Frequently Asked Questions
What is Ecklonia cava?
Ecklonia cava is a brown seaweed native to the coastal waters of Japan, Korea, and China. It is distinguished by its phlorotannins — unique marine polyphenols found only in brown algae — which have demonstrated potent antioxidant, anti-inflammatory, and neuroprotective properties in research studies.
What is the recommended dosage for Ecklonia cava extract?
Most studies use 100-400 mg per day of standardized extract. Branded extracts like Seapolynol have been studied at 72-144 mg/day. Due to its iodine content, individuals with thyroid conditions should consult a healthcare provider before use, and those on blood thinners should exercise caution.
How does Ecklonia cava compare to other seaweed supplements?
Ecklonia cava is unique among seaweeds due to its high concentration of phlorotannins, which have a longer biological half-life than most land-based polyphenols. While other seaweeds like kelp provide iodine and fucoidan, Ecklonia cava has the most clinical research specifically supporting cognitive and cardiovascular benefits among edible brown algae.
