phenylethylaminePhenylethylamine, also known as PEA, is a stimulatory transmitter, which means that it helps release neurotransmitters in your brain like dopamine and norepinephrine. These reduce hunger and also improve your digestive health.
caffeineCaffeine is a bitter, white crystalline xanthine alkaloid that acts as a stimulant drug. It stimulates our central nervous system thus giving us more energy. Our body becomes more active and burns calories faster.
theobromineTheobromine is a bitter alkaloid of the cacao plant. It is found in chocolate, as well as in a number of other foods, including the leaves of the tea plant, and the kola (or cola) nut. Because of this diuretic effect, and its ability to dilate blood vessels, theobromine has been used to treat high blood pressure.
carallumaCaralluma is a type of Cactus that grows in India. Traditionally, Indian tribes chewed chunks of caralluma to keep from being hungry during a long hunt. Phen Caps contains extracts of Caralluma to decrease appetite for weight loss. It is also used to quench thirst and to increase endurance.
synephrineSynephrine is found in many species of plants, however the main source today is citrus aurantium, also known as “bitter orange”. This compound helps burn calories and improve insuline sensitivity, which means that it reduces the risk for diabetes and metabolic syndrome.
l-carnitineL-Carnitine is an amino acid, responsible for the transportation of fatty acids to the mitochondria – the cell parts that produce energy for your body. It supplies the heart with additional energy, increases your stamina, and helps the muscles to recuperate faster after an intense workout or running session.
raspberry ketoneRaspberry ketone is the primary aroma compound of red raspberries. This compound regulates adiponectin, a protein used by the body to regulate metabolism. Raspberry ketone causes the fat within your cells to get broken up more effectively, helping your body burn fat faster.
crateagusThis is a hawthorn berry extract, which is widely recognized as a cardiovascular tonic. Hawthorn berries are used in traditional medicine in the treatment of chronic heart failure, high blood pressure, irregular heartbeat, and digestive problems.
seleniumSelenium is a trace element found in many foods including Brazil nuts, seafood, and enriched grains. It is critical to various biological processes in humans. Adequate selenium is necessary to support thyroid function and prevent related weight gain.
