Over 90% of global carrageenan output is sourced from cultivated Eucheuma and Kappaphycus species. This makes the warm-water red algae, Kappaphycus alvarezii, the primary species used for producing refined carrageenan, specifically the kappa-type. Other red seaweeds, including *Eucheuma denticulatum*, are also important sources for different types of carrageenan.
