What is Collagen and what is the Difference between Bovine and Marine Collagen?

Collagen provides structure and support to our skin, muscles, bones, and connective tissues. However, collagen levels begin to decrease around the age of 30. Fortunately, we can support our collagen levels through dietary sources and supplements, which may help maintain joint health, skin appearance, and hair and nail strength. Collagen supplements may also play a role in supporting fitness goals by aiding mobility and muscle maintenance, potentially benefiting overall weight management strategies as well.

At WillPowders, we’re often asked about the difference between bovine and marine collagen. Our collagen is derived from bovine sources—a choice we made with careful consideration and research. While some articles suggest that marine collagen may be superior, research does not universally support these claims. Here’s why we stand by our decision to use bovine collagen:

1. Composition and Functionality: Marine collagen is composed of Type 1 collagen, which primarily supports skin, hair, and bone health. Bovine collagen, on the other hand, includes both Type 1 and Type 3 collagen, which may support not only skin, hair, and bones but also muscles, arteries, and organs—vital elements for overall health and longevity. Research shows that bovine collagen’s composition may offer broader benefits than marine collagen.
2. Sustainability and Ethical Sourcing: We prioritise sustainability at WillPowders. Research into marine collagen production highlights concerns with overfishing and unsustainable practices, as some marine collagen products use shark skin. In contrast, our bovine collagen is sourced from Swiss farms that ensure high standards of animal welfare. These farms guarantee no growth hormones and zero exposure to glyphosate. This approach allows us to provide a traceable, responsibly-sourced product.

Bovine collagen offers a sustainable choice, as it is derived from cowhides, which are also used in industries like leather production, making it a more environmentally efficient choice. In contrast, marine collagen production often requires fish scales, which are not commonly used in other industries, potentially leading to resource inefficiencies.

At WillPowders, we recommend our bovine collagen as a sustainable, ethically sourced, and highly versatile supplement. While both marine and bovine collagen offer beneficial amino acids, bovine collagen may offer a broader range of support, potentially benefiting everything from skin and bone health to muscle and organ function. Marine collagen, though similar in structure, may be less suited for sustainable production and may contain additives that could impact gut health.

If you choose marine collagen, be sure to research its sourcing, sustainability practices, and possible effects on gut health. For a versatile collagen that aligns with sustainability and provides a complete amino acid profile, we’re proud to offer our grass-fed Swiss bovine collagen as an ideal choice.
