Some corrections in the extra: "lack of citrate leads to hypocitraturia → leads to less citrate in the urine = increased chance for calcium stones
I forgot to take out the vitamin C part of the sentence, the most important and misleading part (doh!!)
So is there going to be another edit to remove the bit about vitamin c?
The vitamin c abuse is fine and is correct. The orginial reason confusing citric acid with vitamin c is false and needed editing. Additionally, since citrate deficiency is also a viable answer as well, it was included in the correction.
