Origin of SEANOL®

SEANOL® is a registered trade name of Botamedi Inc and Simply Healthy Inc that represents dietary phlorotannins of brown algae.


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 so special about these places?

Over the years, scientists have found explanations for those seemingly magical places. 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 that provides shelter and nourishment.

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 of the sun, as well as undersea viruses and bacteria.


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

Industrial-scale Production

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

NDI AUthorized

In 2008, the 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).

NFI AUthorized

In 2017, the uropean Food Safety Authority (EFSA) thoroughly reviewed SEAPOLYNOL® and confirmed its safety. Accordingly in 2018, the 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

How can brown algae flourish in the virus-rich sea?

Since 170 million years ago upto the present, brown algae have been flourishing in the presence of various harmful viruses, thanks to their superb anti-viral phytochemicals which are super toxic to viruses but not at all to their own cells. .

Polyphenols and Polysaccarides, potent and wide-scope antiviral agents.

These natural chemicals have been discovered by scientists and identified to be sea polyphenols and polysaccharides, and have shown potent and wide-scope antiviral effects for various virus types, host species and modes of action.

Stop COVID-19

Anti V is a combination of highly purified sea polyphenols and polysaccharides of edible brown algae that have shown highly active and wide-scope antiviral activities in peer-reviewed published scientific studies
