Effect of a Multi-Nutrient Over-the-Counter Supplement on Changes in Metabolic Rate and Markers of Lipolysis.

What Was Tested

This clinical study looks at Copper (Supplement).

Using a prospective, randomized, double-blind, crossover study design, fifteen healthy male (n = 8) and female (n = 7) participants (mean ± standard deviation (SD): 28.3 ± 6.1 yr, 176.3 ± 11.4 cm, 89.8 ± 21.7 kg, 28.5 ± 4.8 kg/m2) completed this study.

Two testing sessions occurred after an overnight fast and refraining from physical exercise.

Who Took Part

By PubMed's age tags, the people studied were young adults and adults, both men and women.

How the Study Was Run

The design is described as randomized, double-blind, placebo-controlled and crossover.

The participants were allocated by chance, so the Copper (Supplement) group and the comparison group should start out alike.

Neither the participants nor the staff measuring them knew who was on Copper (Supplement), so expectations could not easily colour the readings.

A placebo (an inactive look-alike) gave the Copper (Supplement) group a baseline to be compared against.

Each person switched between Copper (Supplement) and the comparison at some point, usually with a gap in between.

What Was Measured

Two testing sessions occurred after an overnight fast and refraining from physical exercise.
