Are There Any Natural Supplements For Hirsutism? - Women's Health and Harmony
1. Inositol (Myo- and D-Chiro)
Inositol, available in two forms - myo-inositol and D-chiro-inositol - has shown promise in addressing hormonal imbalances that contribute to unwanted hair growth.
How It Works
Inositol plays a key role in improving the body’s sensitivity to insulin, which helps reduce hyperinsulinemia and the associated rise in androgens. Specifically, myo-inositol promotes glucose uptake by aiding in GLUT4 translocation and curbing the release of free fatty acids. By enhancing insulin sensitivity, inositol reduces circulating insulin levels, which in turn lowers androgen production.
Beyond this, inositol supports hormonal balance through two additional mechanisms:
- It improves dominant follicle selection, boosting aromatase activity to decrease androgen levels.
- It encourages the liver to produce more Sex Hormone-Binding Globulin (SHBG), a protein that binds to testosterone, reducing its activity in the body.
These actions explain the improvements seen in androgen profiles among users.
Benefits for Managing Hirsutism
Research highlights inositol’s effectiveness in reducing androgen levels in women with PCOS. A 2023 systematic review and meta-analysis of 26 randomized controlled trials (involving 1,691 women) reported significant reductions in key androgen markers, including:
- Total testosterone: Decreased by 20.39 ng/dL
- Free testosterone: Reduced by 0.41 ng/dL
- Androstenedione: Lowered by 0.69 ng/mL
- SHBG levels: Increased by 32.06 nmol/L
"Inositol is an effective and safe treatment in PCOS. Moreover, inositols showed non-inferiority in most outcomes compared to the gold standard treatment; metformin."
Additionally, one study found that myo-inositol significantly reduced hair growth in about one-third of women with hirsutism, tackling the hormonal root cause.
Recommended Dosage
For optimal results, use a combination of myo-inositol and D-chiro-inositol in a 40:1 ratio, with a daily total of 4,000 mg of myo-inositol and 100 mg of D-chiro-inositol, split into two doses. It’s best to take these doses either right before meals or shortly after your first and last meals of the day. While hormonal improvements might appear within 12 to 24 weeks, noticeable reductions in hair growth may take up to six months of consistent use.
Possible Side Effects
Inositol is generally well tolerated, with only 7% of users reporting mild gastrointestinal symptoms like bloating, nausea, or diarrhea - far fewer than the 53% experiencing similar issues with metformin. These side effects are rare and often dose-dependent.
It’s important to avoid taking high doses of D-chiro-inositol alone, as this can lower estrogen levels and potentially worsen hirsutism. For individuals with diabetes, inositol may amplify the effects of diabetes medications, so blood sugar levels should be closely monitored. Always consult your healthcare provider before starting inositol, especially if you have existing health conditions or are taking other medications.
2. Zinc
Zinc plays a key role in regulating hormones and may help reduce unwanted hair growth in women with PCOS. Many individuals with PCOS have an increased need for zinc, making supplementation an effective way to address hirsutism.
Primary Mechanism
Zinc works by inhibiting the enzyme responsible for converting testosterone into dihydrotestosterone (DHT). DHT is a potent androgen that contributes to excessive hair growth, and this mechanism explains the improvements seen with zinc supplementation.
Benefits for Hirsutism
In a randomized, placebo-controlled trial involving 48 women with PCOS, participants taking 50 mg of elemental zinc daily for 8 weeks showed a significant reduction in hirsutism. The study also highlighted improvements in hair loss, with 41.7% of women experiencing noticeable benefits compared to just 12.5% in the placebo group.
"Using 50 mg/day elemental zinc for 8 weeks among PCOS women had beneficial effects on alopecia, hirsutism." - Jamilian M, et al.
Another study demonstrated that even smaller doses could be effective when combined with other nutrients. Women who took 4 mg of zinc twice daily (8 mg total) along with magnesium, calcium, and vitamin D saw greater reductions in hirsutism over a 12-week period.
