The Science of Seanol®
Born in the ocean. Built for survival.
Ecklonia cava doesn't grow just anywhere. It anchors to the deep coastal waters of Jeju, South Korea — where intense ultraviolet light, salt pressure, and tidal force test every organism that survives there.
Over millions of years, this brown seaweed developed a defence chemistry that land plants never needed: a family of polyphenols called phlorotannins. They are the seaweed's own immune system — produced in response to oxidative stress. It's the same kind of stress our own cells face every day, from metabolism, UV exposure, and aging.
The quiet irony: the molecule that keeps a seaweed alive in the harshest marine environment is the same molecule that supports resilience in human cells.
The Seanol® Difference
Four properties set Seanol® marine polyphenols apart from anything found on land.
Dual Solubility
Soluble in both water and fat, Seanol® polyphenols travel through blood and penetrate cell membranes — where most land-based antioxidants do not reach.
Purified. Potent.
Purified to remove iodine, heavy metals and harmful substances, Seanol® marine polyphenols deliver potent antioxidant activity that supports the body's natural defences.
Detected in Brain Tissue
In preclinical research, Seanol® polyphenols have been detected in brain tissue, where they support antioxidant activity.
Potent Radical Scavenging
Laboratory studies demonstrate potent free-radical scavenging activity, helping neutralize the reactive oxygen species behind everyday cellular wear and tear.
What the research shows
Decades of published research and 18 clinical trials have mapped how marine polyphenols interact with the body’s major systems.
Antioxidant defense
Brain and eye cells are especially vulnerable to reactive oxygen species (ROS), which can compromise function over time. Sea polyphenols demonstrate exceptional antioxidative capacity — in laboratory studies they protect and stabilize cells, including neurons, against oxidative stress.
A healthy inflammatory response
Research indicates marine polyphenols support the body’s natural inflammatory balance by modulating key signaling pathways — including NF-κB and the COX/LOX enzyme systems involved in normal recovery and repair.
Brain & cognitive function
In preclinical studies, Seanol® polyphenols have been detected in brain tissue, where they support antioxidant activity. In animal studies, sea polyphenols supported memory — animals retained learned information for longer periods. This is the science behind iSeanol® Brain Supplement.
Eye health & screen stress
In a clinical study of the Seanol® Eye Drops formulation, tear production increased 84% and moisture retention lasted 67% longer, with effects observed within 5 minutes. Marine polyphenols also help shield the ocular surface from the oxidative stress of blue light (400–450 nm).
Skin & collagen support
Marine polyphenols help protect the skin’s structural proteins: they inhibit matrix metalloproteinases (MMPs) — the enzymes that break down collagen and elastin — and support the extracellular matrix through hyaluronic-acid binding. This is the mechanism behind DermaGel’s non-injectable skin booster and the Seanogen creams.
Muscle recovery & circulation
By supporting microvascular circulation, Seanol® polyphenols help deliver oxygen and nutrients to working tissues — supporting muscle recovery after exercise and healthy joint comfort. This is the science behind CelBon Body Cream and SLP8040 Marine Active Gel.
Hair & scalp vitality
The same polyphenols that protect skin cells support the scalp environment — helping maintain healthy follicles and a balanced scalp. This is the science behind the X10 Hair Renewal Solution.
The research behind the numbers
The same ingredient, the same evidence — across every Seanol® product.
18

25 years
of continuous research
Seanol® is one of the most studied marine polyphenols in the supplement category. This is a research record, not a marketing story: two and a half decades of published, peer-reviewed study, including 18 clinical trials conducted on Seanol® phlorotannins. The 33+ granted patents protect the extraction and formulation processes — which is why every batch is consistent, from Jeju to your shelf.
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. Through adaptation to a harsh marine environment, Ecklonia cava developed a unique class of polyphenols called phlorotannins with distinct structural properties compared to 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 — something most antioxidants cannot do.
How does Seanol® compare to other antioxidants?
Seanol® marine polyphenols exhibit dual solubility in both lipids and water, distinguishing them from many land-based antioxidants. Research indicates they demonstrate potent free radical scavenging activity in laboratory studies.
How is Seanol® extracted?
Seanol® is produced through a patented extraction and purification process that concentrates the phlorotannin fraction of Ecklonia cava while preserving its molecular structure.
Is Seanol® safe?
Seanol® has been notified to the US FDA as a New Dietary Ingredient, notified to the European Commission as a novel food, and certified as a Health Functional Food by Korea’s MFDS. Clinical studies have reported a strong safety profile.
Which products contain Seanol®?
Every product in the range — eye drops, brain supplements, skin boosters, body creams, hair renewal, daily vitality, and pet formulas — is built on the same patented marine polyphenol from Ecklonia cava.

Seanol Hydronetwork™
A three-step skin support network: Protect — phlorotannins shield skin cells from oxidative stress and calm the inflammatory cascade. Supply — supports blood-flow delivery of nutrients to skin tissue. Rebuild — supports the skin's extracellular matrix, hyaluronic acid binding, and natural moisture retention.
Hema Complex™
A dual-mechanism formula for aging pets: Seanol® supports microvascular circulation, while the complex supports normal red blood cell production. In real-world use with veterinarians, owners observed improvements in blood markers — supporting vitality in senior dogs. Individual results vary.
