Oral micronized progesterone is the "natural" type of progesterone that can be taken in a pill form. This form of progesterone is beneficial for hormone replacement therapy (HRT) as it closely mimics the progesterone naturally produced in the body. It has been associated with fewer side effects compared to synthetic progestins, and it may provide additional benefits such as improved sleep, reduced hot flashes, and potential protection against certain estrogen-related risks, making it a preferred option for some individuals seeking hormone balance and menopausal symptom relief.
