What this trial studies

This clinical trial aims to evaluate the effects of nitrate supplementation on erectile function in men aged 40 to 65 with low nitric oxide (NO) levels. Twenty participants will be recruited from Ballantyne Medical Associates in Charlotte, NC, and will undergo screening and informed consent processes. Participants will be randomly assigned to receive either a placebo or Berkeley Life nitrate capsules, and their erectile function will be assessed using the International Index of Erectile Function (IIEF) questionnaire and other measures at baseline, during crossover, and at the conclusion of the study.

Who should consider this trial

Good fit: Ideal candidates are men aged 40 to 65 who have been undergoing treatment for erectile dysfunction for at least 90 days with unsatisfactory results and have low nitric oxide levels.

Not a fit: Patients with a history of drug or alcohol dependency, those with known allergies to the capsule ingredients, or those currently taking organic nitrates for acute angina may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could provide a new treatment option for men experiencing erectile dysfunction due to low nitric oxide levels.

How similar studies have performed: While the approach of using nitrate supplementation for erectile dysfunction is not widely tested, similar studies have shown promising results in improving erectile function through nitric oxide modulation.
