Here's a link to a pretty comprehensive study done recently which does include Oceanic Sea Salt as well as 8 other brands. It is a comparisson of which trace elements are in each salt mix as compared to natural seawater. They do not delare one better than another but just publish the results. It seems to me that based on their findings, Crystal Seas Marine Mix Bioassay is the closest overall to natural seawater. What do you think? Anyway, here's the link:
