Frigo Cheese Heads Whole Milk String Cheese, 10 oz, 12 Count Bag
Frigo Cheese Heads Whole Milk String Cheese uses whole milk mozzarella (rather than the more common part-skim version), giving it a richer fat content per stick while keeping net carbs to about 1g, and SureKeto's food database independently rates the Cheese Heads line as keto-friendly with a clean ingredient list (pasteurized milk, cultures, salt, enzymes) free of sugar or refined oils.

Organic Valley Stringles Mozzarella String Cheese Sticks, 8 Count (8 oz)
Organic Valley Stringles is made from just three ingredients — organic cultured pasteurized part-skim milk, salt, and vegetarian enzyme — sourced from pasture-raised, non-GMO cows with no artificial hormones or antibiotics, and comes in at 0g net carbs per stick. SureKeto independently rates Stringles as excellent for keto, citing its carb-free profile and clean ingredient list free of additives, making it a step up in sourcing transparency and certification (USDA Organic, Non-GMO) versus a conventional whole-milk string cheese.
