Nutrex IsoFit 100% Whey Isolate Protein
Nutrex IsoFit — Premium Whey Isolate That Tastes Like Dessert
IsoFit is Nutrex's flagship protein: high-purity, fast-absorbing whey isolate with a clean macro profile — low fat, low carbs, rich in BCAAs — and dessert-grade flavours like Blueberry Lemonade and Blood Orange that make hitting your protein target the easiest part of the day. 2lb / 30 serves, in stock at TopDog Nutrition.
Key Benefits
- High-purity whey isolate — fast uptake for post-workout recovery.
- Clean macros — low in fat and carbs, easy to fit any nutrition plan.
- Rich in BCAAs — supports muscle protein synthesis and repair.
- Genuinely great flavours — smooth mixing, dessert-level taste.
Build the Recovery Stack
Add Creatine Drive to the same shake (or grab the IsoFit + Creatine stack), and sip EAA + Hydration during training for the complete Nutrex performance routine.
Directions
Mix one scoop with water or milk after training or between meals. Use daily to hit your protein target — recovery is built on consistency.
Frequently Asked Questions
Why isolate over a standard whey blend?
Faster absorption and cleaner macros — isolate carries less lactose, fat and carbs per serve, which matters most post-workout and during a cut.
