Comparisons / Isopure Zero Carb 100% Whey Protein Isolate vs Fast&Up Whey Isolate

Isopure Zero Carb 100% Whey Protein Isolate vs Fast&Up Whey Isolate

**Verdict: Isopure Zero Carb edges ahead, but the price premium is steep** Isopure Zero Carb scores 5.2/10 versus Fast&Up's 4.8/10 – a marginal 0.4-point difference that comes at a significant cost premium of ₹207.78 per serving. **Why Isopure scores higher:** Its formula rating of 5.6 crushes Fast&Up's 1.5, driven by comprehensive micronutrient fortification. You get 190.625mg Vitamin C, 21.875mg Zinc, 90.625mcg Selenium, and full-spectrum B vitamins – essentially a multivitamin built into your protein. Transparency is perfect (10.0) for both brands. **The trade-off:** Fast&Up delivers superior dosing (6.0 vs 3.9) with 83.871g protein per serving versus Isopure's 78.125g – that's 5.7g more protein. It's also 48% cheaper and contains slightly less fat (0.4839g vs 3.125g). However, Fast&Up lists 8.3548g total sugars, which contradicts its "zero carb" positioning. **Recommendation:** Choose Isopure if you want added micronutrients and can justify ₹634.98/serving. Choose Fast&Up if you prioritize pure protein content and value, saving ₹6,216 per 30 servings while accepting a basic formula without vitamin fortification.
