What Causes Milky Penile Discharge After Taking Green Coffee Bean Extract?

I recently started lift weight and working-out. I'm 51 years of age. I started taking a liver cleanse and green coffee bean extract. My concern is my penis leaks a milky with fluid and there is NOT any burning sensation during urination. Could this be a result of the supplements I'm taking or should I go and get checked out. There has be occurring for about a week now.
