Collagen is the most abundant structural protein in the human body, and collagen peptides have become one of the best-selling supplement categories of the last decade. For OEM buyers, the category is attractive because demand is broad — beauty-from-within, active lifestyles and healthy aging all feed it — and because the supply chain, from raw material to finished format, is well established. Here is what collagen peptides are and the decisions to settle before you launch.

What are collagen peptides?

Collagen is a family of proteins found in connective tissues. In supplements, it is almost always sold as hydrolyzed collagen peptides: collagen that has been broken down by enzymes into smaller, water-soluble peptide chains that are easier to use in foods and beverages.

Sourcing matters. Collagen peptides come from bovine (cow hide), marine (fish skin and scales) or avian sources, and the type differs by source — Type I and III are typical of bovine and marine collagen, while Type II is more associated with cartilage-focused products. Marine collagen is often preferred for clean, pescatarian-friendly positioning, while bovine collagen is the workhorse for cost-effective, high-volume lines.

Which format should your brand choose?

Collagen peptides are unusually format-flexible, which is one reason the category keeps growing:

  • Powders — the classic format: unflavored peptides dissolve in coffee, water or smoothies; flavored versions are also popular.
  • Gummies — the fastest-growing format for beauty positioning. Note that collagen is animal-derived, so gummies are typically made with a gelatin or marine-collagen base; a fully vegan collagen gummy is not possible unless you use a vegan alternative such as silica or a vegan collagen builder.
  • Oral liquids and shots — premium positioning, easy to pair with hyaluronic acid, vitamin C and other beauty ingredients.
  • Capsules — convenient but limited by dose per serving, since collagen is dosed in grams.

Many brands launch a powder or gummy first, then extend into liquids once the audience is proven. For gummies specifically, the typical challenge is dose: collagen is dosed in grams, so a gummy line must balance a meaningful peptide content with a practical piece size — a formulation conversation your OEM partner should lead.

Formulation decisions to settle

  • Dose per serving. Collagen is typically consumed in gram-level servings; confirm the target grams per serving and how many pieces or scoops that means.
  • Molecular weight. Hydrolyzed peptides with a low molecular weight are the industry standard for solubility and mixability — ask your supplier for the specification.
  • Source and label claims. Bovine, marine or avian; grass-fed, wild-caught or halal/certified options change the label story and the price.
  • Companion ingredients. Vitamin C, hyaluronic acid, biotin and zinc are frequent partners in beauty-positioned formulas.
  • Flavor and texture. Collagen has a mild taste, but gummies and liquids still need a flavor system that fits your brand.

Compliance and documentation

Collagen peptides are a conventional food ingredient in most markets, which makes compliance comparatively straightforward — but labeling rules still apply. Keep claims structural rather than medical: describe the role of collagen as a protein in the body's connective tissues, and avoid language about diagnosing or managing conditions. If you sell into the United States, an FDA facility registration is an establishment listing, not a product approval — it confirms the manufacturing site is registered, and it is not a statement about your finished product.

What a buyer should verify with any supplier: GMP-compliant production, a COA with every batch covering identity, assay, heavy metals and microbiological limits, source documentation for the collagen type you ordered, and export paperwork for the destination market.
