Estrogen levels can be increased through hormone therapy, dietary changes, lifestyle adjustments, and certain supplements, depending on why levels are low in the first place. The right approach varies significantly based on whether you’re dealing with menopause, a medical condition like primary ovarian insufficiency, or lifestyle factors that have suppressed your natural production. Understanding your starting point matters, because normal estradiol (the most active form of estrogen) ranges from 20 to 350 pg/mL during the first half of a menstrual cycle, drops as low as 15 pg/mL after a period, and can fall below 5 pg/mL after menopause.
Why Your Estrogen Might Be Low
The ovaries produce most of a premenopausal woman’s estrogen, so anything that disrupts ovarian function can cause levels to drop. Menopause is the most common reason, but it’s far from the only one. Extreme dieting, excessive exercise, very low body fat, chronic stress, and certain medications can all suppress estrogen production in younger women. Primary ovarian insufficiency, where the ovaries stop working normally before age 40, is another cause.
Body fat plays a direct role in estrogen production. Adipose tissue contains an enzyme called aromatase that converts other hormones into estrogen. Women who are significantly underweight may produce less estrogen through this pathway, while those with higher body fat tend to produce more. This is one reason why very lean athletes sometimes lose their periods.
Hormone Therapy: The Most Direct Option
For women experiencing menopause or other medical causes of low estrogen, prescription hormone therapy is the most effective way to raise levels. It comes in several forms: pills, skin patches, gels, creams, and vaginal preparations. Patches, for example, are typically applied twice a week to the lower abdomen or buttocks, with application sites rotated to avoid skin irritation. The starting dose for managing hot flashes is generally higher than the dose used for bone loss prevention.
The Menopause Society considers hormone therapy first-line treatment for bothersome hot flashes, genitourinary symptoms (vaginal dryness, urinary issues), primary ovarian insufficiency, and bone loss prevention. Benefits typically outweigh risks for healthy women who start before age 60 or within 10 years of menopause onset. That said, hormone therapy is not recommended for preventing heart disease, dementia, or general aging in women who go through menopause at the typical age.
The type of hormone therapy matters for risk. Estrogen-only therapy (used by women who’ve had a hysterectomy) is actually associated with a 14% reduction in breast cancer incidence compared to never using hormones. Combination therapy with estrogen plus a progestin carries a different profile: women using it for more than two years have an 18% higher rate of breast cancer compared to non-users. In absolute terms, that translates to roughly a 4.5% cumulative risk of breast cancer before age 55, compared to 4.1% for women who never used hormones.
Compounded “Bioidentical” Hormones
You’ve likely seen marketing for compounded bioidentical hormones, often framed as more natural or safer than standard prescriptions. The reality is more complicated. These custom-mixed preparations are not reviewed by the FDA for safety, effectiveness, or quality. Independent testing has confirmed that the amount of active hormone in compounded products can vary significantly from dose to dose. There are also no requirements for adverse event reporting, which makes it difficult to assess long-term safety.
The American College of Obstetricians and Gynecologists notes that many FDA-approved hormone therapy products already contain bioidentical hormones (chemically identical to what your body makes), so the term “bioidentical” doesn’t distinguish compounded products in any meaningful way. Short-term studies haven’t found major safety red flags with compounded formulations, but data are inadequate to assess risks of breast cancer, endometrial cancer, or cardiovascular disease. If you’re considering hormone therapy, FDA-approved options offer more predictable dosing and better-studied safety profiles.
Foods That Contain Plant Estrogens
Phytoestrogens are plant compounds that weakly mimic estrogen in the body. They’re not a substitute for hormone therapy, but they may offer modest hormonal support. Soy products are by far the richest dietary source. Raw soybeans contain about 155 mg of isoflavones per 100 grams, soy flour around 150 to 178 mg, and tempeh about 61 mg. More everyday portions look like this: tofu has roughly 30 mg per 100 grams, miso about 41 mg, and a cup of soy milk around 11 mg per 100 grams.
Despite what you may read online, most other foods contain negligible amounts of isoflavones. Flaxseeds contain a different type of phytoestrogen (lignans, not isoflavones), with their isoflavone content registering at just 0.07 mg per 100 grams. Chickpeas, split peas, and other legumes all come in under 0.5 mg per 100 grams. If you’re trying to get meaningful phytoestrogen intake from food, soy products are really the only significant source.
The practical impact of eating soy is modest. Some women report mild improvement in hot flashes and other menopausal symptoms, but the effects are far less dramatic than hormone therapy. Think of phytoestrogen-rich foods as a gentle nudge, not a replacement for medical treatment when estrogen is significantly low.
Herbal Supplements: What the Evidence Shows
Black cohosh and red clover are the two most commonly marketed herbal supplements for menopausal symptoms. Both have been studied in clinical trials, and the results are underwhelming. A well-designed phase II trial at the University of Illinois at Chicago failed to show significant reduction in hot flashes for either supplement. The broader research literature doesn’t demonstrate strong support for a beneficial effect of either one on menopausal vasomotor symptoms.
This doesn’t mean no woman has ever felt better taking these supplements, but placebo effects are strong in menopause research, and the clinical evidence doesn’t back the marketing claims. If you choose to try them, keep expectations realistic.
Micronutrients That Support Estrogen Levels
Boron is a trace mineral that appears to influence estrogen metabolism. A USDA study on perimenopausal women found that boron supplementation increased active forms of estrogen in the blood, along with effects on thyroid hormone and markers related to bone health. The researchers concluded that boron affects hormonal processes at the cellular level. Good food sources include avocados, nuts, dried fruits, and legumes. Most people get some boron through diet, but supplementation may help if intake is low.
Vitamin D also plays a role in hormonal health more broadly, and deficiency is common in women with low estrogen. While the direct relationship between vitamin D and estrogen production is complex, maintaining adequate vitamin D levels supports the bone health that estrogen protects, making it a practical complement to other strategies.
Lifestyle Changes That Help
Several lifestyle factors directly influence your body’s estrogen production. Maintaining a healthy body weight is one of the most impactful. Because aromatase in fat tissue converts androgens into estrogen, being significantly underweight can reduce this conversion. Women who have lost their periods due to low body fat or excessive exercise often see cycles return when they gain weight and reduce training intensity.
Chronic stress raises cortisol, which can interfere with the hormonal signaling that drives estrogen production. Sleep deprivation has similar effects. Neither stress reduction nor better sleep will dramatically raise estrogen levels in a postmenopausal woman, but for premenopausal women whose levels are suppressed by lifestyle factors, these changes can make a real difference.
Moderate exercise supports healthy hormone balance, but there’s a tipping point. Intense endurance training without adequate calorie intake is one of the most common causes of low estrogen in younger women. If you’re exercising heavily and noticing missed periods, that’s a sign your body may not be producing enough estrogen, and pulling back on training volume while increasing calorie intake is the most effective intervention.
How to Know If Your Approach Is Working
Symptom improvement is the most practical gauge. If hot flashes decrease, vaginal dryness improves, sleep gets better, or your mood stabilizes, your estrogen levels are likely moving in the right direction. For a more precise measure, a blood test for estradiol can confirm where you stand. Levels fluctuate throughout the menstrual cycle, so timing matters for premenopausal women. Post-menopausal women have more stable (and much lower) levels, making testing more straightforward.
Keep in mind that the goal isn’t to maximize estrogen. It’s to reach a level where symptoms resolve and health risks (particularly bone loss) are managed. For women on hormone therapy, this often means using the lowest effective dose for the shortest duration that meets your needs, then reassessing periodically.
