Formula & tolerance checks
Smooth Vanilla is not an unsweetened option merely because added sugar is zero.

A concrete difference in the label
The US Smooth Vanilla ingredient list names pea protein isolate, natural flavors and thaumatin. That gives a more useful comparison than the broad word clean. It is a flavored source-specific formula, not the same ingredient list as a plain pea powder.
What the serving information actually describes
The cited Smooth Vanilla panel identifies a 25 g, two-scoop serving with 20 g protein. Those values belong to that panel. The product family includes Just Natural, chocolate and other flavors, so do not move the figures across options without checking.
The sweetener question
The presence of thaumatin is why we do not use no added sugar as a synonym for unsweetened. For someone who wants no added sweetness, the next step is checking the separate Just Natural panel rather than assuming every Clean Lean Protein version meets that preference.
What to do with digestive promises
The manufacturer uses language about digestion. This site has not clinically tested that outcome or reviewed a representative set of purchaser experiences. A source and ingredient comparison remains useful without turning the promise into a guarantee.
A fair shortlist comparison
Place Smooth Vanilla beside a single-ingredient Naked Pea option only if you recognize that flavoring and sweetening are changing too. Compare it with Ora or KOS if your decision involves a source-specific formula versus a broader blend.
We reviewed the manufacturer’s product information and the identity of the version discussed. We have not independently tested the powder, its taste, contaminants or digestive effects. No numerical score or customer-review rating is assigned. Read our method.
Which alternative is worth comparing?
| Alternative | Why compare it? |

What the formula details change
| Detail | Manufacturer information | Buying implication / limit |
|---|---|---|
| Pea protein isolate | Named in the US Smooth Vanilla list. | Different from a multiple-protein-source blend. |

| Flavor-specific panel | Smooth Vanilla is the panel examined. | No nutritional numbers are transferred to Just Natural. |

Questions about this formula
Does zero added sugar make Smooth Vanilla unsweetened?
No. Its cited ingredient list includes thaumatin; sugar and sweetening are different checks.
Are the Smooth Vanilla numbers valid for Just Natural?
