Estrogen levels can be increased through hormone therapy, dietary changes, targeted nutrition, and lifestyle adjustments. The right approach depends on why your levels are low in the first place. Premenopausal women typically have estradiol levels between 10 and 300 pg/mL, while postmenopausal women usually fall below 10 pg/mL. If you suspect low estrogen, a simple blood test can confirm where you stand and help guide your next steps.
Why Your Estrogen Might Be Low
Estrogen production shifts throughout life, but certain factors can drive levels down faster or further than expected. Menopause is the most common reason. The ovaries gradually stop producing estrogen, and levels drop sharply in the years surrounding your last period. But menopause isn’t the only cause.
Undereating relative to how much you exercise can suppress the hormonal signals from your brain that tell your ovaries to produce estrogen. This is common in endurance athletes and people with restrictive eating patterns, and it can cause periods to stop entirely. Very low body fat also plays a role, because fat tissue is one of the places your body converts other hormones into estrogen using an enzyme called aromatase. Less fat tissue means less of that conversion happening.
Surgical removal of the ovaries, certain medications, and conditions affecting the pituitary gland can also cause estrogen to drop. Knowing the underlying cause matters because it shapes which strategies will actually work for you.
Hormone Therapy: The Most Direct Option
For women with significantly low estrogen, particularly during or after menopause, prescription hormone therapy is the most effective way to raise levels. It comes in several forms, and choosing between them is largely about convenience, absorption, and insurance coverage.
Patches are one of the most popular options among both patients and providers. Depending on the prescription, they’re applied once or twice a week, which makes them low-maintenance. Oral pills have the longest track record of scientific data and now come in bioidentical formulations that closely match the estrogen your body produces naturally. Topical gels, creams, and sprays are rubbed into the forearm or thigh and offer another option for women who prefer not to swallow a pill or wear a patch.
For women whose symptoms are mainly vaginal (dryness, discomfort, urinary issues), local vaginal products like creams, rings, tablets, or suppositories deliver estrogen directly where it’s needed. Rings are typically replaced every three months, while other vaginal products require daily or twice-weekly use.
One important detail: if you still have a uterus, estrogen therapy alone can thicken the uterine lining and raise the risk of endometrial cancer. That’s why a second hormone, progestin, is prescribed alongside estrogen in those cases. Combined hormone therapy carries a small increased risk of heart attack in older women, particularly those who start it well after menopause or who have existing health conditions.
Most people notice symptoms improving within a few days to a few weeks of starting therapy. For some, it takes several months. If nothing has changed after a few months, your provider can adjust the dose, switch the delivery method, or refer you to a menopause specialist.
Phytoestrogen-Rich Foods
Phytoestrogens are plant compounds that can bind to estrogen receptors in your body and produce mild estrogenic effects. They won’t raise your estradiol levels the way hormone therapy does, but for women with modestly low levels or those looking for dietary support alongside other strategies, they’re worth incorporating.
Soy foods are the richest source. Firm tofu contains about 30 mg of isoflavones per 100 grams (roughly a third of a standard block). Fried tofu is slightly higher at about 35 mg per 100 grams, while silken tofu comes in around 18 mg. A cup of soy milk provides roughly 10 to 11 mg of isoflavones. The key compound in soy, genistein, binds to both types of estrogen receptors in the body, which is why soy has the strongest estrogenic effect among plant foods.
Flaxseeds are often mentioned in this context, but their estrogenic activity comes from a different class of compounds called lignans, not isoflavones. USDA data shows flaxseeds contain almost no isoflavones (less than 0.1 mg per 100 grams). Their estrogenic effect operates through a separate pathway and is milder than soy. Other legumes like chickpeas, lentils, and mung beans also contain smaller amounts of phytoestrogens.
Nutrients That Support Estrogen Levels
Two nutrients stand out for their connection to estrogen metabolism: vitamin D and the trace mineral boron.
Boron appears to slow the breakdown of estradiol in the body rather than increasing production. Research suggests that in amounts achievable through a good diet, boron inhibits enzymes responsible for breaking down estrogen. Clinical studies have found that boron supplementation can raise estradiol levels in women, including postmenopausal women already on hormone therapy. This makes it a potentially useful complement to other approaches. Foods rich in boron include avocados, prunes, raisins, almonds, and chickpeas.
Vitamin D interacts with estrogen metabolism through overlapping enzyme pathways. The same mechanism by which boron preserves estradiol also appears to protect active vitamin D from being broken down too quickly. Maintaining adequate vitamin D levels supports the broader hormonal environment your body needs to use estrogen effectively.
Body Composition and Estrogen
Fat tissue is a significant source of estrogen, especially after menopause when the ovaries are no longer the primary producers. Aromatase, the enzyme in fat cells that converts other hormones into estrogen, becomes more active as body fat increases. Research in the Journal of Clinical Endocrinology & Metabolism found that aromatase levels in fat tissue correlated positively with BMI, body fat percentage, and waist-to-hip ratio.
This creates a practical consideration. If you’re underweight or have very low body fat, gaining some weight can genuinely help restore estrogen production. For athletes or active women who’ve lost their periods, the solution often involves eating more calories relative to energy expenditure rather than exercising less, though both factors matter. Restoring adequate energy availability allows the brain to resume sending the hormonal signals that drive estrogen production.
On the flip side, this relationship isn’t a reason to pursue excess weight gain. Higher aromatase activity in obesity is linked to insulin resistance and metabolic problems. The goal is a healthy, sustainable body composition rather than extremes in either direction.
Herbal Supplements: Limited Evidence
Black cohosh, red clover, dong quai, hops, licorice, and ginger are all marketed for menopausal symptom relief. These botanicals contain phytoestrogenic compounds, and many women report feeling better after taking them. The catch is that clinical trials have consistently shown a placebo effect greater than 50% for menopausal symptom relief, making it difficult to separate genuine benefit from expectation.
Red clover contains genistein, the same active isoflavone found in soy. Black cohosh may work through different mechanisms that aren’t fully understood. Neither has strong enough evidence for major medical organizations to recommend them as reliable alternatives to hormone therapy. If you want to try them, they’re generally considered low-risk for most women, but they shouldn’t be your only strategy if your estrogen is significantly depleted.
Putting It Together
The most effective approach depends on how low your estrogen is and what’s causing the drop. For postmenopausal women with levels below 10 pg/mL and bothersome symptoms, prescription hormone therapy is the most reliable path, with noticeable improvement often starting within weeks. For younger women whose low estrogen stems from undereating or excessive exercise, restoring energy balance can bring levels back naturally without medication.
Dietary phytoestrogens, boron-rich foods, and adequate vitamin D form a reasonable supporting foundation regardless of where you are. A few servings of soy foods weekly, a handful of almonds or prunes, and attention to your vitamin D status won’t replace medical treatment when it’s needed, but they support the hormonal environment your body works within every day.
