High Protein Milk: How Much More Protein You Get

High protein milk is cow’s milk processed to carry more protein per cup. A cup of fairlife 2% ultra-filtered milk has 13 g, and a 250 mL serving of Dairyland protein milk in Canada has 18 g. A cup of ordinary 2% milk has 8.1 g. The fairlife cup also has half the sugar and about the same calories.

What is high protein milk?

Mostly it’s ultrafiltered milk rather than milk with protein powder stirred in. McGill’s Office for Science and Society explains the process. Milk passes through membranes that separate lactose, minerals and water from the larger milk proteins. The producer then adds more milk protein back. The article puts the result at 18 g of protein per serving against about 8 g in regular milk.

Brands get there in different ways. Dairyland, a Canadian brand, sells two kinds. Its 2% Ultrafiltered Milk lists ultrafiltered partly skimmed milk and two vitamins, though the page copy calls it enriched with milk protein concentrate. Its 2% Protein Beverage lists skim milk, water, milk protein concentrate, cream, lactase, corn starch and carrageenan among other things. Both claim 18 g per 250 mL. Two cartons that say high protein can be different products, so read the list.

How much more protein does high protein milk have?

About 5 g more per cup, which is 13 g against 8.1 g in a cup of 2% milk. I put five milks from USDA FoodData Central next to the two fairlife labels, with a cup as the serving. Protein per 100 kcal is my own division of the printed numbers.

Milk	Serving	Protein	Fat	Sugars	Energy	Protein per 100 kcal
Milk, whole, 3.25%	244 g (1 cup)	7.7 g	7.9 g	12.3 g	149 kcal	5.2 g
Milk, 2%	244 g (1 cup)	8.1 g	4.8 g	12.3 g	122 kcal	6.6 g
Milk, 1%	244 g (1 cup)	8.2 g	2.4 g	12.7 g	102 kcal	8.0 g
Milk, nonfat	247 g (1 cup)	8.4 g	0.4 g	12.0 g	86 kcal	9.8 g
Milk, 2%, protein fortified	246 g (1 cup)	9.7 g	4.9 g	12.9 g	138 kcal	7.0 g
fairlife 2% ultra-filtered	240 mL (1 cup)	13.0 g	4.5 g	6.0 g	120 kcal	10.8 g
fairlife fat-free ultra-filtered	240 mL (1 cup)	13.0 g	0.0 g	6.0 g	80 kcal	16.3 g

The fairlife page puts its cup next to regular milk: 13 g of protein against 8 g, and 6 g of sugar against 12 g. The USDA records agree. Against 2% milk the protein is about 60% more, and the sugars are 51% lower, 6.0 g against 12.3 g. The calories match, 120 kcal for the filtered 2% and 122 kcal for the regular one, so the extra protein doesn’t cost energy. The fat-free pair makes the same point. The filtered cup has 13 g of protein and 80 kcal, while a cup of regular skim milk has 8.4 g and 86 kcal.

Fortified milk is another route. The protein-fortified 2% record reaches 9.7 g a cup, 1.6 g above plain 2%, and ultrafiltration goes much further.

What does it add up to in a day? The Dietary Guidelines for Americans set a dairy goal of 3 servings a day in a 2,000 kcal pattern. Call a serving a cup. Three cups of fairlife 2% then give 39 g of protein, and three cups of regular 2% milk give about 24 g. That’s roughly 15 g more for 360 kcal against 366, a real share of how much protein you need a day.

Is there high protein milk in Canada?

Yes. Dairyland’s protein line is the clearest example I found, with 18 g of protein per 250 mL serving. Its protein page claims 2X more protein than its regular milk. The line includes ultrafiltered milk in 0%, 2% and 3.25%, protein beverages in 1%, 2% and 3.25%, and chocolate versions of both. The ultrafiltered milk comes in 1 L bottles and the protein beverages in 1.89 L cartons, with a 4 L jug for the 2%.

The serving sizes differ, so compare per 100 mL. Regular 2% milk has about 3.4 g, since a 240 mL cup holds 8.1 g. The fairlife cup comes to 5.4 g per 100 mL, and the Dairyland serving comes to 7.2 g. Per millilitre, Dairyland carries about a third more protein than fairlife.

I checked the 2X claim against the USDA record, not against Dairyland’s own regular milk. A 250 mL glass of 2% milk would hold about 8.4 g, scaling the 8.1 g cup, and 18 g is 2.1 times that. One gap remains: Dairyland’s calories and sugars sit in an image on its pages that I couldn’t read, so I left them out. Compare them on the carton.

Not every filtered milk is high protein. Natrel’s fine-filtered milk is sold in skim, 1%, 2% and 3.25% in Canada, and its page makes no protein or sugar claim. The only comparison on it is about staying fresh. So “filtered” on a carton doesn’t promise protein.

Is high protein milk worth buying?

If you drink a cup of milk a day, fairlife 2% is an easy way to add about 5 g of protein without adding calories. The sugar drop is a bonus. McGill’s piece is blunter, saying most people don’t need the extra protein and gain little by paying more for it. I’d skip it if you don’t drink milk, because 13 g from a drink you don’t like isn’t a plan. Eggs, yogurt or tofu will get you there with food you do like. Milk is also the base of most high protein shakes.

Plant milks differ a lot. Per 100 g, unsweetened soy milk has 3.55 g of protein, close to cow’s milk. Oat milk has 0.80 g and almond milk has 0.55 g.

High protein milk is still milk, so it doesn’t suit a milk allergy, and lactose-free changes nothing there. With kidney disease your doctor sets the protein figure. This guide covers adults only.

Labels change, and I read these pages. Log the carton you actually drink. If its barcode comes up empty in Calsa, a photo of the nutrition label fills the gap.
