I used to suppose low progesterone was one thing that occurred to my purchasers however truly wouldn’t occur to me lol.
I had heard the tales, had helped girls work via the signs, and understood the physiology. After which, someday in my early 40s, it occurred anyway. Unexpectedly, I grew to become inexplicably irritable and rage-y in a approach that didn’t really feel like me. My sleep – which had at all times been one among my superpowers – fell aside nearly in a single day. I went from sleeping like a contented child to tossing and turning, conscious at 2am with a racing thoughts and a low hum of tension 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 frequent for ladies of their late 30s and 40s and infrequently goes utterly unidentified as a result of the signs appear to be stress, burnout, or simply “getting older.”
If any of this sounds acquainted, this submit is for youuuuuu. As an Integrative Well being Practitioner and ladies’s health specialist, I need to chat with ya about what low progesterone seems to be like, why it occurs, take a look at for it correctly, and what you’ll be able to truly do about it – naturally and past. (pleasant reminder that that is NOT medical recommendation. As at all times, speak to your physician earlier than making any adjustments together with your routine.)

What Progesterone Truly Does
Earlier than we speak about what occurs when progesterone is low, it helps to grasp 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, throughout the second half of your menstrual cycle (referred to as the luteal section), and it does a exceptional 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 via 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 perform
Has anti-growth and anti-tumor properties, making it genuinely protecting for long-term well being
When progesterone begins to say no, which occurs regularly 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 record 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 getting old reasonably than recognizing it as a hormone concern.
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 stable sleeper to somebody who dreads bedtime, low progesterone is price investigating.
Nervousness 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 come back 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 approach 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 basic low progesterone sample, particularly whether it is worse within the second half of your cycle.
Brief Menstrual Cycles
This one is a key scientific signal that doesn’t get talked about sufficient. Progesterone is just produced after ovulation, so in case your luteal section (the time between ovulation and your interval) is shrinking, your progesterone is probably going low. Cycles which are 24 to 25 days lengthy as a substitute of 28 to 30 are sometimes an indication of a shortened luteal section and insufficient progesterone. My very own cycles had shortened noticeably earlier than I acquired 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 will not be being adequately balanced by progesterone within the luteal section.
Heavy or Irregular Durations
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.
Sizzling Flashes
Sizzling flashes aren’t only a menopause symptom – they will present up throughout perimenopause when progesterone is declining, even when estrogen remains to be comparatively regular. If you’re in your late 30s or early 40s and experiencing heat or flushing, it’s price your full hormone image.
Low Libido
Progesterone performs a task in sexual curiosity and drive. Low ranges can present up as a basic disinterest in intercourse, particularly within the second half of your cycle.
Weight Acquire 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 clarification, hormones could also be a part of the image.
Complications and Migraines
Progesterone has vascular and neuroprotective properties. When it dips within the luteal section, many ladies discover a rise in complications or menstrual migraines.
Fatigue
Poor sleep plus hormonal imbalance equals exhaustion. If you’re drained irrespective 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 foundation causes issues, as a result of in case you solely tackle signs with out addressing causes, you’re going to preserve operating uphill.
Listed here are the most typical drivers I see in my apply:
Continual Stress (This Is the Massive One)
Your physique has to really feel secure to make progesterone. That’s not only a good thought; it’s physiology. When you’re chronically pressured, 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 without doubt one of the commonest 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 depend as physiological stress. Your physique can’t 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 Ageing
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 grow to be irregular. Because of this 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 ought to be balancing it has quietly began declining.
Anovulatory Cycles
Progesterone is just made after ovulation. If you’re not ovulating (which might occur resulting from 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 essential. Hormones together with progesterone are produced and transformed partly via the intestine. If there are imbalances in your intestine microbiome – dysbiosis, leaky intestine, poor elimination – your physique’s skill 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 will not be technically low.
Thyroid Dysfunction
The thyroid and reproductive hormones are deeply related. Low thyroid perform can impair ovulation and cut back progesterone manufacturing, which is why thyroid testing ought to at all times be a part of a hormone workup.
The right way to Take a look at 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 plenty of girls being advised their ranges are “regular” when they’re truly struggling.
Many medical doctors order a blood take a look at 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 unsuitable time tells you nearly nothing. Progesterone is of course low within the first half of your cycle (the follicular section), so a low end result drawn on day 5 is totally anticipated and never diagnostic of an issue.
The appropriate time to check is throughout the mid-luteal section, round days 19 to 21 of a 28-day cycle. That is when progesterone ought to be at its peak, and it’s the solely time a low end result is definitely significant.
Why I Choose Saliva Testing
Past timing, I additionally favor saliva testing over blood testing for progesterone, and right here is why. Nearly the entire progesterone circulating within the bloodstream is sure to provider proteins, which suggests it isn’t bioavailable – it can’t truly act in your cells. Saliva testing measures the free, unbound hormone that’s accessible to do its job within the physique. It offers 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 knowledge reasonably than guessing, testing is the place to begin.
The right way to Help 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 at all times begin with foundations earlier than reaching for dietary supplements, as a result of foundations are what make all the pieces else work.
Prioritize Stress Administration (Non-Negotiable)
I do know “handle your stress” appears like recommendation you will have heard a thousand occasions. However relating to progesterone particularly, it isn’t non-obligatory. In case your nervous system is in persistent fight-or-flight mode, your physique goes to maintain prioritizing cortisol over progesterone, interval. You must 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, light yoga, meditation, time in nature
Not over-exercising (high-intensity coaching day by day is a stressor, particularly for ladies with hormone imbalances)
Consuming sufficient – persistent undereating is a significant hormonal stressor that many health-conscious girls overlook

