The most common reason for PMS is due to inadequate production of progesterone. Progesterone is manufactured in the ovaries, adrenal glands and during pregnancy. For women, progesterone is important for the regulation of ovulation and menstruation. High levels of stress, such as from a poor diet, low carb/low calorie diet, excessive exercise, lack of sleep and anxiety, your progesterone levels can decrease and your hormone levels can become even more imbalanced. 

Maintaining healthy progesterone levels means more than just a healthy menstrual cycle and healthy fertility. An unbalanced ratio of progesterone and estrogen levels are responsible for PMS symptoms such as mood swings, acne, bloat, breast tenderness, and more.
