The short answer is: Yes, marine collagen is halal under certain conditions.

Marine collagen extracted from fish is permissible according to the majority of Islamic scholars, provided the fish are caught directly from the sea and the ingredients are free from any prohibited substances such as alcohol or pork derivatives. The verse states: {Lawful to you is the game of the sea and its food} (Al-Ma'idah: 96).

Cosma Collagen is officially certified Halal and is extracted entirely from pure marine fish.

What is marine collagen?

Marine collagen is a protein extracted from fish skin and the shells of certain shellfish. It is characterized by its small (hydrolyzed) molecular size, which allows for up to 1.5 times faster absorption compared to animal collagen.

Marine collagen primarily contains type I collagen, which is responsible for:

  • Tighten skin and reduce wrinkles
  • Strengthening hair and nails
  • Supporting joint and cartilage health
  • Improving skin elasticity

Why do some people question its permissibility?

The question usually comes from three main points:

  • Source: Some collagen products are derived from pigs or cows that were not slaughtered according to Islamic law.
  • Added ingredients: Some supplements contain preservatives, including alcohol.
  • Halal certification: The absence of an official halal certificate raises suspicion, even if the source is maritime.
