Collagen Types, Explained: I, II, III, V & X

Collagen isn't one thing — it's a family of proteins, and different types come from different sources and are generally associated with different parts of the body. Our Collagen Belly Burn formula blends five types (I, II, III, V and X) from four distinct sources, so it's worth breaking down what each one is.

Type I — the most abundant

Type I is the most common collagen type in the body, found in skin, tendons and bone. In our formula it comes from grass-fed bovine and wild-caught Alaskan fish.

Type II — joint cartilage

Type II is primarily found in cartilage. We source ours from cage-free chicken bone broth.

Type III — often paired with Type I

Type III is commonly found alongside Type I in skin and blood vessels, and is also sourced from grass-fed bovine in our formula.

Types V & X — structural and specialized

Types V and X play more specialized structural roles. In Collagen Belly Burn, they're sourced from avian eggshell membrane.
