The participants took 1 of 5 interventions:

500 mg of Amla
1,000 mg of Amla
6 mg of Amla, 400 µg of chromium, and 6 mg of shilajit
12 mg of Amla, 800 µg of chromium, and 12 mg of shilajit
A placebo.

The participants performed 3 sessions per week of aerobic exercise with resistance training and walked 10,000 steps per day 3 other days of the week.

There were 11 primary outcomes, consisting of blood lipids, glycemic control, and vascular (blood vessel) function outcomes.

Amla at 500 mg worsened fasting glucose compared to the placebo. Flow-mediated dilation improved with 500 mg of Amla and with the combination of 12 mg of Amla, 800 µg of chromium, and 12 mg of shilajit compared to the placebo.

The company that produces the supplement funded the study.
