Once home, I first thought of poke bowls, but I quickly realized this seaweed salad is versatile. That led me to look deeper into its ingredients, nutrition, storage, and best uses.

Seaweed Salad Costco Nutrition – Is Costco Seaweed Salad Healthy?
Seaweed is nutrient-dense. A 1/2 cup serving of this salad has roughly 110 calories, about 6 grams of fiber, some iron (around 6% DV), and potassium (about 10% DV). It also contains about 600 mg of sodium and roughly 6 grams of added sugar per serving. Its high fiber and low-calorie profile make it a satisfying side that can help you feel full longer, but watch portions for sodium and added sugar.
Does Costco Seaweed Salad Have Iodine?
Yes. Seaweed is naturally rich in iodine, an essential mineral for thyroid function and metabolic regulation. Because seaweed is the main ingredient, this salad will contain iodine, though exact amounts depend on the seaweed variety and source.
Can You Eat Seaweed Salad Every Day?
Moderation is recommended. Seaweed can be high in iodine, and excessive intake of iodine may be harmful for some people. Many experts advise limiting seaweed consumption to a few times per week rather than daily. If you have thyroid conditions or take certain medications, consult a healthcare professional about how often to eat seaweed.
Azuma Seaweed Salad Cancer Warning
You may notice a California Proposition 65 warning about “cancer and reproductive harm” on the container. This is a mandated consumer notice for products that may contain certain chemicals, such as trace amounts of heavy metals commonly found in some seaweeds. The label does not mean the product is unsafe for most consumers, but it does indicate that California requires disclosure of potential exposures. Studies of farmed edible seaweeds have generally found them safe for consumption, though research and regulations evolve over time.
How to Store Costco Seaweed Salad
Keep the seaweed salad refrigerated. When chilled, unopened tubs have a shelf life printed on the container; refrigerated product can last up to about 30 days unopened. After opening, consume within 5–7 days for best quality. For longer storage, the manufacturer notes the salad can be frozen in its original container for up to two years; once thawed, keep it in the refrigerator and use promptly. Thaw in the refrigerator rather than at room temperature to protect both food quality and the plastic container.
