Vitamin D: Cure-All or Commercial Success?

Nowadays, when the internet supplies us with so many fantastic sources of information on everything from our health to the best holiday deals, it’s important to know what’s real and what might just be clever advertising. Though our media sources are faster and cover more stories than ever before, this doesn’t mean their reporting should be taken as gospel. Just like frenzied shoppers, journalists also do their best to find easy-to-wrap-up news stories that are consistent with the popular trends in our public’s eye. Thus, reporting often reflects what citizens want to read rather than the truth.

The recent controversy over vitamin D is a prime example of this fact flip-flopping. (So is the controversy over Wiki-leaks, but we won’t get into that.)

Vitamin D is especially interesting when it comes to nutritional supplementation, as it’s the only vitamin that is also a hormone. In its dual role, vitamin D is essential to the body’s absorption of calcium. Without enough vitamin D, a body is more likely to have lower bone density and other complications associated with low blood levels of calcium.

D is also the only vitamin that does not need to be consumed in food – we can produce it when our skin is exposed to direct sunlight. Thus, unlike with most other nutrients, a person cannot ensure that he or she is getting enough vitamin D simply by eating a balanced diet, (though of course, this helps tremendously!) but should also make efforts to include outdoor activity and gentle exposure to the elements in his or her daily activities. People who have skin with a darker pigment and those who live in regions where sunshine isn’t strong or prevalent (think: upper midwest) are more likely to show a deficiency in vitamin D.

Perhaps it is these curious characteristics of the vitamin that contributed to scientific communities’ and mass media’s recent obsession with its benefits. Perhaps it was simply part of the eternal attempt to locate that panacea of a drug.

Hanna, thank you so much for the thought-provoking article. I completely agree with you. I am a BRCA2 carrier who comes from 3 generations of breast cancer survivors. I had a prophylactic double mastectomy and oopherectomy to avoid my own day of diagnosis. So I follow cancer/health news very closely and I am often exhausted both by the constant flow of supernutrient stories and the frequent ping-ponging back and forth that follows - benefits vs. risks and studies questioning studies.

That said, I wrote about this newest supernutrient here: http://www.4women.com/blog/?p=260. Since writing that post, I find daily stories either supporting, questioning, or seemingly taking a polar position on the potential risks/benefits of Vitamin D supplementation. What to believe!!!???? Articles such as your's promoting common sense balance in life, vs. imbalance supplemented with pills are needed.
Thanks for sharing.

Thank you very much for your comments!

I just want to reiterate that I didn't mean to imply that Vitamin D isn't a crucial part of each person's diet - it is! Instead, I was hoping to point out that over-emphasizing or over-glorifying one single vitamin over all the other essential nutrients a body needs to function can be dangerous. Past studies claiming that Vitamin D is the panacea of Vitamins is still new and unreliable, and it is important for consumers to think critically about what they are reading. Concentrating on balance in diet and lifestyle is far more advantageous to your health than relying on a single supplement - no matter what you read.

Hope that clarifies!

If one asks the right questions, like here:


it may become easier to understand vitamin D. Without wondering about why the body choses to use vitamin D, you're left with the known fact that it is necessary to mantain bones and you have some not so rigorously established results that it is involved in other processes.

I am not sure why you have chosen to believe experts when they claimed in their report that they only consider bone health. Also they did not separate their findings between D2 and D3. Basically the report from the IOM is not a report about the facts but a report to maintain the population with vitamin D levels below peoples in a sunny country. The amount they recommend will not get you there.
