85% Of Women With PCOS Are Also Vitamin D Deficient — Here's Why

Polycystic ovary syndrome (PCOS) is a hormonal disorder that affects up to 20% of reproductive-aged women1 worldwide, according to a 2020 Journal of Human Reproductive Sciences review. Defined by abnormally high levels of hormones called androgens, PCOS is a generally misunderstood disorder that causes everything from menstrual irregularity to excess hair growth and acne. 

Science shows that low vitamin D levels (i.e., vitamin D deficiency) may play a part in exacerbating PCOS symptoms—including menstrual irregularity, infertility, obesity, hyperandrogenism, and insulin resistance. An essential vitamin that's widely underconsumed, vitamin D helps promote balanced insulin levels, hormonal health, healthy body composition, and so much more.

Whether you've been diagnosed with PCOS or not, ensuring your vitamin D status is sufficient [hint: the golden standard is a 25(OH)D serum level of 50 ng/ml or higher] can help support your hormonal, metabolic, and whole-body health. To achieve vitamin D sufficiency, the average person needs to consume 5,000 IU of vitamin D3 (not D2) daily.

The problem? Getting adequate vitamin D from just food and safe sun exposure is practically impossible. A high-quality vitamin D supplement, however, can help you reach and maintain healthy vitamin D status effectively and efficiently.
