Flavor variants in a product family share the base profile, and the oxalate table follows the base more than the flavoring. Guava measures 83 mg per serving, at the high end of the family. The useful reading is the family spread: if the range is narrow, flavor choice is free; if it is wide, the flavor with the lower measured value is the easy win. Related forms in this family: Guava (Raw) (1 mg).
