Caviart Black Seaweed Pearls from Season Brand are not only healthy for us and chock full of iodine, B-12, and other vitamins and minerals. They’re also healthy for the seas. As one of the least invasive forms of aquaculture, these little gems require no infrastructure, fertilizers, and virtually no ecological footprint. Seaweed grows rapidly, making it a highly sustainable food source that also adds oxygen to the water. You can be sure anything this good for people and our planet is an equally good fit with Season. Caviart is Certified Kosher-Parve by the Mosaiske of Denmark. The OU does not supervise Caviart production.
