What is Progesterone & Who Needs It?
100 more published studies for progesterone cited on this page
Progesterone is the Master Hormone in all women. It is the hormone responsible for balancing the activities of a woman’s 27 different estrogens. It is the hormone used by the body to make many other necessary hormones, including estrogen, allopregenalone & testosterone. Optimal progesterone levels, is foundational for a woman to enjoy good health & wellness.
- If a cycling woman fails to maintain sufficient progesterone during “that time of the month” she will experience some of the 150 symptoms of PMS/PMT, including cramping, irritability, headaches, etc…
- A premature drop in Progesterone levels during pregnancy will almost always result in a miscarriage, or pre-term birth. A normal, sharp drop in progesterone levels on or about week 40, will trigger the birth of the baby & almost always result in “post-partum depression”.
- Progesterone stimulates bone building cells called osteoblasts to build new bone tissue more effectively than any other influence, including aerobic exercise. Bone loss in women, begins, on average at age 37, resulting in 1.5% bone mineral density loss per year.
- Men need progesterone to make testosterone
- Progesterone supports prostate health
- Progesterone supports production of serotonin & has been labeled the “Happy Hormone”

A Tale of Two Progesterones
The journal Postgraduate Medicine, 2009 Jan;121(1):73-85, stated, in part:
“Physiological data and clinical outcomes demonstrate that bioidentical hormones are associated with lower risks, including the risk of breast cancer and cardiovascular disease, and are more efficacious than their synthetic and animal-derived counterparts.
Until evidence is found to the contrary, bioidentical hormones remain the preferred method of HRT.
Of special concern is their relative safety compared with traditional synthetic and animal-derived versions, such as conjugated equine estrogens (CEE), medroxyprogesterone acetate (MPA), and other synthetic progestins. Bioidentical hormones have some distinctly different, potentially opposite, physiological effects compared with their synthetic counterparts, which have different chemical structures.
Both physiological and clinical data have indicated that progesterone is associated with a diminished risk for breast cancer, compared with the increased risk associated with synthetic progestins.” link [mfn]The bioidentical hormone debate: are bioidentical hormones (estradiol, estriol, and progesterone) safer or more efficacious than commonly used synthetic versions in hormone replacement therapy?[/mfn]

- Progesterone is the precursor for Allopregnanalone (the nervous system has the capacity to bio-convert progesterone into its active metabolite allopregnanolone. The enzymes required for progesterone and allopregnanolone synthesis are widely distributed in brain and spinal cord. Increased local biosynthesis of pregnenolone, progesterone and 5α-dihydroprogesterone may be a part of an endogenous neuroprotective mechanism in response to nervous system injuries. Progesterone and allopregnanolone neuroprotective effects have been widely recognized) link10

Clarification of a Long-Standing Misconception
It is important to note, there are two progesterones, one made by the body and one that is molecularly altered and patentable.
It is a common practice for health care professionals to say “progesterone” when referring to the synthetic “progestin”.
This is an important distinction, as “progestins” have a litany of side-effects. Conversely, “biologically identical progesterone” has a 40+ year history of safe, effective use, when administered in a safe cream formula.
