Find healthier alternativesPlain dairy milk is one of the simplest foods in the grocery store, so small label differences are easy to compare. This ranking covers six plain cow's milks sold at Walmart, Costco, Target, and Whole Foods, ordered from highest to lowest editorial score. The scores are our estimates based on what each label shows. They are not official app or database scores.
Each score weighs processing level, additives, added sugar, sodium, and protein. Plain milk has no added sugar, so the gaps come from other factors: extra processing steps such as ultra-filtration, added ingredients like vitamin A palmitate, and organic or grass-fed claims. A high score does not make a milk right for every diet. The score also cannot account for allergies, lactose tolerance, or your preference for whole or reduced fat.
When you compare cartons, read the ingredient list first. The shortest list is usually just milk plus vitamin D. Then check the Nutrition Facts panel for Added Sugars, which should read 0g on plain milk. The FDA's Nutrition Facts guide explains each line. For what organic seals legally mean, see our organic vs non GMO guide.
The top-rated milk ranking
Grassmilk Organic Whole Milk
Grassmilk lists only organic grass-fed whole milk, with no added sugar and no added vitamins. The short ingredient list and standard pasteurization earn top marks in this comparison.
100% Grass-Fed Organic Whole Milk
Maple Hill uses one ingredient, organic grass-fed whole milk, and has 0g added sugar. Some versions are ultra-pasteurized for a longer shelf life, which costs a point on processing.
Organic Whole Milk
Horizon's organic whole milk has no added sugar and adds only vitamin D3. It scores slightly lower because it is ultra-pasteurized and is not labeled grass-fed.
Organic Reduced Fat Milk
This Costco organic 2% milk has 0g added sugar and 8g protein per cup. The added vitamin A palmitate and vitamin D3 lengthen the ingredient list slightly.
Reduced Fat Ultra-Filtered Milk 2%
fairlife provides 13g protein and about half the sugar of regular milk per cup through ultra-filtration. The extra processing step and added lactase enzyme and vitamins lower its score.
2% Reduced Fat Milk
Walmart's 2% milk contains milk, vitamin A palmitate, and vitamin D3, with 0g added sugar. It is conventional and not organic, which places it last in this comparison.
