I used to suppose low progesterone was one thing that occurred to my shoppers however really wouldn’t occur to me lol.
I had heard the tales, had helped girls work by means of the signs, and understood the physiology. After which, someday in my early 40s, it occurred anyway. Rapidly, I turned inexplicably irritable and rage-y in a manner that didn’t really feel like me. My sleep – which had all the time been one in every of my superpowers – fell aside nearly in a single day. I went from sleeping like a cheerful child to tossing and turning, conscious at 2am with a racing thoughts and a low hum of hysteria I couldn’t shake.
I ran some practical lab testing and located that my progesterone was on the ground. I shouldn’t have been stunned, as a result of it’s extremely widespread for girls of their late 30s and 40s and sometimes goes utterly unidentified as a result of the signs seem like stress, burnout, or simply “getting older.”
If any of this sounds acquainted, this publish is for youuuuuu. As an Integrative Health Practitioner and ladies’s health specialist, I need to chat with ya about what low progesterone seems to be like, why it occurs, the right way to check for it correctly, and what you possibly can really do about it – naturally and past. (pleasant reminder that that is NOT medical recommendation. As all the time, speak to your physician earlier than making any adjustments along with your routine.)

What Progesterone Truly Does
Earlier than we discuss what occurs when progesterone is low, it helps to know why this hormone issues a lot within the first place.
Progesterone is commonly referred to as the calming hormone, and for good cause. It really works as a pure counterbalance to estrogen – whereas estrogen is stimulating and growth-promoting, progesterone is stabilizing and protecting. It’s produced primarily after ovulation, through the second half of your menstrual cycle (referred to as the luteal part), and it does a outstanding variety of issues within the physique:
- Helps deep, restorative sleep by changing to a compound referred to as allopregnanolone, which prompts the mind’s calming GABA receptors
- Acts as a pure anti-anxiety agent by means of those self same GABA pathways
- Regulates temper and reduces PMS signs
- Helps keep common menstrual cycles
- Protects in opposition to estrogen dominance
- Has anti-inflammatory and neuroprotective properties
- Helps thyroid operate
- Has anti-growth and anti-tumor properties, making it genuinely protecting for long-term well being
When progesterone begins to say no, which occurs steadily all through our 30s and extra dramatically as we method perimenopause, all of those features are affected. That’s the reason the signs can really feel so widespread and complicated.
Indicators and Signs of Low Progesterone
That is the listing I want somebody had handed me years in the past! Low progesterone can present up in so many ways in which girls usually chalk it as much as stress or ageing reasonably than recognizing it as a hormone challenge.
Sleep Issues
This was my largest sign. Progesterone helps your mind wind down and keep in deeper levels of sleep. When ranges drop, sleep turns into lighter, extra fragmented, and fewer restorative. Many ladies discover they wake between 2am and 4am and can’t fall again asleep. If in case you have gone from a strong sleeper to somebody who dreads bedtime, low progesterone is value investigating.
Anxiousness and Irritability
As a result of progesterone helps GABA exercise within the mind, low ranges can really feel like a low-grade anxiousness that appears to return from nowhere – or a brief fuse and emotional reactivity that doesn’t really feel such as you. I describe my expertise as feeling rage-y in a manner that was genuinely out of character. If you end up snapping extra simply, feeling on edge, or experiencing a type of free-floating fear, it is a traditional low progesterone sample, particularly whether it is worse within the second half of your cycle.
Quick Menstrual Cycles
This one is a key scientific signal that doesn’t get talked about sufficient. Progesterone is simply produced after ovulation, so in case your luteal part (the time between ovulation and your interval) is shrinking, your progesterone is probably going low. Cycles which might be 24 to 25 days lengthy as an alternative of 28 to 30 are sometimes an indication of a shortened luteal part and insufficient progesterone. My very own cycles had shortened noticeably earlier than I obtained my ranges examined and as soon as I addressed my progesterone, they normalized again to twenty-eight days.
Worsening PMS
In case your premenstrual signs are getting worse with age – extra bloating, extra breast tenderness, extra temper swings, extra cramps – that’s usually a progesterone story. PMS intensifies when estrogen isn’t being adequately balanced by progesterone within the luteal part.
Heavy or Irregular Intervals
Progesterone stabilizes the uterine lining. With out sufficient of it, the liner can construct up excessively (because of unopposed estrogen), resulting in heavier bleeding, clotting, or recognizing between intervals.
Scorching Flashes
Scorching flashes are usually not only a menopause symptom – they will present up throughout perimenopause when progesterone is declining, even when estrogen remains to be comparatively regular. In case you are in your late 30s or early 40s and experiencing heat or flushing, it’s value taking a look at your full hormone image.
Low Libido
Progesterone performs a job in sexual curiosity and drive. Low ranges can present up as a normal disinterest in intercourse, particularly within the second half of your cycle.
Weight Achieve and Bloating
With out progesterone’s balancing impact, estrogen can promote fluid retention and fats storage, significantly across the midsection. In case your weight has been creeping up with out clear rationalization, hormones could also be a part of the image.
Complications and Migraines
Progesterone has vascular and neuroprotective properties. When it dips within the luteal part, many ladies discover a rise in complications or menstrual migraines.
Fatigue
Poor sleep plus hormonal imbalance equals exhaustion. In case you are drained regardless of how a lot relaxation you get, and the fatigue is worse within the weeks earlier than your interval, low progesterone could possibly be a contributing issue.


