Over the last few years, seaweed has become increasingly common on our plates. Fresh, dried or as a food supplement, its iodine content varies and can sometimes be high. ANSES assessed the risk of excess iodine intake from the consumption of seaweed-based products. In view of the non-negligible risk of exceeding the upper limit of safe intake for iodine, the Agency advises against the consumption of seaweed and seaweed-based food supplements by certain at-risk populations, and recommends that regular consumers remain vigilant.
