Not Down with ‘D’

I am in a quandary over the dose of Vitamin D I was prescribed in early January and I wrote about in Vitamin D(on’t). As I wrote, I wish I went armed with more information before agreeing to take this 50,000 IU weekly for 3 months prescribed by my physician. I have been taking this dose for 3 weeks now and without going in for a blood test I won’t know if there has been an increase in my 25-hydroxyvitamin D level. That test isn’t supposed to occur the end of March.

Further discussion and research having me raising a red flag to this “vitamin” and I am not sure my physician is out for my health. Instead of getting clarity on the situation I am more confused. How do I tell my physician I don’t want to take his recommendation, backed with studies and information I have gleaned from the Internet?

Just because I was not trained in the medical field doesn’t mean I need to agree with my doctor. Without his consent I took myself off a statin last year and I am very close to taking myself off the Vitamin D. With or without him agreeing. I wish I had multiple blood test results to compare my 25(OH)D levels, but I don’t. December, 2011 was the first (and not the last) time this level had been measured. I do believe I can attribute it to my job. I spend approximately 10 hours in darkness considering I am up at 4am and don’t leave work until 2pm.

Over the course of 5 years I can think my 25(OH)D level has decreased, again because of my job. During the summer time I will end up spending more time outside, in the sun but making soaking up the sun can’t be a seasonal thing and must occur year around.

From the National Institutes of Health, “Practically all people are sufficient at levels ≥50 nmol/L (≥20 ng/mL); the committee stated that 50 nmol/L is the serum 25(OH)D level that covers the needs of 97.5% of the population.” My 25(OH)D level was recorded as 23 in December, 2011. By way of comparison, my wife was recorded at a level of 16 last month. The nurse practitioner prescribed her to take 1000 IU a day. Yet I am taking 50000 IU weekly for an 25(OH)D level of 23 or approximate 7142 IU daily! The numbers just don’t work for me.

A vitamin D deficiency can occur when usual intake is lower than recommended levels over time, exposure to sunlight is limited, the kidneys cannot convert 25(OH)D to its active form, or absorption of vitamin D from the digestive tract is inadequate. Vitamin D-deficient diets are associated with milk allergy, lactose intolerance, ovo-vegetarianism, and veganism” (source). I don’t think I have been following a plant-based, whole food lifestyle long enough to see my level as a “deficiency.” Two abstracts agree, “people with occupations that limit sun exposure are unlikely to obtain adequate vitamin D from sunlight.” (source, source).

As with ANY medication prescribed the list of side effects are rather appalling. This list is courtesy of the Mayo Clinic.

Remind me, WHY should I be taking this? For my healthy? To support my physician’s wallet? To date, I haven’t noticed any “early symptoms” to speak of. I have been reading C: The Blog, there are some interesting comments from other individuals using Vitamin D at varying levels.
