The Problem With Whey

What Whey Doesn't Have

Two sides of the same problem, what it costs the planet, and what it costs you.

The Ecological Cost
  • High CO2 emissions
  • Vast amounts of animals required
  • Heavy land use
  • High water consumption
The Personal Cost
  • Bloating from high RNA content
  • Gas and digestive discomfort
  • Acne-forming
  • Dairy and lactose sensitivity

The Technology

From Yeast to Isolate

The full production process behind our Yeast Protein Isolate No cows, no farmland, just fermentation.

Step 1
Fermentation

Yeast cultures are fermented under controlled conditions, growing a complete protein without any animal or dairy input.

Step 2
Separation

The protein is separated from the fermentation broth, removing everything that isn't protein.

Step 3
Isolation

Further purification concentrates the protein into a clean isolate with a whey-identical amino acid profile.

Step 4
Drying

The isolate is gently dried into a fine, soluble powder, ready to blend without clumping or grit.

Step 5
Packaging

Blended with flavor, packed, and shipped. A complete protein with zero land or animals required.

Build and Recover, Faster

Yeast Protein is naturally rich in Branched Chain Amino Acids (BCAAs), which help prevent muscle loss and support post-exercise recovery.

Tests show BCAA content comparable to whey protein concentrate, and higher than pea protein isolate.

Clinically Matched with Whey

Participants: 116 healthy men aged 40+ were enrolled; 79 completed the study.

Intervention: Subjects consumed 40g of Yeast Protein, whey protein, or placebo (maltodextrin) twice daily for 8 weeks.

Results: Both the Yeast Protein and whey groups showed significant increases in lean trunk and total lean mass.
