In a double blind placebo study against Viagra, Fibronol (Ecklonia Cava) came out on top for almost all markers. See this free PDF Report Report for details, care of Dr. Haengwoo Lee.
What is in it?
Fibronol® contains Seanol-F, a patent-pending brown seaweed extract. Seaweeds, or algal plants, have long been used by traditional cultures worldwide for food and medicine. Seaweeds are organized into four classes:
green algae (Chlorophyceae)
blue-green algae (Cyanophyceae)
red algae (Rodophyceae)
and brown algae (Phaeophyceae).
Some green algaes, such as sea spaghetti, are used as food. Blue-green algae are found in both seawaters, and in fresh waters, such as the well-known edible Klamath Lake blue-green algae, Aphanizomenon flos-aquae. Red seaweeds include agar-agar, dulse, Irish moss and nori.
Brown seaweeds include arame, hijiki, kombu and wakame, and are known for their use in Asian cuisines. Both red and brown algae are rich in polysaccharides, which are utilized for their gelling, emulsifying and stabilizing properties. Agar and carrageenan are polysaccharides extracted from red seaweeds; algin is extracted from the brown seaweed giant kelp.
Ecklonia cava, called noro-kajime in Japan, is the edible brown seaweed that serves as the source for Seanol-F. E. cava is used commercially as a source of hydrocolloids, such as alginate, and as a soup ingredient in Asia. It is also considered a source of iodine.
Seanol-F is a standardized complex of unique natural molecules from E. cava. Seanol-F contains phlorotannins, polyphenolic compounds not found in terrestrial plants but only in certain brown algal species. Phlorotannin-rich extracts of E. cava show significant antioxidant activities, including DPPH radical scavenging, ferric ion reduction, peroxynitrite scavenging, and inhibition of LDL oxidation. As well as modulating levels of reactive oxygen species (ROS), phlorotannins may modulate levels of PGE2, cytokines and prostaglandins.
