If you’ve been wondering what all the fuss is about marine collagen, you’ve come to the right place.

As more and more research emerges, we’re learning that compared to other types of collagen, marine collagen peptide powders  are more bioavailable and friendlier to the environment. And this is all while doing great things for your skin health, joints, and hair—it’s basically the fountain of youth, in powder form. 

In this post, we’ll walk you through the emerging science and potential benefits of marine collagen. We’ll also compare marine collagen peptides to bovine collagen and answer your biggest questions about marine collagen. (Already a collagen fan?

But what the heck is collagen to begin with, you say? Collagen is an important protein present in your skin, bones, tendons, intestines, muscles, and other tissues in your body. It’s the most abundant protein in your body, providing structure and helping your body function. Without collagen, everything from your cheeks to your knees would be as dry and inflexible as a piece of chalk. (Like a skeleton... AKA, you’d be dead).
