How is hydrolyzed collagen absorbed by the body?

Why are collagen supplements recommended if it can be found in our diet? The answer lies in our body’s absorption ability. Let’s talk about science!

In order for our body to absorb the different nutrients and amino acids contained in the food that we eat, multiple processes are triggered, starting as early as chewing, to break down their complex molecular structures.

From chewing to the blood stream

Complex food molecules are reduced to their simplest expression by traveling through our digestive system, from the stomach to the small intestine, passing from non-assimilable molecules to separated amino acids that are used and recombined by our body, according to our specific needs.

Chloridric Acid and Pepsin initiate protein structure transformation at the stomach level. These two elements’ mission is to simplify the complex molecular structure into a long chain of amino acids which will be more accessible to enzymes which will then unravel their links and begin to isolate them.

The mixture of chained amino acids and isolated amino acids will then travel to the pancreas and to the small intestine where other enzymes will continue to isolate the amino acids for maximum absorption and efficiency.

Once in the small intestine, amino acids are absorbed through various channels and directed through the bloodstream where they are used and reassembled as needed by the body.

Science claims that the body absorbs roughly 15% of amino acids from collagen in our food while it absorbs up to 90% of hydrolyzed collagen ingested as a supplement. A difference which is not negligible!

A study by Oesser, estimates that approximately 90% of hydrolyzed collagen administered orally is absorbed within 10 hours of gastrointestinal ingestion while as much as 47% is absorbed within the first hour of ingestion.

Overall, between 85% and 95% of hydrolyzed collagen is assimilated.

Additionally, studies have shown that hydrolyzed collagen shows better absorption when ingested in a liquid form where amino acids are separated into smaller parts and since vitamin C is also essential for the natural synthesis of collagen in the body. Thus using hydrolyzed  collagen in combination with  natural vitamin C supplements proves to be even more effective.
