I started with 3 pills 3x's a day. But, the key is to make sure you are taking enough. If you don't smell, take more. I am on my 4th nursing experience (6th baby, 2 set of twins). I've taken it in the past and it was NO help at all. This time, I decided to take a lot more after reading what others do. I ended up at 6 pills 3x's per day before I finally started smelling like maple syrup and noticed an increase in my supply. No adverse affects for baby at all.