Dosage Recommendations
The recommended dietary allowance (RDA) for adult women is 6.8–8 mg of zinc per day. However, studies suggest that higher doses, ranging from 25 to 50 mg daily, are more effective in addressing PCOS-related hirsutism. The most commonly studied dosage is 50 mg per day, which has shown significant results in just eight weeks. Moderate doses, such as 15 to 30 mg daily, may also provide benefits.
For better absorption, consider supplements like zinc citrate or zinc picolinate. Taking zinc with food can help reduce the risk of gastrointestinal discomfort. If your daily zinc intake exceeds 40 mg, it's important to also take 2 mg of copper for every 15 mg of zinc to prevent copper deficiency.
Potential Side Effects
Zinc is generally safe when taken as directed. In studies where women with PCOS used 50 mg of zinc daily for two months, no adverse effects were noted. However, exceeding the upper intake limit of 40 mg per day can cause side effects such as nausea, vomiting, stomach cramps, diarrhea, headaches, and loss of appetite. Some users may experience a metallic taste, dizziness, or increased sweating.
Long-term use of high doses can lead to issues like copper deficiency, weakened immunity, and lower HDL cholesterol levels. Zinc may also interfere with certain medications, including quinolone and tetracycline antibiotics, as well as treatments for rheumatoid arthritis. Additionally, taking zinc alongside iron or calcium can reduce its absorption.
Before starting zinc supplementation, consult your healthcare provider, especially if you are on medications or have pre-existing health conditions. Zinc is not recommended for individuals with hemochromatosis.
3. Omega-3 Fatty Acids
Omega-3 fatty acids, like inositol and zinc, play a role in addressing hormonal imbalances at the heart of PCOS, offering another option for managing hirsutism. These essential fats, particularly EPA and DHA, are known to lower androgen levels and reduce inflammation, both of which are key factors in PCOS.
Primary Mechanism
Omega-3s work by lowering both bioavailable and total testosterone levels while increasing SHBG (sex hormone-binding globulin), which helps reduce androgen activity. Additionally, their anti-inflammatory properties target the chronic, low-grade inflammation often seen in PCOS, which can improve insulin sensitivity and indirectly reduce hyperandrogenism. These biochemical effects form the foundation for the clinical benefits observed in various studies.
"In summary, n-3 PUFAs have the potential to ameliorate metabolic issues linked to polycystic ovary syndrome (PCOS), such as insulin sensitivity, lipid metabolism, and hormonal balance."
– Laila Albardan et al., Department of Nutrition and Health, United Arab Emirates University
Benefits for Hirsutism
Building on these mechanisms, clinical research highlights the positive effects of omega-3 supplementation on hirsutism and menstrual regularity. Many trials report notable improvements in hirsutism scores and hormonal profiles. However, not all studies align - one 2017 trial using 2 grams daily for six months found no significant change in hirsutism scores, though other hormonal benefits were observed. Interestingly, a case-control study involving 325 women found that those with the highest omega-3 levels were 40% less likely to have PCOS.
"Omega-3 fatty acids reduce testosterone in PCOS, improve menstrual regularity, hirsutism and hormone levels."
– Erica Nikiforuk, ND, White Lotus Clinic
Dosage Recommendations
For managing PCOS and hirsutism, doses between 1.5 to 3.5 grams of combined EPA and DHA daily have shown effectiveness. The European Food Safety Authority deems up to 5 grams per day safe for most adults. Specifically, 1.5 grams daily has been linked to improvements in hirsutism, while doses ranging from 1 to 4 grams may enhance insulin sensitivity.
To meet these therapeutic levels, cold-water fish like salmon, mackerel, and sardines are excellent dietary sources. Alternatively, high-quality fish oil supplements, particularly those derived from smaller fish (to minimize mercury exposure), can help achieve consistent intake. Taking supplements with meals may boost absorption and reduce digestive discomfort.
