Pros and cons
Core Power High Protein Milk Shake
- 26 g of protein concentrated from milk (about 80% casein, 20% whey)
- Lactose-free, gluten-free and kosher, according to fairlife
- No added sugar; 5 g of naturally occurring sugar
- Shelf-stable until opened, with 670 mg calcium and 860 mg potassium
- 4.7-star average across more than 25,000 buyer ratings
- 170 calories and 2 g fiber make it a recovery snack, not a meal
- About $3.49-$3.92 per bottle, roughly twice Premier Protein's cost per gram of protein
- Sweetened partly with sucralose and acesulfame potassium; contains carrageenan
- No third-party certification; fairlife settled animal-welfare marketing class actions in 2022
20g Plant Protein Shake
- Free from the top nine allergens, including dairy, soy and gluten
- Non-GMO Project Verified and OU kosher
- No artificial sweeteners or sugar alcohols (cane sugar and monk fruit)
- 3 g fiber plus flax oil as a plant omega-3 source
- Shelf-stable for up to 18 months before opening
- 20 g of protein counts as only 24% DV after FDA's protein-quality correction
- 4 g of added cane sugar per bottle
- Little vitamin or mineral fortification; 180 calories is snack-sized
- Brand FAQ makes sweeping, unsupported claims that whey causes health problems
Our verdicts
Core Power High Protein Milk Shake
Core Power is one of the best-tasting ways to get 26 g of real milk protein with no added sugar and no lactose. It is a recovery shake rather than a meal, so treat it as a protein boost alongside food, or choose the 42 g Elite if you want something more filling. Expect to pay roughly double Premier Protein's price per gram of protein.

20g Plant Protein Shake
OWYN is a clean, allergen-friendly vegan shake that avoids artificial sweeteners and is well liked for its smooth texture. But its plant protein scores lower on quality than dairy, it adds 4 g of cane sugar, and at 180 calories with little vitamin or mineral content it is a snack rather than a meal. Choose it for dietary restrictions rather than for value.
