Physician's Preference offers a wide variety of yeast supplements to support our bodies' healthy, normal bacteria for proper digestion, metabolism, immune system function and many other major biological actions. However, this balance can be disrupted by the use of antibiotics, birth control pills, synthetic steroids, estrogen replacements and high carbohydrate diets. Find products such as Sweet-n-Natural, coconut oil, Yeast Cleanse, and Probiotic Blend that may be helpful in killing the yeast and restore the healthy bacteria.
