U.S. Rare Earth Minerals, Inc. has been blessed with the rights to mine what is widely considered the rarest source of ancient lake bed sediments found to date. A host of scientists recognize it as the richest known source in the world for natural occurring macro, micro and nano nutrients. These minerals and trace elements have been naturally chelated in the presence of Humic and Fulvic acids to produce the powerful combination that we call Excelerite.
