IsaPro Whey Protein
Protein booster meant to be added to a shake, not to replace one.

Why Isagenix makes this one
What it was built to do
Originally created to add protein to a shake without adding carbs, fat or calories.
What actually makes it different
18g undenatured whey concentrate at 90 calories, virtually carb- and fat-free; lowest calories per gram of protein.
Who it suits
Stirred into oatmeal, smoothies, baked goods or a shake.
The dividing line
Performance Protein: one IsaPro scoop plus 1.5 IsaLean scoops approximates it with fewer carbs.
What the system-level research shows
Several published trials involve these products, funded by unrestricted Isagenix grants with company employees or advisers among the authors. They test a whole protocol — protein pacing with calorie restriction or intermittent fasting — not a single shake. In one head-to-head over eight weeks the protein-pacing group lost more weight and more visceral fat than a heart-healthy comparison diet, and reported lower desire to eat. In a 52-week follow-up the control group trended back toward baseline on most markers despite a lower average calorie intake. Those are findings about a programme. They are not evidence that this one product, bought on its own, produces that result, and this site will not present them that way.
Where the brand does not explain itself
This product and Clear Protein overlap enough that most buyers ask which one they need. Isagenix publishes no rationale for both existing and no guidance on choosing between them. We are not going to invent one. What we can tell you is what actually differs, which is the dividing line above — and that if the brand had a cleaner answer, it would be on their page and not only on ours.
