Butter (Salted) measures 0 mg per serving, in line with the rest 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: Butter (0 mg), Butter (Unsalted) (0 mg).
