Stone Defense
Crystal Star
Overview
The effectiveness of Stone Defense is difficult to fully assess due to its proprietary herbal blend, which means the exact amounts of most individual ingredients are not disclosed. While several ingredients, such as Stone Root and Hydrangea, have some research supporting their traditional uses for kidney and urinary health, the efficacy hinges on adequate dosing. The presence of some ingredients without strong human clinical evidence for their stated benefits, particularly within an undisclosed blend, further limits a robust evaluation.
The Good
Includes Stone Root, which has some evidence for reducing kidney stone size.
Contains Marshmallow Root and Chamomile, traditionally used for their soothing properties.
Incorporates Dandelion and Parsley, commonly used for diuretic effects.
The Bad
Contains Gravel Root, which is likely unsafe due to hepatotoxic pyrrolizidine alkaloids (PAs).
Proprietary blend obscures individual ingredient dosages, preventing assessment of efficacy and safety.
High daily capsule intake (up to 6 per day) for an extended period.
Is it for you?
Best For: Individuals seeking natural support for kidney and urinary tract health, those prone to kidney stone formation
Skip If: You are pregnant, nursing, have a medical condition, or are taking prescription medications without consulting a doctor.
