Urinary Health Diets Benefits

Provides nutrition that aids in the management of pure struvite uroliths.

Urine Dilution

Increases urine volume to reduce the saturation of urine containing calcium and struvite crystals.

S/0 Index

This diet promotes a urinary environment unfavorable to the development of both struvite and calcium oxalate crystals.

Controlled Magnesium

RSS: What It Is And What It Does

the concentration of ions contributing to struvite and calcium oxalate urolithiasis.
