Collagen is a protein that serves as one of the main building blocks for the bones, skin, hair, muscles, tendons, and ligaments.

Collagen is mainly composed of three amino acids – proline, hydroxyproline, and glycine. Each of these molecules gives collagen specific chemical and biochemical properties, making it the most prevalent and important protein in the body.

Collagen peptides (collagen hydrolysate) are shorter versions of collagen that can be found in protein powders. These molecules are made by the breakdown of full-length collagen, but they maintain the same amino acid composition.

Contrary to full-length collagen, these compounds can be absorbed by the digestive tract to travel in the bloodstream and provide constructive and protective benefits.

The major difference between collagen and collagen peptides is bioavailability.

Full-length collagen cannot get absorbed in the digestive tract because of its length and spatial conformation. Therefore, it’s less effective as an oral supplement.

On the other hand, collagen peptides are more bioavailable since they get easily absorbed into the bloodstream because of their shorter structure.

As we age, our bodies produce less collagen, which may lead to elasticity and hydration problems, resulting in wrinkles and skin dehydration.

In a clinical study, researchers analyzed the effects of collagen supplements on skin elasticity and moisture. 69 participants were divided into three groups, with one group receiving 2.5-5 grams of collagen over a course of 8 weeks.

At the end of the study, scientists noticed a significant improvement in skin elasticity, hydration, and appearance compared to the control group.
