The effects of a thermogenic supplement on metabolic and hemodynamic variables and subjective mood states.

What Was Tested

This randomized controlled trial looks at Copper (Supplement).

To determine whether a thermogenic supplement affects metabolic rate, hemodynamic responses, and mood states.

Who Took Part

PubMed tags the participants as women only.

Thereafter, subjects ingested the assigned treatment (active treatment containing caffeine, micronutrients, and phytochemicals [TR] or placebo [PL]).

Subjects repeated the same protocol with ingestion of the opposite treatment on a separate day.

How the Study Was Run

The researchers set it up as a randomized, double-blind, placebo-controlled and crossover study.

Because people in this Copper (Supplement) study were split into groups at random, differences between the groups are less likely to reflect who happened to join each one.

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

Some participants received a placebo instead of Copper (Supplement), giving a reference point.

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

All variables were reassessed at 30-, 60-, 120-, and 180 min post-ingestion.

What Was Measured
