What You Need To Know About Estrogen

There's a lot of noise around estrogen right now. Depending on where you land on the internet, you might walk away thinking it's something to fear, something to "detox," or something that's making everything worse. And honestly? We think that narrative is doing more harm than good.

Because, spoiler alert, estrogen isn’t the villain. In fact, it's one of the most important hormones in your body, and understanding what it does (and what happens when it's dysregulated) is one of the most empowering things you can do for your health! Let's clear the air.

What does estrogen do?

Most people associate estrogen with reproduction—which is totally fair. After all, it plays a central role in your menstrual cycle, helping to build the uterine lining each month and triggering ovulation. But its job description is so much bigger than that.

Estrogen influences your brain, your bones, your heart, your skin, your mood, and your metabolism. It supports serotonin production, which is a big part of why you might feel sharper and more emotionally steady during the first half of your cycle when estrogen is naturally rising. It helps maintain bone density by supporting the process of replacing old bone tissue with new, healthy tissue. It plays a protective role in cardiovascular health by supporting healthy cholesterol levels. It even affects how your body stores and uses energy.

In short: estrogen isn't just a "reproductive hormone." It's a whole-body hormone. And when it's in balance, you feel it in almost every area of your life.

Common misconceptions about estrogen

Let's address a few of the big ones, because these tend to cause unnecessary fear and confusion.

Misconception #1: Estrogen is always the problem.

This is probably the most widespread one. A lot of wellness content frames estrogen as something that's always "too high" or always needs to be lowered. But estrogen being too low is just as common and just as disruptive. The goal isn't to minimize estrogen. It's to support balance between estrogen and progesterone so they can do their jobs effectively. 

Misconception #2: You need to "detox" your estrogen.

Your body already has a system for metabolizing and eliminating estrogen. It happens primarily through your liver and your gut. What your body actually needs is support for those pathways (through fiber, adequate nutrition, and a well-functioning digestive system), not a restrictive protocol designed to flush estrogen out.

Misconception #3: High estrogen and estrogen dominance are the same thing.

They're not. Estrogen dominance doesn't necessarily mean your estrogen is high. It means estrogen is high relative to progesterone. You can have completely normal estrogen levels and still experience estrogen dominance if your progesterone is too low. This distinction matters because the approach to addressing it looks different depending on what's actually going on. 

How to know if your estrogen is too high or too low

This is where body literacy becomes incredibly valuable! Your body gives you signals, and once you know what to look for, those signals start to make a lot more sense.

Signs your estrogen may be elevated (or unopposed by progesterone):

• Heavy or prolonged periods
• Breast tenderness or swelling (especially before your period)
• Bloating that feels cyclical
• Mood swings or heightened irritability
• Weight gain (particularly around the hips and thighs)
• Headaches or migraines that seem to track with your cycle
• Brain fog
• Fatigue, even when you're sleeping enough

Signs your estrogen may be too low:

• Irregular or missed periods
• Hot flashes or night sweats (even outside of menopause)
• Vaginal dryness
• Joint pain or stiffness
• Difficulty concentrating
• Low mood or increased anxiety
• Dry skin
• A noticeable drop in energy or motivation.

Low estrogen is especially common in women who are underfueling, overtraining, postpartum, or approaching perimenopause.

The important thing to remember is that estrogen doesn't exist in isolation. It works in relationship with progesterone, cortisol, thyroid hormones, and insulin. That's why looking at the full picture (rather than trying to fix one hormone in a vacuum) matters so much!

What influences your estrogen levels?

A lot of things, honestly. And most of them come back to how well your body is being supported on a daily basis. Chronic stress is a big one. When your body is constantly producing cortisol, it can interfere with ovulation, which disrupts the natural rise and fall of both estrogen and progesterone. Under-eating or restricting fats and cholesterol can also have a direct impact, because your body literally needs dietary fat and cholesterol to produce steroid hormones (estrogen included).

Poor gut health plays a role too. Your gut is responsible for eliminating used estrogen, and when that process is sluggish, estrogen can get recirculated back into the bloodstream instead of being cleared out. Environmental factors like endocrine disruptors in plastics, personal care products, and pesticides can also mimic estrogen in the body, adding to the overall load.

 Nutrients that support healthy estrogen balance

Fortunately, supporting estrogen balance doesn't have to be complicated. It starts with consistent, well-rounded nutrition and a few key nutrients that help your body do what it's already designed to do.

1. Fiber is foundational. It supports healthy digestion and helps your body eliminate metabolized estrogen through the gut. Vegetables, fruits, legumes, and seeds are all excellent sources. Cruciferous vegetables (broccoli, cauliflower, Brussels sprouts, cabbage) contain compounds called glucosinolates that support estrogen metabolism in the liver, helping your body process estrogen more efficiently.
2. B vitamins, particularly B6 and folate, play a role in hormone metabolism and methylation, which is one of the key pathways your liver uses to break down estrogen. You'll find these in leafy greens, poultry, eggs, and legumes.
3. Magnesium supports your nervous system and stress response, both of which have a downstream effect on hormone balance. It also plays a role in estrogen detoxification. Dark chocolate, pumpkin seeds, and leafy greens are great sources (and our magnesium powder is an easy way to stay consistent here).
4. Omega-3 fatty acids help manage inflammation, which can affect how your body produces and responds to hormones. Fatty fish, walnuts, and flaxseeds are all solid options. 
5. And just like with progesterone, the foundation matters: eating enough (getting adequate protein and fiber) and not skipping meals. Your body won't prioritize hormone production if it doesn't feel like it has the resources to do so.

Where seed cycling fits in

This is one of the reasons seed cycling can be such a great tool for supporting estrogen. During the follicular phase (days 1-14), flax and pumpkin seeds provide lignans and zinc that help support healthy estrogen production and metabolism. Flaxseeds contain phytoestrogens called lignans, which have a unique ability to support estrogen modulation. Some experts say that when estrogen is low, they can have a mild estrogen-like effect. When estrogen is elevated, they can help bind to estrogen receptors and reduce its overall impact. Of course, if you’re dealing with estrogen-driven diseases, always work with your practitioner before introducing new routines, products, or supplements. 

During the luteal phase (days 15-28), sesame and sunflower seeds step in. Sesame seeds are rich in lignans and zinc, which help support progesterone production and keep estrogen from going unopposed. Sunflower seeds provide vitamin E and selenium, both of which support progesterone and help your liver process excess estrogen.

The bigger picture

When estrogen is out of balance (whether too high, too low, or unopposed), your body will tell you. The key is learning to listen. Fortunately, you don't need to overhaul everything at once. Start by eating enough. Make sure you're getting adequate fiber, fat, and protein. Add in a few of the key nutrients we talked about. Support your gut and your stress response. And if you want a simple daily habit that aligns with your cycle, seed cycling is a great place to begin.
