Quest Vanilla Protein Shake (11 fl oz): 30g Protein, Labelgrade B-

Labelgrade: B- 73 / 100 — Same 30 g protein / 159 calorie hit as Premier Protein but with a notably shorter ingredient list (10 ingredients vs ~30) and a single sweetener (sucralose only, no acesulfame potassium). The trade-off vs Premier: no comprehensive vitamin-mineral premix and a smaller bottle (11 fl oz vs 11.5 fl oz). If you want one of the engineered high-protein shakes with the cleanest formulation, this is the choice.

The short answer

Quest Vanilla Protein Shake delivers 30 g of protein in 159 calories per 11 fl oz (325 mL) bottle (USDA FDC 2339950) — matching Premier Protein on macros while using a shorter ingredient list (10 ingredients vs ~30) and a single sweetener (sucralose only). The Labelgrade is B- (73 / 100) — the highest-scoring RTD shake in our database so far, on the strength of the cleaner formulation. Per-bottle protein density and per-mL density are virtually identical to Premier; the ingredient-quality margin is what separates them.

Why this Labelgrade

DimensionGradeScoreWhy
Protein densityC64 / 1009.2 g of protein per 100 mL — comparable to all RTD shakes. The 30-g-per-bottle number is what matters, not the per-mL density
Ingredient qualityB-72 / 10010 ingredients total: water, milk protein concentrate, sunflower oil, natural flavors, sunflower lecithin, salt, two phosphates (sodium polyphosphate + trisodium phosphate), gellan gum, sucralose. Engineered but minimal compared to Premier — and zero acesulfame potassium
Sugar loadA+95 / 1001 g sugar, 0 g added — among the lowest in packaged foods
Sodium loadA-85 / 100250 mg per shake (77 mg per 100 mL) — low, comparable to plain milk
FiberF30 / 1000 g — RTD shakes typically have no fiber
OverallB-73 / 100The cleanest of the major engineered RTD shakes. If you’ve decided you want an artificially-sweetened high-protein convenience drink, Quest’s 10-ingredient formulation is the lowest-additive choice in the category

Among engineered shakes, Quest wins on ingredient simplicity. Among all 30 g-protein options, plain Greek yogurt remains the cleanest if refrigeration and a spoon aren’t problems. Premier Protein’s micronutrient premix is the main thing Quest skips.

Frequently Asked Questions

How much protein is in a Quest Vanilla Protein Shake?

30 grams of protein per 11 fl oz (325 mL) bottle (USDA FDC 2339950) — identical to Premier Protein's per-bottle protein delivery.

How many calories per shake?

159 calories per 11 fl oz bottle. Identical calorie count to Premier Protein and similar to a 180 g serving of Fage Total 0% Greek yogurt.

What sweetens it?

Sucralose, a non-nutritive sweetener. Quest uses sucralose alone, unlike Premier Protein which combines sucralose with acesulfame potassium.

How does Quest compare to Premier Protein?

Same macros (30 g protein, 159 calories, 1 g sugar) but Quest has a notably cleaner ingredient list — about 10 ingredients vs Premier's ~30. Quest uses one sweetener instead of two, skips carrageenan, and omits the extensive vitamin-mineral premix. Premier offers more added micronutrients in exchange for the longer formulation.

Does Quest contain dairy?

Yes. Milk protein concentrate is the primary protein source. The shake is not vegan and contains lactose, though the amount is very small.

Is it keto-friendly?

Yes — 3 g total carbs, 1 g sugar, 3 g fat, 30 g protein per shake fits most ketogenic and low-carb protocols.

How does it compare to Greek yogurt for protein?

Per serving: about the same protein (30 g vs Fage Total 0% at 32 g per 180 g). Per ingredient list: Greek yogurt wins decisively — Fage has 2 ingredients, Quest has 10. Per cost per gram of protein: usually similar at retail. The choice is convenience vs ingredient simplicity.

Is the calcium claim large?

Yes — 852 mg of calcium per bottle is over 65% of the FDA Daily Value (1300 mg). Most of this is naturally-occurring in the milk protein concentrate, not from added calcium carbonate.
