Progesterone 101

When it comes to hormones, progesterone doesn’t always get the attention it deserves. Most people know about estrogen and its role in the body, but progesterone is just as important. Whether you’re thinking about starting a family or just trying to feel your best, progesterone is key to keeping your body functioning smoothly.

This hormone does much more than support fertility. It plays a role in your menstrual cycle, your mood, your sleep, and even your energy levels. If your progesterone levels are out of balance, your body lets you know through a range of symptoms. Let’s dive into what progesterone does and how to make sure your levels are where they need to be.

What Is Progesterone?

Progesterone is a hormone produced primarily by your ovaries during the second half of your menstrual cycle, right after ovulation. While it’s most well-known for its role in preparing your uterus for pregnancy, progesterone is important for everyone—regardless of whether you’re trying to conceive or not.

What Does Progesterone Do?

Progesterone plays a variety of roles in keeping your body balanced and healthy.

1. Regulates Your Menstrual Cycle

Progesterone helps ensure a healthy, regular cycle by coordinating estrogen. It supports the thickening of the uterine lining in preparation for a possible pregnancy and signals your body to shed that lining during your period if pregnancy doesn’t occur.

2. Keeps Estrogen in Check

Think of progesterone as estrogen’s counterpart. When these two hormones are in balance, your body thrives. But if progesterone levels drop too low, it can lead to issues like heavy periods, mood swings, and bloating.

3. Supports Your Mood

Progesterone has calming properties because it interacts with GABA, a neurotransmitter that promotes relaxation. This can help reduce anxiety, improve sleep, and stabilize your mood.

4.Improves Sleep

If you’ve ever experienced insomnia before your period, low progesterone might be to blame. Progesterone has a sedative-like effect on the brain, helping you fall asleep more easily and stay asleep longer.

5. Protects Bone Health

Progesterone plays a role in maintaining bone density by stimulating the production of new bone tissue. This becomes especially important as you age and hormone levels fluctuate.


Signs of Low Progesterone

When progesterone levels are low, your body may send you signals like:

  • Irregular or missed periods

  • Spotting between cycles

  • Fatigue or low energy

  • PMS symptoms, like mood swings or bloating

  • Trouble sleeping or feeling anxious

  • Difficulty getting pregnant or maintaining a pregnancy

If these symptoms sound familiar, it may be time to check your hormone levels.


How to Support Healthy Progesterone Levels

The good news is there are natural ways to support your progesterone levels and help bring your body back into balance.

1. Manage Stress

Chronic stress can cause your body to prioritize cortisol (the stress hormone) over progesterone production. Mindfulness practices, yoga, or even a simple deep-breathing exercise can make a difference.

2. Focus on Nutrition

Certain nutrients support hormone production:

  • Magnesium: Found in almonds, spinach, and dark chocolate

  • Zinc: Found in pumpkin seeds, chickpeas, and seafood

  • Vitamin B6:Found in bananas, salmon, and sweet potatoes, Vitamin B6 plays a crucial role in hormone regulation. Adding these foods to your meals can help support healthy progesterone levels.

3. Prioritize Sleep

Sleep is when your body does its best work in coordinating hormones. Aim for 7–9 hours of quality sleep per night and try to stick to a consistent bedtime routine. Reducing screen time before bed and creating a calming environment can also help.

4. Monitor Your Hormones

Understanding your hormone levels is an important first step. Tools like Eli’s Hormometer™ can give you real-time insights into your progesterone levels, helping you identify patterns and make informed decisions about your health.
