This certified organic Kelp thallus is grown in clean ocean waters of the Atlantic Ocean, off the coast of Canada. The 'organic' status assures that each harvester must monitor their beds for sustainability. They must keep their freshly picked plants clear of possible contaminants throughout the harvest transport, drying and packing process. The plants are tested for contaminants, heavy metals and, now, radiation.

Background and Use

Seaweed has been used medicinally in Asia for over 5,000 years. The sea vegetables (of which there are numerous species) have been used in traditional medicine, cosmetics and consumed as a food.

In the 1860's, it was discovered that some seaweeds, such as Kelp, serve as thyroid stimulants, due to the high iodine levels found in these plants. The thyroid gland needs dietary iodine to produce the thyroid hormones which regulate metabolism in every cell of the body and play a role in virtually all physiological functions. In the United States, it is rare to have an underactive thyroid brought about by an iodine deficiency, due to the fortification of salt with iodine (iodized salt). However, recent trends show that people are getting less iodine dietarily, due to a reduction of salt in their diet.

Consult your health care professional if using Kelp for thyroid imbalance.  Do not take if pregnant or nursing. Keep out of reach of children.  Discontinue if unusual symptoms occur. Do not exceed recommended dose unless under the guidance of a health care professional.


A small percentage of people are sensitive to iodine and could develop a painful and enlarged thyroid gland if they consume iodine rich substances such as Kelp for longer than one month.
