Yeast Protein vs Whey vs Plant Protein
Choose best according to you. All 3 have their pros and cons.
Comparison – Yeast Protein | Whey Protein | Plant Protein
| What Actually Matters | Yeast Protein Isolate | Whey Protein | Plant Protein |
|---|---|---|---|
| Source | Fermented yeast-derived protein | Milk-derived protein | Blend of pea, brown rice, soy, faba beans |
| Dairy-based | No | Yes | No |
| Lactose concern | No lactose | Whey concentrate may bother lactose-sensitive users. Whey isolate is usually easier. | No lactose |
| Amino acid profile | Strong amino acid profile, closer to whey (9.5/10) | Benchmark protein quality (10/10) | Varies sharply by blend used (7.5/10) |
| Protein Absorption (PDCAAS score) | 1 | 1 | 0.7–0.9 depending on blend used |
| Protein Absorption (DIAAS score) | Around 1.02 (102%) | Concentrate: around 1.07 (107%) Isolate: around 1.09 (109%) |
0.8 (80%) – 1 (100%) depending on blend used |
| Digestibility | Gut friendly, non-dairy advantage for people avoiding milk proteins | Fast-digesting and efficient if dairy suits you. Whey concentrate may feel heavy for lactose-sensitive users. | Can be good, but digestibility and heaviness depend a lot on the blend used. |
