High testosterone levels, particularly in women, can lead to various health issues, including polycystic ovary syndrome (PCOS). PCOS is a common hormonal disorder affecting millions and is often characterized by elevated testosterone, contributing to symptoms like weight gain, acne, and irregular periods. Fortunately, dietary adjustments can play a significant role in managing testosterone levels naturally. Certain foods possess anti-androgenic properties, meaning they can help reduce the effects of male hormones like testosterone. This article explores five food categories that research suggests may help lower testosterone levels, especially beneficial for individuals managing PCOS symptoms.

Vegetable Oils Rich in Polyunsaturated Fats
Vegetable oils such as canola oil, soybean oil, and corn oil are excellent sources of polyunsaturated fats, often abbreviated as PUFAs. These healthy fats have been studied for their potential to influence hormone levels. While much of the research focuses on male subjects, findings suggest that polyunsaturated fats may contribute to lower testosterone levels.
A study published in the Asian Journal of Andrology in 2017, for example, indicated that increased intake of polyunsaturated fats was linked to decreased total and free testosterone levels in men. Although more research is needed specifically on women with PCOS, the existing evidence suggests a potential benefit for hormonal regulation in females as well.
Furthermore, a 2021 review in Life Sciences proposed that polyunsaturated fat consumption could not only aid in reducing testosterone in individuals with PCOS but also improve menstrual cycle regularity and insulin sensitivity. These improvements can have a positive impact on fertility and the management of type 2 diabetes, conditions frequently associated with PCOS.
Flax Seeds: A Plant-Based Powerhouse
Flax seeds stand out as a particularly potent plant-based source of polyunsaturated fatty acids, making them a valuable addition to a diet aimed at managing PCOS. They are especially rich in alpha-linolenic acid (ALA), a specific type of omega-3 fatty acid.
Research has highlighted the benefits of flax seeds for women with PCOS. A 2020 study in the Nutrition Journal found that daily consumption of 30 grams of flaxseed powder led to improved cholesterol profiles and significantly reduced insulin levels in women with PCOS. These positive changes are believed to be linked to the testosterone-lowering effects of ALA. The study also noted improvements in menstrual cycle regularity and weight management among participants.
Fatty Fish: Omega-3 Fatty Acid Source
Fatty cold-water fish, including salmon, herring, mackerel, tuna, and sardines, are renowned for their high content of omega-3 fatty acids. These polyunsaturated fats are widely recognized for their heart-health benefits, and research indicates they may also play a role in hormone regulation. Fish and oysters are among the richest dietary sources of omega-3s.
A 2013 study in the Iran Journal of Reproductive Medicine explored the effects of omega-3 supplementation on women with PCOS. The study involved 78 women with PCOS who received either a 3-gram daily dose of omega-3 supplements or a placebo over eight weeks. The results demonstrated that the omega-3 group experienced lower testosterone levels compared to the placebo group. Additionally, women in the omega-3 group were significantly more likely to report regular menstrual periods. Current dietary guidelines generally recommend consuming two servings (3.5 ounces each) of cold-water fish per week to reap these health benefits.
Spearmint Tea: Herbal Anti-Androgen
Spearmint tea has emerged as a promising natural remedy for managing PCOS symptoms, particularly due to its anti-androgenic properties. Studies suggest that spearmint can influence hormone levels in a beneficial way.
Animal studies have shown that spearmint extract can lower testosterone levels while simultaneously increasing estrogen and progesterone. These hormonal shifts are favorable for normalizing menstrual cycles and enhancing fertility in individuals with PCOS. Human research is still in the early stages, but a 2010 study in Phytotherapy Research reported that drinking spearmint tea twice daily for a month led to reduced testosterone levels and a decrease in self-reported hirsutism (excessive hair growth) in women with PCOS.
Red Reishi Mushrooms: Traditional Remedy
Red reishi mushrooms, known as lingzhi in traditional Chinese medicine, are recognized for their potent anti-androgenic effects. These mushrooms appear to interfere with the enzyme 5-alpha-reductase, which converts testosterone into dihydrotestosterone (DHT), a more potent androgen.
Elevated DHT levels can exacerbate PCOS symptoms such as acne, hirsutism, and androgenic alopecia (hair loss). By inhibiting 5-alpha-reductase, red reishi mushrooms may help reduce the impact of DHT and, consequently, alleviate these symptoms. Red reishi mushrooms are available in dried or powdered forms and can be found in health supplement stores and Asian markets.
In Conclusion
For individuals, especially women with polycystic ovary syndrome (PCOS), managing high testosterone levels is crucial for overall health and well-being. While further research is always valuable, current evidence suggests that incorporating certain foods with anti-androgenic properties can be a helpful strategy. Polyunsaturated fats from vegetable oils and flax seeds, omega-3 fatty acids from fatty fish, spearmint tea, and red reishi mushrooms all show promise in naturally lowering testosterone levels and potentially alleviating PCOS symptoms such as weight gain, acne, and menstrual irregularities. Dietary changes, alongside medical advice, can be a powerful tool in managing hormonal balance.
