The Push Catch Liver Detox

The Push Catch Liver Detox

A mainstay of my work has always been the Liver, Gallbladder & Ileo Cecal Valve. The main organs of detoxification. I decided to go back to my roots and reintroduce The PushCatch® LiverDetox- a versatile two-step cleansing protocol designed to help support the liver. It is widely accepted that eliminating toxins and then minimizing their redistribution and reabsorption is essential for proper health. Other improperly designed protocols on the market can result in unwanted redistribution, not elimination.*

This elegant and powerful formulation and delivery chemistry derive from Dr. Christopher Shade’s extensive research into detoxification pathways. In the “push” phase, powerful antioxidants assist a liposomal blend of bitters that support bile flow and help mobilize substances out of the tissues. Flowing into the gut, natural binders “catch” the compounds so that they can be safely eliminated by the body. Our PushCatch® contains a broad-spectrum constellation of binders that are blended with uniquely soothing prebiotic fibers.*

The PushCatch® Liver Detox integrates two unique Quicksilver Scientific products:

Dr. Shade’s Liver Sauce®: Certain botanicals have a potent effect on bitter receptors and phytonutrients can support healthy inflammatory response to support the different phases of liver detoxification and toxin elimination.* Dr. Shade’s Liver Sauce® contains a blend of four classic drainage botanicals and a synergistic medley of powerful phytonutrients.*

UltraBinder®: In the body, binders work across the gut to intercept and neutralize an array of toxins. UltraBinder™ contains a comprehensive, broad-spectrum binder, and because binders can be constipating, we added a soothing and fluidizing acacia gum and aloe vera to the blend.*

This system is highly flexible and can be used as a gentle, daily standalone detox, or as an intensive program.

Effective cleansing respects the fact that our body has built-in, highly evolved defense mechanisms that include adaptation, habituation, and a tendency to tilt toward homeostasis. Botanicals and phytonutrients that promote detoxification, drainage and elimination can be highly effective, but over time, the body may habituate to stimulation and become less responsive.

Cycling between on and off periods, and titrating doses from low to high over time are both key concepts essential for effective, safe detoxification. Cycling will give the body a necessary rest, and allow it to reset during the off period, so that detoxification can be resumed with full effect.

Titrating dosages and schedules up over time offers a scalable, flexible, and tolerated approach that is suitable for all, from the highly sensitive to the highly robust and resilient.

The PushCatch® LiverDetox can be adapted for very light frequent detoxification and can also be slowly scaled up for more intensive, deeper cleanses.

Suggested use:

1. Take a dose of Dr. Shade’s Liver Sauce, (remember to hold in mouth 30-60 seconds before swallowing.)

2. 30 minutes later take a dose of UltraBinder, then3. Wait 30 minutes before eating

Let’s do once a day before breakfast.  If that absolutely will not work then we will still do once a day between 1-4pm

Disclaimer: This system is not intended to diagnose or treat any disease. The dosing schedule below is designed to serve as a guide, and should not supplant guidance concerning the use of these supplements provided by your healthcare practitioner.

Caution: Because Ultra Binder™ contains activated charcoal and other substances which may affect the absorption of medications, it should be taken at least two hours before or after prescription medications.5 days on 2 days off!!    This is the Beginners program on the attached PDF

The Truth about Watermelons…and Benefits

By: Catherine Ebeling 

Nothing says “Summer” better than a cool, refreshing, sweet, juicy, delicious slice of ripe watermelon—no matter what time of year it is. But I often hear cautions on eating watermelon—that it is high glycemic, full of sugar, mostly water, not very nutritious, etc.

NOTE: While watermelon does contain fruit sugar —fructose — like all other fruits, it is nearly 92 percent water. Just because it tastes sweet does not make it high in sugar. … This term, called glycemic load, is very low for watermelon — meaning that blood sugar is not changing much after eating it-but for diabetics, don’t overdo it!

Right? Or wrong?

While watermelons are mostly water—90% or so, they are also full of vitamins A, B6, C, lycopene, antioxidants and minerals. Remember hearing about the lycopene in tomatoes? Watermelon, another red-colored fruit, is FULL of this powerful phytonutrient! In fact, watermelon has some of the highest levels of lycopene of all fruits and veggies. Just one cup of watermelon has 1 and a half times the lycopene of a large fresh tomato. And who eats just one cup of watermelon? I know I don’t!

