Marine vs Bovine Collagen - What's the Difference?

We all know the benefits of collagen powders, but which collagen powder or supplement should you choose - Marine or Bovine collagen?

Or, if you're new to the world of beauty powders and collagen supplements, what do these two forms of collagen even mean?

Firstly, what is collagen and why it's important?

Collagen is a protein found in our body that promotes the healthy functioning of skin, hair, nails, bones, muscles, tendons and ligaments.

Collagen plays an important role in tissue development and repair - it's basically what binds us together.

When it comes to the skin, these are a few of the benefits of collagen:

  • Gives the skin elasticity
  • Promotes hydration
  • Firms the skin
  • Promotes younger-looking skin


What are the collagen types?

Type I Collagen
- This is the amplest collagen type found in the body, and is primarily known to minimise fine lines and wrinkles, increase hydration and elasticity. Also helps repair muscles, bones, eyes, tendons and teeth. Widely known for improving the strength of nails and hair.

Type II Collagen
- This type of collagen is a component of the cartilage in the body. Collagen II work to reduce chemicals and fight against pain and swelling or is more used in joint health.

Type III Collagen
- This type of collagen is the building block of the major tissues that give us our structure, stretching, and strength. It is found in internal organs and skin.

It plays a major role in repairing and healing our skin and gut.

Collagen Type III is mostly utilised together with collagen Type I.

What is Marine Collagen?

Marine collagen is sourced from fish's skin.

Marine collagen is made up of collagen peptides Type I and Type II, and it is primarily known for replenishing and restoring collagen in the skin.

Marine collagen has a higher bioavailability, which means our body is able to break it down and absorb this type of collagen easier.

What is Bovine Collagen?

Bovine collagen is known as "beef collagen", and it is derived from cows.

It is made up of collagen Type I and Type III and it primarily replenishes the gut and repairs and heals joint health. It also works to improve skin and hair health, since skin health always starts with a balanced gut health!


What type of Collagen should I use?

In short, whether Marine or Bovine Collagen is better for you will depend on the results you want to achieve.

The collagen I personally use and recommend is Bestow Beauty - which is Marine Collagen.

Bestow Beauty sources their collagen from a single species of freshwater fish, sustainably farmed in fresh, tropical waters. Once harvested, they produce pure, pharmaceutical-grade collagen peptides.

Why does Bestow uses freshwater Marine collagen?


  • It is a sustainable, eco-friendly collagen source.
  • Offers superior bioavailability compared with beef and pork collagen.
  • Is free of heavy metals and contaminants.
  • It has a collagen profile that is closely aligned with the collagen found in human skin.
  • Freshwater collagen is believed to be the most compatible option for the skin.
  • It is full of peptides
  • It has one of the lowest molecular weights on the market, which is the reason why it is so bioavailable.

Who is it suitable for?

It is beneficial for everyone. Collagen production begins to decline in our body in mid 20s, and it drops dramatically when we reach 30-years-old. Later on, it dips again for women, when reaching menopause.

Bestow Collagen Boost helps to offset the decline and slow the rate of ageing.

Collagen #TopTip

Collagen makes up for one third of the protein of the whole human body, and there are 28 different forms of collagen in our entire body. 90% of those are types I, II, and III collagen.

This is why dermal needling is one of the best rejuvenation skin treatments to have, as it naturally optimises Type I, II collagen in our skin
