Rugby® Sodium/Potassium/Phosphorus Supplement Packets provide bioavailable mineral replacement therapy equivalent to Phos-NaK® formulations at reduced cost. This electrolyte and phosphate combination addresses deficiencies arising from renal dysfunction, malabsorption syndromes, or pharmaceutical interactions requiring mineral supplementation. The sugar-free, fruit-flavored powder dissolves rapidly in aqueous solutions, facilitating convenient dosing for patients with swallowing difficulties or those requiring precise mineral quantification. Each 1.5g packet delivers standardized electrolyte ratios essential for maintaining acid-base balance, neuromuscular function, and cellular energy metabolism. Ideal for individuals with diabetes, renal compromise, or documented mineral insufficiencies requiring pharmaceutical-grade supplementation.
