FibroBoost® contains Seanol®, a unique polyphenol complex from brown algae (Ecklonia cava). Seanol is produced using a patented extraction process that creates a complex of ten sea-based polyphenols. Widely studied for their health benefits, polyphenols are a diverse class of naturally occurring compounds found abundantly in the vegetable kingdom. Polyphenols from land growing plants are largely water soluble, breaking down rapidly in the body when consumed in food. In contrast, Seanol polyphenols are hydrophobic (repelled by water and therefore non-water-soluble); this allows them to remain in the body for up to twelve hours before being metabolized and excreted, greatly enhancing their beneficial health effects.

The polyphenols in Seanol are designated as "phlorotannins" based on their complex chemical structures. Polyphenols are built on a skeleton structure composed of two or more "phenolic rings." The lauded antioxidant properties of polyphenols stem from the ability of these rings to absorb unpaired electrons from free radicals. Phlorotannins contain numerous phenolic rings, making them powerful free radical scavengers, as confirmed by ORAC analysis. (ORAC is a laboratory analytical technique that measures the in-vitro capacity of a substance to neutralize free radicals.) Patented methods are used to extract and purify polyphenol/phlorotannins from Ecklonia cava.