Eat to Help Progesterone: Fruits and Roots
A easy framework I 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 a number of the highest concentrations of vitamin C within the physique, and it performs a direct position in progesterone synthesis. Assume citrus fruits, kiwi, purple bell peppers, strawberries, and broccoli.
Vitamin B6: Helps hormone stability 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 due to this fact 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. That is my favourite magnesium.
Wholesome fat: Hormones are constructed from ldl cholesterol, so that you want ample wholesome fat to provide them. Avocado, olive oil, fatty fish, nuts, and seeds are your folks.
Root greens – candy potato, yam, squash, beets – are additionally fantastic as a result of they supply secure, advanced carbohydrates that assist blood sugar stability, which in flip helps wholesome hormone rhythms.
Help 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 decreasing issues that disrupt the intestine microbiome like alcohol, processed meals, and pointless antibiotic use. Should you suspect deeper intestine points, practical testing might be extremely eye-opening.
Take into account Seed Biking
Seed biking is a apply of consuming particular seeds throughout every section of your menstrual cycle to assist hormone manufacturing and stability. Throughout the second half of your cycle (the luteal section, days 15 to twenty-eight), sesame seeds and sunflower seeds are historically used to assist progesterone. It’s a light, food-based method that many ladies discover useful, particularly when mixed with different life-style adjustments.
Natural Help
A number of herbs have an extended historical past of supporting progesterone and general hormone stability. Vitex (additionally referred to as chasteberry) is without doubt one of the most well-researched. It really works by supporting the pituitary’s launch of LH, which stimulates ovulation and due to this fact progesterone manufacturing. It’s usually greatest suited to premenopausal girls with luteal section points reasonably than girls who’re already in perimenopause or past.
I used natural assist as my first step once I observed my progesterone declining, and it labored effectively for a time period. Herbs generally is a nice start line, particularly for ladies who’re earlier within the hormonal transition.

When Pure Help Is Not Sufficient
I need to be actual with you right here, as a result of I feel there’s 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 ultimately transitioned to topical progesterone, and it has genuinely modified my high quality of life. I exploit Raena, which I like, and I solely use it throughout the second half of my cycle – the luteal section. The distinction has been exceptional. I sleep so deeply throughout this time. I really feel calm and even in a approach 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 will not be the scary factor it’s generally made out to be – particularly when utilized in physiologic doses to revive what your physique is not making by itself. I want extra girls knew that this selection exists and that it doesn’t should really feel like a final resort. Getting your ranges examined first is vital, so you already know what you might be working with and may monitor your response over time.
If you’re unsure 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 purchasers – connecting your signs to your lab knowledge and constructing a personalised plan from there.
