Sunny D-lites & PCOS



Vitamin D, commonly referred to as the sunshine vitamin, is a fat-soluble vitamin but it is also a steroid hormone. A recent study found that women with PCOS have lower levels of Vitamin D compared to non-PCOS women and that this deficiency is associated with a greater incidence of insulin resistance and high cholesterol (Krul-Poel et al., 2018).

Furthermore, some have suggested that Vitamin D may play a role in the prevention of Type 2 Diabetes Mellitus (Grimnes et al., 2010). A recent meta-analysis highlights the increased prevalence of Type 2 Diabetes Mellitus and Impaired Glucose Tolerance in those with PCOS (Kakoly et al., 2018).


I had my own level of serum Vitamin D tested and discovered I was in fact deficient. You need to know if you are deficient BEFORE any supplementation as too much Vitamin D is said to be toxic. I find that using a spray version of Vitamin D3 is best as it is quickly and easily absorbed into the body and keeps my levels optimal.


Dietary sources of Vitamin D that I use include cod liver oil, Salmon (preferably wild-caught not farmed), mackerel, tuna, sardines, and egg yolks from free range chickens. Everyone’s baseline Vitamin D serum level differs so dosage has to be personalised therefore you must speak to your healthcare provider.


Vitamin D plays numerous roles in maintaining health and as you can see may have an important role in PCOS!
