Why It's Confusing
Collagen has been repositioned as a wellness ingredient in cafés, smoothie bars, hotel spas, and in-flight menus. The marketing language, "beauty from within," "plant-based collagen boost", frequently obscures the source.
"Vegan collagen" typically refers to collagen builders (vitamin C, amino acids, hyaluronic acid) that support the body's own collagen production [[3]](#source-3). They do not contain collagen. "Marine collagen" is sometimes labelled pescatarian-friendly but is still animal-derived [[1]](#source-1). The same outer capsules are usually gelatin, and dairy-protein supplements often rely on casein.
Where It Commonly Appears
- Smoothie and juice bar add-ons at wellness cafés
- Hotel breakfast supplement stations
- In-flight wellness menus (premium cabins)
- Protein and beauty powders on retail shelves
- Capsule supplements, the outer capsule itself is often gelatin
- Topical skincare (creams, serums, sheet masks)
What To Watch For
- Bovine collagen, porcine collagen
- Marine collagen
- Hydrolysed collagen, collagen peptides
- Distinguish "plant-based collagen builder" from "collagen", they are not the same product
Vegan Alternatives
- Collagen-supporting (not collagen-containing) products: vitamin C, biotin, silica, hyaluronic acid, amino acid complexes
- Brands: Moon Juice [[3]](#source-3), Ora, Sunwarrior
