Undecylenic acid is an organic fatty acid derived from castor bean oil that supports a healthy balance of yeast in the gut. Pathogenic and opportunistic yeasts, like Candida albicans, spread quickly through the intestines by creating tiny roots, or hyphae, that can become deeply embedded in the intestinal wall. This embedment of hyphae makes it very difficult to control yeast overgrowth in the body. MegaMycoBalance can help support a healthy yeast balance in the gut by targeting these roots. A study published in the Journal of the American Medical Association found a direct correlation between vaginal yeast infections and simultaneous overgrowth of Candida in the digestive tract. As a result, MegaMycoBalance can support a healthy balance of vaginal flora by restoring balance to the intestinal flora. Bee propolis is a plant resin with natural antifungal properties that bees use to line their hives.
