BN Protein Pure — Instantised Whey Protein Isolate

The cleanest WPI we could make. Nothing added, nothing hidden.

BN Protein Pure delivers 27.6g of instantised whey protein isolate per 30g serve — completely tasteless, virtually carb-free, and with just 0.09g of lactose per serve, making it exceptionally easy to tolerate for those who struggle with standard whey proteins.

Sourced from grass-fed whey and instantised, BN Protein Pure dissolves cleanly into water, hot drinks, smoothies, or food without clumping or aftertaste.

One ingredient. No flavours. No sweeteners. No fillers.

Why protein quality matters

Not all protein is equal. With a PDCAAS score of 1.00 — the highest possible rating for protein quality — BN Protein Pure delivers a complete essential amino acid profile, including 14.3g of leucine per 100g of protein.

Leucine is the primary amino acid signal for muscle protein synthesis, making it particularly important for muscle retention, recovery, and lean mass support — especially during periods of reduced intake or increased demand.

Per 30g serve: 27.6g protein · 0.1g carbohydrates · 0.3g fat · 481kJ · 0g gluten

Gluten free · Low lactose · Non-GMO · Halal certified ·
