For more information about bio-identical hormones generally, click here.
Progesterone is the most popular and well-known bio-identical hormone. Natural progesterone is exactly identical to the progesterone made by your own body. This is very different than the "progesterone" in the Pill and conventional HRT, which are progestin drugs. Progestin drugs have many side effects, and are fundamentally a completely different thing than natural progesterone.
Natural progesterone can be used effectively to treat many hormonal problems including PMT, painful breasts, infertility, osteoporosis, and peri-menopause.
Natural progesterone for hot flushes
In a new study from the University of British Columbia in Vancouver, "natural" progesterone was shown to be effective for hot flushes.According to lead author Dr Prior, "This is the first evidence that oral micronized progesterone, which is molecularly identical to the natural hormone, is effective for women with symptomatic hot flashes."
"Women improve very quickly on oral micronized progesterone," she said. No serious side effects were noted. Progesterone may be suitable for women that cannot take oestrogen. (1)
Natural progesterone for oestrogen-dominance
Oestrogen dominance is the ratio of too much oestrogen compared to progesterone. It is caused by estrogen-mimicking pollutants in our environment, use of the birth control pill, over-production of stress hormones, and poor liver detoxification of oestrogens.
Symptoms include heavy periods, fluid retention before the period, breast tenderness, fibroids and weight gain on the hips.
Natural progesterone is also effective for:
- Endometriosis
- PCOS
- Breast cancer prevention
- Migraine headaches
- Anxiety and depression
Is it safe?
Why are French women so lucky? Their doctors have no problem because prescribing Natural Progesterone.
Natural progesterone has been used in France and other parts of Europe for many decades. It has a well-established safety record, and that is starting to become more apparent in the research.
The "E3N cohort study" is a French health study that is following over 100,000 menopausal women over many years. It has provided some interesting information about HRT and the benefit of natural progesterone (micronized progesterone) vs conventional progestin. First of all, the E3N study found that unlike progestin, natural progesterone does not increase the risk for breast cancer. (2) Now, the latest information from the E3N study is that micronized progesterone is far safer than progestins when it comes to cardiovascular disease. Unlike progestins, which are a stroke risk, micronized progesterone may actually reduce the risk for stroke. (3)
Bottom Line about Natural progesterone
In recent years, standard oestrogen prescriptions have changed from horrid horse urine oestrogens to a bio-identical oestradiol in a patch or gel. Essentially these modern oestrogen prescriptions are natural or "bio-identical". They are much safer and more effective than the horse urine of 8 years ago.
The same shift is going to happen with progesterone. At the moment, progestin drugs are the standard prescription in Australia and North America. However, study after study is emerging to show that bioidentical progesterone is safer and more effective than progestin. It is only a matter of time until the official recommendations catch up. "Natural" progesterone will to become the norm.
But what happens in the meantime? Must women accept the progestins that cause breast cancer, stroke, depression and bone loss?
At the moment, if a women wans progesterone, she must obtain it through an alternative route, and thenrisk chastisement by her doctor. Pretty silly considering that the very same doctor may be routinely prescribing the exact same hormone in 5 years time.
Medicine can be fickle sometimes.
How much should be used?
As Naturopaths, we recommend a low-dose approach to natural hormones. We recommend that you use the minimal dose necessary for relief of symptoms. Founders of progesterone therapy like Dr John Lee used only 10-20 mg of progesterone per day. This is about what the ovaries would make under normal circumstances. Some Australian doctors have been prescribing up to 10 times this amount. As a patient, if you are using more than 1/2 gram of a 3% cream, or more than 0.5 of a 70mg troche, you need to reconsider the appropriateness of that.
