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.

Good, but keep up with labs in case you need More
I trust the company, I've done my research and have heard great things. I've been taking a supplement for a while. Unfortunately, at my last doctors visit, I was prescribed a prescription strength vitamin D because I was extremely low even after taking this product for quite a while. However, every person is different, different needs at different times, based on so many variables. Now that I am off my prescription dose. I will continue to take this supplement as I do believe in the company and their products and my doctor did not object.
