PCOS is associated with insulin resistance, type 2 diabetes, obesity, and dyslipidemia, which has made chromium a supplement of interest for PCOS. While chromium does seem to reduce markers of insulin resistance (HOMA-IR) in people with PCOS, there is no obvious effect on BMI, fasting blood sugar or insulin, or lipid profiles. Additionally, there is some evidence that chromium supplementation may actually increase levels of testosterone (a negative effect in PCOS),[1] but this has not consistently been found.[2] Overall, there is insufficient evidence to support the use of chromium for PCOS.

Chromium is of interest for polycystic ovary syndrome (PCOS) due to its potential to reduce insulin resistance, but it does not significantly affect BMI, fasting blood sugar, or lipid profiles. Additionally, there is insufficient evidence to support its use for PCOS, and some studies suggest that it may increase testosterone levels, which could be detrimental.
