- Different collagen sources offer distinct advantages:
- Marine collagen from fish skin and scales provides predominantly Type I collagen with small molecular weights (2,000-5,000 Daltons). It may offer superior bioavailability and is sustainable when sourced from fishery byproducts. However, it costs more than bovine alternatives.
- Bovine collagen from grass-fed cattle provides Types I and III collagen. It is widely available, cost-effective, and backed by extensive research. The cellulite study used porcine (pig) derived collagen, which has similar properties to bovine.
- Chicken collagen is primarily Type II, focused on joint health rather than skin. It is less relevant for cellulite treatment.
- Plant-based alternatives cannot provide actual collagen as plants do not produce it. Vegan products contain amino acids or plant peptides that may support collagen production, but lack direct evidence for cellulite reduction.
- For cellulite specifically, bovine or marine collagen containing Types I and/or III with molecular weights under 5,000 Daltons represents the evidence-based choice.
