Seaweed, kelp and iodine-rich products

Food portions of seaweed differ greatly in iodine; concentrated kelp, sea-moss and iodine products need an exact-product review.

Direct guidance

What to know or do

Occasional nori is not the same as a daily kelp supplement or concentrated drink. Check the species, serving and iodine amount, especially with thyroid disease or a prenatal vitamin containing iodine.

What changes the answer

  • Whether every ingredient is pasteurised or cooked through
  • How the food was chilled, stored, handled and reheated
  • The exact species, product label, recall or contamination warning

When to get individual help

Check the exact item or situation with a doctor, midwife, pharmacist or relevant clinician; the name of a broad category is not enough for a personal decision.
