Origin of SEANOL®


SEANOL® is a registered trade name of Botamedi Inc (new corporate name of "Livechem Inc" since 2012) and Simply Healthy, LLC that represents dietary phlorotannins of brown algae.


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). Therefore, in the US and EU, SEAPOLYNOL® is only Ecklonia cava extract (or Ecklonia cava phlorotannins ) that is legally traded in the dietary supplement market.


The source of phlorotannins is a place where mystery and science come together, the ocean. For centuries the ocean held a secret known only to a few fortunate divers. There are places where exotic fish seem almost to cavort in the sea, playing and dancing with delight and energy not seen in other parts of the ocean. For decades, marine ecologists studied this intriguing but highly localized phenomenon. What was it about these places?

Sciencific Explanation

Scientists found that those seemingly magical places have a scientific explanation. These locations are literally underwater forests of certain types of brown algae characterized by thick golden leaves waving vigorously with the currents. Not surprisingly, the fish find there an ideal habitat providing shelter and nourishment.

Unique Discovery

But the truly unique discovery of these special places is that as the currents rhythmically sway the golden marine leaves, they release minute amount of certain molecules into the surrounding water. These unique, and completely natural molecules, protect the nearby life forms from harsh ultraviolet rays from the sun.


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.

Industrial-scale Production

In 2005, a standardization and industrial-scale production of these special polyphenols from brown algae was realized for the first time by Livechem Inc (now, Botamedi Inc) and registered under the brand names "SeanolĀ®" and "SEAPOLYNOL®".

NDI Authorized

In 2008, US FDA authorized the use of the Ecklonia cava extract that meets the specification of Botamedi's SEAPOLYNOL® (a.k.a.,SEANOL®-P) as a new dietary ingredient (NDI). SEANOL®-F is an example of applying the new dietary ingredient SEAPOLYNOL® in a dietary supplement.

NFI Authorized

In 2017, European Food Safety Authority (EFSA) thoroughly reviewed SEAPOLYNOL® and confirmed its safety. Accordingly in 2018, EU authorized the use of Ecklonia cava extract that meets the specification of Botamedi's SEAPOLYNOL® (a.k.a.,SEANOL®-P)as a novel food ingredient (NFI)

Safety of Ecklonia cava phlorotannins as a novel food pursuant to Regulation (EC) No 258/97
