This is the Reason Your Progesterone is Low


Please note - if you are peri/post menopausal, you likely need more support than nutrition and lifestyle interventions. Discussing your concerns with your doctor and/or functional practitioner are key for getting the support you need.

Low progesterone is common in the stressful world we live in. When our bodies are in a stressed state, it does not prioritize hormone production, including the production of progesterone. Chronic stress also negatively impacts communication from the brain to the ovaries, which can reduce how much progesterone is produced, even if you are ovulating. 

However, common does not mean normal, and consistent low progesterone levels are not the state that our bodies should be functioning in. Understanding the signs and root causes of low progesterone, along with what can be done to improve progesterone levels, is important for your overall health. 


Signs of low progesterone

Recognizing when our progesterone is low is the first step in improving our progesterone levels. A number of symptoms can point toward low progesterone levels, including commonly known symptoms like hot flashes, PMS symptoms, or menstrual cramps. However, did you know there are a number of other symptoms that can also be caused by low progesterone, including: 

  • Facial hair growth and hair loss
  • Breast tenderness
  • Infertility
  • Recurrent miscarriages
  • Irregular cycles
  • Spotting between cycles
  • Heavy periods
  • High blood sugar levels
  • Low libido
  • Fluid retention/bloating
  • Weight gain
  • Low body temperature
  • Hypothyroidism
  • Insomnia
  • Headaches/migr
  • Pain/inflammation
  • Fibroids/cysts
  • Anxiety
  • Depression
  • Irritability/mood swings
  • Sugar cravings
  • Osteoporosis

As you can see, so many of these symptoms can be symptoms of other conditions, as well. That’s why it’s important to work with a healthcare provider to identify the root cause of your condition, should it be low progesterone or another condition entirely. 

Possible Root Causes of Low Progesterone

Identifying the symptoms of low progesterone is only useful if we are then able to identify what is causing it. Clearly identifying the root cause of low progesterone is important, not only for your fertility and menstrual health, but also for your overall well being and general health, too. Hormone production is an important function of our body, and low progesterone can be a sign that something is not functioning just right. 


Possible root causes of low progesterone include: 

  • Lack of ovulation
  • Low fat diet
  • Too little body fat
  • Chronic stress
  • HPA Axis dysfunction
  • High prolactin
  • Hysterectomy
  • Nutrient deficiencies
  • Digestive dysfunction
  • Poor absorption
  • Hormonal birth control
  • Poor ovary function
  • Pituitary dysfunction
  • Thyroid dysfunction
  • Certain medications


Low progesterone is not always a direct result of a reproductive issue. Often, it can be a result of a number of other factors, so identifying the root cause for you is important in creating a plan of treatment. 


⁣Now what? 

Luckily there are a number of things you can do to improve progesterone levels naturally, especially once you get to the bottom of what's causing the low levels in the first place. ⁣⁣Here are my favorite tips for improving progesterone levels through diet, activity, and supplementation. 

  1. Eat more B6 rich foods, such as animal proteins, carrots, sweet potatoes, chicken livers, spinach, and chickpeas. B6 has been shown to help improve progesterone levels, so being sure to get enough B6 in your diet is important. 
  2. Increase your intake of magnesium through foods such as cacao, avocado, leafy greens, plantains, and bananas. 
  3. Increase your healthy fats, such as coconut, olives, avocado, grass-fed or pasture-raised meats, and wild caught fish. Healthy fats are important in the production of hormones in our bodies.
  4. Manage your mental and emotional stress, along with physical stress related to things like exercise and activity. Managing stress can help your body prioritize hormone production. 
  5. Maintain healthy levels of nutrients needed for progesterone production, and look to supplement those that you are low in, such as selenium, magnesium, zinc, and vitamins A, E, C, and B6. 
  6. Support your digestive health so you can properly break down and absorb your foods. Relaxing before meals with a few deep breaths and digestive bitters is a gentle and safe way to do this. 


Let’s dig a little deeper...

One of the most common questions I got was how to naturally increase progesterone. And to be honest, this is a loaded question. It's not a magical food or supplement. Progesterone is hugely impacted by stress, so I'm breaking down the basics here before working with you to figure out your personal needs!

