🥛 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.

📚 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.
