Traditional Uses: Traditionally used in coastal European and Asian cultures as a natural source of iodine to prevent goiter and support thyroid health, and as a soil conditioner in agriculture.

Potential Benefits: May serve as a source of dietary iodine to address deficiencies; fermented Laminaria japonica (1.5 g/day for 6 weeks) showed improvements in cognitive function (memory, visual reasoning) and physical fitness (walk tests, mobility) in a 2018 study of healthy seniors. However, there is insufficient data to support kelp for weight loss, blood pressure, or other health claims.

Warnings: Avoid during pregnancy and breastfeeding (unsafe, can affect infant thyroid); contains highly variable and potentially excessive iodine levels that can cause or worsen both hyper- and hypothyroidism, especially in those with thyroid disorders or taking amiodarone, antithyroid drugs, or thyroid hormone; may contain toxic heavy metals (arsenic, lead, cadmium).
