What Research Shows
May Be Effective
Editorial process and description of evidence categories can be found at EBSCO NAT Editorial Process.
It is likely safe for most adults who are not allergic to shellfish to take green-lipped mussel for a short time. Not enough studies have been done to say whether it is safe to take for a long period or during pregnancy or breastfeeding. Green-lipped mussels may be contaminated with a harmful parasite.D2