What Causes Progesterone to Drop
Understanding the basis causes issues, as a result of when you solely handle signs with out addressing causes, you’re going to maintain working uphill.
Listed here are the most typical drivers I see in my apply:
Persistent Stress (This Is the Large One)
Your physique has to really feel secure to make progesterone. That’s not only a good concept; it’s physiology. If you end up chronically burdened, your adrenal glands prioritize producing cortisol, your main stress hormone. The issue is that cortisol and progesterone share the identical hormonal constructing block (pregnenolone), and when cortisol demand is excessive, the physique primarily steals from progesterone manufacturing to maintain up. That is generally referred to as the “pregnenolone steal” and it is among the most typical drivers of low progesterone I see, particularly in high-achieving, always-on girls.
Stress doesn’t simply imply emotional overwhelm both. Undereating, over-exercising, poor sleep, and poisonous exposures all rely as physiological stress. Your physique can not inform the distinction between a deadline and a famine – it simply is aware of it doesn’t really feel secure, and it downregulates reproductive hormones accordingly.
Perimenopause and Growing older
Progesterone is definitely the primary hormone to say no as we method perimenopause, usually beginning in our mid-30s, years earlier than estrogen drops and earlier than intervals develop into irregular. That is why so many ladies of their late 30s and 40s begin experiencing signs they can not clarify. Their estrogen should be completely regular, however the progesterone that needs to be balancing it has quietly began declining.
Anovulatory Cycles
Progesterone is simply made after ovulation. In case you are not ovulating (which may occur because of stress, undereating, thyroid points, or PCOS), you aren’t producing significant progesterone – even when your cycle seems common on the surface.
Intestine Imbalances
This connection is underappreciated however actually vital. Hormones together with progesterone are produced and transformed partly by means of the intestine. If there are imbalances in your intestine microbiome – dysbiosis, leaky intestine, poor elimination – your physique’s capacity to correctly produce, use, and clear hormones is compromised. A selected assortment of intestine micro organism referred to as the estrobolome is answerable for metabolizing estrogen. When it’s disrupted, estrogen can recirculate reasonably than clear, making a relative progesterone deficiency even when progesterone itself isn’t technically low.
Thyroid Dysfunction
The thyroid and reproductive hormones are deeply related. Low thyroid operate can impair ovulation and scale back progesterone manufacturing, which is why thyroid testing ought to all the time be a part of a hormone workup.
Find out how to Check Your Progesterone Ranges (and Why Timing Issues)
Right here is one thing I really feel strongly about: most standard progesterone testing is finished incorrectly, and this results in lots of girls being instructed their ranges are “regular” when they’re really struggling.
Many medical doctors order a blood check for progesterone at a random level within the cycle – and even on day 3 alongside estrogen and FSH. However progesterone fluctuates dramatically throughout the cycle. Testing it on the incorrect time tells you nearly nothing. Progesterone is of course low within the first half of your cycle (the follicular part), so a low consequence drawn on day 5 is totally anticipated and never diagnostic of an issue.
The precise time to check is through the mid-luteal part, round days 19 to 21 of a 28-day cycle. That is when progesterone needs to be at its peak, and it’s the solely time a low consequence is definitely significant.
Why I Choose Saliva Testing
Past timing, I additionally want saliva testing over blood testing for progesterone, and right here is why. Nearly the entire progesterone circulating within the bloodstream is certain to service proteins, which suggests it isn’t bioavailable – it can not really act in your cells. Saliva testing measures the free, unbound hormone that’s obtainable to do its job within the physique. It provides you a way more correct image of what your tissues are literally experiencing.
If you wish to dig into your hormone well being with actual information reasonably than guessing, testing is the place to begin.
Find out how to Assist Progesterone Naturally
Whether or not you might be within the early levels of noticing signs or actively working to rebuild your ranges, there’s a lot you are able to do. I all the time begin with foundations earlier than reaching for dietary supplements, as a result of foundations are what make the whole lot else work.
Prioritize Stress Administration (Non-Negotiable)
I do know “handle your stress” feels like recommendation you’ve gotten heard a thousand instances. However in terms of progesterone particularly, it isn’t optionally available. In case your nervous system is in power fight-or-flight mode, your physique goes to maintain prioritizing cortisol over progesterone, interval. It’s a must to give your physique the sign that it’s secure.
What this seems to be like in apply:
- A constant sleep schedule (your physique makes hormones on a schedule)
- Every day parasympathetic exercise – walks, breathwork, mild yoga, meditation, time in nature
- Not over-exercising (high-intensity coaching on daily basis is a stressor, particularly for girls with hormone imbalances)
- Consuming sufficient – power undereating is a significant hormonal stressor that many health-conscious girls overlook


