Product details
Where this label sits
Transparent Labs 100% Grass-Fed Whey Protein Isolate is one of the protein powders in the Scoop Sense database. Every active ingredient on the panel is listed with its own dose — nothing is hidden inside a blend total. It runs 30 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
- Grass-fed whey protein isolate · 28 g. Roughly 88% protein by scoop weight; whey isolate is well studied for supporting muscle protein synthesis after resistance exercise.
- Stevia leaf extract (flavored tubs only) · amount not stated on label. Plant-derived zero-calorie sweetener; the unflavored tub omits sweeteners entirely.
Flavors & sweetener
Figures verified against the Unflavored tub (28 g protein per 32 g scoop, 30 servings); flavored versions use stevia and run a 34-36 g scoop depending on flavor.
Who it's best for
A lean-ratio pick — at least 80% of each scoop is protein, which suits anyone counting calories closely. 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.

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.

Common questions about Transparent Labs 100% Grass-Fed Whey Protein Isolate
How much of a Transparent Labs 100% Grass-Fed Whey Protein Isolate scoop is actually protein?
28 g of protein from a 32 g serving — about 88%. The rest is flavoring, fats, carbs, and whatever else the label lists. A higher percentage means less filler per scoop.
Does Transparent Labs 100% Grass-Fed Whey Protein Isolate disclose every dose?
Yes — the label lists an individual amount for each ingredient, with no proprietary blends. That is what the "label fully disclosed" tag on Scoop Sense means, and it is what lets each dose be compared against the amounts used in published research.
