A common ingredient of diet patches is focus vesiculosus, a brown algae. This organism is a rich source of iodine, and is used to stimulate the thyroid gland to increase metabolism, reports the Diet Channel. Guarana and L-carnitine are also ingredients found in diet patches which supposedly work by increasing the body's metabolism. DHEA, 5-HTP and yerba mate patches are used by dieters in patches for their appetite suppressing effects. Other ingredients, such as flaxseed oil, lecithin and zinc pyruvate are used as general supplements to maintain a balanced body weight, according to the Diet Channel.
Many of these ingredients have been proven to assist in weight loss, but the method of application in these studies is commonly orally, reports the Diet Channel. Proponents of diet patches state that the method of applying the drug does not matter, while skeptics believe skin patches do not allow the ingredients to enter the body rapidly enough to significantly affect the user's metabolism or appetite. Because of this, diet patches remain a controversial treatment until scientific studies further examine their efficacy.Learn more about Medications & Vitamins
