Collagen supplements are popular for skin, hair and joints. Most collagen comes from animals, so the source decides whether a product is halal. This guide compares the two main halal options.
Marine collagen
- Made from fish skin and scales.
- Widely accepted as halal, because fish do not require slaughter.
- Mostly type I collagen, the main type in skin.
- Not suitable for people with fish allergies.
Bovine collagen
- Made from cattle hides and bones.
- Halal only if the cattle were slaughtered Islamically and the product is certified. “Grass-fed” does not mean halal.
- Provides types I and III collagen.
Sources to avoid
Porcine (pig) collagen is common in cheaper supplements and cosmetics and is not halal. If a label does not state the source, ask the manufacturer or choose a certified product.
What halal certification covers
A recognised certifier (for example IFANCA, Islamic Services of America, HMC, HFA or JAKIM) checks the raw-material source, slaughter, processing and cross-contamination on shared lines. Check the certifier’s logo and look the product up on the certifier’s website.
Does collagen work?
Some randomised trials suggest collagen supplements can improve skin hydration and elasticity and may ease joint pain, but many studies are small or industry-funded. Eating enough protein and vitamin C – which your body needs to make collagen – matters too.

Frequently asked questions
Is marine collagen better than bovine?
Neither is clearly better. Marine is mostly type I; bovine gives types I and III. Choose based on allergies and certification.
Do collagen creams need to be halal?
Scholars are generally more lenient with products applied to the skin, but many Muslims prefer halal-certified cosmetics.
Is vegan collagen real collagen?
No. “Vegan collagen” products contain nutrients that support your body’s own collagen production.
