Clear ingredient deck, grass-fed source, no artificial flavors or sweeteners. One of the cleaner whey isolates if you read labels carefully. Vanilla and Mocha both pull off the difficult job of being palatable without sucralose.

What it is

Transparent Labs Grass-Fed Whey Protein Isolate is a category-leading product in the protein space. Editorially-selected for protein-powder, clean-label use cases. The label declares third-party testing where applicable.

Suggested use

Follow label dosing. As with any supplement, talk to a clinician before starting if you take prescription medications or have a chronic condition.

A note on selection

We list products that have a real track record (years of use, real users, published research where available) and avoid the wellness-aisle proprietary blends that hide doses behind 'patented formula' language.
