Source: Nutrition Facts image on the Amazon listing and the Core Power Chocolate 26g page on fairlife.com, read Sep 30, 2026. Cost: $41.88 for 12 bottles = $3.49 each (about $0.13 per gram of protein). Protein is the amber cell because it is the headline number on the bottle; the label gives no caffeine amount, though cocoa is an ingredient.
Not built as a pre-session meal; it is filed here as an after-session drink.
Not a during-session drink; water or a carbohydrate drink belongs there.
A ready protein serving for after a session when a meal is still a while off.
Not a stand-in for water or meals through the day.
Scouting report
Facts, not hypeStrengths
- 26 g of protein from milk as the first ingredient, per the label.
- 0 g added sugars; 5 g total sugars, none of them added.
- 860 mg potassium and 670 mg calcium per bottle (20% and 50% DV).
- Aseptically pasteurized; the directions ask for refrigeration after opening.
Limits
- It is milk: the label's allergen line reads "Contains: Milk."
- Four sweeteners on the ingredient list: monk fruit juice concentrate, stevia leaf extract, acesulfame potassium and sucralose.
- $3.49 a bottle, the priciest protein per gram of the three After entries on this scoreboard.
- 3 g of saturated fat (15% DV), more than the other shake here.
Best use
- After a session when you want something ready to drink and will not eat for a few hours.
- A glass of ordinary milk with a meal covers much of the same ground for less money.
What the label shows
We read the Nutrition Facts and ingredient panel pictured on the Amazon listing on Sep 30, 2026, and compared them with the Core Power Chocolate 26g page on fairlife.com; the numbers matched [1][2].
| Nutrient or ingredient | Per serving | What to know |
|---|---|---|
| Calories | 170 | One 14 fl oz (414 mL) bottle is one serving. |
| Protein | 26 g (52% DV) | From filtered low-fat grade A milk, the first ingredient. |
| Total carbohydrate | 8 g | 2 g dietary fiber, 5 g total sugars, 0 g added sugars. |
| Total fat | 4.5 g | 3 g saturated (15% DV), 0 g trans; cholesterol 30 mg. |
| Sodium | 260 mg (11% DV) | The listing tags it "low sodium"; the label itself does not make that claim, so we don't either. |
| Potassium | 860 mg (20% DV) | Far more than the Premier bottle's 320 mg; calcium (50% DV) is the larger share by percentage. |
| Calcium | 670 mg (50% DV) | Also listed: iron 1.4 mg (8%), vitamin D 5 mcg (25%), vitamin A 240 mcg (25%). |
| Sweeteners | 4 listed | Monk fruit juice concentrate, stevia leaf extract, acesulfame potassium, sucralose. |
| Lactase enzyme | Listed | An enzyme that breaks down milk sugar (lactose). |
| Allergen | Milk | "Contains: Milk." |
One discrepancy: the ingredient text typed into the Amazon listing also names maltodextrin, which does not appear on the label image on the same listing or on fairlife.com. Packaging can change between production runs, so read the bottle you receive.
What the evidence shows
Ultra-filtration, plainly. fairlife describes its process as flowing milk through soft filters to concentrate the protein and calcium and filter out most of the sugar [3]. That is the brand's explanation for how a milk-based bottle reaches 26 g of protein with 5 g of sugar. The label lists lactase enzyme, and the Amazon listing's description and attributes call it "lactose free." We did not find that wording on the label image or on the fairlife.com Core Power pages we opened [4], so we report it only as a listing claim.
Is 26 g a sensible serving? The International Society of Sports Nutrition (ISSN) position stand on protein and exercise gives a general per-serving figure of about 0.25 g of high-quality protein per kilogram of body weight, or 20–40 g, spread every 3–4 hours, and a daily range of 1.4–2.0 g/kg for most exercising people [5]. It notes that dairy proteins are among the richest in the essential amino acids, and that whole foods can meet these needs, with supplements as a practical shortcut [5]. So a bottle is a reasonable single serving, and a glass of milk with a meal does much the same job.
Sodium and potassium. The brand's site markets Core Power with electrolytes. By the numbers, one bottle carries 260 mg sodium and 860 mg potassium. That is useful context, not a hydration plan: the fluid you lose in a long, hot session is replaced mainly by drinking, and the sweat-and-sodium explainer covers the guidance.
Caffeine. No caffeine amount appears on the label. The FDA notes that when a food contains an ingredient that naturally carries caffeine, such as chocolate, caffeine itself is not listed separately [6]; this bottle lists alkalized cocoa. Oddly, the Amazon listing's attribute field reads "Caffeinated." We could not find a caffeine figure from the brand.
Lactase-treated milk is still milk. People with a milk allergy should not drink it, whatever the lactose content [7]. Anyone who has been told to limit potassium should note the 860 mg per bottle and ask a clinician first.
Game plan: using it in a session
A sequence for fitting one bottle into a normal training day, not a promise about results.
Store it before opening
The bottle is aseptically pasteurized and the directions ask for refrigeration after opening; the listing gives a 270-day shelf life.
Drink water during the session
For an hour or so of exercise, plain water is the in-session drink.
Decide whether you need it
If a meal with milk, eggs, fish, meat, beans or tofu is coming soon, skip the bottle. If it is hours away, one bottle is one 26 g serving.
Shake and drink
The label says to shake well before use. Refrigerate any leftover.
Price and where it is sold
On Sep 30, 2026 the Amazon listing for Core Power Chocolate, 14 fl oz, pack of 12, showed $41.88 for a one-time purchase, shipped and sold by Amazon.com, in stock ($3.49 per bottle). A lower Subscribe & Save price was also shown; we used the one-time price. The listing marked it "Non-returnable due to food safety reasons." Check the live page before buying: Core Power Chocolate 12-pack on Amazon.
On the same day, the Premier Protein Chocolate bottle worked out to $2.23 for 30 g of protein, and a scoop of Optimum Nutrition Gold Standard Whey to $1.39 for 24 g before any milk.
Who should look elsewhere
- Anyone with a milk allergy, or anyone avoiding dairy for any reason.
- Anyone told to limit potassium, protein or saturated fat, or who takes prescription medicines, should ask a clinician or pharmacist first.
- Anyone who avoids non-nutritive sweeteners such as sucralose or acesulfame potassium.
- Anyone who wants more protein per bottle: fairlife sells a separate 42 g Core Power line, not covered here.
