Kelp is a large, brown seaweed that forms underwater forests in shallow, nutrient-rich coastal waters around the world, offering a savory umami flavor and a distinctive texture when consumed raw or cooked.
Kelp is one of the most concentrated food sources of iodine, an essential mineral for thyroid function, but its levels are highly variable and can easily exceed the safe upper limit of 600 µg per day .46
Regular or excessive consumption of kelp is linked to thyroid dysfunction, including both iodine-induced hypothyroidism (underactive thyroid) and hyperthyroidism (overactive thyroid), particularly in iodine-sufficient populations .34
Because of the extreme variability and potential for excessive iodine content, kelp-based supplements are generally not recommended for pregnant women .34
Kelp contains unique functional compounds such as alginate (a thickening dietary fibre) and fucoxanthin (a carotenoid pigment), which are currently being studied for their potential roles in metabolism and weight management .89

Kelp farming is environmentally friendly, requires no freshwater, pesticides, or fertilizers, and helps sequester carbon and mitigate ocean acidification.
The word "kelp" was historically associated with seaweeds burned to produce soda ash, and its etymology is believed to stem from old Gaelic words meaning 'young female cow' or 'young male horse'.
