Science, nature and purpose
Who are we ?
We are a team of conscious entrepreneurs, scientists and health and beauty lovers, all with a shared determination to make a positive impact on the world we live in. We believe in a business model that applies regenerative and circular practices to sustainably unlock the intelligence and power of nature. Sea Theory standards require that all seaweed is sustainably grown, harvested, processed and the end products developed and distributed in a way that is honest, ethical and fair.
Harnessing the power of the ocean
Why Seaweed?
Seaweed is one of the most sustainable of all nature’s crops. Algae do not compete or displace land use for food or supplement production, so the two particular seaweeds that we use to provide our active ingredients have a huge potential to contribute to the security of our raw ingredients supply.
It’s also important to note that the ocean is the world’s largest carbon sink, powered predominantly by algae which filters nutrients from the water and reduces acidification, contributing significantly to the mitigation of climate change.
Our commitment runs deep
Sea to Self
We are committed to circularity and to becoming a carbon positive company. This plays a key role in all decisions we make, from Sea to Self. Every element is considered, from our choice of suppliers, the processes we use, the packaging we choose for our various products, and the commitment we make to cultivating our own seaweed at our hatchery on the Atlantic Coast.
