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

Urine Dilution
Increasing the urine volume simultaneously reduces the saturation of urine with calcium oxalate and struvite crystals.

Low RSS
Relative Super Saturation (RSS) methodology predicts the crystallization potential of urine; RSS is used to develop diets that lower the concentration of ions contributing to struvite and calcium oxalate urolithiasis.

Controlled Magnesium
Reduced level of magnesium, a natural component of struvite stones.
