Fish Collagen Peptide Food Supplement on Weight and Body Composition

Effect of a Fish Collagen Peptide Food Supplement on the Weight and Body Composition of Healthy Volunteers in Overweight

Fish collagen hydrolysates or peptides orally administered have been investigated in recent clinical trials in human health. These peptides have been evaluated in various biological and medical fields including skin aging, osteoarticular apparatus, muscle and more recently in energy metabolism in both animals and humans.

However, very few studies investigated the effect of fish collagen peptides on weight, body composition or glycemic response. Recently, it has been shown that the consumption of fish collagen peptides (Naticol®) limits weight gain and increase in fat mass in a mouse model made obese by a hyperlipidic diet. Since these results have never been observed in humans, this pilot study proposes to answer this question.
