That is what the Rx foods contain to prevent crystal formation. Oxalate crystals (acidic pH) are harder to get rid of. Also, chicken or turkey gizzards are very high in methionine so it's good to add these to the diet on a regular basis if crystals are struvite.
Here's some info on l-methionine:

Fortunately he has struvite crystals - which I understand are much easier to control with diet.