Eat to Assist Progesterone: Fruits and Roots
A easy framework I really like for progesterone assist is “fruits and roots.” This refers back to the sorts of entire, nourishing meals that present the uncooked supplies your physique must make and regulate hormones.
Key vitamins for progesterone manufacturing:
- Vitamin C: The ovaries include among the highest concentrations of vitamin C within the physique, and it performs a direct function in progesterone synthesis. Suppose citrus fruits, kiwi, pink bell peppers, strawberries, and broccoli.
- Vitamin B6: Helps hormone steadiness and helps the liver clear extra estrogen. Present in chickpeas, bananas, potatoes, poultry, and leafy greens.
- Zinc: Stimulates the pituitary to launch FSH, which helps ovulation and subsequently progesterone manufacturing. Pumpkin seeds, cashews, and grass-fed beef are nice sources.
- Magnesium: Helps decrease extra estrogen and helps progesterone not directly. Present in leafy greens, darkish chocolate, pumpkin seeds, and avocado. Most girls are poor and profit from supplementing with magnesium glycinate. This is my favorite magnesium.
- Wholesome fat: Hormones are constructed from ldl cholesterol, so that you want enough wholesome fat to supply them. Avocado, olive oil, fatty fish, nuts, and seeds are your pals.
Root greens – candy potato, yam, squash, beets – are additionally great as a result of they supply steady, complicated carbohydrates that assist blood sugar steadiness, which in flip helps wholesome hormone rhythms.
Assist Your Intestine
As a result of hormones are produced and transformed within the intestine, intestine well being is hormone well being. Concentrate on fiber (particularly from greens and legumes), fermented meals like sauerkraut and kefir if tolerated, and lowering issues that disrupt the intestine microbiome like alcohol, processed meals, and pointless antibiotic use. In the event you suspect deeper intestine points, practical testing might be extremely eye-opening.
Think about Seed Biking
Seed biking is a apply of consuming particular seeds throughout every part of your menstrual cycle to assist hormone manufacturing and steadiness. Through the second half of your cycle (the luteal part, days 15 to twenty-eight), sesame seeds and sunflower seeds are historically used to assist progesterone. It’s a mild, food-based method that many ladies discover useful, particularly when mixed with different life-style adjustments.
Natural Assist
A number of herbs have a protracted historical past of supporting progesterone and general hormone steadiness. Vitex (additionally referred to as chasteberry) is among the most well-researched. It really works by supporting the pituitary’s launch of LH, which stimulates ovulation and subsequently progesterone manufacturing. It’s usually finest fitted to premenopausal girls with luteal part points reasonably than girls who’re already in perimenopause or past.
I used herbal support as my first step once I seen my progesterone declining, and it labored nicely for a time period. Herbs could be a nice place to begin, particularly for girls who’re earlier within the hormonal transition.


When Pure Assist Is Not Sufficient
I need to be actual with you right here, as a result of I believe there may be generally pointless stigma round hormone assist, and I’ve lived this personally.
I began with natural assist and it helped for some time. However as my ranges continued to say no, I finally transitioned to topical progesterone, and it has genuinely modified my high quality of life. I exploit Raena, which I really like, and I solely use it through the second half of my cycle – the luteal part. The distinction has been outstanding. I sleep so deeply throughout this time. I really feel calm and even in a manner that I had began to suppose was simply gone. My cycles normalized from 24 to 25 days again to a full 28 days.
Bioidentical topical progesterone isn’t the scary factor it’s generally made out to be – particularly when utilized in physiologic doses to revive what your physique is now not making by itself. I want extra girls knew that this feature exists and that it doesn’t must really feel like a final resort. Getting your ranges examined first is vital, so you realize what you might be working with and might monitor your response over time.
In case you are undecided the place to begin with all of this, working with a practitioner who understands practical hormone testing and bioidentical hormone assist can prevent years of guessing. That is precisely the type of work I do with my 1:1 shoppers – connecting your signs to your lab information and constructing a personalised plan from there.

Is low progesterone widespread in perimenopause?
Extraordinarily widespread and it’s usually the primary hormone to say no, generally years earlier than estrogen drops or intervals develop into irregular.
