Brief Summary:

An expanding number of studies suggest a therapeutic role for nitrate and nitrite, most notably in treatment and prevention of cardiovascular disease including ischemia-reperfusion injury and hypertension. The nutritional aspects of these cardioprotective effects are particularly intriguing since nitrate is abundant in our everyday diet. Nitrate improves vascular functions in old adults and improves ischemia reperfusion injury in experimental models.

Whether dietary nitrate improves erectile dysfunction is not known and will be investigated in the present study.

Primary Outcome Measures :
  1. The changes of erectile function according to the international index of erectile function (IIEF5) score [ Time Frame: 4 Weeks ]
    Erectile dysfunction improvement as measured by IIEF5 score (range 5-25)

Secondary Outcome Measures :
  1. Change in oral microbiome [ Time Frame: 4 Weeks ]
    Change in oral microbiome after dietary nitrate ingestion

  2. Change in cardiac diastolic function, [ Time Frame: 4 weeks ]
    Change in cardiac diastolic function as determined by echocardiography via measurement of E/A and E/e' aggregated to display diastolic function
