I used to suppose low progesterone was one thing that occurred to my purchasers however really wouldn’t occur to me lol.
I had heard the tales, had helped ladies work via the signs, and understood the physiology. After which, someday in my early 40s, it occurred anyway. Abruptly, 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 considered one of my superpowers – fell aside nearly in a single day. I went from sleeping like a contented child to tossing and turning, wakeful 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 shocked, as a result of it’s extremely widespread for girls of their late 30s and 40s and infrequently goes utterly unidentified as a result of the signs appear like stress, burnout, or simply “getting older.”
If any of this sounds acquainted, this put up is for youuuuuu. As an Integrative Well being Practitioner and ladies’s health specialist, I need to chat with ya about what low progesterone appears like, why it occurs, how you can check for it correctly, and what you may really do about it – naturally and past. (pleasant reminder that that is NOT medical recommendation. As all the time, discuss to your physician earlier than making any modifications together with your routine.)

What Progesterone Truly Does
Earlier than we speak about what occurs when progesterone is low, it helps to know why this hormone issues a lot within the first place.
Progesterone is usually 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 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 via those self same GABA pathways
- Regulates temper and reduces PMS signs
- Helps preserve common menstrual cycles
- Protects towards 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 capabilities 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 ladies usually chalk it as much as stress or growing old moderately than recognizing it as a hormone problem.
Sleep Issues
This was my greatest 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. In case you have gone from a stable sleeper to somebody who dreads bedtime, low progesterone is value investigating.
Nervousness and Irritability
As a result of progesterone helps GABA exercise within the mind, low ranges can really feel like a low-grade nervousness 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 manner that was genuinely out of character. If you end up snapping extra simply, feeling on edge, or experiencing a sort of free-floating fear, this can be 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 medical 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 received 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 is just not being adequately balanced by progesterone within the luteal part.
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 durations.
Scorching Flashes
Scorching flashes will not be 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 value taking a look at your full hormone image.
Low Libido
Progesterone performs a task in sexual curiosity and drive. Low ranges can present up as a common 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, notably 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. If you’re drained regardless of how a lot relaxation you get, and the fatigue is worse within the weeks earlier than your interval, low progesterone might be a contributing issue.

What Causes Progesterone to Drop
Understanding the foundation causes issues, as a result of if you happen to solely deal with signs with out addressing causes, you’re going to preserve working uphill.
Listed here are the commonest drivers I see in my follow:
Power Stress (This Is the Massive One)
Your physique has to really feel protected to make progesterone. That isn’t only a good concept; it’s physiology. If you find yourself chronically careworn, your adrenal glands prioritize producing cortisol, your major stress hormone. The issue is that cortisol and progesterone share the identical hormonal constructing block (pregnenolone), and when cortisol demand is excessive, the physique basically steals from progesterone manufacturing to maintain up. That is typically referred to as the “pregnenolone steal” and it is among the commonest drivers of low progesterone I see, particularly in high-achieving, always-on ladies.
Stress doesn’t simply imply emotional overwhelm both. Undereating, over-exercising, poor sleep, and poisonous exposures all depend 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 protected, and it downregulates reproductive hormones accordingly.
Perimenopause and Getting old
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 durations change into irregular. Because of this so many ladies of their late 30s and 40s begin experiencing signs they can’t clarify. Their estrogen should still be completely regular, however the progesterone that must be balancing it has quietly began declining.
Anovulatory Cycles
Progesterone is simply 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 vital. 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 capability to correctly produce, use, and clear hormones is compromised. A particular assortment of intestine micro organism referred to as the estrobolome is chargeable for metabolizing estrogen. When it’s disrupted, estrogen can recirculate moderately than clear, making a relative progesterone deficiency even when progesterone itself is just not technically low.
Thyroid Dysfunction
The thyroid and reproductive hormones are deeply linked. 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.
Check Your Progesterone Ranges (and Why Timing Issues)
Right here is one thing I really feel strongly about: most typical progesterone testing is finished incorrectly, and this results in quite a lot of ladies being informed 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 unsuitable 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 throughout the mid-luteal part, round days 19 to 21 of a 28-day cycle. That is when progesterone must be at its peak, and it’s the solely time a low consequence is definitely significant.
Why I Desire Saliva Testing
Past timing, I additionally choose saliva testing over blood testing for progesterone, and right here is why. Nearly the entire progesterone circulating within the bloodstream is certain to provider proteins, which implies it’s not 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 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 information moderately than guessing, testing is the place to start out.
Assist Progesterone Naturally
Whether or not you’re 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 all the things else work.
Prioritize Stress Administration (Non-Negotiable)
I do know “handle your stress” feels like recommendation you could have heard a thousand instances. However in the case of progesterone particularly, it’s not elective. In case your nervous system is in power fight-or-flight mode, your physique goes to maintain prioritizing cortisol over progesterone, interval. You must give your physique the sign that it’s protected.
What this appears like in follow:
- A constant sleep schedule (your physique makes hormones on a schedule)
- Day by day parasympathetic exercise – walks, breathwork, mild yoga, meditation, time in nature
- Not over-exercising (high-intensity coaching daily is a stressor, particularly for girls with hormone imbalances)
- Consuming sufficient – power undereating is a serious hormonal stressor that many health-conscious ladies overlook

Eat to Assist Progesterone: Fruits and Roots
A easy framework I really like for progesterone help 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 comprise a few of 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 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 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. That is my favourite magnesium.
- Wholesome fat: Hormones are constructed from ldl cholesterol, so that you want sufficient wholesome fat to supply them. Avocado, olive oil, fatty fish, nuts, and seeds are your mates.
Root greens – candy potato, yam, squash, beets – are additionally fantastic as a result of they supply secure, complicated carbohydrates that help blood sugar stability, 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. Give attention to 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. Should you suspect deeper intestine points, practical testing could be extremely eye-opening.
Think about Seed Biking
Seed biking is a follow of consuming particular seeds throughout every part of your menstrual cycle to help hormone manufacturing and stability. In the course of the second half of your cycle (the luteal part, days 15 to twenty-eight), sesame seeds and sunflower seeds are historically used to help progesterone. It’s a mild, food-based method that many ladies discover useful, particularly when mixed with different way of life modifications.
Natural Assist
A number of herbs have a protracted historical past of supporting progesterone and general hormone stability. 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 typically finest fitted to premenopausal ladies with luteal part points moderately than ladies who’re already in perimenopause or past.
I used natural help as my first step after I seen my progesterone declining, and it labored effectively 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 feel there’s typically pointless stigma round hormone help, and I’ve lived this personally.
I began with natural help 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 take advantage of Raena, which I really like, and I solely use it throughout 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 is just not the scary factor it’s typically made out to be – particularly when utilized in physiologic doses to revive what your physique is not making by itself. I want extra ladies knew that this selection exists and that it doesn’t need to really feel like a final resort. Getting your ranges examined first is vital, so you realize what you’re working with and might observe your response over time.
If you’re undecided the place to start out with all of this, working with a practitioner who understands practical hormone testing and bioidentical hormone help can prevent years of guessing. That is precisely the sort of work I do with my 1:1 purchasers – connecting your signs to your lab information and constructing a personalised plan from there.
