Termogénicos

What are Thermogenics?

A thermogenic supplement is a dietary product aimed at increasing resting metabolic rate and promoting fat loss. Due to its intended action, this type of supplement is also known as “fat burner”. Some thermogenic supplements provide other ingredients commonly used to support appetite control and diuretic activity.

Thermogenics often contain a combination of ingredients popularly used in weight loss plans, including natural extracts with long histories of use in traditional medicines around the world. The most popular ingredients are by far caffeine and green tea extract, but there are others commonly found in these formulas, such as L-carnitine, capsaicin, conjugated linoleic acid, and green coffee, guarana, garcinia cambogia, and bitter orange extracts.

Studies have evaluated the potential benefits of thermogenic supplements’ common ingredients in terms of:

  • Increasing resting energy expenditure
  • Promoting fat oxidation
