Plant-Sourced Minerals, part of Natural Vitalitys plant-sourced Foodiceuticals line, are a purified-water extraction of soluble plant-derived minerals. The minerals are sourced from a prehistoric plant deposit called Senonian Vegetate, formed approximately 70 million years ago. This vegetate is mineral-rich organic soil derived from plants and naturally protected from mineral depletion. Plant-Sourced Minerals are minimally processed and include naturally occurring humic and fulvic acids, polysaccharides, lipids and other valuable nutritional cofactors. PSM delivers a complex of more than 70 plant-based, small-particle, bioavailable life-sustaining trace minerals in an easily digested and assimilated form. Both Plant-Sourced Minerals liquid and caps are measured by weight. They are a highly bioavailable, small-particle complex of over 70 different minerals and other valuable nutritional cofactors. Our caps and PSM liquid weigh differently but are comparable in mineral complex content.