Potential Side Effects
Omega-3 supplements are generally well-tolerated, but mild side effects such as fishy burps, nausea, headaches, and digestive upset may occur. These can often be minimized by taking supplements with meals or storing them in the freezer. More serious concerns include increased bleeding risk when combined with blood thinners and potential over-reduction of blood pressure when taken alongside antihypertensive medications. Additionally, birth control pills may interfere with omega-3s’ triglyceride-lowering effects, and individuals with fish allergies should avoid fish oil supplements altogether.
While rare at recommended doses, very high intakes of omega-3s could lead to complications like bleeding episodes, blood sugar fluctuations, or weakened immune function. Always consult with a healthcare provider before starting supplementation, particularly if you’re managing existing health conditions or taking medications.
4. Magnesium
Magnesium is a key player in over 300 enzyme systems, particularly those involved in energy production and insulin signaling. That said, when it comes to improving hirsutism in PCOS, magnesium on its own doesn't seem to make a big difference.
Primary Role
Magnesium is a vital cofactor for enzymes that regulate glucose metabolism and insulin sensitivity.
"Magnesium plays a critical role in insulin signaling and glucose metabolism."
– Angela Grassi, MS, RDN, LDN, Verywell Health
Research shows that many women with PCOS have lower magnesium levels compared to those without the condition. In fact, about one in four women with PCOS may not be getting enough magnesium from their diet. One study found their average intake to be just 233 mg/day - well below the recommended 320 mg/day for adult women.
Impact on Hirsutism
Studies indicate that magnesium supplements alone, particularly in doses like 250 mg/day of magnesium oxide, don't significantly improve hirsutism or related hormonal issues in PCOS.
"A study found that a 250 mg/day dose produced no benefits for hirsutism. Positive effects in earlier studies likely resulted from nutrient synergy."
– Mahsa Gholizadeh‐Moghaddam et al., Health Science Reports
However, magnesium may work better when paired with other nutrients. For instance, a 12-week trial combining 250 mg/day of magnesium with 400 mg/day of vitamin E showed a notable reduction in hirsutism. This suggests that magnesium's benefits might be amplified when used alongside other supplements.
Dosage Guidelines
For adult women, the recommended daily magnesium intake is 320 mg. Studies that found no effect on hirsutism used doses of 250 mg/day of magnesium oxide. On the other hand, for managing insulin resistance, doses of 300–750 mg/day over four months have shown positive results. It's worth noting that supplemental magnesium intake should stay below 350 mg/day to avoid potential side effects.
The type of magnesium matters, too. Forms like magnesium glycinate, aspartate, citrate, lactate, and chloride are absorbed more efficiently than magnesium oxide or sulfate. Switching to one of these forms could improve results. To maximize absorption, it's best to take magnesium after meals, as absorption typically occurs over 6–7 hours.
Possible Side Effects
Magnesium supplements are generally safe, but taking 3–5 grams daily could cause issues like diarrhea, stomach upset, or dehydration. Going over the tolerable upper intake of 350 mg/day from supplements can lead to magnesium buildup, potentially causing low blood pressure, weakness, or confusion.
People with kidney disease or heart conditions (like bradycardia or heart block) should consult their doctor before taking magnesium supplements. Certain medications - such as birth control pills, diuretics, and proton pump inhibitors - can interfere with magnesium absorption. High intakes of calcium, iron, copper, or zinc, as well as foods rich in oxalic or phytic acid (like spinach, seeds, and grains), may also reduce absorption. Thankfully, magnesium toxicity is rare, as the body usually eliminates excess amounts through urine.

5. Saw Palmetto
Saw palmetto can be a helpful addition to other strategies for managing hormonal imbalances, particularly for addressing hirsutism. This natural extract works by targeting the hormonal causes of excess hair growth, making it a potential ally in reducing PCOS-related symptoms.
How It Works
Saw palmetto blocks the enzyme 5α-reductase, which is responsible for converting testosterone into DHT (dihydrotestosterone). By inhibiting this enzyme, it reduces DHT production and its ability to bind to androgen receptors - cutting this binding activity by nearly 50%, according to research.
