All excellent points above! Just to summarize:
Bovine (Cows) – Best for Types I & III collagen, great for joint and skin health. Usually the most cost-effective.
Marine (Fish) – Mostly Type I, highly bioavailable, great for premium beauty supplements.
Porcine (Pigs) – Very close to human collagen, widely used in medical and some food apps, though less popular in mainstream dietary supplements due to dietary restrictions.
Poultry (Chicken cartilage) – Usually Type II collagen, specifically targeted for joint health formulas.
If you’re looking for raw materials for manufacturing, you just need to match the source to your target audience’s budget and dietary needs.
