Polycystic Ovarian Syndrome (PCOS) used to only be considered in overweight women with irregular menstrual cycles and signs of excess androgens such as abnormal hair growth. It is now known that PCOS exists in women of all body types and with many variable symptoms. For example, one woman with PCOS may be overweight with irregular menses while another PCOS sufferer may be of normal weight with acne and facial hair.

With this in mind, it is important to consider PCOS when more than one of the following signs or symptoms are present:

– menstrual irregularities, especially longer than average cycles or absent
– excessive dark, coarse hair growth on body or face
– male pattern baldness
– insulin resistance and/or high blood sugar levels
– acne or dark skin patch developments (acanthosis nigricans)
– elevated testosterone levels on blood tests
– infertility or recurring miscarriages
– polycystic ovaries (determined on ultrasound)
– excess weight, especially in the abdominal region

So, what if you have been diagnosed with PCOS? Where do you start? As always, you should begin with diet and lifestyle modifications. Many of these recommendations are similar to those made for type 2 diabetics in order to balance blood sugar levels and reduce abdominal fat when present: high fibre, low glycemic-index, high protein, and healthy fats are key modifications to focus on. This means more vegetables, legumes, and lean meats, with less processed foods, refined sugars, and grains. Elimination of foods which may cause sensitivities is extremely important and individualized, with dairy, gluten, and eggs being the most common offenders. The addition of moderate exercise (1 hour sessions of any type, three times per week) can improve many PCOS markers as well, including insulin resistance and reproductive function. 

When it comes to supplementation, the list can be extensive and it is important to speak with a qualified practitioner to determine which ones are tailored toward your particular PCOS presentation. In any case, here are some to consider:

Chromium: Many people are familiar with chromium and its role in regulating blood sugars via insulin receptor sensitivity. Given that PCOS sufferers also exhibit insulin resistance, it is no surprise that 200-1000mcg/day of chromium picolinate has been found to reduce high insulin in women with PCOS. Individuals with PCOS have also been found to have lower blood levels of this mineral when compared to women without the syndrome.

Vitamin D: Vitamin D3 has been found deficient in the vast majority of the population, including PCOS women. Vitamin D3 supplementation in PCOS has been shown to improve menstrual regularity, androgen profiles, glucose metabolism, and follicle maturation in various studies. Get your blood levels tested in order to determine optimal dosing.

Inositol: This nutrient was discussed previously in the context of treating mood disorders with a short bit on PCOS. Check it out here, but know that myo-inositol can improve egg quality and insulin sensitivity. Myo-inositol for the purposes of PCOS tends to be effective at dosages between 0.5-2.0 g/day.

N-Acetyl Cysteine (NAC): This amino acid is best known for its ability to up-regulate the production of glutathione and provide anti-oxidant support. In cases of PCOS, NAC not only acts against oxidative stress, but it has been shown to improve hormonal markers, ovulation rates, and pregnancy rates. Effective dosages typically range from 1000mg-1500mg/day.
