Research & More Information

PC Ecklonia Cava


BioPure’s PC-Ecklonia Cava is extracted from the brown algae Ecklonia Cava (Luminariaceae japonica) which is grown in deep, cold, pure ocean waters off the coast of Korea, China and Japan.  BioPure’s PC-Ecklonia Cava Extract is a potent source of polyphenolic compounds.  Naturally rich in iodine, manitol, fucoidan, alginates, fucoxanthin, lamarin, eckol and dieckol PC-Ecklonia Cava also contains all of the 72 different trace minerals.*


Studies have shown PC-Ecklonia Cava Extract to be a very robust antioxidant.  Antioxidant strength is measured by the amount of rings composing its structure. Flavonoids usually contain three interconnected rings.  Green tea catechins contain 4 interconnecting rings whereas PC-Ecklonia Cava has up to 8 interconnected rings making it 10-100 times more powerful to fight off free-radicals than other polyphenols.*


BioPure’s PC-Ecklonia Cava Extract is a 98.8% pure extract of this algae, providing a potent source of polyphenolic compounds and all of the 72 different trace minerals.*  BioPure’s PC-Ecklonia Cava Extract has a remarkably high antioxidant (ORAC) value of 8300, and a half-life of 12-14 hours.*   


Studies have consistently shown that the active ingredients in Ecklonia Cava possess a wide range of properties beneficial to maintaining optimal health.*

PC-Ecklonia Cava

Ecklonia cava is an edible seaweed that grows in oceans off the coasts of Japan and Korea. This brown algae contains high concentrations of phlorotannins, a particular type of polyphenolic compound not found in terrestrial plants, and known to be a highly effective antioxidant1,2. The power of an antioxidant is determined by the number of rings in its structure. Ecklonia cavaextract (sometimes referred to as ECE) has up to eight rings, meaning its antioxidant power is 10-100 times stronger than other polyphenols2. ECE is uniquely effective, partly due to the fact that it is insoluble in water. Its hydrophobic chemistry allows Ecklonia’s polyphenols to remain metabolically active up to 12 hours, whereas most water-soluble, land-based polyphenols have only a 30-minute half-life2. This property also allows the phlorotannins to pass through the blood-brain barrier, and may contribute to improving mental acuity and memory. Some research has shown that the phlorotannins of ECE are implicated with beneficial anti-diabetic3, anti-HIV4, anti-hypertensive5, anti-fibromyalgia2, and anti-allergic activities6. ECE also shows promise to help the body fight against lung7and colon cancer8. Ecklonia cava extract can also support the body in defending itself against arthritis, osteoarthritis9, metastasis10, chronic inflammation10, and even wrinkle formation10.

Ecklonia cava extract has been given the brand name of “Seanol” for sales and distribution in the United States. BioPure Healing Products, LLC is proud to offer 400mg capsules of Seanol-F that are free of preservatives and magnesium stearate, a filler that many people are allergic to. (Additional ingredients: L-Leucine and vegetable cellulose.)
