Raspberry ketones are a natural compound responsible for the aroma of red raspberries. Research has shown its potent fat-burning capabilities stem from its ability to stimulate the production of the hormone adiponectin. Adiponectin naturally tricks the body into acting like it is thin, thus encouraging the fat cells in your body to give up their fat: Higher adiponectin = lower levels of body fat. However, it does so without stimulating the cardiovascular system, in stark contrast to other thermogenic (metabolism increasing) supplements. In addition, higher levels of adiponectin have been shown to control the metabolic derangements that may result in type 2 diabetes, obesity, atherosclerosis, non-alcoholic fatty liver disease and metabolic syndrome. You would have to ingest 90 pounds of raspberries to get the benefit of just 100 mg of raspberry ketones. Each serving of SL Series Raspberry Ketone contains 200 mg of raspberry ketones.
