The Safety of Bioidentical Hormones
Bioidentical Hormones are safer and more effective than synthetic hormones. (1-2)
Do You Have Hormone Excess or Hormone Deficiency ?
A deficiency or an excess
of women's bio-identical hormones can produce adverse symptoms.
This is called estrogen deficiency/excess, and progesterone
deficiency/excess, and they each have typical signs and symptoms easily
Common Signs of Estrogen Deficiency (4)
Difficulty Falling Asleep
Common Signs of Excess Estrogen:
enlargement, tenderness or pain
Common Signs of Progesterone Deficiency
periods at all (no ovulation)

No Adverse Events from Bio-Identical
Hormones Reported to the FDA: NONE
Over-the-counter pain pills (NSAIDs) such as aspirin, naproxen™ and ibuprofen™ are considered fairly safe. After all, you don't need a prescription to buy them, yet they cause an estimated 16,500 deaths in the US annually, mostly from gastric bleeding.(5) Compare this to no reported adverse events from bio-identical hormones in 2008, according to an FDA press conference January 2008.(6) Bioidentical hormones must be considered safer when compared to commonly available over the counter pain remedies. However, one must remember that hormonal excess or deficiency is associated with the adverse events and the symptoms listed above.
FDA Admits No Adverse Reports: Transcript of FDA Press Conference Jan 9, 2008:
Kathy Anderson (of the FDA): With your
respect to your question about whether we received any adverse event reports,
we have not.
from: Transcript of FDA Press Conference on FDA Actions on Bio-Identical
Hormones. Moderator: Susan Cruzan, January 9, 2008 Edited for brevity.(6)
Hormones Cause Breast Cancer? (7)
The 2002 WHI (Women’s Health Initiative) study revealed that synthetic hormones increase the risk of breast cancer. However, Bioidentical Hormones do not. How do we know this? The French Cohort Study showed there was no increased risk of breast cancer in women using bio-identical hormones.(8)(43) Rather, the 2008 French Cohort Study by Fournier showed that in women using hormone replacement combination drugs, increased breast cancer was associated with synthetic progestin use, while women using bioidentical progesterone had no increased breast cancer (compared to non-hormone users).(43) Remember, in addition to avoiding synthetic hormones, the addition of Iodine supplementation is our most useful tool for prevention of breast cancer. See the chapter on breast cancer prevention with iodine supplementation for more on this.(10)
Do Bio-Identical Hormones Cause Heart Disease ?
Again, we know from the 2002 WHI study that synthetic hormones cause heart disease, and bioidentical hormones do not. Calcium score is an accepted measure of heart disease risk. A study of CAT calcium scores by JoAnn E. Manson in the June 2007 JAMA actually lower scores, and less heart disease in the women taking estrogen (they had hysterectomies and were not given the synthetic progestins).(11) These same results had already been published 2 years previously in a calcium score study by Budoff in J Women’s Health 2005. (12) Clearly the data shows that bioidentical hormones are protective and prevent heart disease, while synthetic hormones increase heart disease risk.
What Was the Women's Health Initiative - WHI Study
The WHI study was the large NIH sponsored medical study in which synthetic hormones were given to women. The WHI study consisted of two arms. The first arm used the combined synthetic hormones Premarin™ and Provera™, and the second arm used Premarin™ alone. The WHI results were published in JAMA in 2002 and 2004.(13-14)
What is Premarin and Provera?
Premarin™ and Provera™ are not bio-identical hormones. Premarin™ is a hormone obtained from pregnant horses, which contains Equilin, a horse hormone not found in humans.(15) Provera™ is a synthetic hormone which is not found anywhere in the natural world . (16) The Premarin™ and Provera combination is called PremPro™, a synthetic hormone pill commonly prescribed by mainstream medicine. Prempro™ was the hormone preparation used in the first arm of the WHI study.(13) Prempro™ is currently in litigation in drug court. Women are seeking damages from the PremPro™ manufacturer claiming Prempro™ caused their breast cancer.
WHI study First Arm:
The WHI study (first arm published in JAMA 2002) was terminated early because the combination of premarin™ and provera™ (Prempro™) caused increased breast cancer and heart disease.(13) Immediately after this WHI study was published in JAMA in 2002, there was a massive switch by women to bio-identical hormones which resulted in a 4 billion dollar loss for Wyeth, the maker of Prempro™.
WHI Study (Second Arm):
All the women in the second arm of the WHI study had prior hysterectomies (uterus absent), so they did not need the synthetic progestin, called Provera, which is required to prevent the endometrial cancer caused by Premarin alone. Rather, this post-hysterectomy group was given Premarin alone (the horse hormone, also called CEE, for Conjugated Equine Estrogen). Unlike the first arm of the study, these women had no increased risk of breast cancer. (18) Premarin causes endometrial cancer, so the mainstream medical system always gives Provera (progestins) to prevent endometrial cancer, unless of course, the uterus is absent from prior hysterectomy.(20)(56)(57)
The WHI Culprit was the Synthetic Progestin (an altered form of Progesterone)
Back to the first arm of the WHI which used Prempro, it is clear from the data that the culprit which caused breast cancer and heart disease was Provera™, a synthetic monster hormone. This is nothing new. For years, Provera™ has been known to cause heart disease and breast cancer.(21-22)(39) Three previous large scale human studies revealed increased breast cancer with progestin use. The Breast Cancer Detection Demonstration Project published in JAMA in 2000 showed an eight fold increase in breast cancer for estrogen-progestin users compared to estrogen alone users. (53) The Swedish Record Review published in 1996 had a four fold increase in breast cancer with progestin use. (54) The Million Woman study published in Lancet in 2003 had a fourfold increase in breast cancer for estrogen-progestin combination users compared to estrogen alone users.(55) A 2007 animal study with primates treated with either bioidentical progesterone or a progestin (Provera™) showed that the progestin drug (Provera™) worsens breast cancer biomarkers, while the bioidentical progesterone provides a beneficial effect on breast tissue and reduces cancer markers.(22)
Monster Hormones are Chemically Altered
Chemically altered hormones were used in the WHI study, and are routinely handed out by the medical system. These altered hormones are monsters that should never have been approved for marketing to the American people. They should be banned.