Because watermelon is one of the best sources of lycopene with more than 6,500 micrograms in less than half a cup, you are getting an army’s worth of inflammation-fighting antioxidant activity! Lycopene from the red flesh of watermelon is very stable, even after the watermelon has been cut and stored in the refrigerator. Lycopene is thought to be even more powerful than its other orange/red colored ally, beta carotene—found in red and orange fruits and veggies.

Cardiovascular Benefits

Lycopene is a powerful natural anti-inflammatory and antioxidant, valued for its role in protecting the cardiovascular system, bone health, and preventing cancer. Along with lycopene, watermelons contain another powerful phytochemical, citrulline, an amino acid. Citrulline gets converted into another important chemical in the body, arginine, or L-arginine. Arginine is used to create nitric oxide, which has powerful benefits on the heart and blood vessels. NO can actually cause blood vessels to relax and open up, lowering blood pressure and helping the body carry more oxygen to parts of the body where it is needed–like muscles, your heart and your brain. A study from Florida State University found that watermelon could make a significant difference in lowering blood pressure–especially in overweight people, by relaxing the blood vessel walls.

Citrulline, when it converts into arginine, can also help prevent excess accumulation of fat in fat cells, because it blocks an enzyme that stores this fat. And because citrulline is a precursor to nitric oxide, it can also help improve erectile dysfunction in men, in a similar way that Viagra works—although you would have to quite a bit of watermelon to get the same effect as Viagra.

As you can see in this article, watermelons are on the list of foods that beat statins for heart health!

It’s All About the Lycopene

Carotenoids are powerful antioxidants, capable of destroying free radicals which attack our bodies and can contribute to chronic disease and aging. In one study of 13,000 adult Americans, low levels of carotenoids were a key predictor of early death. Especially low blood levels of lycopene! Lycopene protects our cardiovascular system, the male reproductive system, and in the skin, it protects and prevents UV damage from the sun.

Several studies have been conducted showing the strong link between levels of lycopene and heart disease. Analyses from the Physicians Health Study showed a 39% decrease in stroke risk in men with the highest blood levels of lycopene. Another study in Finland following 1,000 men for 12 years has had similar results as well.

Lycopene is also responsible for limiting the enzyme responsible for making cholesterol, so eating foods with more lycopene also helps to reduce cholesterol—specifically, LDL cholesterol.

Anti-Cancer Power

Lycopene is a life-saver in more ways than one! Besides its cardiovascular benefits, lycopene’s antioxidant power extends to anti-cancer effects as well. A 2014 meta-analysis of 10 studies shows dietary lycopene to be protective against ovarian cancers, as well as brain tumors and breast tumors.

And of course, we know about lycopene’s value in fighting prostate cancer. In several studies, higher intakes of foods containing lycopene and a higher serum or plasma concentration of lycopene was associated with a very significant decreased risk of prostate cancer—especially the more lethal kind of prostate cancer. When researchers studied only the men who had had at least one high risk PSA test, the subjects had a 50% decreased risk of lethal prostate cancer.

“Based on these results, we hypothesize that the consumption of a diet rich in lycopene-containing foods reduces the aggressive potential of prostate cancer by inhibiting the neoangiogenesis that occurs in tumor development,” Dr. Giovannucci’s team reported online ahead of print in the Journal of the National Cancer Institute.”

Other studies have shown lycopene’s powerful cancer fighting ability effective against lung cancer, esophageal, stomach, pancreatic, colorectal, and cervical cancers as well.

Extremely Good for Rehydration

Watermelons get their name because they are over 90% water, and that water is full of electrolytes and potassium which helps you stay hydrated or to rehydrate. The perfect fruit to eat on hot summer days, or after a hard, sweaty workout! And that delicious juice can also help prevent muscle soreness—especially if you have watermelon before your intense workout.

It’s Not Just the Red Part

While most of us only eat the juicy red flesh of the watermelon, the whole thing is actually edible and chock full of nutrients! From the red center to the stem end, and also the blossom end–including the white part near the rind–are a plethora of impressive antioxidants, flavonoids, lycopene, and vitamin C. Even the green rind is full of nutrients. The rind is full of chlorophyll, and contains even more citrulline than the red flesh. Try throwing your watermelon rinds into the blender with fresh squeezed lime juice for a healthy slushy treat.

It is still best, however, to pick ripest, reddest watermelon you can find. Lycopene content continues to increase all the way up until the time the watermelon is at its reddest and ripest.

