Cellgen™ Application Performance
Why peptide size
determines product outcome
Cellgen™ is hydrolysed to 500–2,000 Da — small enough to absorb intact, signal fibroblasts, and perform where generically processed collagen cannot. The molecular weight of a collagen hydrolysate is not a secondary specification. It is the primary determinant of what that ingredient can and cannot do in a formulation.
Cellgen™
500–2,000 Da — higher bioavailability
Generic Collagen
3,000–10,000+ Da — lower bioavailability
Application 01
Wellness Innovations
Bioavailability is the defining metric in nutraceutical formulation and molecular weight is its single greatest lever. Lower-Dalton collagen peptides bypass the need for full protease digestion in the gut, allowing intact bioactive sequences to be absorbed and transported to target tissues including cartilage, bone and connective tissue at relevant concentrations. Generically processed collagen depends on the individual's digestive efficiency, which declines with age, stress and gut imbalance — precisely the populations most likely to be taking a collagen supplement.
Application 02
Ingestible Beauty
For ingestible beauty applications, the collagen peptide size determines whether the product delivers a measurable dermal outcome or simply provides a protein contribution indistinguishable from any dietary source. Smaller peptides — particularly those in the sub-2,000 Dalton range — have demonstrated the ability to stimulate fibroblast activity and upregulate endogenous collagen synthesis in the dermis. The Pro-Hyp dipeptide, abundant in low-molecular-weight hydrolysates, is recognised as a key signalling molecule for skin collagen production.
Application 03
Functional Beverages
Beverage applications demand solubility, clarity and flavour neutrality — all of which are compromised by higher-molecular-weight collagen. Generic hydrolysates at elevated Dalton sizes frequently produce haze in cold liquids, resist full dissolution at lower temperatures, and can contribute an off-savoury note that limits formulation flexibility. The low viscosity (4–10 mPas) and spray-dried powder form of this specification means it dissolves cleanly in both hot and cold beverages, from RTD formats to functional waters, without affecting mouthfeel or clarity.
Application 04
Functional Foods
Collagen processed to 500–2,000 Da disperses readily in food matrices without gelling, clumping, or altering texture. In functional food formulation this matters enormously — a smaller peptide size means faster gastric transit, earlier absorption at the intestinal wall and a higher proportion of bioavailable dipeptides and tripeptides entering systemic circulation intact. Generic collagen hydrolysates processed to higher Dalton weights require more enzymatic breakdown in the gut before absorption can occur, introducing variability and reducing the guaranteed functional yield per serve.
Application 05
Skincare & Topicals
In topical formulations, molecular weight is the difference between a collagen ingredient that sits on the skin's surface and one that penetrates to the epidermis and upper dermis. The stratum corneum presents a significant barrier to larger molecules — peptides above approximately 3,000–5,000 Daltons cannot penetrate this layer through passive diffusion alone. Lower-Dalton collagen peptides in the 500–2,000 Da range can traverse the skin barrier to interact with dermal fibroblasts and stimulate matrix remodelling.
