Maca extract, one of the ingredients of Forza, is an herb that is native to the high Andes mountain range in Peru. Its common traditional use is for promoting strength, libido, and endurance. The part of the herb used is the root. Another ingredient blended within Forza is L-Arginine, which is an important amino acid. It is a component of protein, required by the body to permit it to heal from injuries, and facilitate normal hormone production to allow the blood vessels to open properly. L-Arginine is used to produce a chemical in the body called “nitric oxide” (NO), which makes the blood vessels open wider, allowing blood to flow through the body.