The Media Says Hormones Cause Cancer and Heart Disease
If bio-identical hormones are so safe, then why do the newspapers say that women's hormones cause breast cancer and heart disease?(23) The answer is that the media and the medical profession routinely confuse synthetic chemically altered monster hormones with the bio-identical hormones. The drug companies intentionally create this confusion because they want to hide the fact that synthetic hormones are monsters that should be banned.
Chemically altered hormones were made because of a quirk in our legal system which grants patent protection for chemically altered versions of a natural substance. The natural hormones were chemically altered so that they could be patented to protect profits from competition. Naturally occurring bio-identical hormones by law cannot be patented. Examples of monster synthetic hormones are provera, all progestins, and birth control pills which are never found in nature. These are the monster hormones.
A Listing of a Few Monster Hormones: Chemically Altered
Chemically Altered Progesterone: Dienogest, Desogestrel, Drospirenone, Dydrogesterone, Ethisterone, Etonogestrel, Ethynodiol diacetate, Gestodene, Gestonorone, Levonorgestrel, Lynestrenol, Medroxyprogesterone, Megestrol, Norelgestromin, Norethisterone, Norethynodrel, Norgestimate, Norgestrel, Norgestrienone, Tibolone
Chemically Altered Estrogen: Dienestrol, Diethylstilbestrol, Ethinylestradiol, Fosfestrol, Mestranol
Chemically Altered Hormones in Birth Control Pills: levonorgestrel and ethinyl estradiol [oral contraceptive] (Alesse 28, Aviane, Nordette, Seasonale, Triphasil, Trivora-28); norethindrone and ethinyl estradiol (Combi Patch, Loestrin FE 1/20, Neocon 1/35, Ortho-Novum 7/7/7, Ovcon 35); norgestimate and ethinyl estradiol (Ortho-Cyclen, Orthotri-Cyclen, Trinessa); norgestrel and ethinyl estradiol (LO/OVRAL 28, Low-Ogestrel), desogestrel and ethinyl estradiol (Desogen, Miracette, Ortho-Cept), drospirenone and ethinyl estradiol (Yasmin)
Chemically Altered Testosterone: Androstanolone, Fluoxymesterone, Mesterolone, Methyltestosterone
An Illustration Explaining the Problem of
Supposing a biochemist working for a drug company has an idea to alter the chemical structure of vitamin C so a patent can be obtained. The biochemist adds a chlorine molecule to the vitamin C carbon ring, and gives is a new name "super-Vitamin C", which is really a chlorinated version of vitamin C. Next they do a one year medical study with 5,000 people taking the chlorinated vitamin C tablet every day, and another 5000 people taking a placebo. After the year is up, they count a 0.5 per cent incidence of heart disease events in the Super Vitamin C group and a 1.0 percent in the placebo group. FDA approval is easily obtained based on reduction in heart disease events by 50 per cent (0.5 per cent is 50% of 1.0 %). The drug company is at liberty to spend million dollars on television advertising designed to rake in millions more for the new heart prevention miracle drug. This absurd scenario is now the norm for our medical system. Why would anyone want to spend money for a monster version of vitamin C when the real thing is available for pennies? Why use a monster hormone when human hormones are available? Compared to their monster counterparts, Bio-Identical Hormones are more effective, have fewer adverse side effects, and are less costly.
High Hormone Levels of Early Pregnancy Confer Protection from Breast Cancer.
During the 16th century in Italy, breast cancer was quite rare. An Italian doctor, Bernardino Ramazzini, noted in 1713 the relatively high incidence of breast cancer in nuns and wondered whether this was related to celibate lifestyle.(24) Recent studies confirm that early pregnancy and multiple pregnancies confer protection from breast cancer, while no pregnancies (as in the nuns) leads to increased risk of breast cancer.(25) This protection is thought to be conferred by high levels of progesterone. This was confirmed in a 2007 study by Rajkumar showing hormone treatment protected genetically engineered mice from developing breast cancer. (26)
Progesterone, the Great Protector
Progesterone is so safe, it is available over the counter without a prescription. In addition, a deficiency of progesterone is associated with an increase in breast cancer risk.(27) Progesterone is known to be protective and prevents breast cancer.(28)
Why Don't Birth Control Pills use Natural Progesterone?
Birth Control Pills, BCP's, are very effective at preventing pregnancy by suppressing ovulation. However, BCP's contain synthetic hormones which have adverse side effects.(29-31) To avoid these monster hormones, the IUD (intra-uterine device) is available. Make sure you ask the doctor for a plain IUD, without the implanted hormones. In the future, BCP’s will be made from natural progesterone which is available in highly absorbable micronized oral capsules.
Warning About IUD’s With Synthetic Hormones
Avoid synthetic hormones in IUDs. If you plan on using an IUD, ask for a PLAIN IUD without synthetic hormones implanted in it. (IUD=Intra-uterine device)
