do collagen peptides help with weight loss?

From a compliance perspective, I need to warn brand owners: do NOT use the phrase “weight loss” on your packaging unless you want an FDA warning letter.
Dietary supplements cannot claim to treat obesity or cause direct weight loss. Instead, you should position your collagen products around “healthy weight management” or “supporting healthy body composition.” You can legally state that it “promotes satiety” or “supports lean muscle mass,” which appeals to the exact same demographic without crossing regulatory lines.
