SeaGraze®
For Beef That’s Better by Nature.
You're already doing the hard work. SeaGraze® helps you do it cleaner — and more profitably. A feed additive built for real ranches, backed by real science.
Why Ranchers Choose SeaGraze®
One feed additive. Multiple bottom-line benefits.
Associated with up to 80–90% reduction in enteric methane emissions in peer-reviewed studies
Cattle in a 15-month pasture trial showed a 26% increase in Average Daily Gain compared to controls
Supports rumen fermentation efficiency by redirecting hydrogen toward propionate production
In a pilot study, sheep supplemented with SeaGraze® showed markedly lower fecal parasite counts over the course of the trial
Naturally mineral-dense with organically chelated Cu, Zn, Mn, and Fe — designed to support trace mineral status in grazing herds
In heat stress research, seaweed-supplemented animals showed favorable trends in weight gain and immune biomarkers
USDA Organic. No antibiotics, hormones, or synthetic additives
No detectable bromoform residues in edible tissues across multiple controlled studies — carcass and eating quality unaffected
SeaGraze® are eligible to generate carbon credits through Verra's VM0041 methodology
In national consumer research, seaweed additives were the most preferred methane mitigation strategy for beef — with willingness to pay comparable to organic premiums

Beyond Methane:
SeaGraze® contains naturally occurring amino acids that have been shown to support gut function and nutrient absorption of cattle.
These properties may complement feed conversion efficiency and digestive health, especially in high-performance systems.

Additional Benefits for Cattle Under Research
Preliminary research suggests that SeaGraze® may help ruminants cope with elevated temperatures and thermal stress conditions.
Compounds naturally present in SeaGraze®—including zeaxanthin, beta-carotene, iodine, and sulfated polysaccharides—are known to support antioxidant defenses and metabolic stability.
These nutrients may help animals maintain performance and feed intake under thermal stress, especially in heat-prone environments.

Note: These benefits are currently under scientific investigation and are not yet validated for commercial claims.
“The supplement is proving beneficial for animal health, and farmers are excited and happy to use it. They know it helps their farm and their flock of sheep or cows, while at the same time helping the planet.”
Diana Zlotnikov, owner at Z Farms
“From a day to day perspective, it’s not any different than putting out loose mineral or putting out protein tubs, which most ranchers are doing anyways. So, when you’re looking at ways that we can have a positive impact on our environment without changing dramatically what we’re doing — SeaGraze® seems to be a great solution.”
Jacob Tavares, Manager, Livestock Business Operations at Parker Ranch
“Farmers have been feeding kelp and seaweed to their animals for millennia, for the nutritional properties. If we feed supplement that not only has the nutritional value that seaweeds have, but also reduces methane, that’s huge.”
Faith Van de Putte, co-owner of Midnight’s Farm
“We at Neutral Foods greatly appreciate the partnership that we have built with Symbrosia. As a carbon neutral food company, we’re always looking for innovative and dynamic partners who are as passionate about de-carbonizing the food system as we are. We’ve worked with Symbrosia to develop and implement a novel on-farm trial with their supplement, SeaGraze, with another equally fantastic ranching partner, Carman Ranch. The Symbrosia team has been an agile, reliable, and enthusiastic partner.”
Ann Radil, Head of Carbon Reduction at Neutral Foods
