Detailed Description
This study is a pilot, open-label study to evaluate the efficacy, safety and tolerability of a Prostate Health formulation. Each subject will receive a specific dose of the formulation once daily.
Participants will undergo assessments of blood tests, vital signs, body weight, BMI with completion of questionnaires.
The primary objective of the study is to assess effectiveness of the Prostate Health formulation on the I-PSS score.
Secondary objectives:
- To assess the I-PSS "Quality of Life" question score
- To assess the PSA level
- To assess the IIEF-5 questionnaire score
- To assess body weight
- To assess BMI
- To assess the score on a questionnaire for health-related quality of life