And don’t spit out those seeds, unless you are in a watermelon seed-spitting contest! The black watermelon seeds are not only edible, but actually extremely good for you. They are full of iron, zinc, fiber and protein. Seedless watermelons are ok to eat too—they are not genetically modified, only hybrid forms of watermelon bred especially for their no-seed content.

Watermelons also are rich in anti-inflammatory substances including cucurbitacin E, triterpenoid which help to block the pain and inflammation of certain enzymes, in a similar fashion as NSAID’s like ibuprofen and aspirin.

While being very low in calories (only about 46 calories in a cup), watermelon also contains an impressive variety of other important essential nutrients including:

  • Vitamin A
  • Vitamin C
  • Vitamin B6
  • Potassium
  • Magnesium

The Age-Old Question—How Do You Pick the Perfect Watermelon?

It can be a huge gamble finding the perfect, red, sweet watermelon. But—if you know what to look for, there is a real method to finding the best one. Look on the underside of the watermelon for a pale, butter-colored yellow spot—not white or green. This is one of the best indicators of the ripeness of the watermelon. Also pick up a few and choose the one that is heaviest for its size. Many people ‘thump’ the watermelon to check its ripeness too—listen for the best hollow bass sound.

Be aware that watermelons do contain a reasonable quantity of fructose, so be mindful of your sugar intake, and eat watermelon in moderation.  With that said, because watermelons are so filling, and have both high water content AND high fiber content, the old myth that watermelons are high glycemic is not entirely true… This is because the “glycemic load” of a watermelon is actually fairly low since it’s nearly impossible to overeat large quantities of a food that is as filling as watermelon

The Secret of Healing is the Power of Belief

The Secret of Healing is  the Power of Belief

Proof is in Bible Quotes—Positive Affirmations of Faith

“All things are possible to him that believeth.”   (Mark 9:23)

“Be not faithless, but believing”   (John 20:27)

“And these signs shall accompany them that believe; in My name shall they cast out demons; they shall lay hands on the sick and they shall recover.”   (Mark 16:17, 18)

I believe; help Thou, my unbelief”   Mark (9:24)

Positive Affirmation:

“Yes, Source and Maker, I believe You can and will heal any person upon whom I lay my hands”

Negative Affirmation:

Sick folks have faith and plenty of it—but in the wrong way.  Your attention is your faith.  Whatever gets your attention, you have faith in.  Whatever you expect and prepare for, you have faith in.

Some facts about Faith:

Words of faith can be creating, or dissolving, according to whatever one has faith in.

The power of faith has equal authority to destroy one’s health, if used destructively as do words of faith that create a and build up one’s health

A person who is sick and attending a healing circle to receive healing prayers will get not better if he keeps talking about his ill health and listens to descriptions of ill health problems enjoyed” by a neurotic neighbor. Through that person’s faith and attention to ill health, he keeps it manifesting.  His faith is indeed an irrepressible force, but for illness instead of wholeness.

Gratitude Intervention

Simple 3-Step Gratitude Practice


Gratitude is more than a positive personality trait or a willy-nilly feeling. Gratitude has the power to change the lens through which we view the world, bringing us more joy, health and satisfaction. It’s easy to see the problems in life, not because we are cynical, but because we are looking for what we can improve in our lives. The downside to this is that we can skip over the miracles in our lives, taking the small gifts for granted. 

Creating a gratitude practice such as a gratitude jar, gratitude meditation or a gratitude journal is a great way to press pause on that dissatisfied inner voice constantly seeking more. 

The Definition of Gratitude

The word gratitude is derived from the Latin word gratia, which translates as grace or favor. Interestingly, the word grace is defined as “smoothness and elegance of movement” and “courteous goodwill,” which speaks of bringing flow and harmony into your life. 

Another phrase for gratia in Latin is “gratus animus.” Gratus means grateful, agreeable, pleasing, acceptable and welcome. Animus means heart, mind, affections, purpose and feeling. Much of human life is about kindness and compassion (giving and receiving), which makes a gratitude practice so transformative. 

Recognizing and affirming benevolence has a vitalizing effect on the mind, body and spirit. That might be why gratitude is at the core of every major spiritual tradition. The roots of a gratitude practice must be in selflessly rejoicing in the other and seeking opportunities for giving, rather than using it as a narcissistic self-improvement technique. 

