Chocolate protein shakes: compare the bottle and the country
The named Canadian bottles list 30 g and 26 g protein, with different volumes; a U.S. Premier label also shows why headline agreement is not full equivalence.
For the Canadian products below, Premier Protein Chocolate lists 30 g protein in 325 mL; Core Power Chocolate lists 26 g in 414 mL. Compare the actual bottle and country. A familiar name on a U.S. site is not proof that every Canadian label field is identical.
Start with two Canadian bottles
These are the Canadian manufacturer pages: Premier’s 325 mL chocolate shake and fairlife Core Power’s 414 mL chocolate shake. The table includes one entire source bottle of each, without coffee, milk or other additions.
| Chocolate drink | Volume (mL) | kcal | Protein (g) | Carbs (g) | Fat (g) | Total sugars (g) | Sodium (mg) |
|---|---|---|---|---|---|---|---|
| Premier Protein | 325 | 160 | 30 | 4 | 3 | 1 | 220 |
| Core Power | 414 | 170 | 26 | 8 | 4.5 | 5 | 260 |
One bottle and equal volume answer different questions
The per-bottle comparison is useful if you plan to drink the whole container. Premier lists 4 g more protein in a bottle that is 89 mL smaller. Its listed energy is 10 kcal lower. That does not mean the drinks are the same recipe or that a larger bottle is a worse choice.
For a measured 200 mL pour, the calculated Premier amount is about 98 kcal and 18.5 g protein. Core Power is about 82 kcal and 12.6 g protein. The energy ranking changes on a fixed-volume basis because the original bottles were different sizes. Say which comparison you mean before choosing a “lower-calorie” drink.
Other label fields can matter
Both Canadian bottles list 650 mg calcium, despite their different volumes. Premier lists 350 mg potassium and Core Power 850 mg. These are product-specific amounts, not a general rule about all protein shakes. Vitamins and minerals should be read on the actual bottle, including any cautions and the complete label.
Premier’s Canadian page uses a Supplemented Food Facts panel. It is not interchangeable with an ordinary U.S. Nutrition Facts panel. This article compares declared amounts and does not assess suitability for a child, a pregnancy, a medical condition or a particular treatment plan.
What happens when you open the U.S. page?
The U.S. Premier Chocolate 11.5 fl oz panel also lists 160 kcal, 30 g protein, 4 g carbohydrate and 3 g fat. However, it lists 230 mg sodium, versus 220 mg on the Canadian 325 mL panel. Saturated-fat and other fields differ too. Matching headline calories and protein are not enough to call the full formulations equivalent.
Do not copy the Canadian Core Power values to an American 26 g product, a 42 g Elite bottle or a different flavor. Each needs its own source and portion. This comparison does not claim that every retailer stocks both products or that their prices are the same.
Log the drink, then compare value if useful
Choose the country where the bottle was sold, find its exact flavor and size, and compare its panel with the package. For a partial bottle, measure the amount; half a 414 mL bottle is 207 mL, not half of 325 mL. Add any coffee syrup or other ingredients separately.
If you want a price comparison, enter your own receipt price in a single currency and use the protein for the amount bought. No current price is supplied here, so no value winner is claimed.
