lora Premium Vegetal Silica is prepared by utilizing a unique aqueous extraction method developed and patented by Dr. Louis Kervan. This method of deriving a silicon extract from spring horsetail using only water, without any chemicals or solvents, ensures the vegetal silica is bonded, or "chelated," to a group of water-soluble bioflavonoids. Only silica chelated with bioflavonoids offers a safe and highly bioavailable form of silica that is easily assimilated by the body. *These statements have not been evaluated by the Food and Drug Administration.
