Yes, I have pcos. Niacin was the missing ingredient for me. Spiro gave me a VERY loud smell that was similar to a mix of chemicals and must. It was a musty/musky smell that I can't really put my finger on. It almost smelled like peanut butter, a very musty, hot/wet peanut smell.
It was strange and I never smelled anything like it on anybody before. My smell filled the room too. If you are on spiro, I would look into alternative options. I regret taking it.
PLEASE add niacin and use the forms of zinc, magnesium, and niacin that I used and in the amounts. Please take the zinc in the morning and the magnesium at night. The niacin is to be take by itself 3 times a day. The niacin is referred to as flush niacin and that is exactly what it did for me. It seemed to flush the circulating hormones out of my body and the smell from coming from my body. It has not returned.
