Potassium

Potassium is called the "alkalizer." It neutralizes acids and restores alkaline salts to the blood stream. Potassium works with sodium in all cells including at nerve synapses to maintain or restore membrane potentials and assist in metabolic processes.  Potassium is critical to cardiovascular and nerve function, regulating the transfer of nutrients into cells, and facilitating muscle energy. Potassium also regulates water balance, assists recuperative powers, aids rheumatic or arthritic conditions (causing acids to leave the joints and ease stiffness), is vital for the elimination of wastes, is a natural pain desensitizer, helps control convulsions, headaches and migraines, promotes faster healing of cuts, bruises  and other injuries and generally contributes to a sense of well being. Potassium is stored in the muscles.
