Marine, Bovine, and Vegan: Which Collagen Does Not Contain Pork?

November 17, 2025 •

4 min read

Over 60% of collagen supplements are sourced from bovine and porcine origins, necessitating alternative options for those with dietary or religious restrictions. For individuals asking which collagen does not contain pork, there are several viable animal-based and plant-derived options available to support health and wellness.

Quick Summary

This guide provides an overview of collagen sources suitable for pork-free diets, detailing marine, bovine, chicken, eggshell, and vegan alternatives for skin, joint, and overall wellness.

Key Points

Marine Collagen is Excellent for Skin: Sourced from fish, marine collagen is primarily Type I and is highly bioavailable for skin health and elasticity.
Bovine Collagen is Multi-Beneficial: Derived from cows, bovine collagen provides both Type I and Type III collagen for broader support of skin, hair, nails, and joints.
Check for Halal/Kosher Certification: For religious dietary requirements, always verify that bovine or marine collagen products are explicitly certified Halal or Kosher to ensure proper sourcing and processing.
Vegan Options are 'Boosters,' Not True Collagen: Vegan products do not contain actual collagen but rather provide the plant-based amino acids and vitamins needed to help the body produce its own.
Chicken Collagen Targets Joints: Sourced from chicken cartilage, this type is rich in Type II collagen, which is specifically beneficial for supporting joint and cartilage health.
Bioavailability Varies: Due to smaller peptide sizes, marine collagen may be more easily absorbed than some other animal-based options, though high-quality hydrolyzed bovine is also very effective.

Understanding the Need for Pork-Free Collagen

Collagen is the body's most abundant protein, providing structure to skin, bones, muscles, and tendons. It is a popular supplement for supporting skin elasticity, joint health, and nail strength. While collagen is naturally derived from animal connective tissues, not all sources are suitable for everyone. Religious and dietary laws, such as Halal and Kosher, strictly prohibit the consumption of pork or its by-products. Vegetarians and vegans also require alternatives. Thankfully, the supplement industry offers numerous excellent options sourced from marine life, cattle, poultry, and plants.

Marine Collagen

Derived from the skin, scales, and bones of fish, marine collagen is an excellent pork-free option. It is primarily rich in Type I collagen, which is most beneficial for skin health, hydration, and elasticity.

Key features of marine collagen:

High Bioavailability: Marine collagen peptides are known for their small particle size, which allows for quicker and more efficient absorption by the body.
Type I Collagen: It predominantly provides Type I collagen, making it a favorite in the beauty industry for supporting skin, hair, and nails.
Suitable for Pescatarians: Since it comes from fish, it is a suitable choice for those who do not consume land animals.

Bovine Collagen

Sourced from the hides and bones of cows, bovine collagen is another popular pork-free alternative. It typically contains both Type I and Type III collagen, offering a broader range of benefits for overall wellness.

Key features of bovine collagen:

Type I and III Collagen: This combination makes it beneficial for skin, hair, nails, bones, joints, and the gut lining.
Halal and Kosher Certified: High-quality bovine collagen from reputable brands can be certified Halal or Kosher, ensuring strict adherence to religious dietary laws.
Widely Available and Cost-Effective: Bovine collagen is a well-established and generally more affordable option compared to other sources.

Chicken Collagen

Extracted from chicken cartilage, skin, and bones, this collagen is another non-pork alternative. It is especially rich in Type II collagen, the primary component of cartilage.

Key features of chicken collagen:

Rich in Type II Collagen: This makes it particularly beneficial for supporting joint health and mobility.
Targeted Joint Support: Many supplements targeting joint and cartilage issues use chicken collagen specifically for its Type II content.

Vegan and Plant-Based Collagen Alternatives

For those following a vegan or plant-based diet, genuine collagen is not an option as it is exclusively found in animals. However, many products offer vegan collagen boosters that provide the necessary building blocks and cofactors for the body to synthesize its own collagen.

Ingredients in vegan collagen boosters often include:

Amino Acids: Glycine, proline, and lysine, which are the main components of collagen.
Vitamin C: An essential cofactor for collagen synthesis.
Zinc and Copper: Important minerals that assist in collagen production.
Silica: Sourced from bamboo or other plant sources, it supports connective tissue.

Some brands are now also using biotechnology to produce lab-grown vegan collagen from microbes like yeast, offering a bio-identical alternative.

Choosing the Right Pork-Free Collagen for You

Selecting the best collagen depends on your individual needs and dietary restrictions. If your primary goal is to improve skin health, marine collagen might be the ideal choice due to its high concentration of Type I collagen and superior bioavailability. For those seeking broader benefits for skin, hair, nails, and joints, a certified Halal or Kosher bovine collagen supplement is an excellent option. For focused joint support, chicken collagen, with its high Type II content, is often recommended. For vegans and vegetarians, specialized "collagen boosters" containing plant-derived amino acids and vitamins are the way to go. Regardless of your choice, always look for products from reputable brands that provide transparency in their sourcing and, if applicable, offer clear Halal or Kosher certifications. By carefully considering your options, you can find a high-quality collagen supplement that aligns with your health goals and personal values.

By making an informed decision, you can effectively incorporate collagen into your routine without compromising your values.

Frequently Asked Questions

Both marine (fish) and bovine (cow) collagen are excellent pork-free options. Marine collagen is rich in Type I collagen, primarily targeting skin health, while bovine contains both Type I and Type III, offering broader support for skin, hair, nails, and joints.

No, true collagen can only be found in animals. Vegan products provide 'collagen boosters'—nutrients, amino acids, and vitamins—that help the body synthesize its own collagen.

To ensure your bovine collagen is Halal or Kosher, you must look for products that are explicitly certified by a recognized certifying body. This guarantees the animals were sourced and processed according to religious dietary laws.

Fish collagen is generally safe, but individuals with a shellfish or fish allergy should be cautious. If you have such allergies, bovine collagen is a safer alternative.

Chicken collagen is a non-pork alternative that is particularly high in Type II collagen. It is often chosen by individuals who specifically want to support their joint and cartilage health.

You can get collagen and its building blocks from various pork-free foods. This includes bone broth from certified animals, chicken skin, fish, and egg whites. Plant-based foods rich in vitamin C and amino acids also support collagen production naturally.

The quality of collagen depends more on the manufacturing process and brand reputation than the source itself. Look for hydrolyzed collagen peptides from reputable brands for optimal absorption, regardless of the source.
