How much does 30 g of whey protein cost in South Africa?
The table ranks products by Rand per 30 g of protein: tub price divided by (tub weight, divided by serving weight, multiplied by protein per serving), multiplied by 30. Prices are from brand shops or Dis-Chem Living Fit, October 2026.
| Product | Type | Price | Serving / protein | R per 30 g protein |
|---|---|---|---|---|
| USN Hydrotech 900 g | whey and wheat protein matrix | R369–R418 | 30 g / 20 g | R18–R21 |
| NPL Platinum Whey Plus 1 kg | whey with pea, rice, egg | R490 | 40 g / 25 g | R23.50 |
| NPL Anabolic Whey 908 g | whey with soy and pea | R480 | 43 g / 27.6 g | R24.70 |
| USN BlueLab 1 kg | whey blend | R689 | 32 g / 23.6 g | R28.00 |
| Primal Whey 750 g | concentrate, isolate, hydrolysate | R540–R740 | 30 g / 21 g | R31–R42 |
| NPL Platinum Whey 908 g | whey blend | R700 | 32 g / 22.5 g | R32.90 |
| USN Isozero 805 g | isolate | R899–R910 | 23 g / 20 g | R38.50–R39 |
| Lifestyle Food WPC 500 g | single-ingredient concentrate | R500 | 20 g / 15.2 g | R39.50 |
| Biogen Iso Whey Premium 750 g | blend (ingredients include concentrate) | R765 | 30 g / 20.9 g | R44 |
| NPL 100% Whey Isolate 700 g | isolate | R900 | 25 g / 19.9 g | R48.50 |
| Myprotein Impact Whey 1 kg | concentrate | R1 300 | 30 g / 23 g | R51 |
Primal's price differs between its product page and category listing, hence the band. Evox Whey Advanced (R670 for 908 g) is left out because its Dis-Chem page lists 23 g protein but no scoop weight.
What does the table tell you?
Blends beat isolates on price per gram of protein, usually by 30–60%. Isolates cost more because they are filtered further and carry more protein per scoop, not because they build more muscle per gram. Pure whey is not the cheapest source here: the two lowest rows include wheat, pea, rice, soy or egg protein, so read whey blend vs isolate before buying on price alone. USN Hardcore Whey gH lists 27 g in a 33 g scoop at R449 per kg, which would be cheaper still, but that density alongside added creatine looks high, so we left it out until the label is verified.
Where do ATP Fitness products fit?
ATP Fitness's shop and Takealot listings did not publish serving size or protein per serving on 27 October 2026, so ATP cannot be ranked on this metric. Per 100 g of powder (not comparable with protein cost), ATP's unflavoured concentrate is R80 in the shop and about R64 on Takealot (undated PriceCheck snapshot), its isolates are R112–R131, against R100 for Lifestyle Food's concentrate and R130 for Myprotein.
Can you trust the label numbers?
Only partly. South African testing found most sampled products differing from their labelled protein, so treat the table as the best case (how protein is measured). Compare against the cheapest whey per serving answer and the best whey protein and best whey isolate pages.
