Does the supplement not just get digested as it's a protein?Updated 9 months ago

This is a common misconception. 

Traditionally it was thought that all protein is broken down and digested in the same manner. However, in recent years, more and more studies have been conducted with scientific evidence showing this to be untrue. 

In fact, after ingestion, collagen peptides have been shown to resist peptidase digestion and are absorbed into the blood circulation system at relatively high levels.

Peptides derived from marine collagen help with the formation of collagen by stimulating fibroblast growth and encouraging the production of extracellular matrix components, meaning it stimulates your own system into creating collagen. 

Numerous studies have concluded that the absorption rate of liquid marine collagen by the human body is as high as 95%-98%, but will vary from person to person.
