Freshwater bogs, where cranberries are typically sourced, are not considered high-iodine environments. Iodine is naturally more abundant in the ocean, so cranberries from bogs close to the ocean may have slightly higher iodine levels. Our supplier confirmed that these bogs are located in the US, but could not provide a specific location. The iodine content in cranberries is measured in micrograms, which is a small amount. Given the small servings of cranberry powder suggested for cats and dogs, the iodine levels are minimal and should not be a cause for concern. It is important to note that concentrated iodine levels in marine seaweeds could pose more of a concern if over-supplemented.
