Why it helps at midlife
Iodine is essential for making thyroid hormones, and thyroid issues become more common in women in midlife — so seaweed's iodine can be helpful in moderation. But this cuts both ways: some seaweeds (especially kelp/kombu) are extremely high in iodine, and too much iodine can itself disrupt thyroid function. Enjoy nori and moderate amounts of sea vegetables as part of a varied diet, and be cautious with concentrated kelp, particularly if you have a thyroid condition — check with your clinician.
Food supports overall health — it doesn't treat or cure any condition. Talk to your clinician about symptoms, supplements, or a diagnosis.
How to use it
- Use nori sheets for wraps, poke bowls and homemade sushi.
- Add a little wakame to miso soup and salads.
- Crumble toasted nori over rice and grain bowls as a savory topping.
Good to know
- Go easy on kelp/kombu and kelp supplements — they can deliver excessive iodine.
- If you have thyroid disease, ask your clinician before eating seaweed regularly.

Frequently asked questions
It supplies iodine, which the thyroid needs, so moderate amounts can help. However, excess iodine — easy to get from high-iodine kelp — can disrupt the thyroid, so more is not better.
