Marine vs Bovine: How To Pick the Right Collagen For You

Collagen is a protein that’s essential to your bones, cartilage, skin, and other tissues. It’s a total game-changer for your health and well-being, so let’s talk a bit more about the source of these two types of collagen. Marine collagen is sourced from the skin, bones, and scales of fish, while bovine collagen comes from cows’ skin, bones, and cartilage. Both types contain types I, II, and III collagen, but they differ in amino acid composition, making them unique.

Now, let’s get into the benefits. Collagen has a ton of potential health benefits, such as improving your skin’s health, promoting joint health, and reducing inflammation. If you’re a gym-goer, you’ll be thrilled to hear that it can also support muscle growth, and for those of you who struggle with digestive issues, collagen can help there too!

Here’s where things get interesting – the bioavailability of these two types of collagen differs. Marine collagen has a lower molecular weight, which means it’s more easily absorbed by your body. Bovine collagen, on the other hand, has a larger molecular weight, making it less bioavailable.

Another factor to consider is the potential for contaminants. Marine collagen has a lower risk of contamination, making it a safer option for folks with allergies or sensitivities. In contrast, bovine collagen can be exposed to pesticides and hormones used in the production process, which may not be ideal for some individuals.

So, what’s the verdict? Both types of collagen offer potential health benefits, but they differ in bioavailability, source, and potential contaminants. While our doctors recommend choosing marine collagen over bovine collagen, it’s essential to consider all these factors as well as your priorities when choosing which collagen supplement is right for you. As always, we strongly encourage consulting with a healthcare professional before starting any new supplement regimen!
