Marine collagen is a type of collagen that is derived from the skin and scales of fish, while bovine collagen is derived from the skin, bones, and muscles of cows. Both types of collagen have gained popularity as supplements due to their potential health benefits, but recent studies suggest that marine collagen may be the better option.

One of the primary reasons why marine collagen may be better than bovine collagen is its bioavailability. Bioavailability refers to the extent to which a substance can be absorbed and utilized by the body. Studies have found that marine collagen has a smaller molecular weight than bovine collagen, which makes it easier for the body to absorb and utilize.

In fact, one study found that marine collagen was absorbed up to 1.5 times more efficiently than bovine collagen, which suggests that marine collagen may be more effective at promoting skin health, joint health, and overall well-being.

Another factor that sets marine collagen apart from bovine collagen is its amino acid profile. Collagen is made up of several amino acids, including glycine, proline, and hydroxyproline. While both marine and bovine collagen contain these amino acids, the ratio of amino acids in marine collagen is closer to the ratio found in human collagen.

This means that marine collagen may be more effective at promoting the production of collagen in the body. In particular, marine collagen has been shown to increase the production of type I collagen, which is the most abundant form of collagen in the human body and is essential for maintaining healthy skin, bones, and joints.

Sustainability is another important factor to consider when choosing a collagen supplement. Bovine collagen is often sourced from cows raised for food, which can have negative environmental impacts such as deforestation, water pollution, and greenhouse gas emissions.

On the other hand, marine collagen is sourced from fish that are often caught as part of sustainable fishing practices, which can help to protect marine ecosystems. This makes marine collagen a more environmentally friendly option compared to bovine collagen.

While both bovine and marine collagen can provide benefits for the body, marine collagen may be the better option. Marine collagen has a higher bioavailability, a more beneficial amino acid profile, and is more sustainable than bovine collagen.

If you're looking to add a collagen supplement to your diet, it's important to choose a high-quality product that is sourced from sustainable and ethical sources. As always, it's important to consult with a healthcare professional before adding any supplements to your diet.
