  Purpose
Obesity is a major health issue worldwide; there is a constant raise in obesity related death each year. In vitro and animal studies elucidated Actiponin as a novel anti-obesity agent. However, the efficacy and safety of Actiponin supplementation on body weight regulation in humans are lacking.

Condition Intervention Phase
Obesity Dietary Supplement: Actiponin Dietary Supplement: Placebo Phase 2

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Double (Participant, Investigator)
Primary Purpose: Prevention
Official Title: Actiponin Supplementation Reduces Abdominal Fat Area, Weight, Body Fat Mass and BMI in Obese Korean Subjects.

Arms Assigned Interventions
Experimental: Actiponin
Actiponin(extract of Gynostema pentaphyllum, 450mg/day) for 12weeks
Dietary Supplement: Actiponin
The dried leaves of G. pentaphyllum leaves were extracted with 50% ethanol and filtered; the filtrate was concentrated under high pressure and high temperature. Damulin An and B, analytical marker of Actiponin, exist more 2.49% and 1.06% respectively in raw material.
Other Name: Extract of Gynostemma pentaphyllum(450mg/day)
Placebo Comparator: Placebo
Placebo(450mg/day) for 12weeks
Dietary Supplement: Placebo
Amount and calorie of placebo are same with Actiponin.
Other Name: Placebo(450mg/day)

Detailed Description:

The primary aim of the study was to investigate the effect of Actiponin in Korean subjects on body weight and fat loss along with changes in metabolic markers based on 12 week, randomized, double-blind, placebo-controlled clinical trial.

Eighty obesity subjects with BMI > 25kg/m2 and waist-hip ratio (WHR) ≥ 0.90 for men and ≥ 0.85 for women were randomly divided into either Actiponin (n=40, 450mg/day) or placebo group (n=40, 450mg/day) for 12weeks.
