Not all collagen supplements deliver the same results. The difference lies in three factors: source, manufacturing process, and molecular weight. Peptan® B 2000 LD leads on all three.
What Is Peptan®?
Peptan® is a bioactive collagen peptide developed by Rousselot, a French collagen manufacturer with over 130 years of expertise. It is not a generic ingredient — it is a precisely engineered, clinically validated product with a traceable supply chain and an extensive body of peer-reviewed research.
Why Bovine?
Bovine collagen is rich in Type I and Type III collagen — the types most present in human skin, hair, nails, and bones. It provides your body with the exact building blocks it needs to support these tissues.
Rousselot sources exclusively from traceable, GMP-certified suppliers. Most generic collagen manufacturers cannot say the same.
Why 2000 Daltons?
This is the critical differentiator.
Native collagen molecules weigh ~300,000 Daltons — too large to be absorbed. Most hydrolyzed collagens on the market sit between 3,000 and 10,000 Daltons.
Peptan® B 2000 LD is hydrolyzed down to 2,000 Daltons. Small enough to pass efficiently into the bloodstream, reach target tissues, and trigger real biological responses: collagen synthesis, fibroblast activation, antioxidant activity.
LD stands for Low Dispersity — meaning every batch delivers a consistent, predictable molecular weight. Generic collagens can’t guarantee this.
Clinically Studied
Peptan® is backed by 30+ peer-reviewed studies on skin elasticity, hydration, joint comfort, and muscle recovery. Most collagen products rely on general category research. Pearl Nutrition relies on data generated specifically on its ingredient.
What You’re Actually Getting
Pearl Nutrition contains one ingredient: 100% Peptan® B 2000 LD. No fillers. No additives. No blends designed to obscure what’s inside.
That’s what a clean label means in practice.
