Slendesta® Natural, Healthy Appetite Management Ingredient

Sticking to a healthy diet and managing your weight isn’t easy. You've learned the hard way that weight loss won't happen overnight. In order to achieve long-term success, it's important to control your hunger and avoid binge eating. Slendesta is a dietary ingredient for satiety that offers the support dieters need to control hunger and feel full between meals.

When formulated into a supplement or food product, Slendesta helps:

  • Boost satiety to help you feel full sooner and longer.1
  • Suppress your appetite and control hunger, which makes dieting easier and helps with weight management.1
  • Promote weight loss and reduce waist and hip measurements when used with a sensible diet and exercise routine.2,3

A Safe And Natural Weight Management Solution

Slendesta is a safe, natural potato protein-based dietary supplement ingredient that boosts satiety to help you feel full without any unpleasant side effects.4 The satiety ingredient has been clinically shown to help individuals eat less and feel satisfied sooner and longer.1 The ingredient’s satiety benefits make it easier to control portion size and snacking, and in turn, achieve weight management goals.

Natural, Healthy Appetitive Management Ingredient Developed With Advanced Plant Science

The active molecule in Slendesta is a well-studied protein called Proteinase Inhibitor II (PI2). PI2 works by promoting and extending the body’s natural release of cholecystokinin (CCK), a powerful peptide that signals key organs, including the stomach and brain, to induce feelings of fullness. To leverage the powerful satiety benefits of PI2, our plant scientists began searching for a natural source of this molecule.

We discovered that russet potatoes have naturally occurring higher levels of PI2 and can serve as a botanical factory for our satiety ingredient.5 The Kemin Specialty Crop Improvement (SCI) team used traditional plant breeding methods to further develop these potatoes.

A safe dietary ingredient for satiety

Slendesta is generally recognized as safe (GRAS) and has been shown to be well tolerated in all human clinical trials with no adverse side effects related to the study product.1-7
