SEAPOLYNOL®: Registered trade name of Botamedi Inc that represents a dietary ingredient with 90+% phlorotannins (rich in various eckols) extracted from Ecklonia cava . In 2008, US FDA authorized Botamedi's SEAPOLYNOL® (a.k.a.,SEANOL®-P) as a new dietary ingredient (NDI). In 2018, European Food Safety Authority (EFSA) reconfirmed its safety and EU authorized it as Novel Food Ingredient (NFI).

Another name of SEAPOLYNOL®, a dietary ingredient with 90+% purity phlorotannins extracted from Ecklonia cava .


Polyphenols occuring only in brown algae with distinct oligomeric/polymeric structures only based on phloroglucinol (1,3,5-trihydroxybenzene).


These molecules were isolated and identified by chemists in the early 1980's to be unique polyphenols later called "eckols". Since late 1980's up to present, hundreds of health-supporting scientific evidences of eckols have been discovered.

Sea polyphenol(s), marine polyphenol(s)
