Moonstone Stone Stopper Drink Mix, Cranberry Raspberry, Kidney Stone Prevention, Calcium Oxalate Protector, Developed by Urologists to Improve Hydration and Support Kidney Health, 15 Day Supply

One assumed packet supplies meaningful magnesium but only 200 mg potassium and no declared citrate, making the disclosed formula clearly partial for its kidney-stone-prevention purpose.

The applicable chemical forms of magnesium, potassium, and vitamin B6 are not identified, so their absorption and tolerability properties remain unresolved.

Directions are not supplied, so one 13.1-gram packet daily is assumed as the labelled serving and confidence is low.

The listed nutrient amounts are internally consistent, but the absent chemical forms and directions leave important product details unresolved.

The formula combines relevant minerals, but it does not declare citrate or another clearly identified urinary alkalinizing component needed to fully support the stated prevention role.

The label lists no problematic additives, but it provides no product-specific testing or other evidence supporting a higher purity assessment.

Vitamin B6 is declared at a meaningful amount and may be complementary to the mineral formula, but added clinical benefit for this purpose remains uncertain.