Step 1: Ovulation & Tracking Your Cycle

The first step of naturally boosting progesterone is to make sure you're ovulating every cycle. Ovulation occurs when estrogen surges, and the dominant follicle releases an egg. This is the main event of the menstrual cycle and allows our bodies to balance estrogen and progesterone.  

What often happens when we don't have adequate progesterone is the body is in a stressed state and making more estrogen and less progesterone. When these two are out of balance we experience things like severe PMS symptoms, mood changes, menstrual headaches (or headaches around ovulation), spotting (around ovulation as well), digestive issues, heavy, painful periods, etc. 

Tracking Ovulation

To confirm that ovulation has occurred during your cycle, you need to track your basal body temperature. All you need for this is any basal body thermometer. This means it needs to go to the 100th degree (98.67 vs. 98.6). You can find these at places like CVS, Walgreens, Walmart, and Amazon. 

What You're Looking For

We want to see a temperature increase in the second half of the cycle. Once ovulation occurs, the body makes progesterone, and this increases our basal body temperature. It's not a huge temperature increase that you're looking for. It's only about .5F, but when you chart in an app, you can see the difference. See the chart below from Fertility Friend. You need three high temperatures in a row that are higher than the previous 5 to confirm that ovulation has occurred. You can see the clear shift from the follicular phase to the luteal phase when you look at the chart below. 

TIP: If you are taking your temperature and feel like your temps are all over the place, hold the thermometer in your mouth for at least a minute prior to taking the temp. This warms up the thermometer and helps you get more consistent temps. 


Step 2: Evaluating Current & Past Stressors 

When I talk to clients about healing their hormone imbalances and improving their period symptoms, stress always comes up and can often be a sensitive subject. I'd like to reframe stress a bit before we talk about WHY it matters. 

Hans Selye, the original creator of the term stress and stress researcher, defined stress as ‘the non-specific response of the body to any demand for change.’ Stress is anything that causes our bodies to adapt or change, and it isn't always a bad thing. Stress is how we evolved. What I find is the most important thing when looking at your current, and past stress is looking at how you respond to stress. Do you find you can't handle stress like you used to? Do you have current or past mental/emotional stress contributing to how you respond to stress now?

It's important to get honest with yourself about your current and previous exposure to stress and then look at how you can support your body in handling that stress. I mention previous stressors because many of my clients have reduced and overcome stress in their lives when they come to see me. Just because that stress is gone, doesn't mean your body automatically rebalances. Many of us have been in a compromised state for an extended period, which means we need to focus on steps 3 and 4 the most to regain that balance (homeostasis) in the body that will support healthy hormone production. 

Why Stress Matters

When the body is in a stressed state, there are elevated stress hormones that inhibit certain functions in the body, especially hormone production, since that isn't looked at as essential for survival. Stress also depletes specific vitamins and minerals that are needed for hormone production (magnesium, vitamin C, and sodium, to name a few). 

An Easy Exercise

Pick a day in your calendar and set up some reminders in your phone or via sticky notes that you will easily see to remind you to stop and check-in with yourself throughout the day. The notes can say things like ‘stop and check in’, ‘breathe’, ‘how are you feeling in your body’, etc. 

There's so much noise in our day to day that interferes with our brains getting messages from our bodies on what they need. Personally, I have to set strict boundaries with my phone, email, and social media. Otherwise, I get stressed and feel like I'm pulled in a million directions. Guess what this does? It puts me in fight or flight mode, crushes my appetite, and ruins my productivity. Checking in with myself and building in breaks throughout my day helps me reduce the chatter, tune in, and make sure I'm meeting my needs.


Step 3: Nourishing Your Body

Eating enough food is the only way to give your body the energy it needs to perform the functions required for optimal hormone health. I've talked about compensation in the past and how under eating leads to stress, which causes the body to compensate. This stressed state is no different from what's described above. That's why eating and balancing blood sugar is the number one way to reduce your stress. 

Each of our cells has a tiny engine that requires energy in order to let things inside and out of the cell so it can do its job. When our cells don't get enough energy, all of those engines slow down. This means hormone production, digestion, detoxification, and cognition all slow to a halt. 

