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.
Ingredients
Isinglass itself is halal — it is derived from fish swim bladders, and fish are halal without requiring slaughter. However, isinglass is most commonly used to clarify beer and wine, which are haram. In non-alcoholic juice and beverages, isinglass is a permissible processing aid. The halal status depends on the drink, not the isinglass.

Pepsin is mashbooh (doubtful) and should be avoided unless the product carries halal certification. As a food additive (E1101), pepsin is primarily sourced from pig stomachs (porcine pepsin) — making it haram. Bovine or ovine pepsin from halal-slaughtered animals is permissible, but the label simply says "pepsin" without disclosing the source. JAKIM, MUI, and IFANCA classify pepsin as doubtful unless source documentation confirms it is from a halal-certified animal or a microbial alternative.
Pepsin is a digestive enzyme that breaks down proteins (a protease). It is the primary enzyme of gastric digestion in humans and most vertebrates, secreted by the stomach lining as inactive pepsinogen and activated by stomach acid.
As a food additive (E1101 — proteases), pepsin is used as:
Commercial pepsin is extracted from stomach mucosa (the gastric lining). The principal commercial sources are:
The dominant source of commercial pepsin globally. Pig stomach mucosa is a by-product of pork slaughterhouses and is abundant and inexpensive. Porcine pepsin accounts for the majority of pepsin used in food processing and pharmaceutical manufacturing worldwide.
Extracted from the stomach lining of cattle. Available but less common commercially than porcine pepsin due to supply and cost factors.
Less commonly produced commercially; used in some traditional cheese applications.
Some recombinant pepsin (produced by fermentation using microorganisms expressing the pepsin gene) is available for research and pharmaceutical applications. Food-grade microbial pepsin is not yet widely commercially established, but is an emerging area.
Both pepsin and rennet are stomach enzymes that play a role in cheese making, but they are distinct:
Traditional animal rennet preparations contain both chymosin and pepsin — the ratio varies by animal species and age. Modern FPC preparations are pure chymosin and contain no pepsin. So a cheese made with FPC rennet has no pepsin; a cheese made with traditional calf rennet has a proportion of pepsin as part of the enzyme complex.
Pepsin presents a more acute halal concern than rennet for two reasons:
Pepsin may appear on ingredient labels as:
The processing-aid classification is a significant issue: in many cheese and meat products, pepsin may be used but not declared on the label.
JAKIM classifies pepsin as mashbooh. For any product submitted for halal certification that involves pepsin as a processing aid or ingredient, JAKIM requires source documentation. Porcine pepsin renders a product haram. Bovine pepsin from halal-slaughtered cattle may be accepted with full supply chain documentation. FPC-based chymosin (which does not contain pepsin) is the preferred and most commonly accepted alternative for cheese applications.
MUI's fatwa on animal enzymes holds that porcine-derived enzymes are haram regardless of processing. Bovine pepsin from halal-slaughtered animals is halal but requires documentation. The Indonesian mandatory halal certification framework requires processing aids to be declared and audited — pepsin used in certified halal products must be from confirmed halal sources.
IFANCA advises consumers that pepsin is likely porcine unless stated otherwise and should be treated as a doubtful ingredient. IFANCA-certified products containing pepsin have undergone source verification. Their consumer guidance is to avoid products containing unlabelled "protease" or "pepsin" unless halal-certified.
The Gulf halal standard requires that any enzyme of animal origin be from halal-slaughtered animals and that documentation be provided. Porcine-derived pepsin is not acceptable in any Gulf halal-certified product.
Not always, but predominantly yes in commercial applications. Bovine and ovine pepsin exist but are less common. Without explicit sourcing information or halal certification, treat pepsin as likely porcine.
E1101 covers all proteases including pepsin. The status depends on source. Microbial proteases (e.g., from fungi or bacteria on plant substrates) are halal. Pepsin specifically under E1101 is mashbooh — require documentation or halal certification.
No. FPC (fermentation-produced chymosin) is pure chymosin — the specific enzyme that coagulates milk. It contains no pepsin. This is one of the advantages of FPC over traditional animal rennet, which naturally contains a blend of chymosin and pepsin.
The mainstream position of JAKIM, MUI, and IFANCA does not accept istihalah for porcine-derived enzymes. These authorities hold that the porcine origin renders derivatives haram regardless of how far the enzyme has been processed from the original tissue.
Yes — when the pepsin is from halal-slaughtered animals with full documentation, or from microbial/recombinant sources. JAKIM and MUI-certified products containing pepsin have undergone source verification to confirm this.
