Now Foods Potassium Gluconate Pure Powder, 1-pound
Potassium is an important mineral used in various bodily functions.  It is an important factor in the maintenance of the body's acid-base balance and nerve conduction, as well as the transfer of nutrients through cell membrances.*  Potassium is found in a number of foods, including dairy, fish and other meats, fruits, vegetables and whole grains.  Because food processing reduces the levels of naturally occurring nutrients in foods, supplementation may be necessary to insure adequate intake.   NOW has been selling powdered supplements since 1968 because of their distinct advantages.  The powdered form is 100% pure and free of fillers and preservatives.  It is also more economical and can be taken in desired potencies.
