Black Ginger Extract

Clinically proven for improved blood flow for improvement of cold hand and feet, muscle endurance, and men' sexual health*

Black Ginger is loaded with flavonoids particularly with high content of polymethoxtflavone among all the flavonoids. In collaboration with Kyoto Pharmaceutical University, 8 variance of polymethoxyflavone were identified in Black Ginger Extract with the highest content of 5,7-dimethoxyflavone present.  Findings from human clinical trials show that standardized Black Ginger Extract improves peripheral blood circulation and peripheral vasculature, such as can be found in Raynaud's syndrome. Peripheral blood circulation improved 57% within an hour after taking 150 mg of our Black Ginger Extract.*  

Improved blood circulation also has positive effects on AMP-activated protein kinase (AMPK) which may improve physical fitness performance, muscular endurance, and fat metabolism.*

Additionally Black Ginger Extract has demonstrated inhibitory effect on PDE5 (phosphodiesterase-5), similar action found in Viagra.*
