Hello. Thanks for the question.
When we have calcium oxalate crystals, I don't usually worry too much unless they are forming stones. If we have calcium oxalate stones, that is something I want to prevent. I usually recommend Hill's U/D diet. If that is not preventing them from forming, then I'll add potassium citrate.
The high ALP is a little concerning. I would want to rule out Cushing's as that is a common cause of an elevated ALP. This is where the adrenals are overactive producing cortisol.
If he were my case, I would feed Hill's U/D. If I were still seeing crystals in 1-2 months, then I may add Potassium Citrate.
I hope this helps, let me know if you have any other questions.
