Dr. Kathryn Retzler and HormoneSynergy® teamed up with the top four nutraceutical and supplement manufacturers in the United States to develop a line of private-labeled and custom nutraceuticals 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). One of our manufacturers has recently earned the prestigious Therapeutic Goods Administration (TGA) certification, the Australian equivalent to the U.S. Federal Drug Administration.

All HormoneSynergy® formulas are manufactured by companies that only sell to licensed healthcare providers and all perform product analysis to verify safety, potency, and bio-availability to ensure quality and constituency.
