TRC Minerals are known throughout the world as the strongest concentrationof the most complete full spectrum of pure Plant DerivedMinerals ever presented to the nutritional industry. These minerals areleached from Senonian Vegetate? that is mined from the United MineralsMine in Emery County, Utah by TRC Minerals, Inc.According to scientists, the Senonian Vegetate apparently accumulated inthis central Utah area during the senonian period when plants could stillpull 75-80 minerals from futile soils as they grew. Plant minerals arecompletely different than metallic minerals that come unaltered from thesurface of the earth. Plant minerals are water soluble, hydrophilic innature, whereby metallic minerals are non-water soluble, hydrophobicminerals. Most nutritional experts and many doctors agree that plantminerals are possibly 100% assimilated by the body compared to no morethan 8% assimilation of metallic minerals. This difference in assimilation(absorption) could make a significant difference in overall health
