Bottom line up front:

Seaweed is a good source for iodine but should not be a staple food as too much iodine can be harmful.

 

What is it?

It is a vegetable that grows in the sea.  It generally has very low calories, no protein, and only a little bit of carbohydrates.  It does on the other hand have a lot of minerals in it.  Specifically iodine.

 

What does that mean?

Seaweed is a fantastic source for iodine.  Iodine supports thyroid health.

 

Why might you take it?

To improve thyroid health.

Help with bowel function since it can be high in fiber.

Weight loss due to the high fiber content.

 

How much can I take?

Can be used to make food.

No specific recommended amount.

 

What happens if I don’t get enough?

Nothing.

 

What happens if I take in too much?

Because it is high in iodine you run the risk of getting high iodine levels.

High iodine levels can actually cause troubles for the thyroid.

This should be used in certain dishes but not taken at high amounts.

 

What can I eat?

Seaweed

Seaweed flakes

 

Final take:

I would try seaweed in my diet as a way to mix in some iodine and to try new flavors.

Using it specifically to support your thyroid is likely not needed since we add iodine to many foods already.
