What are the best ready-to-drink protein shakes in South Africa?
We verified four on Dis-Chem Living Fit on 27 October 2026. Rand per 20 g of protein is price divided by grams of protein in the bottle, multiplied by 20.
| Shake | Size | Price | Protein | R per 20 g protein | Notes |
|---|---|---|---|---|---|
| USN Super M Protein Shake | 300 ml | R24.99 | 22 g | R22.72 | sucralose and added colourants; cool, dry place until opened |
| Primal Protein Shake | 350 ml | R36.99 | 25 g (170 kcal) | R29.59 | sucralose and acesulfame K; unopened shelf life not stated |
| Grenade Protein Shake | 330 ml | R59.95 | up to 25 g (under 211 kcal) | R47.96 | sucralose; out of stock when checked |
| Barebells Protein Shake | 330 ml | R59.99 | 24 g | R49.99 | sweeteners not specified; best served chilled |
All four contain cow's milk. Calorie data was missing on some pages, so we do not rank on calories.
How do shakes compare with powder and bars?
Per 20 g of protein in October 2026: powder is cheapest, at about R15.70 for NPL Platinum Whey Plus 1 kg and about R18.70 for USN BlueLab 1 kg; the cheapest RTD is about R22.70; bars run R40–R64.
| Format | Example | R per 20 g protein |
|---|---|---|
| Powder | NPL Platinum Whey Plus 1 kg (R490) | about R15.70 |
| RTD shake | USN Super M 300 ml | R22.72 |
| Protein bar | NPL 21 Protein Bar 65 g (R41.99, 21 g) | R40.00 |
| Protein bar | Biogen Iso Whey Premium Crunch Bar (R54.99, 22 g) | R50.00 |
| Protein bar | USN Trust Crunch 12 x 60 g (R600, 20 g) | R50.00 |
| Protein bar | Myprotein Layered Bar 60 g (R63.99, 20 g) | R63.99 |
A shake costs roughly 1.5 times the same protein as powder, a premium for convenience. For a bakkie, gym bag or road trip it can be worth it, but for daily use powder wins (per 30 g protein comparison).
How do you pick a shelf-stable one?
Read the label for three things: whether it says "keep in a cool, dry place" (shelf-stable until opened) or "keep chilled"; how long it lasts after opening (these pages say 12 to 24 hours, so finish it the same day); and the best-before date, which R146 requires. Do not leave a bottle in a hot car: heat degrades taste and quality, and a swollen or leaking bottle should be discarded.
What should you watch for?
- Sweeteners and colourants: the USN page lists added colourants; Primal uses two sweeteners while describing the product as "naturally sweetened", so read the ingredient list, not the front.
- Protein accuracy: South African testing found most sampled protein products differing from the label; shakes were not separately reported.
- Daily limit: Primal's page advises no more than two shakes a day.
- Allergens and health: milk allergy rules them out; check with a doctor or dietitian if you have kidney disease or are pregnant.
Which one should you choose?
For price, USN Super M; for protein per bottle, Primal; for the cleanest-looking label, we cannot rank because Barebells does not specify its sweeteners. Compare with protein bars, how to choose a protein powder and the best whey protein ranking.