I have an entire course specifically on this foundational topic, but here are some basic recommendations for balancing blood sugar that also support eating enough. 

  1. Balance your meals with protein, fat, and carb. Yes it is that simple. It doesn't matter how frequently you eat if you aren't balancing your meals so make sure you start with this step. The amount of fat, carb, and protein depends on your unique needs. I'll be talking about how to use body temp, pulse, and other signs from your body to figure this out in the upcoming course!
  2. Eat every 3-5 hours. If you are in a constant fight or flight state, have low body temperature (less than 97.8F waking), and/or struggle with fatigue, I recommend eating more frequently (closer to the 3 hour mark). If you don't struggle with those issues and have healthy periods, try 4-5. Most of those struggling with hormone problems need 3-4 though. I like to do 3 regular size meals and 1-2 small snacks that are protein and carb.
  3. Avoid eating protein or carbs alone. If the body needs carbohydrates, it will take protein and turn it into carbs via a process called gluconeogenesis. Although this is not an efficient process, the body will still resort to this when necessary. This is why eating protein alone can spike your blood sugar. Eating carbs alone allows them to digest very quickly and leads to a high in blood sugar that will inevitably drop, thus putting you on a blood sugar roller coaster. 


Step 4: Minding Your Micronutrients

Prioritizing eating enough is essential for adequate energy for the body, but we also need certain micronutrients. Micronutrients are nutrients we need in small amounts. Although we do need them in small amounts, they are extremely important for overall health. If we look at the nutrients that make up the backbone of progesterone alone, you can see how important it is to make sure you're eating nutrient dense foods.

Prioritizing Nutrient Dense Foods

Nutrient dense means foods that are not only rich in micronutrients, but also easily absorbed. I mention this because plant based diets have become extremely popular, and while I don't think plants are bad, I don't think it's optimal for our overall health to rely on them for all of our nutrients. 

Plants can appear to be rich in certain minerals, however, we don't absorb 100% of what is in plant food because of the protective mechanisms they have such as phytic acid. Phytic acid binds to minerals in plants, which means we don't absorb it all. Again, I'm not saying plants are bad, but this is why nutrient deficiencies occur on a completely plant based diet. 

Let's talk about vitamins in animals vs. plants:

  • Vitamin A – It is approximately 20 times more bioavailable in animal-based food than plant foods. In fact, plant foods don’t actually have any vitamin A. They have carotenoids which have to be converted to Vitamin A. 80 percent or more of natural vitamin A from animal sources is absorbed, but only three percent or less of carotenoids from plant foods are absorbed.
  • Vitamin B – Animal-based foods are the best source of B Vitamins. Vitamin B12 is exclusively found in animal-based foods.
  • Vitamin C – Plant-based foods are a better source of vitamin C.
  • Vitamin D – Sun is the best option for vitamin D--mushrooms and animal protein can also have small amounts. 
  • Vitamin E – Plant-based foods, such as seeds, have higher concentrations of vitamin E. It’s still found in adequate supply in meat and goat's dairy especially.  
  • Vitamin K – Both plant and animal foods have the K1 version; however, plants don’t have K2 which is vital for human life. K2 also has numerous forms. The essential kind we need is MK-4, which is only in animal food. We can convert some K1 to MK-4 but generally not enough to meet our needs.

I think we need a balance of animal based foods and plant foods in order to meet 100% of our macro and micronutrient needs and allow our bodies to thrive. Here are some of my favorite animal and plant foods to include in a nutrient dense diet:

  • grass fed beef 
  • wild caught seafood 
  • eggs (especially the yolk)
  • organ meats
  • bone broth and gelatin
  • raw carrots 
  • cooked greens 
  • broccoli sprouts
  • coconut in all forms 
  • grass fed butter 
  • grass fed dairy (raw is most optimal)

Remember, although it can be fun to focus on specific micronutrients, if you don't have the previous 3 steps in place, it likely won't move the needle for your hormone health. 

As you can see, progesterone imbalance is complex and has many different areas of focus in order to naturally start improving. Nutrition is number one to begin with. You can join the Nutrition Strategies for Better Periods course to learn how to eat for healthy hormones here.
