Short label. Long science.
Every jar starts with double-roasted peanuts. Then the Professor adds a natural fiber that changes how much fat your body actually takes from it.
Five ingredients. Zero nonsense.
The Old School Smooth label, decoded.
- 1
Dry-roasted peanuts
The Professor Nutz base, roasted for that deep, old-fashioned peanut butter flavor.
- 2
Corn fiber
The natural fiber at the heart of Digestibility Corrected. It binds to fat in the gut, so more of it passes through undigested.
- 3
Sweetener
Soluble tapioca fiber, thaumatin and stevia. A touch of sweetness with 0g added sugars.
- 4
Glycerol monostearate
An emulsifier that keeps it smooth between stirs.
- 5
Salt
A pinch, for real peanut butter flavor.
How the fiber does its job.
Get your scientific brain on for a moment.
Fiber binds to fat
Professor Nutz is the first peanut butter with added natural fiber. In the gut it binds to fat, so more of that fat passes through undigested.
Digested is what counts
The calories your body digests are different from the total calories you eat. Digestibility Corrected is an FDA term for correcting a label to the calories a food actually yields.
Corrected on the label
Old School Smooth lands at 36 calories† and 0g digested fat per two tablespoons, with 7g of protein. How much you digest can vary from person to person.

Copycats copy labels. They can't copy a study.
Plenty of jars talk about low calories now. Ask to see their own published, peer-reviewed study. Ours is right up there.
Every flavor. Every ingredient.
