If you're looking for glowing skin, faster muscle repair, and stronger hair, you might be wondering whether marine or bovine collagen is the right choice. Both offer great benefits, but they have key differences.

Let's dive in and find out which one is better for your goals.


What Is Marine Collagen?

Marine collagen, also known as fish collagen, is a popular choice for those seeking to improve their skin health, joint function, and overall collagen support. It's a great option if you avoid red meat, but keep in mind that it's not suitable for vegetarians or vegans.

Key Facts about Marine Collagen:

  • It's sourced from fish.

  • It's rich in Type 1 collagen, which makes up 90% of our hair, skin, and nails.

  • Marine collagen is known for its high bioavailability, meaning your body can absorb it quickly.

  • It's a great option for pescatarians or those who avoid red meat.

What Is Bovine Collagen?

Bovine collagen is derived from cows and is not suitable for vegetarians. It's a fantastic, versatile option that's often found in both flavoured and unflavoured powders. Don't worry, it won't taste like beef! You can find it in delicious flavours like lemon and berries.


What type of collagen is bovine collagen?

Bovine collagen usually contains type 1 (makes up 90% of our hair, skin and nails) and type 3 collagen (builds cartilage and repairs gut lining).

Key Facts about Bovine Collagen:

  • It's sourced from cows.

  • It typically contains both Type 1 and Type 3 collagen.

  • Type 1 is essential for hair, skin, and nails.

  • Type 3 is crucial for building cartilage and repairing the gut lining.

  • This makes it a popular choice for people with gut issues and active individuals.

Marine Collagen vs. Bovine Collagen

What are the reasons to try marine collagen over bovine collagen?

  • If you want faster results (it absorbs quicker)
  • You’re a pescatarian.
  • You avoid red meat.
  • Contains type 1 collagen (makes up 90% of our hair, skin and nails).

What are the reasons to try bovine collagen over marine collagen?

  • If you have a shellfish allergy.
  • Better for those with gut problems.
  • Contains type 1 (makes up 90% of our hair, skin and nails) and type 3 collagen (builds cartilage and repairs gut lining).
  • Better for active people or gym goers.

Choose marine collagen if you want fast results and are a pescatarian or simply prefer to avoid red meat. Its focus on Type 1 collagen makes it excellent for improving the health of your skin, hair, and nails.

Choose bovine collagen if you have a shellfish allergy, need support for your gut health, or are an active person who wants to support their joints and muscles. Its combination of Type 1 and Type 3 collagen offers broader benefits.

Which type of collagen is absorbed faster?

Marine collagen is generally known for its high bioavailability, which means it may be absorbed into your body more quickly than bovine collagen. This can lead to faster-acting results, particularly for skin health.

Can I take both marine and bovine collagen?

Yes, you can. There's no harm in combining both marine and bovine collagen supplements. In fact, doing so could provide the benefits of both collagen types (Type 1 and Type 3), giving you a more comprehensive approach to health.

I have a shellfish allergy. Can I take marine collagen?

No. If you have a shellfish allergy, you should avoid marine collagen. Bovine collagen is a safe and effective alternative for you.
