Flavor variants in a product family share the base profile, and the oxalate table follows the base more than the flavoring. Hemp Hearts Seeds measures 11 mg per serving, in the middle of the family range. 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: Sunflower Seeds (9 mg), Caraway Seeds (18 mg), Sunflower Seed Spread/Butter Seeds (6 mg).
