Last year, when I had my blood Vit D tested, it was very low (7ng/ml if I remember correctly). After an year of Vit D 5000 IU per day, my serum Vit D came upto 25ng/ml which is still below normal. I live in San Diego and last year I spent a lot of time outside to make sure my Vit D deficiency would be resolved....

A couple of my non-PD friends also had very low serum Vit D (5-10ng range) and are on 50,000IU vit D per week schedule. My Primary care physician told me that Vit D deficiency has become very common these days and he is recommending Vit D supplements to many of his patients. This is in San Diego where we have 300 days of Sun in an year and people are almost always in T-shirts and shorts. Something is seriously wrong here.....

How many of you had your Vit D levels tested and what are your Vit D values?

Thanks