Benefits for Hirsutism
Studies suggest saw palmetto can offer noticeable improvements for hirsutism. For example, in one clinical trial involving women with facial hirsutism, a topical cream containing saw palmetto extract reduced excess hair by 16% after just one month and by 29% after two months.
Another study, which included both men and women, found that a nutritional supplement with saw palmetto increased hair density in 83% of participants. Among women, 33% reported significant improvements in hair thickness. Its anti-inflammatory properties may also help alleviate inflammation often linked to PCOS.
Suggested Dosage
Saw palmetto is typically taken in doses ranging from 320 to 450 mg daily, standardized to contain 45% fatty acids. Some studies have used lower doses, such as 160 mg twice daily, while others have tested up to 400 mg daily. Here's a quick breakdown:
| Form | Dosage | Frequency | Notes |
|---|---|---|---|
| Capsules | 320–450 mg | Once daily | Standardized to 45% fatty acids |
| Extract | 160–450 mg | Twice daily | Benefits often appear after about six weeks |
| Liquid Extract | 1 tsp | Once daily | Take with food to minimize stomach upset |
For best results, a six-week trial is recommended. Taking saw palmetto with food can help improve absorption and reduce the risk of digestive discomfort.
Possible Side Effects
Saw palmetto is generally safe, but mild digestive issues like nausea, diarrhea, or stomach upset can occur. Taking it with meals usually helps reduce these effects.
Certain precautions are necessary. Women who are pregnant or breastfeeding should avoid saw palmetto because of its influence on reproductive hormones. Additionally, those using hormone-based contraceptives or blood thinners should consult a healthcare provider before starting. If you're planning surgery or undergoing hormone testing for fertility, it's wise to stop using saw palmetto in advance to prevent any interference.
6. Reishi Mushroom
Reishi mushroom, also known as Ganoderma lucidum or Red Reishi, offers a natural way to address some of the hormonal imbalances tied to PCOS-related hirsutism. Its standout feature is its ability to reduce the effects of testosterone, especially its conversion into a more potent form, making it a promising option for managing unwanted hair growth caused by PCOS.
How It Works
Reishi’s primary action lies in its ability to inhibit the enzyme 5-alpha reductase. This enzyme is responsible for converting testosterone into dihydrotestosterone (DHT), a stronger androgen that contributes to hirsutism. By blocking this process, reishi helps lower DHT levels, tackling one of the main drivers of excess hair growth in women with PCOS.
"Specifically for PCOS, it has been shown to lower androgen levels by inhibiting five alpha-reductase, which is the enzyme that converts testosterone to DHT. Higher levels of DHT lead to hirsutism or unwanted hair growth in women."
– Dr. Jen, Board-certified physician specializing in integrative and functional medicine
Benefits for Hirsutism
Reishi’s anti-androgenic properties directly target DHT, addressing one of the root causes of hirsutism. But its benefits don’t stop there. Reishi is also classified as an adaptogen, meaning it may help the body better manage stress - a known aggravator of PCOS symptoms. Additionally, it is believed to support liver detoxification and strengthen the immune system.
That said, research specifically examining reishi’s effects on PCOS is still in its early stages. For instance, one study on mice found that reishi extract alone didn’t significantly reduce hair growth compared to a control group. However, when combined with tea tree oil, improvements were observed.
How to Use Reishi
Reishi mushrooms are available in various forms, including dried, powdered, and capsule supplements. You can also add powdered reishi to food or beverages. Since there’s no established dosage specifically for PCOS-related hirsutism, it’s best to follow the dosing instructions provided on the product label. Consulting a healthcare professional can also help you determine the right amount for your needs.
Possible Side Effects
For most people, reishi is considered safe and well-tolerated. However, some individuals might experience mild digestive discomfort, such as nausea. In studies involving topical application on mice, no skin irritation or swelling was observed. As with any supplement that influences hormones, it’s wise to consult your healthcare provider before starting reishi, particularly if you’re on other medications or have existing health conditions.
