Women can lower elevated testosterone through a combination of dietary changes, medications, and lifestyle shifts that target the hormonal pathways driving overproduction. Normal testosterone for adult women falls below 40 ng/dL, and levels above that range often cause noticeable symptoms like excess facial or body hair, acne, thinning scalp hair, and irregular periods. The most effective approach depends on what’s causing the elevation in the first place.
Why Testosterone Gets Too High
The most common reason women develop high testosterone is polycystic ovary syndrome (PCOS), which affects roughly 1 in 10 women of reproductive age. But the deeper driver in many cases is insulin resistance. When your body produces too much insulin to compensate for cells that aren’t responding well to it, that excess insulin directly stimulates the ovaries and adrenal glands to pump out more androgens, including testosterone. This happens because the ovaries remain sensitive to insulin’s growth-signaling effects even when the rest of the body has become resistant to its blood sugar effects.
Specifically, high insulin amplifies the effect of luteinizing hormone (LH) on the ovarian cells that produce androgens. It also suppresses production of a protein called SHBG in the liver. SHBG acts like a sponge that soaks up testosterone in your bloodstream and makes it inactive. When SHBG drops, more testosterone circulates freely and actively binds to receptors in your skin, hair follicles, and other tissues. This is why two women with identical total testosterone numbers can have very different symptoms: what matters most is how much of it is “free” and unbound.
Dietary Changes That Make a Real Difference
Because insulin is so central to the problem, eating in a way that keeps blood sugar stable is one of the most impactful things you can do. A study on overweight women following a low-glycemic diet for 60 days found significant decreases in total testosterone and the free androgen index, along with a meaningful increase in SHBG. In practical terms, a low-glycemic diet means choosing foods that release glucose slowly: whole grains over refined ones, legumes, non-starchy vegetables, nuts, and protein paired with carbohydrates rather than carbs eaten alone.
You don’t need to follow a rigid meal plan. The core principle is reducing blood sugar spikes, which in turn reduces the insulin surges that tell your ovaries to make more testosterone. Swapping white bread for sourdough, choosing steel-cut oats over instant, eating fruit with a handful of almonds, and building meals around protein and fiber all move the needle. A slight calorie deficit, if you carry extra weight, adds to the effect since fat tissue itself contributes to insulin resistance and androgen production.
Omega-3 Fatty Acids
A randomized trial in overweight women with PCOS found that taking 3 grams of omega-3s daily for eight weeks significantly lowered testosterone concentrations compared to placebo. The effect was specific to total testosterone and didn’t change SHBG or the free androgen index, so omega-3s likely work through a different mechanism than dietary changes alone. Good food sources include fatty fish (salmon, sardines, mackerel), walnuts, and flaxseed, though reaching 3 grams daily typically requires a supplement.
Spearmint Tea
Spearmint has mild anti-androgenic properties and is one of the few herbal options with clinical data behind it. In a Turkish study, women with excess hair growth who drank one cup of spearmint tea twice daily for five days saw significant drops in free testosterone. A follow-up randomized trial extended this to 30 days of twice-daily spearmint tea and confirmed reductions in androgens compared to a chamomile tea control group. Total testosterone and DHEAS (an adrenal androgen) weren’t significantly affected, suggesting spearmint works by freeing up SHBG or altering how testosterone is metabolized rather than stopping production outright.
Two cups of spearmint tea a day is safe for most people and easy to maintain. It won’t produce dramatic results on its own, but it’s a reasonable addition to other strategies.
Inositol Supplements
Myo-inositol is a naturally occurring compound that improves how your cells respond to insulin. In a meta-analysis of randomized controlled trials in women with PCOS, daily doses of 1.1 to 4 grams taken for 12 to 24 weeks showed a trend toward reduced testosterone, though the effect didn’t quite reach statistical significance across all studies. Where inositol shows stronger and more consistent results is in improving ovulation and menstrual regularity, which are often the symptoms women care about most. The typical dose used in research is 4 grams per day, usually split into two doses.
Prescription Medications
When lifestyle changes aren’t enough, several medications can bring testosterone down more aggressively.
Combined Birth Control Pills
Oral contraceptives are the most commonly prescribed first-line treatment. They work through two mechanisms at once: the estrogen component stimulates the liver to produce more SHBG, which binds and deactivates circulating testosterone, while both the estrogen and progestin components suppress the ovarian signals that drive androgen production. A systematic review and meta-analysis confirmed that free testosterone drops roughly twice as much as total testosterone during pill use, because the SHBG increase is so pronounced. Higher estrogen doses produce greater SHBG increases, though even standard-dose pills are effective.
Spironolactone
Spironolactone is an androgen blocker originally developed as a blood pressure medication. At doses of 100 to 200 mg daily, it decreases the rate of testosterone production and increases how quickly the body clears it. It also blocks testosterone from binding to receptors in the skin and hair follicles, which makes it particularly useful for acne and unwanted hair growth. Spironolactone is almost always prescribed alongside birth control because it can cause irregular bleeding on its own and poses risks during pregnancy.
Metformin
Metformin targets the insulin resistance piece directly. By improving how your body uses insulin, it removes the signal that’s pushing the ovaries to overproduce testosterone. In a long-term follow-up study of overweight women with PCOS, testosterone dropped about 15% in the first year and continued declining to roughly 25 to 40% below starting levels by the fifth year. This slow, progressive improvement reflects the fact that metformin is addressing the metabolic root cause rather than just masking hormone levels. It’s often used alongside other treatments or as an alternative for women who can’t take hormonal contraceptives.
Exercise and Body Composition
Regular physical activity lowers testosterone in women primarily by improving insulin sensitivity. Both aerobic exercise and resistance training help, and the combination appears to be more effective than either alone. You don’t need extreme routines. Consistent moderate activity, something like 150 minutes of brisk walking or cycling per week plus two strength sessions, is enough to meaningfully shift insulin dynamics over a few months.
Losing even a modest amount of weight, around 5 to 10% of body weight if you’re carrying excess, can produce measurable drops in testosterone and improvements in SHBG. Fat tissue is metabolically active and contributes to both insulin resistance and androgen production, so reducing it addresses both pathways simultaneously.
How Long Results Take
This is where many women get frustrated. Blood levels of testosterone can start shifting within a few weeks of starting medication or making dietary changes, but the symptoms you actually see in the mirror respond much more slowly. Acne typically takes three to six months of consistent treatment to clear significantly. Excess hair growth is the slowest to respond because hair follicles cycle over months. You may need six to twelve months before you notice reduced growth, and existing hair won’t fall out on its own, so many women combine hormonal treatment with hair removal methods like laser or electrolysis.
Menstrual regularity often improves within the first two to three months of treatment, making it one of the earliest signs that your approach is working. If your cycles become more predictable, that’s a good signal that testosterone and insulin are moving in the right direction even before you see changes in skin or hair.
Combining Approaches for the Best Outcome
No single intervention works as well alone as a combination does. The most effective strategy for most women pairs a low-glycemic diet and regular exercise with one or two targeted treatments. For someone with PCOS and insulin resistance, that might look like dietary changes plus metformin or inositol to address the metabolic root, combined with a birth control pill or spironolactone to manage symptoms while the slower metabolic improvements take hold. Adding spearmint tea or omega-3s on top of that is low-risk and potentially additive.
The key insight is that testosterone elevation in women is rarely a standalone hormone problem. It’s almost always downstream of insulin dynamics, body composition, or ovarian signaling patterns. Treatments that address those upstream causes produce more durable results than those that only block the hormone at the end of the chain.
