The Science of Seanol®

Seanol® isn't just another supplement ingredient. It's a patented marine compound extracted from Ecklonia cava — a rare brown seaweed harvested from the clean coastal waters of South Korea. Backed by decades of research, 18 clinical trials, and regulatory approval in the USA, EU, and Korea, Seanol® works at a cellular level to protect, restore, and support the body in ways no land-based antioxidant can match.
Where does Seanol® come from?

Seanol® is extracted from Ecklonia cava, a species of brown seaweed found exclusively in the deep coastal waters off South Korea. Unlike most antioxidant ingredients sourced from land-based plants, Ecklonia cava has evolved in a harsh marine environment — developing a uniquely powerful class of polyphenols called phlorotannins that far outperform their land-based counterparts.

What are phlorotannins?

Phlorotannins are the active compounds in Seanol® responsible for its health benefits. Think of them as the seaweed's natural defence system — built to fight oxidative stress, inflammation, and cellular damage. What makes them special is their structure: they are soluble in both water and fat, meaning they can penetrate cell membranes and even cross the blood-brain barrier — something most antioxidants cannot do.

How does Seanol® compare to other antioxidants?

Most antioxidants — green tea, grape seed, vitamin C — are water soluble only, limiting where they can work in the body and how long they last. Seanol® is different. Its dual solubility means it remains active in the body for up to 12 hours, compared to just 3–4 hours for green tea or berry polyphenols. Its antioxidant strength is also significantly higher — with an ORAC value of 8,368 μmol TE/g and potency reported at 230x stronger than Vitamin E.
