Unique Marine Polyphenol Complex That Supports Health And Well-Being. Science Based Nutrition. FibroBoost contains Seanol a unique polyphenol complex from brown algae (Ecklonia cava). Polyphenol compounds are abundant in plants and their intake is associated with many important health-promoting qualities. Seanol is a potent marine-based source of polyphenolic compounds with strong antioxidant properties. Unlike most land-based polyphenols that are hydrophilic (water-soluble) Seanol contains hydrophobic compounds that are able to cross the blood-brain barrier allowing for antioxidant support of the brain and neural tissues.  . FibroBoost has been studied for safety and efficacy for nearly two decades and has been found to support the heart memory function joints muscle function immune function a healthy inflammatory response and healthy metabolism.  .
