Study summary

The purpose of the study is to evaluate the effect on weight loss in a group of subjects suffering from overweight and mild obesity (BMI between 25 and 32 Kg/m2) and with weight > 75 Kg/m2 being administered with a 3 g/day polyglucosamine dosage.

Read the detailed description

The primary objective of the study is to evaluate the effect on weight loss in a group of subjects suffering from overweight and mild obesity (BMI between 25 and 32 Kg/m2) and with weight > 75 Kg/m2 being administered with a 3 g/day polyglucosamine dosage.

The secondary objectives of the study are:

  • to evaluate the effect of supplementation on blood triglyceride levels
  • to evaluate the effect of supplementation on blood levels of Total Cholesterol (CT), LDL, and HDL
  • to evaluate the effect of supplementation on glucose, insulin, insulin resistance assessed by calculating the Homeostatic metabolic assessment (HOMA)
  • to evaluate the effect of supplementation on liver enzymes (transaminases) and renal function (creatinine)
  • to evaluate the effect of supplementation on BMI (Body Mass Index)
  • to evaluate the effect of supplementation on the abdominal circumference
  • to evaluate the effect of supplementation on body composition evaluated by dual X-ray densitometer (DXA)
  • to evaluate the effect of supplementation on the serum levels of reactive oxygen species
  • to evaluate the effect of supplementation on serum antioxidant capacity
