100% Grass-Fed Whey Protein Isolate

Quality & Materials
Sourced from New Zealand grass-fed cattle; no soy lecithin (uses sunflower lecithin); zero artificial sweeteners or food dyes.
Evidence & Testing
Third-party tested by Informed Choice; protein content is verified to match label claims exactly with no amino spiking.
Brand Transparency
Industry leader in transparency; users can look up the specific lab results for their batch number on the website.
Value Assessment
Priced competitively for grass-fed isolate at $1.99/serving, offering superior purity compared to standard isolates.
Why Not Alternatives?
Most 'grass-fed' brands do not provide actual lab results for heavy metals on a batch-by-batch basis. Transparent Labs also avoids all artificial colors and preservatives found in brands like BSN or MuscleTech.
