Guaraná for Weight Control

Why Use

Guaraná

Why Do Dieters Use It?*

Some dieters say that guaraná helps improve weight loss results.

What Do the Advocates Say?*

The herb guaraná contains caffeine and the closely related alkaloids theobromine and theophylline; these compounds may curb appetite and increase weight loss. Caffeine’s effects are well known and include central nervous system stimulation, increased metabolic rate, and a mild diuretic effect.1 In a double-blind trial, 200 mg per day of caffeine was, however, no more effective than a placebo in promoting weight loss.2 Because of concerns about potential adverse effects, many doctors do not advocate using caffeine or caffeine-like substances to reduce weight.

*Dieters and weight-management advocates may claim benefits for this supplement based on their personal or professional experience. These are individual opinions and testimonials that may or may not be supported by controlled clinical studies or published scientific articles.
