Frequently Asked Questions

What is Sea-Iodine?

Sea-Iodine is a proprietary formula made from organic marine algae designed to support healthy iodine levels without the use of salt. Many individuals choose to avoid table salt in an effort to minimize their sodium intake, but reduced iodized salt intake can lead to suboptimal iodine levels.
