Buying guide
Compare the shake, then the case
Bottle price is a good starting point for the shake you already buy. Across formulas, look at how much protein and how many calories each bottle supplies.
Work out the cost per bottle
Divide package price by the number of bottles or cartons. For a case of four 3-packs, count all 12. Then check the volume of each container and the flavors in an assortment.
For a new shake, try a single bottle or smaller pack before buying a case.
Fairlife’s product lines have different protein amounts
| Manufacturer’s line | Listed protein per serving |
|---|---|
| Core Power | 26 g |
| Core Power Elite | 42 g |
| Nutrition Plan | 30 g |
Fairlife lists these amounts for its lines. Check the current label for the flavor and container in the retailer’s offer.
Compare the cost of a protein amount
To compare across formulas, divide case price by total grams of labeled protein: bottle count × protein per bottle. Multiply by 20 if you want a cost per 20 g comparison. This is shopping arithmetic, not a recommended serving.
Calories, sugar, and ingredients still matter to the drink you choose. A higher protein figure doesn’t settle those choices.
Check the protein source and allergens
Read the ingredient and allergen statements on the exact drink. A lactose-free dairy shake still contains milk protein. Fairlife describes Core Power as milk-based even though it is lactose-free.
A protein shake and a meal-replacement product can have different intended uses. Fairlife specifically says Core Power is not a meal replacement; use the label for other lines rather than treating all bottled shakes alike.
