Cheapest Whey Protein per Gram of Protein (2026)
The Cheapest Whey Protein
You want to buy whey protein without overpaying. Smart. But cheap per kilo is not the same as cheap per gram of protein.
A €30 bag with 60% protein is more expensive than a €40 bag with 85% protein. We did the math.
Top 5 Cheapest Whey (Per Gram Protein)
| Product | Price/g protein | Protein% |
|---|---|---|
| Bulk Natural Pure Whey | €0.019 | 73% |
| CN Supplements Whey | €0.019 | 76% |
| Bulk Hydrolysed Isolate | €0.028 | 80% |
| Bulk Pure Whey | €0.029 | 76% |
| XXL Perfect Whey | €0.032 | 79% |
Why Price Per Gram?
Bag A: €40 for 1kg at 70% = 700g protein = €0.057/g
Bag B: €55 for 2.5kg at 80% = 2000g protein = €0.028/g
Bag B seems more expensive but is twice as cheap per gram.
The Math
At 2 shakes/day (50g protein):
Cheapest (€0.019/g): €28.50/month — €342/year
Average (€0.040/g): €60/month — €720/year
Difference: €378 per year
