Clinically effective

A randomized, double-blind, placebo-controlled trial in 54 women showed that Relizen significantly reduced hot flashes compared to placebo, with greater reductions over time ¹


After 3 months, 65% of patients taking Relizen experienced a reduction in their daily hot flashes ¹

Non-hormonal

Relizen relieves vasomotor symptoms with no hormonal effect* 1-3


 In an in vitro study

  • Relizen produced no proliferation of MCF-7 breast cancer cells, which are dependent on interaction with estrogen receptors, in contrast to 17-beta estradiol, which produced proliferation ³

 In a pre-clinical study

  • Relizen did not increase uterine weight even at 100x the equivalent human daily dose. In contrast, ethinyl estradiol increased uterine weight ²

 In a clinical study

  • Relizen showed no impact on measurements of estrogen, testosterone, FSH, and SHBG and showed no difference in breakthrough bleeding versus placebo¹
