Abstract
Abstract A water based drink formulated for consumption by people engaged in athletic or other strenuous activity is disclosed. The drink comprises purified water to which has been added electrolytes (ions) of the type normally lost in such activity and in amounts in proportion to which the electrolytes are normally lost. The drink does not include sugar which increases osmolarity and retards gastric emptying. The drink may consist essentially combinations of purified water, sodium chloride, sodium phosphate, potassium chloride, potassium phosphate, calcium chloride and magnesium chloride with the salts being proportioned as stated.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
133 words
A fluid replacement drink for rapidly restoring bodily fluids and rapidly replacing physiologically important electrolytes in the proportions which they are lost during strenuous physical activity, consisting essentially of: a. from about 0.006 to about 0.010 wt.% sodium chloride or from about 0.00900 to about 0.00150 wt.% sodium phosphate; b. from about 0.0045 to about 0.0075 wt.% potassium chloride or from about 0.065 to about 0.0109 wt.% potassium phosphate; c. from about 0.00375 to about 0.00613 wt.% calcium chloride; and d. from about 0.000912 to about 0.000312 wt.% magnesium chloride; and e. purified water; said electrolytes combined in an effective amount such that the osmolarity of said drink is not more than approximately 50-80 m. osm. per liter to ensure that the stomach is emptied of fluid and electrolytes at a controlled rate.
