Protein · Answer
Among the listings we checked, ATP Fitness Unflavoured Whey Protein Isolate is one unflavoured isolate in South Africa with a one-ingredient list: single-ingredient, no sweeteners, 800 g for R900 at the ATP shop or R699 on Takealot (undated PriceCheck snapshot, October 2026). The shop had it out of stock on 27 October 2026, and ATP does not publish protein per serving, so a concentrate is the budget alternative.
Unflavoured isolate is a small niche here: most local isolates ship in sweetened flavours. Prices are October 2026.
| Product | Size and price | Notes |
|---|---|---|
| ATP Fitness Unflavoured WPI | 800 g, R900 (ATP shop); R699 (Takealot, PriceCheck snapshot) | single ingredient, no sweeteners; out of stock on the shop on 27 October 2026 |
| ATP Fitness Grass-fed Unflavoured WPI | 800 g, R779 to R1 000 (Takealot) | found on Takealot only; two snapshots disagree |
| Lifestyle Food Whey Concentrate Unflavoured | 500 g, R500 (Dis-Chem Living Fit) | concentrate, not isolate; 15.2 g protein per 20 g |
| ATP Fitness Unflavoured WPC | 1 kg, R800 (Takealot R639, undated PriceCheck snapshot) | cheaper concentrate option |
We did not find an unflavoured USN, NPL or Primal isolate in the sources checked; their isolates are sold in flavours (USN Isozero in three, Primal in two, both sweetened or with sweeteners not named).
ATP does not publish protein per serving, so we cannot give a verified figure. Per 100 g of powder, the unflavoured isolate is R112.50 at the shop (about R87 at the Takealot snapshot price), close to USN Isozero at R112 per 100 g. The Takealot price is notably lower, so compare both before paying R900.
Shake it with cold milk or maas rather than water. Add banana, cocoa, cinnamon or peanut butter. For baking, add it to pancake or muffin batter; protein survives heat, though texture changes and high temperatures can dry baked goods. Isolate mixes thinner than concentrate and dissolves easily, which suits clear soups and smoothies.
A credible alternative for a documented isolate is USN Isozero (R899 to R909.99, 20 g protein per 23 g scoop), though it is flavoured.
Isolate has less lactose but is still milk protein; avoid it with a milk allergy and check with a doctor if you have kidney disease or are under 18.
