Protein hydrolysate for appetite control

Protein hydrolysate for appetite control

DNF-10® is a hydrolysate fraction from Saccharomyces cerevisiae which acts on the gut-brain mediators of satiety, to lower calorie intake and reduce body fat mass. Benefits demonstrated after the first weeks. Supported with 4 published clinical trials. 500 mg/day.

DNF-10® - Key features

  • Patented ingredient

  • Demonstrated mechanism of action: gut-brain axis moderation of the appetite

  • Significant reduction of calorie intake after first weeks of supplementation

  • Significant weight loss after the first month

  • The weight lost is from fat mass

  • Abdominal fat and waist circumference decrease significantly

Science supporting DNF-10®

More than 10 years of research have been conducted to support the mechanism of action and clinical benefits of DNF-10® on body composition. The mechanism of action of DNF-10® on the mediator of satiety has been studied in vivo in animal models. The reduction of food intake and improvement of body composition have been confirmed with interventional human clinical trials.

More than 10 articles supporting the mechanism of action and health benefits of DNF-10® have been published.

Process & characterisation

DNF-10® is an active fraction produced by the protein hydrolysis of Saccharomyces cerevisiae, a yeast species used for thousands of years in baking, fermented food and beverage manufacturing processes. 

The manufacturing of DNF-10® involves enzymatic proteolysis and the use of ultrafiltration to select peptides with a molecular weight <10 kDa. The material is then spray-dried to obtain a dried powder. 

Active compounds:
  Patented yeast protein hydrolysate from Saccharomyces cerevisiae
  Strain NBRC (ex. IFO) 2346
  Peptide size: <10 kDa

Composition: Saccharomyces cerevisiae extract.

Recommended daily dosage: from 500 mg

Mechanism of action

DNF-10® acts on the gut-brain axis by regulating the mediators of appetite

Mechanistic studies highlighted that DNF-10® plays a role in regulating serum levels of the appetite hormone ghrelin.

DNF-10® helps to maintain the release of the satiety hormone, leptin, from the adipocyte.

The action of  DNF-10® on these 2 hormones leads to a reduction in the secretion of the neuropeptide and appetite neuromediator Y (NPY).


Mechanistic studies
Animal model

  • DNF-10® significantly lowers ghrelin secretion.
  • DNF-10® significantly lowers the expression of NPY in the hypothalamus.
  • The effect of DNF-10® on decreasing food intake is rapid.

Satiety enhancer

  • Subjects taking DNF-10® supplements decrease their caloric intake significantly after the first weeks of supplementation.
  • After 2 months, the daily caloric intake drops by 600 kcal.
  • All 3 groups of macronutrients are significantly impacted: subjects reduce the number of calories from lipids, proteins, and carbohydrates.
  • After a few weeks of consuming DNF-10®, subjects have a reduced appetite for sweet foods. 

Body weight loss

Weight loss is significant after one month of supplementation with DNF-10®. Moreover, 100% of the weight lost is from fat mass, leading to a 6% reduction in the fat mass ratio.

Abdominal fat reduction

The change in  body composition is confirmed by computed tomography. The subjects’ total abdominal fat mass is significantly reduced by 5% with DNF-10®. Waist circumference is reduced by 5 cm after supplementation. 

DNF-10® is safe

No adverse event linked to DNF-10® supplementation has been recorded.
