Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

A randomized, double-blind, placebo controlled, parallel study to determine if Chromium (Cr), Phyllanthus emblica (PE) and Shilajit (SJ) supplementation and Phyllanthus emblica fruit extract supplementation promotes greater changes in glucose homeostasis, endothelial function, and cardiometabolic risk in sedentary and overweight men and women initiating an exercise and weight loss program.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Men and women with at least 2 markers of metabolic syndrome will participate in a randomized, placebo-controlled, parallel, and repeated measures intervention trial. Volunteers will participate in a standardized resistance training (3 sessions/week) and aerobic training (3 x 30 min sessions/week) program while reducing energy intake by 5 kcals/kg/d.

In a double-blind and randomized manner, participants will be matched by age, sex, BMI, and body mass to supplement their diet with placebo (PLA), 400 mcg of trivalent chromium with 6 mg of PE and 6 mg of SJ (Cr-400), or 800 mcg of trivalent chromium with 12 mg of PE and 12 mg of SJ (Cr-800), or 500 mg of PE (PE-500), or 1000 mg of PE (PE-1000) once a day after breakfast for 12-weeks.

Fasting blood samples, DEXA body composition, platelet aggregation, and ultrasound flow-mediated dilation (FMD) studies will be conducted at 0, 6, and 12 weeks of supplementation.
