A genus of brown seaweed (kelp family) used as a food and dietary ingredient, related to the more commonly eaten wakame.

Why it’s used

Taken as a natural source of iodine, minerals, and fiber, sometimes marketed loosely for thyroid or general nutritional support.

What the evidence says

Seaweeds as a category are well documented as concentrated dietary sources of iodine, but direct clinical research on Alaria as a supplement ingredient specifically is minimal, so effects beyond its known mineral content are not established.
