Hey Jajaj,
Collagen isn’t like most supplements.
Your body doesn’t just absorb it and put it to work.
It has to rebuild it.
Here’s what I mean:
When you take collagen peptides, your body breaks them down into amino acids—specifically glycine, proline, and hydroxyproline—the raw materials your connective tissue is built from.
But here’s the part most collagen products are missing:
Your body can only assemble those amino acids back into new collagen if specific cofactors are present.
Vitamin C is the most critical one.
It’s directly required for the enzymatic process that stabilizes collagen’s structure—without it, the assembly process stalls.
Biotin plays a supporting role too, particularly for the keratin-based tissues collagen works alongside—your hair and nails.
Most collagen powders on the market give you the raw material.
But they leave out the tools your body needs to use it.
That’s one of the first things I changed when I formulated Dr. Berg Multi Collagen Peptides.
Each serving includes 90 mg of vitamin C and 60 mcg of biotin alongside 15.5 grams of collagen peptides—so your body has both the raw material and the cofactors it needs to put that collagen to work.
But there’s a second problem most people run into.
Not all collagen is the same.
Your body contains 28 different types of collagen, each playing a specific structural role in different tissues.
Type I: The most abundant and the primary structural collagen in your skin, tendons, ligaments, and bones
Type II: Is concentrated in cartilage, where it cushions and supports your joints
Type III: Forms the soft, flexible networks in your blood vessels and internal organs
Type V: Helps regulate how collagen fibers organize themselves in your skin and connective tissue
Type X: Supports cartilage and bone matrix development
Most single-source collagen supplements only give you one or two of these types.
That means if joint comfort, mobility, or connective tissue resilience is part of why you’re taking collagen, a single-type formula may not be covering the tissue that needs it most.
Dr. Berg Multi Collagen Peptides includes all five types, sourced from