Supplement Comparison: Pros and Cons
When choosing supplements to address PCOS-related hirsutism, understanding the strengths and limitations of each option is essential. Below is a comparison of six commonly discussed supplements, summarizing their effectiveness, safety, and ease of use:
| Supplement | Effectiveness for Hirsutism | Safety Profile | Ease of Use |
|---|---|---|---|
| Inositol (Myo- and D-Chiro) | Strong evidence for hormonal balance in PCOS | Very safe with fewer side effects than metformin | Easy – available in powder or capsule form |
| Zinc | Shown to reduce hirsutism scores significantly (1.71 vs. 0.29 in placebo) | Safe at or below 40 mg/day; excess may cause nausea or stomach upset | Moderate – best taken with food to avoid discomfort |
| Omega-3 Fatty Acids | Limited direct evidence for hirsutism; known anti-inflammatory properties | Generally safe for most people | Easy – widely available; may cause fishy aftertaste |
| Magnesium | Minimal impact when used alone | Safe for most; caution for those with kidney disease | Easy – available in highly absorbable forms |
| Saw Palmetto | Limited evidence for direct PCOS-related benefits | Generally well-tolerated | Easy – often found in combination formulas |
| Reishi Mushroom | Preliminary findings suggest potential anti-androgen effects | Safe for most; may cause mild digestive upset | Easy – available in powder, capsules, etc. |
Breaking Down the Options
Zinc stands out for its effectiveness in reducing hirsutism. Clinical trials have shown significant improvements in hirsutism scores compared to placebo. However, it's important to stay within the recommended daily limit of 40 mg to avoid side effects like nausea or stomach cramps. Zinc may also interfere with certain medications, such as antibiotics, and excessive intake can impact copper levels and immunity.
Inositol is another strong contender, especially for its role in balancing hormones in women with PCOS. Research supports the use of a 40:1 ratio of myo-inositol to D-chiro-inositol, which has shown promising results with a solid safety profile. It's also easy to incorporate into your routine, as it comes in both powder and capsule forms.
Magnesium shows mixed results when it comes to hirsutism. While a single dose of magnesium alone may not significantly impact symptoms, combining it with other nutrients could enhance its benefits. This highlights the potential of nutrient synergy in addressing hormonal imbalances.
Omega-3 fatty acids, saw palmetto, and reishi mushroom have limited direct evidence for improving hirsutism. However, omega-3s are well-known for their anti-inflammatory properties, making them a worthwhile addition to your regimen for overall health. Saw palmetto and reishi mushroom may offer potential benefits, but more research is needed to confirm their effectiveness for hirsutism.
Practical Considerations
When it comes to ease of use, personal preferences and sensitivities play a big role. Inositol powder can be mixed into beverages for convenience, while zinc is best taken with food to avoid stomach upset. Omega-3 supplements are widely available, but some users may find the fishy aftertaste unpleasant. Gradually increasing doses can help minimize side effects for most supplements.
Ultimately, the best supplement - or combination of supplements - depends on your individual needs and health profile. Consulting with a healthcare provider can help you determine the right approach and dosages for your situation.
Conclusion
Managing PCOS-related hirsutism often calls for a personalized approach to supplementation, as individual factors can significantly influence effectiveness.
Supplements like inositol and zinc have shown promise in clinical studies. For example, taking inositol (2–6 grams daily) may help improve ovulation and lower androgen levels, while zinc (20–30 mg daily) can support better insulin sensitivity and reduce androgenic symptoms. However, these benefits come with potential risks. Saw palmetto, for instance, might lower estrogen levels, which could be problematic for women already dealing with low estrogen. This is particularly important since women with PCOS are up to three times more likely to face gallbladder issues. Additionally, excessive zinc intake can lead to copper deficiency, and high doses of inositol may aggravate symptoms instead of alleviating them.
The key takeaway? Personalized care is crucial. A healthcare provider can help identify your specific PCOS type, evaluate possible drug interactions, and ensure supplements complement - rather than replace - medical treatments and lifestyle adjustments.
