A study on the knowledge and attitudes of dietitians and their clients about collagen

Abstract

This study aimed to assess the opinions of dietitians and their clients regarding their knowledge and use of collagen and to determine their level of knowledge regarding the use of collagen supplements. It was conducted on 30 dietitians and 125 clients in Istanbul, Balıkesir, Antalya and Hatay provinces between March and April 2023. Online data was collected from participants via Google Forms. 56.7% (n=17) of dietitians and 54.4% (n=68) of their clients use collagen (P>0.05). While 36.7% (n=11) of dietitians said, it was beneficial for the skin, 23.3% (n=7) used it for weight control and digestive regulation, 38.4% (n=48) said it was beneficial for the skin and 34.4% (n=43) for joint density and pain relief. There was also no statistically significant difference (P>0.05) between dietitians' and clients' information about collagen use. However, while 17.5% (n=3) of dietitians were concerned about the reliability, certification, and brand of collagen, 22.1% (n=15) of consumers were concerned about its reliability. In addition, the opinions of the dietitians and clients participating in the study regarding the use of collagen were not found to be statistically significant (P>0.05).
