What the numbers say
Nutrition Plan vs Core Power 26g is the lopsided matchup. The two bottles are close in calories (150 vs 170), but Nutrition Plan has 4 g more protein and 20 fewer calories. On the label numbers alone, there's no trade-off to weigh.
Core Power 42g is the bigger serving, not the leaner one. It adds 12 g of protein over Nutrition Plan for 80 more calories. Those extra grams come in at 15.0 g per 100 calories, below Nutrition Plan's 20.0, which is why the big bottle's overall score (18.3) sits a step behind. It makes sense when you want one large serving; it isn't the efficient pick.
Inside the Core Power line, 42g beats 26g. Both are listed as 1 bottle (14 fl oz), but the 42g bottle has 16 g more protein for 60 more calories, lifting the score from 15.3 to 18.3. On price, we only have Amazon 12-pack prices for Core Power 42g ($4.00–$4.75 a bottle), so we can't compare cost against Nutrition Plan yet.
Which one should you pick?
- Calories are your budget: fairlife Nutrition Plan (20.0 g protein per 100 calories).
- Most protein in one serving: fairlife Core Power 42g (42 g).
- Price: we've only confirmed a price for fairlife Core Power 42g ($4.00–$4.75 a serving, $0.95–$1.13 per 10 g of protein), so we can't call a value winner yet.
