquid. It is derived from the dried swim bladders (also called sound or air bladder) of fish, most commonly:
The swim bladder is washed, dried, and processed into sheets, granules, or a liquid colloidal solution. When added to a liquid such as beer, wine, or juice, isinglass (which carries a positive charge) attracts negatively charged yeast cells and tannin particles, forming flocs that sink to the bottom of the vessel. The clarified liquid is then racked off the sediment.
The halal analysis has two distinct parts:
Fish are categorically halal in Islamic law. Fish do not require slaughter — they may be killed by any method, including by the fisherman's catch. All four major madhabs (Hanafi, Maliki, Shafi'i, Hanbali) agree on the permissibility of fish and other sea creatures (with minor scholarly variations on shellfish in the Hanafi madhab).
The swim bladder is an internal organ of the fish, not blood or a specifically prohibited part. Isinglass is produced from fish collagen — structurally analogous to fish gelatin, which is widely accepted as halal by all major certification bodies.
Conclusion on the ingredient itself: Halal. All major halal certification bodies (JAKIM, MUI, IFANCA, ESMA) accept fish-derived collagen and fish swim bladder derivatives as halal.
This is where the halal question becomes significant:
This is a technically complex question. In traditional fining:
However, studies have shown that trace quantities of isinglass protein can remain in the finished drink — enough to cause reactions in consumers with fish allergies. UK and EU regulations require allergen labelling if isinglass is used as a processing aid in beverages.
For halal purposes: The question of trace transfer is less critical than the status of the drink itself. A halal drink clarified with isinglass remains halal (isinglass being halal). A haram drink (beer, wine) clarified with isinglass remains haram — not because of the isinglass, but because of the alcohol.
Isinglass is an animal-derived product and is not vegan. Many beers, wines, and fruit juices labelled "vegan" use alternative fining agents — bentonite clay, kaolin clay, or pea protein — instead of isinglass. The vegan label is a useful secondary indicator that a product does not contain isinglass, though it does not address the alcohol content for halal purposes.
JAKIM accepts isinglass from fish as a halal-permissible processing aid in non-alcoholic beverages. Fish derivatives (gelatin, collagen, isinglass) do not require slaughter documentation under JAKIM's framework, distinguishing them from animal-derived enzymes and fats. For juice or non-alcoholic beverage manufacturers seeking JAKIM certification, isinglass is not a blocking ingredient.
MUI accepts fish-derived isinglass in halal-certified products. The broader concern for Indonesian halal certification of any beverage is whether the product is alcoholic or contains alcohol in any amount that would render it intoxicating. Isinglass in non-alcoholic juice is accepted.
IFANCA has stated that isinglass from fish is halal. Their ingredient guidance notes that the principal concern with isinglass is the alcoholic beverage context in which it is typically used, not the ingredient itself.
No — but not because of the isinglass. Beer itself is haram due to its alcohol content. The isinglass used in beer fining is derived from fish and is a halal ingredient; it does not make the beer haram. The beer was already haram due to alcohol.
No — for the same reason. Wine is haram. The fining agent is irrelevant to this determination.
They are both fish-derived collagen products, but produced differently. Fish gelatin is extracted by boiling fish skin, scales, and bones. Isinglass is specifically from the swim bladder and processed differently. Both are halal, and both are used in food and beverage applications.
Isinglass itself contains no gluten. However, beer fined with isinglass may contain gluten from malted barley. Fruit juice fined with isinglass is gluten-free (assuming no other gluten sources).
Yes. Bentonite clay, kaolin clay, and pea protein are widely used as vegan and halal fining agents in juices and beverages. These are fully halal and are increasingly used in the non-alcoholic and halal beverage industry.
