Moderate. May need monitoring, a dose adjustment, or separating the times you take each one.
Minor. Generally not clinically significant, but still worth noting and mentioning to your pharmacist.
No known interaction. Checked against our sources with nothing documented — not the same as proven safety.

Likelihood — How Well It’s Documented

Probable. Interaction has not been documented in well-controlled studies, however, the interaction has been demonstrated in some small human studies or in controlled animal studies in conjunction with multiple case reports.
Possible. Interaction has been documented in animal or in lab research, or the interaction has been documented in humans but is limited to case reports or conflicting clinical research exists
Unlikely. Interaction has been demonstrated in animal or in lab research but has been shown not to occur in humans.

Overview

New Zealand green-lipped mussel is a shellfish that grows in the coastal waters around New Zealand. It gets its name from the green color along the edge of its shell. The mussel has long been part of the traditional diet of the Māori people, and researchers noticed that coastal communities who ate a lot of it seemed to have fewer joint problems.

For supplements, the mussel flesh is usually freeze-dried into a powder or processed into a fat-rich (lipid) extract. These are sold as capsules, softgels, tablets, and powders. The supplement is most often marketed for joint health and inflammation.

How it works

Green-lipped mussel contains omega-3 fatty acids, including some unusual fats not commonly found in fish oil. It also contains proteins, minerals, and compounds linked to cartilage support such as glycosaminoglycans.

The leading idea is that these omega-3 fats and other compounds may help calm inflammation in the body, which could ease joint pain and stiffness. Much of this understanding comes from laboratory and animal studies, so it is not fully proven in people. The exact active ingredients responsible for any benefit are still not clearly identified.
