Progesterone is a key hormone in women’s health, often called the “calming hormone” for its role in supporting restful sleep, mood stability, and a sense of balance. It helps regulate the menstrual cycle, supports fertility, and counters the stimulating effects of estrogen. When progesterone levels drop—especially during perimenopause and menopause—women may experience anxiety, insomnia, irregular cycles, or heavy bleeding. Supporting healthy progesterone levels can bring relief, restore emotional well-being, and help you feel more in control of your body and mind.
