Vitamins and Nutritional Supplements

Dr. Kathryn Retzler has developed a line of private-labeled supplements to make sure you receive unsurpassed, quality formulas that are affordable and effective. All supplements that bear a HormoneSynergy® label are manufactured in facilities that have pharmaceutical or NSF certification and are certified for good manufacturing practices (cGMP). It's important to keep in mind that not all products are alike, no matter what the label or packaging may claim.  All HormoneSynergy® formulas are manufactured by companies that perform product analysis to verify safety, potency, and bioavailability. Several HormoneSynergy® supplements have undergone clinical trials to ensure efficacy, and all HormoneSynergy® supplements are used by Dr. Retzler in her private practice.*
