Symbrosia: Solving climate change with the world’s mightiest seaweed.

Solving climate change with the world’s mightiest seaweed

Made from the red seaweed Asparagopsis taxiformis, Symbrosia’s SeaGraze helps to reduce methane expelled from livestock, a major contributor to climate change. The Hawaii-based company conducted the world’s first commercial trial of Asparagopsis in 2020 and saw a reduction of over 75% in methane produced by livestock. SeaGraze intercepts the formation of methane without impacting the fatty acids that are involved in the production of meat and milk.