A practice of gratitude will help you to live a wonderful life, and is the opposite of being entitled. Rather, a practice of gratitude is rejoicing in the gifts and wonders of life. Gratitude has been established as a universal human attribute suggesting that it is at the core of our very being. 

The Healing Power of Gratitude

Gratitude has amazing powers of improving mental health and has proven in clinical trials to have long lasting healing properties. It promotes feelings of love and tenderness toward other people and life experiences. A deep practice of gratitude also has the power of alleviating trauma, due to its other-directed understanding. 

Gratitude is used in a clinical setting with Accelerated Experiential Dynamic Therapy (ADEPT). ADEPT was designed by American psychologist Diana Fosha. The premise is that we are all capable of self-healing and transformation in the right environment. ADEPT is designed to create a deep emotional connection with both yourself and other people. 

“Be content with what you have; rejoice in the way things are. When you realize there is nothing lacking, the whole world belongs to you.”  —Lao Tzu

In the paper Gratitude as a Psychotherapeutic Intervention published by Yale Center for Emotional Intelligence and the University of California, the writers astutely wrote: “Losing some aspects of one’s life may lead the person to increase the value they see in other aspects of life.” 

Gratitude Breeds Connection

We all know that it’s nice to get gifts, but the feeling of joy from material objects is fleeting. Taking the time to be truly thankful for all of the blessings in your life will open doors. Our life depends on the existence of everything in the universe, from the sun and moon to the oceans and trees. And each person can play a special role in our lives. Taking the time to write a thank you note to spread the love has also been shown to benefit those with mental health challenges. 

“With this attitude, people recognize that they are connected to each other in a mysterious and miraculous way that is not fully determined by physical forces, but is part of a wider, or transcendent context.”  -Streng (1989) 

Gratitude can be seen as the elemental life force that powers compassion. We are all intricately connected and as such a practice of gratitude gives thanks to the interdependence, interpenetration, and mutuality of living. 

Gratitude isn’t merely positive thinking; it is a deep appreciation for life. Contrast can also be viewed through the eyes of gratitude. Pain and affliction can be released when they are contrasted with more positive aspects of the now. No matter how small, there is always something to be grateful for. 

What does a Gratitude Practice Look Like?

In the first instance you can simply pay attention to what is going well in your life. Taking time to shift your focus from the negative to the positive. A gratitude practice should include the understanding that even painful situations are teachers. The simple act of redirecting our focus can take us from a place of victimhood to appreciation, altering our view of the world. 

Simple 3-Step Gratitude Practice

  • Step 1 – Attention – become aware of the blessings in your life that you may have taken for granted. 
  • Step 2 – Tune into the many reasons for gratitude that exist in our lives. 
  • Step 3 – Write it down – Writing is scientifically proven to be more powerful than simply thinking thoughts of gratitude. You can choose to write down one thought a day and place it in a gratitude jar. Or you may like to keep a special gratitude journal and write down 5-10 blessings every day. 

If you choose to use a gratitude jar, you can amplify the benefits by sharing the experience with your family. Sharing a gratitude jar will encourage family members to have a grateful outlook on life. Counteracting feelings of entitlement, envy, and resentment, which are negative feelings that push people away from us. A  gratitude jar encourages each member of the family to practice thinking in a positive way that will bring joy, prosperity and connection into your home. 

“Always be rejoicing. Give thanks for everything.”  -1 Thessalonians 5:16, 18.

In Conclusion

Gratitude intervention remains an untapped therapeutic resource that can be used by anyone, especially those working in healthcare settings. Changing the perspective of a patient from one of despair to gratitude could catalyze their healing process. Adding gratitude techniques is an easy way to boost your self esteem and that of those around you. 

ZRT Topical Progesterone

Topical Progesterone, Not Synthetic Progestins or Oral Progesterone, Should Be Considered as a Companion for Estradiol Replacement Therapy

Dr. David Zava Friday, January 17, 2020

Topical Progesterone, Not Synthetic Progestins or Oral Progesterone, Should Be Considered as a Companion for Estradiol Replacement Therapy

