Can Phytoestrogens Help With Hot Flashes?

Key Takeaways:

  • Phytoestrogens are plant-based compounds that mimic estrogen in the body.
  • Phytoestrogens can be effective in reducing the frequency and intensity of hot flashes in menopausal women.

If you’re a woman in your late forties or early fifties, you may be experiencing symptoms of menopause or perimenopause. Although it is a natural stage of life, hot flashes, joint discomfort, dry skin, and mood changes can make you desperate for relief.

Phytoestrogens are compounds that naturally occur in plants, and have been known to support common signs of menopause. Let’s take a closer look at what the science says about phytoestrogens and menopause.



What are phytoestrogens?

Phytoestrogens are plant-based compounds that mimic estrogen in the body. “Phyto-” is a Greek word meaning “plant” and estrogen is a female hormone that regulates functions in both women and men. There are four main groups of phytoestrogens: isoflavonoids, flavonoids, stilbenes, and lignans.1 Flavonoids and lignans are the most commonly occurring.


Phytoestrogen vs. estrogen

Because phytoestrogens and estrogen have a similar chemical structure, when you eat phytoestrogens your body may respond as if estrogen is present.

According to a study published in Endocrinology, phytoestrogens can attach to estrogen receptors in your cells, potentially affecting the function of estrogen throughout the body.2 However, not all phytoestrogens function the same way.

Phytoestrogens have been shown to have both estrogenic and antiestrogenic effects. This means that there are mixed results: while some phytoestrogens have estrogen-like effects and increase estrogen levels in your body, others block its effects and decrease estrogen levels.3

Phytoestrogens are complicated, to say the least, which makes them a controversial topic in nutrition science.


Phytoestrogen-rich foods

Some foods, like fruits, veggies, legumes, and some grains, contain phytoestrogens. However, some foods contain higher levels of phytoestrogens than others.

Can phytoestrogens help with signs of menopause?

Menopause is the end of a woman’s reproductive cycle and is defined as twelve complete months without menstrual bleeding.

During menopause, the body goes through major hormonal changes, decreasing the amount of hormones it makes – mainly estrogen and progesterone. When this decrease in estrogen occurs, the menstrual cycle (period) starts to change or become irregular before it eventually stops.

This decrease in estrogen also triggers the uncomfortable symptoms of hot flashes, night sweats, sleep disturbances, and vaginal dryness. Scientists are very interested in the use of phytoestrogens to treat common menopausal symptoms.

Overall, the research shows that phytoestrogens are effective in reducing the frequency and intensity of hot flashes in menopausal women.4 According to one study, certain phytoestrogens have also been shown to decrease vaginal atrophy, improve sleep and cognition, and positively affect bone health.5

Did you know?

Part of the reason scientists are interested in phytoestrogens for menopause is because typical menopausal symptoms are much less frequently experienced by Asian women than by women in America or Europe, which may be in part due to typical, traditional Asian diets being rich in phytoestrogens.6 7

Other ways to deal with common signs of menopause

1. Care for your dry skin

Menopause can bring noticeable changes to your skin. Once your estrogen levels begin to decline, your body’s ability to produce oil slows down, leaving the skin dry and itchy.

Here are some easy ways to treat dry, itchy skin:

  • Wear sunscreen every day: apply SPF 30 or higher each day to help protect the skin from harmful UV rays.
  • Lotion up: apply a moisturizer at least twice a day to help lock in the hydration.
Take a skincare supplement

2. Avoid hot flash triggers

Hot flashes are one of the most common symptoms of menopause and can sometimes last for years.

If hot flashes or night sweats keep you up at night, try drinking small amounts of cold water before bed, layering your bed sheets, or keeping your room at a cooler temperature.

Try avoiding alcohol, spicy foods, and caffeine, as these may trigger hot flashes or make them worse. Women who smoke have also been found to be 1.6x more likely to experience hot flashes than women who don’t smoke, so quitting smoking is the best option for all areas of your health – including menopause.8

3. Prioritize your mental health

The years surrounding menopause bring many changes to your body, but they can also make an impact on your mind as well – especially your mental health. Women who have struggled with anxiety in the past may see a resurgence of symptoms.9

When dealing with the mental health effects of menopause:

  • Reach out to others: don’t struggle alone.
  • Make lifestyle changes that support a positive mood, such as getting adequate sleep, exercising regularly, and controlling stress.
  • Monitor your mood, and reach out to a professional if you feel like you need additional help.

4. Take a phytoestrogen supplement

Besides eating phytoestrogen-rich foods, taking a phytoestrogen supplement is another great way to support your estrogen levels during menopause.

Solgar Women’s Balancing Formula includes Thai Kudzu extract (Pueraria mirifica), which grows only in two provinces in Thailand, has a long history of traditional use for promoting vitality.†* Modern research has discovered that this particular species of Thai Kudzu contains a complex of phytoestrogens, including miroestrol.
