Collagen

Collagen is the structural protein that makes up roughly a third of the body's total protein content — the connective scaffold of skin, bones, tendons, cartilage, and blood vessels. From age 25 onwards, endogenous collagen production gradually declines, and supplementation with hydrolysed collagen peptides has become one of the most commercially significant categories in nutricosmetics globally.

For private-label brands, the formulation reality is that meaningful collagen doses (2.5–10 g per serving) don't comfortably fit in a 2.5 g gummy. DAT's working approach for collagen-gummy ranges is to use collagen as a supporting active within a beauty stack — typically co-formulated with Vitamin C, biotin, zinc, and vitamin E — and to direct full-dose collagen positioning to sachet or doypack formats. This shapes both the formulation strategy and the pack-copy strategy: the claim hook in EU-market gummies is Vitamin C's authorised collagen-formation wording, not collagen itself.

Origin and history

Collagen as a substance has been part of food culture for centuries in the form of gelatine — a partially hydrolysed collagen produced from animal connective tissue and used in stocks, broths, jellies, and confectionery. The scientific characterisation of collagen as a triple-helical protein with a repeating glycine-proline-hydroxyproline motif was achieved through X-ray crystallography in the 1950s-60s (Ramachandran, Crick, Rich).

Hydrolysed collagen for supplement use is produced by enzymatic breakdown of collagen-rich raw material (typically bovine hide, fish skin and scales, or chicken cartilage) into low-molecular- weight peptides — usually 2,000–5,000 daltons. These peptides are small enough to be absorbed across the intestinal epithelium intact or as di- and tri-peptides, which differentiates supplement-grade hydrolysed collagen from dietary gelatine. Patented peptide brands (Verisol®, Peptan®, Naticol®, etc.) refer to specific molecular- weight ranges and clinical-trial datasets supplied by the raw- material manufacturer.

Scientific overview

Collagen is composed of three polypeptide chains wound in a triple helix, stabilised by hydroxyproline and hydroxylysine cross-links. Type I collagen dominates skin, bone, tendon, and most connective tissue; Type II is found in cartilage; Type III is present alongside Type I in skin and blood vessels. Hydrolysed collagen supplements typically deliver Type I and III (from bovine hide or fish skin) or Type II (from chicken cartilage, for joint-focused positioning).

When hydrolysed collagen is consumed, the peptides are absorbed either intact or after further digestion into di- and tri-peptides and free amino acids. Specific peptides such as Pro-Hyp and Hyp-Gly appear in circulation after oral collagen ingestion, and in-vitro research suggests these peptides act as signalling molecules to fibroblasts and chondrocytes, potentially stimulating collagen synthesis. Several randomised controlled trials in human subjects have reported improvements in skin elasticity, hydration, and joint comfort at doses of 2.5–10 g/day across 8–24 weeks of supplementation. EFSA, however, has not authorised specific health claims for collagen under Regulation 432/2012 — the body of evidence is considered insufficient under the current substantiation framework.

For the practical purpose of gummy formulation, the key constraint is dose-per-piece. A 2.5 g gummy can deliver up to ~500 mg hydrolysed collagen without compromising texture — well below clinical-trial doses. Brands sometimes position multi-piece daily servings (4–6 gummies per day) to approach 2 g, but this conflicts with consumer expectation of one-or-two gummies per serving. Sachet and doypack formats deliver 5–10 g per serving and are the strategically appropriate route for collagen-led claim positioning.

Collagen is one of the most commercially understood beauty actives across EU and US markets, and its inclusion in a gummy range — even at sub-clinical dose — carries strong consumer signal-value. The typical brief is a beauty stack: collagen alongside Vitamin C, biotin, zinc, vitamin E, and sometimes hyaluronic acid. In this configuration the substantiated claim hook is Vitamin C's authorised wording for collagen formation; collagen itself contributes to the perceived benefit and the on-pack positioning but does not carry an authorised claim of its own.

From a formulation standpoint, hydrolysed collagen is straightforward to work with at low dose. It is heat-stable, soluble in the sugar syrup at cook stage, and contributes minimal taste at <500 mg per gummy. Marine collagen requires mandatory 'fish' allergen labelling in the EU; bovine and chicken sources do not, but raise vegan / kosher / halal considerations that are confirmed per project and batch. Patented peptide brands command higher cost and require licence agreements with the raw-material supplier — DAT handles this case-by-case in project workspace.

For pack-copy, brand owners should avoid 'collagen rebuilds skin' or 'reverses wrinkles' language; these are not authorised claims under Reg. 432/2012, and standalone collagen claims are not currently substantiated under the EFSA framework. The acceptable approach is to make claims attributable to Vitamin C (the substantiated nutrient for collagen formation) while positioning the overall product within the beauty category. DAT reviews final pack copy per project against the authorised list before production.
