SwansonKelp Iodine Source

Kelp is a type of large seaweed that grows in cold, mineral-rich ocean waters. This supplement uses Ascophyllum nodosum, an Atlantic kelp species found along the coasts of Northern Europe and North America. This species is often chosen due to its controlled composition and stable iodine content.

There are several types of kelp, such as Ascophyllum nodosum, Laminaria digitata and Macrocystis pyrifera. They vary in growing location, nutrients, and iodine content. Ascophyllum nodosum is often used in supplements because of its mild flavor and consistent iodine profile.

The kelp used is standardized, which means that 0.4% of the kelp extract is iodine. This way, you know exactly how much iodine you are getting per tablet.

Iodine from kelp is a natural source, derived from seaweed. Other supplements may contain synthetic iodine, such as potassium iodide.

Pay attention to the total daily intake of iodine, including from food. Do not use with thyroid problems. Always follow the recommended dosage on the label and contact an expert if you have questions.
