Progesterone, a crucial hormone in the female reproductive system, plays a vital role in regulating the menstrual cycle, pregnancy, and overall hormonal balance. Many women, especially those experiencing hormonal imbalances or menopausal symptoms, turn to progesterone supplementation. But, a common question arises: Should progesterone be cycled, or should it be taken continuously?
Understanding Progesterone’s Role
Progesterone works in harmony with estrogen to maintain hormonal balance. During the menstrual cycle, progesterone levels rise after ovulation to prepare the uterine lining for potential pregnancy. If pregnancy doesn’t occur, progesterone levels decline, leading to menstruation. Progesterone also falls as ovulation becomes more irregular in perimenopause. This leads to symptoms like anxiety, insomnia, heavy periods, weight gain, and mood swings.
We also now know that progesterone is made the first 2 weeks of the cycle by enzymes throughout the body, especially in the adrenal gland.
The Case for Cycling Progesterone
Some experts advocate for cycling progesterone to mimic the natural fluctuations of the hormone cycle. This approach involves taking progesterone for a specific period (generally, days 14-26 of the cycle) followed by a hormone-free interval until the next luteal phase.

The Case for Continuous Progesterone
Other experts recommend continuous progesterone use, particularly for women experiencing menopausal symptoms like hot flashes, night sweats, or insomnia.

The Bottom Line
Cycling vs. not cycling progesterone is a topic of hot debate. Ultimately, the decision on how to dose this hormone depends on the individual woman. I took progesterone continuously when I was perimenopausal because I needed it for sleep. And sleeping only 2 weeks out of the month was unacceptable to me!
Science and our understanding of hormones continue to evolve. If your prescriber says there’s only one way to do it, look for a more informed healthcare provider.
