As collagen continues to take the spotlight in the wellness world, it’s essential to understand the options available. Marine and bovine collagen both offer unique benefits, but which one is right for you?

Let’s dive into the distinctions between these two sources, guided by the principles of ancestral nutrition.

 What is collagen?

Collagen is a structural protein found abundantly in the human body. It provides strength and flexibility to our skin, bones, joints, and connective tissues. There are various types of collagen, each supporting different parts of the body:

1. Type I collagen: The most abundant, responsible for skin elasticity and the structural support of bones and tendons.
2. Type II collagen: Predominantly found in cartilage, supporting joint health and cushioning
3. Type III collagen: Essential for gut lining, blood vessels, and organ structure, often working alongside Type I.

Collagen supplements typically derive from two main sources: marine (from fish) and bovine (from cow parts), each offering its own unique benefits.

Marine collagen vs Bovine collagen

1. Benefits

● Marine collagen: Composed mostly of Type I collagen, marine collagen is especially beneficial for skin health. It has been shown to improve skin elasticity, reduce wrinkles, and boost hydration. Additionally, marine collagen can support bone health and aid in wound healing.
● Bovine collagen: Bovine collagen provides both Type I and Type III collagen, making it a more comprehensive supplement. While it certainly benefits the skin, its impact extends to gut health, joint function, and muscle repair. The presence of Type III collagen is essential for maintaining a healthy gut lining, which plays a key role in digestion and immune function. Bovine collagen’s broader benefits make it ideal for those looking for full-body nourishment, beyond just skin improvements.

2. Bioavailability and absorption

● Marine collagen: Known for its smaller molecular size, marine collagen is believed to be more bioavailable, meaning it can be absorbed more quickly and efficiently by the body. This makes it a fast-acting option for targeting skin and hair health.
● Bovine collagen: While bovine collagen molecules are slightly larger, they are still easily digested and absorbed, especially when it comes to supporting joint health and gut function. The broader range of collagen types in bovine collagen makes it a more comprehensive option for long-term, full-body benefits.

3. Sustainability and ethical considerations

● Marine collagen: Marine collagen sourced from wild-caught fish or fish skin,
byproducts of the fishing industry, can be a sustainable option. However, ethical
concerns surrounding overfishing and fish farming's environmental impact must be
considered when choosing marine collagen.
● Bovine collagen: Grass-fed, pasture-raised bovine collagen is an excellent choice for those concerned about sustainability and ethical sourcing. Cattle raised on regenerative farms contribute to better soil health, increase biodiversity, and promote ethical animal treatment. Not only do these practices improve the environment, but they also result in higher-quality collagen, richer in essential amino acids like glycine, proline, and hydroxyproline. Bovine collagen from well-raised cattle offers a sustainable, nutrient-dense option that supports both your health and the planet.

4. Dietary considerations

● Marine collagen: Marine collagen is a great option for those avoiding red meat or
following a pescatarian diet. It’s also naturally free from dairy and gluten, making it
suitable for individuals with a variety of dietary sensitivities.
● Bovine collagen: Bovine collagen aligns well with paleo and keto diets, providing a nutrient-dense, high-protein option that supports overall joint, gut, and muscle health. Its broad range of collagen types makes it a closer match to the collagen naturally found in the human body, which can make it particularly effective for those looking for holistic support.

5. Cost and availability

● Marine collagen: Due to its sourcing and typically smaller yields, marine collagen
tends to be more expensive.
● Bovine collagen: Bovine collagen is generally more affordable and widely available, however it is important to ensure a grass-fed high quality source

Which one is right for you?

Deciding between marine and bovine collagen supplements depends largely on your health priorities and dietary preferences:

● If your main goal is faster absorption and skin-focused benefits, marine collagen may be the better option

● Meanwhile, bovine collagen’s blend of Type I and Type III collagen provides deeper nourishment for the body and is thus is ideal for those not only seeking to enhance skin elasticity but also fortify joints, repair muscles, and maintain a healthy gut lining

Whichever you choose, by integrating collagen into your daily routine, you can restore vitality and strength to your body, just as our ancestors did through whole-animal diets.

Listen to your body, honour your roots, and let collagen support your path to wellness
