🥛 From whole milk to hydrolysed whey – the protein journey
⚖️ How much protein is actually in that tub?
Many flavoured “90% WPI” products contain only ~81g protein per 100g powder because flavours, gums, and inulin displace protein. Always check “protein per 100g” – not the front label.
| Label claim | Real protein per 100g | Reason |
|---|---|---|
| WPI90 (flavoured) | 81g | Flavours, organic inulin, gum, stevia add mass |
| WPI (unflavoured) | ~89‑93g | No fillers; only sunflower lecithin |
| WPC (flavoured) | ~70‑75g | Lower starting protein + flavour additives |
| Hydrolysed WPI (unflavoured) | ~92‑94g | Minimal processing aids |

📚 Learn the truth (science‑based)
Processing methods: MF/UF vs IE vs Hydrolysis
Cold microfiltration preserves lactoferrin & immunoglobulins. Ion exchange denatures them. Hydrolysis gives fast absorption but loses immune fractions.
Whey economics: why $68/kg is fair
Whey is a cheese by‑product → raw cost $5‑15/kg. Realistic WPI production cost: $46‑89/kg.
Testing badges decoded
HASTA tests banned substances (NOT heavy metals). Informed Sport similar. Clean Label Project tests heavy metals.
Amino spiking: detect protein fraud
Avoid products with added taurine, creatine or glycine >2% of protein – inflates nitrogen scores.
