Here’s a breakdown of Rule One (R1) Whey / ISO Whey — 2 kg: what it is, what’s inside, and what to expect.



Rule One’s R1 Whey Protein Isolate (and hydrolysed-isolate blend) is a “clean” whey-protein powder: made from 100% whey isolate + hydrolyzed isolate (not whey concentrate).
It’s designed to deliver fast-absorbing, high-quality protein — good for recovery, muscle repair/growth, or if you’re watching carbs/fat and want a lean protein source.
Typical per-scoop (≈ 30–32 g) values for the isolate/hydrolyzed whey from Rule One:
| Nutrient / Component | Approx. per serving |
|---|---|
| Protein | ~ 25 g of pure whey-isolate/hydrolyzed protein |
| Carbohydrates | ~ 1–3 g carbs (low) |
| Fat | ~ 0–0.5 g fat (low) |
| Calories | ~ 100–120 kcal per scoop |
| BCAAs & EAAs | The protein is complete: includes essential amino acids and BCAAs (as standard for whey isolates) |
According to some sellers, the 2 kg tub contains around 65–76 servings (depending on batch / flavour) when using standard serving size.
R1 Whey Isolate is a good fit if you:
Want high-quality, “clean” protein with minimal carbs/fat — ideal for lean muscle building, cutting, or controlled diets.
Need fast-absorbing protein — useful post-workout or between meals when you can’t rely only on food.
Are looking for trusted supplement purity: 100% isolate + hydrolyzed isolate, no whey concentrate fillers.
Prefer a protein supplement that mixes easily and digests relatively cleanly (less lactose, less fat) compared with heavier whey-concentrate blends.
As always with supplements: this is a protein supplement, not a replacement for real food — you still need balanced diet, proper calories, training and rest.
Check the expiration date / batch / seal / authenticity when ordering — especially important if you buy online, to avoid fake or poor-quality protein tubs.
Serving size matters: if you scoop more than ~30 g per serving, protein/carbs/fat per serving will increase — so keep to recommended scoop size if your goal is to stay lean.
If you have lactose sensitivity — whey isolate tends to be easier than concentrate, but you’re still ingesting milk-derived proteins (so check tolerance).
