Good question, I couldn't really tell you - because I tend to give a combo of calcium undecyclenate, caprylic acid, garlic (allicin standardized), clove, GSE, berberine, etc.
I tend to use a shotgun rather than a rifle these days.
I found poor results years ago when using single products way back in teh eary days when I first started treating yeast infected patients, and get better results with a combo approach. Watch this space.
