Micronized Progesterone (Prometrium)
Micronized progesterone is gentle and effective. It’s often better tolerated than synthetic progestins and may offer bonus sleep support. Some women experience grogginess or mood changes, but for many, it’s a smooth ride.
Micronized progesterone is a bioidentical hormone used to balance estrogen therapy and reduce the risk of endometrial cancer.
This form of progesterone is molecularly identical to what your body makes and is often preferred for its lower risk profile. It’s taken orally at bedtime and has a sedating effect for many women.
Avoid if allergic to peanuts (Prometrium brand), or if you have a history of progesterone-sensitive cancers or clotting issues
Drowsiness, grogginess, mood changes, spotting
