Product details
Where this label sits
Isopure Zero Carb Whey Protein Isolate is one of the protein powders in the Scoop Sense database. The label uses at least one proprietary blend, so a blend total stands in place of the individual amounts inside it. It runs 40 servings per container at the full labeled serving. Everything on this page comes from the manufacturer's supplement facts panel as of July 2026 — never from the marketing page.
Key ingredients & studied doses
- Whey Protein Isolate · 25 g per scoop. Ultra-filtered whey isolate is a fast-digesting, low-lactose protein source studied for supporting normal muscle protein synthesis.
- Vitamin and Mineral Blend (22 nutrients) · included per scoop. Adds nutrients such as B12, zinc, and chromium that support normal energy metabolism.
Flavors & sweetener
Creamy Vanilla is one of several Zero Carb flavors (also Dutch Chocolate, Banana Cream); all use sucralose as the sweetener with 0 g sugar and 0 g carbs per scoop.
Who it's best for
A lean-ratio pick — at least 80% of each scoop is protein, which suits anyone counting calories closely. Skip it if you want every individual dose disclosed on the label. Derived from the label figures above — not medical advice.
How we log this label
Every entry is built the same way: we read the current supplement facts panel, log each disclosed dose, compare it against the amounts used in published research, flag proprietary blends, and state the cautions plainly. The full methodology explains each step.
This label against the research
How we evaluate labelsEach bar shows the amount commonly used in published human research, and where this label's dose falls against it. Research amounts are context, not a recommendation — they are not doses, and nothing here is medical advice.
-
Protein25 g
At or above the studied amount0studied range 20 g–40 g50 g
Per-meal doses studied for muscle protein synthesis run about 20–40 g of high-quality protein, with the upper half of that range favoured for larger athletes and older adults.
Source: Jäger et al., Journal of the International Society of Sports Nutrition 2017 — “General recommendations are 0.25 g of a high-quality protein per kg of body weight, or an absolute dose of 20–40 g.”
One or more amounts on this label sit inside a proprietary blend, so the individual doses behind the blend total cannot be compared at all.
What other people say
Why we don't rate productsTwo different things, side by side: the rating the seller publishes on its own store, and what independent users write in public threads. Scoop Sense writes neither and collects no reviews of its own. Neither is evidence that a product works — they describe what people experienced and expected, not what the research shows.

What people actually report
Reddit threads about Isopure Zero Carb center on whether the premium price is justified, with newcomers repeatedly asking if it actually tastes good and at least one detailed critique calling out weak flavoring and unnecessary added ingredients.
- mixed Taste before buying. Newcomers frequently ask whether it actually tastes good before committing, reflecting isolate protein's general reputation for a chalky or medicinal taste.
- mixed Price for what you get. Threads flag it as expensive and question whether it is worth the cost compared to plainer whey isolates.
- negative Flavoring and added ingredients. One detailed comparison criticized its flavoring systems and questioned why taurine, glutamine, and extra sodium are added to what is marketed as a simple isolate.

Common questions about Isopure Zero Carb Whey Protein Isolate
How much of a Isopure Zero Carb Whey Protein Isolate scoop is actually protein?
25 g of protein from a 31 g serving — about 81%. The rest is flavoring, fats, carbs, and whatever else the label lists. A higher percentage means less filler per scoop.
What does the proprietary blend in Isopure Zero Carb Whey Protein Isolate hide?
The Vitamin and Mineral Blend (22 nutrients) lists included per scoop as a combined total. A blend total tells you the sum of its ingredients, not the individual doses inside it — which is why blend entries can't be checked against studied amounts.
