I've never used that product. Years ago i did have an overgrowth of candida in the stomach after a lot of antibiotics.
What helped me was going on a strict diet. My doctor told me to not eat any yeast, wheat, caffeine, alcohol, dairy, sugars, honey, jams and no extremely sweet fruits or fruits which ferment easily eg: melons and grapes. Potato, rice, eggs,vegetables and gluten free foods were fine as well as non dairy milk, but you could use soy, rice or almond milk. I also had to take a course of multivitamins as yeast depletes your nutrients. I also had to take an probiotic twice per day.
After only 2 weeks i felt like superwoman, when prior to that i had chronic fatigue, could sleep for 12 hours, had no motivation or interest in life and had developed very bad irritable bowel and had lost weight which i couldn't afford to lose.
You can easily do this type of diet and take the probiotics (best taken on empty stomach half and hour or one hour before meals), i'm sure it would be much cheaper than buying products which claim to kill off yeast. You can easily kill off yeast by stop consuming what yeast thrives off. I've never had the problem since and that was close to 11 years ago.