In 2002 several large-scale clinical studies were published on the risks of breast cancer in postmenopausal women using conventional FDA-approved hormone therapy. These were the Women’s Health Initiative (WHI) and Million Women’s studies of women using FDA-approved estrogens and progestogens in the United States and Great Britain, respectively [1,2]. Both studies came to the same conclusion – that estrogen therapy, mostly in the form of oral conjugated equine estrogens, by itself did not significantly increase the risk of breast cancer and, to the surprise of many, was associated with a lower risk. However, when estrogen was combined with a synthetic progestin to prevent uterine cancer, the breast cancer risk increased 1.5 to 2-fold. Virtually all forms, of which there are many, of synthetic progestins increased risk to about the same extent. Smaller studies suggested that FDA-approved oral progesterone, which was not as widely used, did not increase risk in combination with estrogen therapy. These results led to widescale panic among postmenopausal women using conventional estrogen and progestogen (both synthetic progestins and natural progesterone) therapies and a precipitous drop in prescriptions for these forms of HRT [1]. Many women stopped cold turkey all forms of hormone replacement therapy (HRT), which significantly diminished their quality of life. Adverse estrogen deficiency symptoms that were effectively suppressed with estrogen therapy (e.g., hot flashes and night sweats, sleep disturbances, memory issues, incontinence, vaginal dryness, depression, weight gain, etc.) resurfaced with a vengeance in many women, as did risk for diseases of advanced aging (e.g., bone loss and osteoporosis, cardiovascular disease, stroke, diabetes, senile dementia, Alzheimer’s disease). Women were left frightened between “damned if you do and damned if you don’t,” and a large majority chose not to continue HRT. Many health care providers refused to prescribe hormone therapy until more information about risks were made available through clinical trials.

Natural Progesterone Reduces Breast Cancer Risk

It was clear to me from the research literature and smaller clinical studies that the natural hormone progesterone, when delivered topically at a physiological dose (25 mg) protects normal breast tissue from the growth promoting actions of estrogens.

When these and other studies emerged in 2002 John Lee, MD, and I along with Virginia Hopkins had just published our book entitled, “What Your Doctor May Not Tell You About Breast Cancer: How Hormone Balance Can Help Save Your Life” [3]. The short of the book is that if your hormones are out of balance and you are suffering from symptoms and conditions of advancing age, meaning the transition into menopause and beyond, then you should replenish your hormones back to physiological levels with the same hormones that your body made when you were healthy early middle age. This meant if you were to use estrogen replacement therapy (ERT) you would replace with estradiol and/or estriol, not a synthetic estrogen like ethinyl estradiol (synthetic estrogen found in birth control pills) or a conjugated horse estrogen (Premarin). And if you were taking a progestogen to help balance the estrogen and protect against its proliferative effects, use bioidentical progesterone, not a synthetic progestin like medroxyprogesterone acetate (Provera) or other synthetic “fake” progesterone. We already knew from earlier studies published several years before WHI that the synthetic progestins were increasing the incidence of breast cancer [3, Chapter 11]. As a research scientist at that time, who had spent 20+ years researching and publishing on the role of estrogen and progestogen binding to their receptors and regulating breast cell proliferation and differentiation, it was clear to me from the research literature and smaller clinical studies that the natural hormone progesterone, when delivered topically at a physiological dose (25 mg) protects normal breast tissue from the growth promoting actions of estrogens [4]. In the breast cancer book [3] we delved into a lot more of what the scientific literature says causes breast cancer and what can be done to help prevent it, like avoid bad foods and environmental chemicals, make sure you’re eating good nutritious foods with plenty of colored vegetables, exercise in moderation, get adequate sleep in the dark, reduce stress as much as possible to lower cortisol-induced estrogen, and take nutritional supplements that bolster the army of antioxidants that protect against environmental toxins that convert good estrogens to bad ones [5,6]. And if your hormones are out of balance, based on testing their levels in body fluids that represent the bioavailable fraction that enters cells, use physiological amounts of bioidentical hormones to adjust them to levels when you were younger and healthy. What has been crystal clear is that bioidentical hormone therapy, if used correctly and in physiological amounts, will significantly reduce risk but is no guarantee you will never develop breast cancer.

