Landish marine collagen is made from the skins of wild, deep-sea ocean fish. This provides a different amino acid profile than bone broths, which are typically made from the bones and connective tissues of animals (mostly chicken or beef). There are a few differences between the two types of collagen sources.
One difference is that Landish marine collagen undergoes a process called hydrolysis, a clean, enzymatic process that involves breaking the collagen down to more digestible collagen peptides for maximum bioavailability and effectiveness. Collagen protein in the form of gelatin, such as bone broth, has not been broken down into peptides and is, therefore, much harder for the body to absorb and use to synthesize collagen in the body.
Another difference between the two types of collagen is their amino acid profile. One study showed that the amino acid concentrations in bone broth were significantly lower in several key amino acids (glycine, proline, hydroxyproline, lysine, hydroxylysine, and leucine) than collagen supplements, which were shown to provide a more consistent amino acid profile (1).
