Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Seaweed is becoming increasingly popular in the Western part of the world, especially sushi wrapped in nori and seaweed salad, also called wakame. There are limited data on the iodine content of different seaweed products in the Norwegian Food composition table. Furthermore, there is limited available research regarding in vivo bioavailability of iodine from seaweeds. The objective of this study is to assess whether iodine from a sushi meal (with nori, Porphyra spp), and a wakame salad (Undaria pinnatifida) has similar bioavailability as a potassium iodide reference supplement of similar iodine content.
