In the food
Cyclodextrin is blended into every WiO product. It sits alongside the dietary fat and carbohydrates in the food as you eat it normally.
A fiber that binds the fat. Eighteen years in real food.
A modified cyclodextrin binds dietary fat and carbs before they are digested. Independent, double‑blind study.
From the WiO kitchen
Cyclodextrin is a naturally derived soluble fiber with a hollow, ring-shaped structure. The opening captures dietary fat and carbohydrate molecules. Because the body cannot break apart cyclodextrin, the bound contents pass through intact rather than being absorbed.
Cyclodextrin is blended into every WiO product. It sits alongside the dietary fat and carbohydrates in the food as you eat it normally.
Inside the digestive tract, the ring-shaped fiber captures fat and carb molecules. They fit inside the cavity the way a key fits a lock. The binding happens before absorption can occur.
The fiber and its captured contents move through the digestive tract unabsorbed. They exit the body, so their calories and carbs bound to the fiber are not available for storage.
Nutrition Facts. Digestive Facts. Both on every product. WiO may be the first food brand to print both panels. The FDA published guidance in 1993 on labeling foods with non-absorbed components. We follow it. One panel shows what goes in. The other shows what your body absorbs.
Example: WiO Tortilla Chips, 56g serving. Digestive Facts values are estimates based on in-vitro binding studies. Individual results will vary based on diet and digestive factors.
An independent, double-blind crossover study at the Applied Science and Performance Institute in Tampa, FL tested one 12-oz jar of peanut butter daily for 14 days. Same total calories in both arms. The groups differed only in the fiber.
DXA measurement. Same calories in both arms. Difference was statistically significant (p = 0.05, 95% CI 0.11 to 1.88 kg). Sample size is small (n = 6); crossover design compensates because each subject was their own control.
From the kitchen: the science figured it out. I just put it in your food.

Love the taste, or we make it right. Thirty days. If WiO isn't food you actually want to eat, tell us and we'll sort it out.
The cyclodextrin fiber from the study is in every WiO product. Start anywhere.
Modified cyclodextrin is recognized as Generally Recognized as Safe (GRAS) by the U.S. Food and Drug Administration for food use.
The European Food Safety Authority (EFSA) has reviewed and approved cyclodextrin for use as a food ingredient in the EU.
Health Canada has approved cyclodextrin for use in food products sold in Canada. The same ingredient, the same approval record.
Modified cyclodextrin has been used in pharmaceutical drug delivery for over 40 years. The safety profile is well established across that use.
All studies listed are publicly available in peer-reviewed journals. WiO does not control or sponsor the research. We use the science.
Six key studies shown. See the full reference list on the peanut butter study page, or contact us for the complete bibliography.
