Made from the red seaweed Asparagopsis taxiformis, SeaGraze® is good for cows, great for farmers, and even better for the planet.

SeaGraze® is unique.

Enhanced palatability.

Our single-phenotype seadstock eliminates the need for any flavor-enhancing additives. No molasses needed.

High in metabolites, lower inclusion rate.

We’ve demonstrated double the methane reduction with the same amount of product inclusion as our competitors. Expect lower costs from us over time.

Keep carbon revenues and data.

Our business model doesn’t rely on carbon credits, those revenues stay with the land stewards. Data ownership remains with the operation.

How we grow SeaGraze®

We grow our red seaweed using sun and seawater in Hawaiʻi. 

We use a farming process called aquaculture where we utilize deep sea water, tapping into its nutrient-rich properties to enhance seaweed growth. We use zero fresh water in our growing process.

Next, we process the seaweed into SeaGraze® using 100% renewable energy.

Our processing method ensures the 90+ micro and macronutrients in the seaweed remain bioavailable.

Founding Research

  • The United Nations has declared 2020-2030 the “decade of ecosystem restoration.” While seaweed has long been touted for its impressive array of restorative ecosystem services, only recently has research started to uncover algae’s potential within the food, animal feed, and biofuel sectors. 

    In 2014, Dr. Kinley at James Cook University and CSIRO profiled a number of native Australian seaweeds for their potential to reduce methane emissions when utilized as a feed additive for livestock. Asparagopsis taxiformis outperformed all others with 1-2% feed inclusion resulted in 99% reduction of methane in an in vitro model.  

    Continued research at UC Davis, Penn State, and CSIRO has shown that the methane reductions hold up in vivo and using the supplement does not have any adverse effects on animal health, milk, or meat. 

    Trials are showing that 0.5% inclusion in cattle’s daily diet could result in a sustained 80% methane reduction — a true sweet spot for the industry. 

  • Harvesting this seaweed from the wild will result in massive ecological damage; there is simply not enough biomass available. Removing significant amounts of wild seaweed would also decrease the ecosystem services they provide, such as bioremediation and habitat creation, thus further reducing the natural resilience of ocean ecosystems. To avoid these damages, we need to farm it using a technique knowns as aquaculture. 

  • Symbrosia is uniquely positioned to determine ideal growing conditions, select strains with target metabolites and high growth rates, allowing us to not just farm it, but farm it efficiently and sustainably.
