Urology/Calcium Oxalate Kidney Stones


Is Magnesium Citrate the best supplement I can take to prevent further formation of calcium oxalate kidney stones?


Not necessarily.  In general, we recommend increased water, less dietary salt and low meat protein.  However, to really know what you problem is, you need to have a 24 hour urine test done specifically for stone preventino.  That way, we know the exact type of chemical problem involved.

Until then, focus on urinary volume not just on the amount of fluids drunk.  Optimal is about 2000 ml per day (average is around 1400).
