Collagen is the most abundant protein in the body, and its peptide chain structure gives it unique physical and chemical properties. It mainly maintains tissue structure and functional integrity by interacting with the extracellular matrix. When collagen is damaged or decomposed, it can lead to decreased skin elasticity, joint stiffness and other phenomena. Due to the lack of collagen peptides or synthesis disorders, problems such as loose skin, sparse hair, and brittle nails may occur. In addition, symptoms such as joint pain and limited movement may also occur.

In the case of collagen peptide deficiency, amino acid analysis in the blood and hydroxyproline level detection in the urine can be performed. The former can evaluate the amino acid metabolism state, while the latter directly reflects the collagen metabolism in the body. Supplementing health products containing collagen may be one of the effective treatments. For example, oral vitamin C can help promote collagen synthesis, while using skin care products containing hyaluronic acid can help improve the skin's ability to retain moisture.

To support the health of collagen peptides, it is recommended to increase the intake of foods rich in antioxidants, such as dark vegetables and berries, to reduce the damage of free radicals to collagen.