Synthetic Progestins Raise Breast Cancer Risk

Fast forward about 20 years to present; several more recent meta-analyses of the risk of breast cancer with FDA-approved, or equivalent for non-US countries, estrogen and progestogen therapies, shed some new light on risk of HRT for breast cancer. These studies (US, British) mostly just reiterated what we already knew: that estrogen therapy only increases breast cancer risk slightly, but significantly when combined with synthetic progestins [1]. The meta-analysis of prospective studies of slightly over 100,000 women using estrogen alone or estrogen combined with progestogens (mostly synthetic), but also oral progesterone [1], revealed that estrogen therapy alone was only associated with a slight increase in risk, but when combined with a synthetic progestin the risk was approximately doubled after 5 years and doubled again at 10 years of use. No question, synthetic progestins were bad for the breasts and should not be used, especially by women who want to reap the many benefits of hormone therapies their entire lives, who should avoid synthetic progestins. Most surprising was that this study also reported that FDA-approved oral bioidentical progesterone, combined with estrogen, carried the same approximately 2-fold higher risk at 5-10 years, but strangely had no increased risk less or greater than that [1]. No data were available for topical progesterone combined with estrogens, perhaps because very few, if any, clinical studies have been carried out in the US or Great Britain and surrounding European countries using natural progesterone delivered topically. 

Topical versus Oral Progesterone

Oral progesterone, while it protects the endometrial lining, may not raise progesterone to a level high enough to counter the growth-promoting actions of estrogens in the breast tissue.

Despite research and small clinical studies showing that natural progesterone delivered topically directly to the breasts of humans [4] and primates protects against estrogen-stimulated cell proliferation of normal mammary epithelial cells, a risk factor for breast cancer, surprisingly no large prospective randomized clinical studies have been carried out to investigate if topical progesterone therapy is associated with reduced risk for developing breast cancer. The reason for this is not based on science, but economics. Progesterone cannot be patented; however, progesterone combined with a special delivery system can be, as seen with several forms of FDA-approved oral progesterone (Prometrium and Bijuva). Oral progesterone, however, while it protects the endometrial lining, may not raise progesterone to a level high enough to counter the growth-promoting actions of estrogens in the breast tissue [7].

Factors Influencing Estrogen Metabolism to Mitigate Risk

What is clear is that anything that reduces excessive estrogen burden, be it progesterone, natural or synthetic aromatase inhibitors, diet with more fiber and phytochemicals with colored vegetables, exercise, stress reduction, better sleep habits, etc., translates to lower breast cancer risk. That is what progesterone does. It lowers cell proliferation by down-regulating estrogen receptors (ER), preventing further estrogen-mediated stimulation of cell proliferation and redirects differentiation through progesterone interaction with estrogen-regulated cellular progesterone receptors (PR). Progesterone, via its activation of 17β-hydroxysteroid dehydrogenase type 2 (see diagram below), also increases the conversion of estradiol, a potent estrogen with high affinity for cellular ERs, to estrone, a weak inert estrogen [3]. Progesterone also enhances synthesis of sulfotransferase, an enzyme that then sulfates estrone to estrone sulfate, which is unable to enter cells and serves as a circulating estrogen precursor that must be converted back through two enzymatic steps, sulfatase and 17β-hydroxysteroid dehydrogenase type 1, to estradiol.

ZRT Laboratory Estrogen Metabolism and Breast Cancer Risk

Diagram depicts the progesterone-regulated metabolism of E2 to E1 and then to E1-SO4, and then Cyp1A1 and Cyp1B1 conversion, respectively, to 2- and 4-hydroxy estrogens and their further oxidation to 2- and 4-quinones. For details see reference [5].

Progesterone’s Effects on Estrogen-Stimulated Cell Proliferation

What is poorly understood in the scientific/clinical community is that progesterone has dual actions in its effects on estrogen-stimulated cell proliferation. At the lower luteal levels (about 1-10 ng/mL) progesterone synergizes with estrogen to promote cell proliferation with little differentiation. If insufficient progesterone is produced in the presence of high estradiol, as often occurs at perimenopause with compromised luteal function, proliferation may be higher than with estradiol alone [7]. However, at higher luteal levels (10-30 ng/mL) progesterone counters the growth-promoting actions of estrogen by down-regulating ER, and through induction of cellular PR redirects the cellular machinery to drive quiescence and differentiation, causing proliferation to come to a halt. If inadequate progesterone is present, as often happens at the transition to menopause (perimenopause) when the corpus luteum fails to produce adequate progesterone but abundant estrogen (low progesterone/estradiol ratio), then the combination of higher physiological estrogen and lower luteal progesterone (in range, but low-normal) will often result in persistent proliferation and the clinical manifestation of fibrocystic and painful breasts. Excessive proliferation in the absence of progesterone increases risk for gene mutations that have the potential to lead to increased breast cancer risk. 

