Histamine Tracker
Kelp/Seaweed
Seaweed may contain moderate histamine levels that vary significantly depending on the type, processing, and how long it's been stored.
Seaweed is a broad category, and histamine content can shift considerably depending on species, drying method, and storage time.
-
Freshness and processing — dried and packaged seaweed that's been sitting a while may have higher histamine levels than freshly harvested; storage conditions matter a lot here
-
Type variation — kelp, nori, wakame, and dulse all behave differently; some people with histamine sensitivity report tolerating certain types better than others
Checking packaging dates and opting for freshly processed varieties when possible may help.
