This is one brand that prides itself on using completely ordinary ingredients. The seaweed used in the SeaSnax line is called porphyra, a red algae also known as nori. It’s sustainably harvested, roasted, and packaged in Korea, and is never combined with preservatives, artificial flavors, or colors. On the nutrition front, look at a package of the Roasted Seaweed Classic option, and you’ll enjoy some vitamin A, vitamin C, calcium, and iron. Bonus: the entire bag clocks in at only 15 calories!
