Hormones – Progesterone
Progesterone is the female hormone produced by the ovaries and adrenal glands. It functions to balance the effects of estrogen. Progesterone may be viewed as a lifelong partner of estrogen, in a balanced relationship of yin and yang.
Progesterone stimulates bone growth while estrogen halts bone loss.* Natural progesterone enhances the action of estrogen as these two hormones were meant to work together to maintain a normal hormonal balance.
Female hormone levels of estrogen and progesterone drop dramatically after menopause. It comes as no surprise that after menopause heart disease in women skyrockets, surpassing even the male population. In fact, it is the leading cause of death in older women with over a half-million deaths per year in the United States, more than twice as many as all cancer deaths combined.*
The combination of natural progesterone and estrogen can prevent this downward spiral by keeping women vital, strong and healthy.*
Possible Side Effects:
There are no side effects associated with natural progesterone. However, if there is estrogen dominance, women may experience premenstrual mood swings, depression, breast swelling, craving for sweets, heavy or irregular periods, sleep disturbances, weight gain, acne and or water retention.
Natural progesterone comes in many forms, most commonly topical creams, the oral capsule and the sublingual tablet. The recommended form is sublingual. Progesterone levels should be measured by a physician to ensure that the levels are within therapeutic range.
Frequently Asked Questions:
Is progesterone taken continuously or is it better to cycle?
Estrogen and Progesterone can be administered either way. Discuss options with your physician.
Can I take estrogen only?
Progesterone counter balances the negative effects of estrogen. It is recommended that both be taken together.
I have had a hysterectomy and my doctor says progesterone is therefore no longer needed, is that true?
No, it is not. Progesterone has many benefits outside of the uterus and is necessary to counter balance the effects of estrogen replacement.
On its own, natural progesterone replacement has a mild tranquilizing effect and enhances an overall sense of well-being.*
The ovaries begin producing progesterone in earnest around puberty, and the monthly ebb and flow of this hormone, in harmony with estrogen and other hormones continues until menopause. Progesterone’s primary role during this period is to help make the uterus ready for implantation of a new embryo, the first major event – after fertilization of the egg – in the 9 months of human gestation. If the egg is not fertilized, progesterone production temporarily ceases, and the uterus sheds its endometrial lining.
Testosterone deficiency has also been linked to hypertension, obesity, increased risk of heart disease and depression. Stress levels may also play a role in declining testosterone levels.*
“The main reason women discontinue HRT is due to side effects. Synthetic progestin’s (Provera®) cause may side effects: breast swelling and tenderness, uterine bleeding, depression and mood disturbance, weight gain, bloating and edema. Natural progesterone has no side effects.” Female Patient 2001 Oct; 19-23.
