THORNE - Whey Protein Isolate - Balanced Amino Acids Profile…

Checked against public sources between July 26 and September 2, 2026 · LookCloser does not sell or recommend supplements.

Does the marketing hold up?

Ingredient amounts are hidden inside “Proprietary Blend”. A blend total may be legal, but it prevents you from knowing whether any individual ingredient reaches a meaningful amount.

“Couldn’t verify” means we looked and found no public proof — not a mark against the product. Most supplement claims cannot be independently verified by anyone, so grey is the normal state of this industry.

Ingredient amounts are hidden inside “Proprietary Blend”

A blend total may be legal, but it prevents you from knowing whether any individual ingredient reaches a meaningful amount.

Evidence and sources

The panel lists “Proprietary Blend” (30 mg) as a combined amount. A blend total can’t tell you whether any single ingredient reaches a dose used in research.

Research behind the findings

Dose and research context

We could not match an amount on this product to a studied range for the same ingredient, so these links are ingredient background rather than a measurement of this product.

Background reading

What the research says about these amounts

Not a score. Studies disagree with each other and change over time, so this sits beside the evidence rather than counting toward it — it is here so you can read the sources yourself.

The panel lists 1 g of prebiotic fiber (inulin-type) per serving. Studies we found used 3 g–10 g a day, so this sits below that range.

0studied 3 g–10 g

Study ranges differ between trials and change as research changes. This is background reading, not a pass, a failure, or a recommendation.
