13+ Supplements to Reduce Estrogen Dominance

This is the time when your body starts making the transition towards menopause.

As ovulation starts to slow down, your progesterone levels drop. Without enough progesterone to keep it in check, estrogen becomes the dominant hormone. 

See my related articles on how to reduce bloating during perimenopause and best supplements and natural treatments for menopause joint pain.

Estrogen dominance can be triggered by too much exposure to estrogen through either our diets or our environments (known as exogenous estrogens).

Foods like flax, soy, and many other plant-based foods are high in phytoestrogens – natural compounds that can behave like the estrogen in our bodies. Eating too many of these foods may raise overall estrogen levels. 

Similarly, xenoestrogens – manmade compounds found in many plastics, household products, cosmetics, and other chemicals – also mimic the natural estrogens in our body and cause estrogen dominance.

Your body needs just the right amount of estrogen-metabolizing bacteria in your gut to keep your estrogen levels where they should be. These bacteria – known as estrobolome – regulate whether or not estrogen is excreted from the body. 

Try eating 1-2 raw carrots a day to help improve your gut diversity and help with healthy estrogen metabolism. Or, try my Raw Carrot Salad to help reduce estrogen dominance symptoms.

Certain medications can trigger a rise in estrogen levels, including some antibiotics, phenothiazines (used to treat certain mental health conditions), hormone replacement therapy, contraceptives, and some herbal remedies. High estrogen can also run in families.

Now that we’ve covered the role of estrogens in female body and how estrogen dominance can occur and its symptoms, let’s discuss some of the supplements that can help.

As always, please consult your healthcare provider before making any changes to your supplement routine. Some of these supplements are very powerful so you really should discuss them with your healthcare provider before taking them.

DIM (diindolylmethane) is a plant nutrient found in cruciferous vegetables like broccoli, cabbage, cauliflower, and Brussels sprouts.

DIM isn’t itself a hormone or type of estrogen, but it has a similar structure. When consumed, it aids with the production of “good” estrogen while lowering the production of “bad”, creating a harmonious balance.

To get the full benefit of DIM from cruciferous vegetables, you would need to eat quite a lot every day – around 2 pounds, in fact. A DIM supplement makes it easier to get enough of this nutrient on a daily basis.

You can also try growing and eating broccoli sprouts or broccoli microgreens to help increase your DIM intake.

Progesterone has a mitigating effect on estrogen, so increasing its production is a good way to counter the effects of estrogen dominance.

Vitamin B6 is essential for the production of progesterone and also helps the liver metabolize and break down estrogen, keeping your hormonal levels balanced. In this way, B vitamins can help with liver function.

What’s more, vitamin B6 helps improve your mood and reduce anxiety, making it helpful in dealing with the symptoms of estrogen dominance.

Probiotics are made up of a mixture of live, helpful bacteria and/or yeasts just like those that already live naturally in your body. They promote gut health by restoring a healthy balance of “good” bacteria which then break down excess estrogen so that it can be excreted from your body.

Because the microbes used as probiotics are already present in your body, they are considered safe for most people to take. You can also eat more foods with natural probiotics to help increase your levels.

Omega-3 fatty acids are anti-inflammatory and are useful for supporting the production of hormones. They are known as essential fatty acids because they are important for your health but are not made by your body.

This means it is important to get them from foods – like oily fish, walnuts, flax seeds, and leafy green vegetables – or from supplements.

Calcium D-glucarate is a calcium salt that combines calcium with glucaric acid, a natural chemical that is found in our bodies and also in some foods.

Studies have shown that calcium D-glucarate helps your body eliminate excess estrogen and prevents it from being reabsorbed. It does this by slowing down the action of an enzyme that we produce in our gut called beta-glucuronidase.

When our gut health is poor, we produce too much beta-glucuronidase, which in turn stops our liver from properly detoxifying our blood. Calcium D-glucarate counteracts this effect, stabilizing our estrogen levels.

Milk thistle – also known as holy thistle and Mary thistle – is a flowering herb that has traditionally been used to treat liver and gallbladder disorders. It contains an antioxidant compound called silymarin, which is believed to stop toxins from attaching themselves to the cells in your liver.

Since liver health is fundamental to the regulation of estrogen, taking milk thistle should help keep your hormones balanced.

An incredibly important mineral, magnesium is involved in hundreds of chemical reactions throughout the body, many of which affect your hormonal balance.

Magnesium supports your liver in detoxification so that excess estrogen is eliminated from your body. It also plays a part in the manufacture of both progesterone and estrogen – helping keep things balanced – and is good for the digestive system too.

It’s not always easy to get as much magnesium as we need from food alone, so a supplement is a good option for your overall health.

See my full article about the different types of magnesium.

Despite its name, vitamin D is actually a hormone rather than a vitamin. In addition to supporting the immune system, optimal levels of vitamin D have been shown to lower estrogen levels in women with estrogen dominance. 

It’s important to have your vitamin D levels tested at least several times a year! See my other recommendations for lab tests for women.

Turmeric is packed with antioxidant compounds, and perhaps the most interesting one is curcumin. Not only has it been found to have anti-inflammatory properties, but it can also support liver detoxification – both useful elements in keeping your hormones balanced.

The curcumin from turmeric is not easily absorbed and in order to see real benefits, you need more than you can get from cooking with it. This is when supplementary turmeric can be very useful.

Resveratrol – a plant compound that acts like an antioxidant – helps with estrogen dominance in two ways.

First, it supports detoxification in the liver – thereby preventing excess estrogen from accumulating. Secondly, it is an “anti-aromatase” compound, which means that it helps stops the aromatase enzyme in your body from converting testosterone to estrogen. This helps keep your estrogen levels lower.  

Zinc has anti-inflammatory properties and is also known to stimulate the pituitary gland to release FSH (follicle-stimulating hormone). This in turn promotes ovulation, which then increases your levels of progesterone, bringing your hormones into balance.  

Like resveratrol, selenium keeps down aromatase levels in the body, preventing the conversion of testosterone to estrogen. It also helps support the breakdown of estrogen in the liver.

Taurine is an amino acid, present in some animal foods but completely absent form plant foods.

It is an important factor in controlling estrogen levels because it helps support the formation of bile acids in the liver. This prevents gallstones and ensures that the liver is detoxifying estrogen as it should, rather than allowing levels to accumulate and result in high estrogen levels.