Risks Greatest During the Menopausal Transition

Retrospective clinical studies have shown that the higher the luteal progesterone level 5 years prior to breast cancer diagnosis, the lower the risk of developing breast cancer.

As shown in the diagram above, estrogens in excess, in the absence of progesterone and with exposure to environmental toxins, induce the cytochrome enzyme Cyp1B1 that converts beneficial estradiol to potentially toxic and mutagenic 4-catechol estradiol [5,6]. During this perimenopausal transition is when the rate of increase of breast cancer is greatest. Retrospective clinical studies have shown that the higher the luteal progesterone level 5 years prior to breast cancer diagnosis, the lower the risk of developing breast cancer [8], so it is important to keep progesterone balanced with estradiol, especially during the menopause transition when estrogen metabolite damage is most likely to occur, as shown in a recent study on estrogen metabolite formation and breast cancer risk [6].

Topical Progesterone Achieves Optimal Tissue Levels

As mentioned, oral progesterone, because it is mostly degraded (90-95%) in the GI tract and liver to metabolites with no capacity to bind and activate PR, may not reach sustained luteal levels to counter the growth-promoting actions of estrogens. Based on saliva, capillary blood, and tissue levels of progesterone, only topically applied progesterone [9] can achieve capillary blood and tissue levels of progesterone high enough to counter the proliferative actions of estrogens. While small clinical studies have shown that topical progesterone used at physiological dosing (25-50 mg) effectively reduces estrogen-induced proliferation of the mammary epithelium in humans [4], this form of therapy has not been tested in a large scale prospective case-control randomized study as with FDA-approved conjugated equine estrogens in combination with synthetic progestins [1,2].

What might we learn from what we know about the dual actions of progesterone as it relates to bioidentical estrogen and progesterone therapies for menopausal women and their risk for breast cancer? If we let mother nature be our guide, then we should strive to keep estrogen within the physiological ranges seen throughout a full monthly cycle (about 50-150 pg/mL in serum or about 2% of that seen in saliva, 1-3 pg/mL). For at least half of the month serum or capillary blood (Dried Blood Spot, DBS) progesterone should be about 10-30 ng/mL and saliva 200-600 pg/mL. This results in a progesterone/estradiol ratio of about 100-300, which is consistent with the ratio seen at the peak of the luteal phase and shown to be protective of the breasts exposed to estradiol [4]. Excessive estradiol or too little progesterone will result eventually in estrogen dominance and symptoms of estrogen excess (e.g., weight gain in the hips and thighs, fibrocystic and painful breasts, mood swings, etc.) Those are warning signs. High levels of 4-catechol estrogens ratchet that up to extreme warning [5] as we have found that 4-catechol estrogens are much higher in women harboring breast cancers than healthy women [6]

Many providers believe that topical progesterone is ineffective because it doesn’t raise serum levels. To the contrary, we [9] and others [4,10] have shown that physiological dosing with topically delivered progesterone raises the progesterone to physiological levels in tissues of the body such as the salivary gland, and capillary beds of the finger tips. High dose progesterone (> 50 mg), in an attempt to achieve physiological concentrations in serum never does this, regardless of the topical progesterone dose [9]. What may seem paradoxical based on serum levels is that excessive progesterone and too little estrogen will eventually keep ER persistently down-regulated and may precipitate symptoms of estrogen deficiency with weight gain, vasomotor symptoms, excessive sleepiness, etc. Keep in mind that estradiol and progesterone are produced in a rhythmic pattern each month. Estradiol rises slowly throughout the first half of the cycle and peaks about midway with ovulation. This stimulates growth and proliferation of the uterus and breasts. Progesterone will not work if there is no cellular PR, which requires adequate ER. Excessive progesterone down-regulates ER, stopping the cycle.

In summary, maintaining estradiol levels in balance with natural progesterone is necessary to achieve optimal clinical benefits of these hormones. It is the opinion of this author that these goals for optimal progesterone therapy as a breast cancer preventive can best be achieved with topical progesterone, and not oral progesterone, or a synthetic progestin. However, clinical studies with topical progesterone are needed to confirm this hypothesis.

While you go through the stages of menopause, it is important to get your hormone levels checked to ensure that you are within physiological levels. If you are going into, in the middle of, or at the end of your menopause journey, ZRT’s saliva and blood spot testing can give you the information necessary to get your hormones balanced and get you back to optimal health.
