Query: Actual Magnesium dose

The most disappointing thing is the failure to show the actual elemental magnesium in the pills. I think it is deceptive to put 500 mg Magnesium Gluconate up front on the label, make it difficult to see the ingredients list and then into the bargain leave the consumer to figure out that two tablets have ?64 mg elemental magnesium/14% daily value - 32 mg Magnesium Gluconate per tablet.
