What is Cayenne Pepper Extract?

What are the Health Benefits of Cayenne Pepper Extract?
As mentioned, cayenne pepper extract contains capsaicin which acts as a pain reliever by reducing the amount of a neuropeptide known as substance P that is produced by the body. Substance P travels through the bloodstream to the brain to signal pain, thus the less substance P that is produced, the less pain you will feel. Cayenne pepper extract also has other health benefits including the potential to reduce blood pressure, boost your metabolism, and reduce hunger.  The National Center for Biotechnology Information (NCBI) conducted studies which determined that the long-term consumption of capsaicin can reduce blood pressure levels. The NCBI also determined that capsaicin can increase the heat which your body produces, in turn helping your body burn more calories and boost your metabolism. The NCBI also found that cayenne pepper extract reduces the levels of ghrelin within your bloodstream, a hormone that is responsible for the feeling of hunger.
