The #1 cause of candida is not really a mystery. Youíll find it listed in the 62,000+ studies on PubMed, the National Institutes Library of Medicine. Youíll find it in every hospital and medical office. Itís antibiotics! Itís not sugar, hormone replacement therapy, diabetes, stress, mercury, or sex. Sure, each one of those can help support the growth of candida, but they donít cause it. Antibiotics are the #1 cause of candida.
