Iodide.
The Chloride form raws purity is about 60%-70% (when it's found, more rare), and also more pricey.
The Iodide is +98%, so it allows accurate dosing of the tablets.
That said, few people care really about the difference and from a sales point of view, providing double price for a product, because of a small detail that 90% if its buyers ignore and don't care about, is not the best choice for sales.
I think you get my point, but I know that the chloride is known to be better, but what is the remaining 40-30% impurities, are they harmful compared the harm of iodide, no idea.
Requires more advanced research and testing to estimate pros and cons of each.
