Lugol's Iodine: Where Does Your Iodine Come From? Over the last few months, we've been getting more calls in which customers are asking us where we get the potassium iodide and iodine crystal that goes into our manufacture of our Lugol's Iodine. Because kelp has been a major dietary source of iodine for eons, there is the general perception that all iodine comes from the sea. This is not, however, the case when it comes to pharmaceutical-grade iodine ingredients and products. Iodine products are now derived from caliche and oil-based brines.
Iodine is a chemical element. The body needs iodine but cannot make it. The needed iodine must come from the diet. As a rule, there is very little iodine in food, unless it has been added during processing, which is now the case with salt. Most of the worldâs iodine is found in the ocean, where it is concentrated by sea life, especially seaweed.
