Men’s X-Action Reloaded combines nutrients to support male reproductive function, sexual performance and enjoyment, prostate health and cardiovascular health. Ingredients in the formula work together to support optimal nitric oxide levels in the body. Nitric oxide relaxes blood vessels to enable optimal blood flow. Efficient blood flow is crucial for healthy male sexual activity and overall vascular health. Icariin, a flavonoid extracted from epimedium, may selectively inhibit phosphodiesterase type V (PDE-5), an enzyme that causes the male sexual response to subside. By blocking this enzyme, sustained activity may be promoted. Icariin also plays a role in increased smooth muscle relaxation and increased blood flow through its actions on cyclic guanosine monophosphate (cGMP) levels and nitric oxide synthase (NOs) activity.
