Collagen peptides are generally not considered as IQ tax. Collagen peptide is the product of collagen through biological enzymatic digestion, can be better absorbed by the body. Collagen is rich in glycine, proline, hydroxyproline and other amino acids needed by the human body. Collagen is an important part of the extracellular matrix, which contributes to the formation of bones. For certain people with relatively poor absorption function, collagen peptides can be chosen to facilitate the body’s absorption, and will not increase the burden on the digestive tract, so collagen peptides are not considered an IQ tax. However, it should be noted that there are more false advertisements about collagen on the market, exaggerating its efficacy, patients should not blindly follow the trend, and should be careful to buy. If you want to buy, it is recommended to choose products produced by regular manufacturers and certified by the State Food and Drug Administration.
