The take a look at, which turned into posted in the journal Obesity, became a scientific overview of 315 randomized controlled trials-taken into consideration the gold fashionable in medical studies-that evaluated how properly 14 dietary supplements labored. Of those, the handiest 16 of the randomized controlled trials determined evidence of massive weight adjustments (from 1-10 lbs.) in people who took supplements vs. A placebo in the course of the take a look at duration.
