Minerals Suspended in Seawater Easier to Absorb

Modern people tend to be low on certain minerals. In particular those minerals that are hard to absorb in certain forms such as magnesium. Yet, its been found that minerals suspended in ocean water can be absorbed more easily than minerals found in veggies. This applies to calcium, magnesium and a few other trace elements found in the sea. I'll try and find the studies that support this information and get it up on the site.
