Collagen peptides are extracted from natural collagen. As a functional raw material, they are widely used in food, beverage and dietary supplement products, bringing benefits to bone and joint health and skin beauty. At the same time, collagen peptides can also speed up the recovery from training of the sports enthusiast or professional athlete. Scientific research has confirmed that collagen peptides, when taken as a dietary supplement, can simultaneously accelerate cell regeneration and growth in the human body, and the theoretical basis for the biological mechanism behind these health benefits is gradually taking shape.
The two most directly related to these health benefits are bioavailability and bioactivity.
What is bioavailability?
Nutrients in food are first broken down into small molecules and further digested in the gut. When some of these molecules are small enough, they can be absorbed through a specific route through the intestinal wall and into the bloodstream.
Here, what we mean by bioavailability refers to the body's availability of nutrients in food and the degree to which these nutrients are "separated" from the food matrix and transferred into the bloodstream.
The more bioavailable a dietary supplement is, the more efficiently it can be absorbed and the more health benefits it can deliver.
That's why bioavailability is critical for any nutritional supplement manufacturer - a dietary supplement with poor bioavailability has little added value to consumers.
What is biological activity?
Biological activity refers to the ability of a small molecule to modulate the biological function of a target cell and/or tissue. For example, a biologically active peptide is also a small fragment of a protein. During digestion, the peptide needs to be released from its parent protein for biological activity. When the peptide enters the blood and acts on the target tissue, it can exert a special "biological activity".
Bioactivity makes nutrients "nutritious"
Most of the nutrients we know, such as protein peptides, vitamins, are biologically active.
Therefore, if any manufacturer of nutritional supplements claims that their products have functions such as bone and joint health, skin beauty or sports recovery, etc., they need to prove that their raw materials can indeed be absorbed by the body, remain biologically active in the blood, and reach target organization.
The health benefits of collagen peptides are well known and numerous studies have confirmed their effectiveness. The most important health benefits of collagen peptides are related to its bioavailability and biological activity. These two are the most important influencing factors for health efficacy.
