Xenadrine Rfa-1 is a leading thermogenic weight loss supplement that promotes fat burning. Thermogenics are a type of weight loss aid that increase the metabolism by generating heat, causing the body to burn more calories than at its Basal Metabolic Rate (BRI). Many patients note increased energy while taking thermogenics, and have achieved successful results when combining Xenadrine Rfa-1with a healthy diet and regular amounts of exercise. Xenadrine Rfa-1 is known as an ECA stack, containing ephedra, caffeine and aspirin. In addition, it supplements these active ingredients with Bitter Orange.
Ephedra
Ephedra is a plant native to Asia that is commonly used to treat bronchial conditions, such as asthma. A stimulant and a thermogenic, ephedra increases the body's metabolism by raising the heart rate, increasing blood pressure and providing neurological stimulation. When using ephedra, patients often feel more energetic and less fatigued during exercise.
Caffeine
Caffeine is a stimulant that can be found in several common beverages, including coffee, soda and tea. Caffeine stimulates the central nervous system, delaying the onset of fatigue and promoting alertness. In addition, it promotes a rise in free fatty-acid levels, providing an alternative source of fuel for the body instead of stored glycogen. Xenadrine Rfa-1 has caffeine in the form of guarana seed extract, a plant native to the Amazon rainforest.
Aspirin
Xenadrine Rfa-1 contains aspirin in the form of Willow Bark Extract, a natural source of salicin. Aspirin is often combined with ephedra and caffeine in weight loss supplements because it increases the base metabolic rate of the body, causing the body to use more calories for energy and burn more body fat.
Bitter Orange
Xenadrine Rfa-1 is considered a "double stack" because it is an ECA stack, as well as contains Bitter Orange, also known as Synephrine. Bitter Orange is in the form of Citrus aurantium in Xenadrine Rfa-1 and contains similar molecular properties as ephedra. Bitter Orange is also a thermogenic, promoting fat loss and raising the body's metabolism.
