What is the difference between Sophie collagen peptide and other brands?

Sufi Ziguang Double Needle Collagen Peptide adopts marine fish collagen, which is deeply hydrolyzed by enzyme. The main raw materials that are pure, safe and pollution-free have been patented. Violet double needle is a truly selected small molecule! "Double needle" packaging, with "double peptide" as the core raw material, combines short peptide and "two-dimensional" compound formula to help users enrich high-quality collagen and stimulate their own collagen synthesis. These three characteristics deserve your in-depth look.
