Misinformation Touting Vitamin D2 Still Prevalent

with 4 comments

In spite of the literally thousands of studies from the past four years affirming, confirming and then reaffirming the stark contrast between Vitamins D2 (Ergocalciferol) and D3 (Cholecalciferol) in terms of supplemental value, there is still a great deal of misinformation being fed to the public touting the supposed benefits of Vitamin D2.

Let me be perfectly clear: Vitamin D3 is the form of the D Vitamin that offers unprecedented health benefits to humans whether ingested via food or supplements or absorbed through exposure to sunlight. Vitamin D2 has been under heavy scrutiny the past few years by medical professionals who are informed and up-to-date on the subject, but some apparently either stopped paying attention some time ago or simply choose not to acknowledge the trove of research backing claims of D3′s superiority.

I came across the following over at Revolution Health, a site I otherwise respect:

What is Vitamin D (Ergocalciferol (Vitamin D2)?

Ergocalciferol is vitamin D2. Vitamin D is important for the absorption of calcium from the stomach and for the functioning of calcium in the body.

Ergocalciferol is used to treat hypoparathyroidism (decreased functioning of the parathyroid glands).

Ergocalciferol is also used to treat rickets (softening of the bones caused by vitamin D deficiency) or low levels of phosphate in the blood (hypophosphatemia).

Ergocalciferol may also be used for other purposes not listed in this medication guide.

Given the fact that Revolution Health sells itself as being a credible source for health news and generally backs it up, I was quite surprised when I found out they were among the ill-informed media erroneously talking up Vitamin D2, claiming that D2 supplements provided substantial health benefits.

The reality is that D2 offers few if any benefits to humans. D3 is something of a supervitamin/hormone, but D2 is little more than a synthetic product. It was created for the sole purpose of being sold, as where its counterpart is a completely natural and bioavailable substance that is easily broken down for use by the body.

  1. If you go the pharmacy, Vitamin D is being distributed, but I recently found out from my pharmacist that it was D2 and not D3, because I wanted to find out more, since I had a deficiency in Vitamin D. I wonder if doctors know what is going on, but tend to not share this info with their patients, because they assume they are illiterate or uneducated. Check out the Vitamin D Council site as well. I’m feeling much better now!

  2. Karmjeet, thank you for stopping by the site and for sharing your experience. As for the doctors, I am hesitant to suggest that any doctor would deliberately mislead his or her patients. It is only within the past five or six years that differentiation between different forms of Vitamin D became commonplace, and only within the past 24-30 months that the media has started to catch on to the mountains of research coming out about Vitamin D3, its health benefits and the consequences of not getting enough.

    I would be much more inclined to believe that many doctors for whatever reason aren’t up-to-speed with the developments involving cholecalciferol. I think the fault lies primarily in the system that places so much emphasis on pharmaceuticals and reactionary care as opposed to preemptive care and prevention. The individuals are but products of the system, and most likely genuinely believe that they are doing the best they can for their patients.

  3. Wit having diabetes for more than five years I would like to share something about D2 . I use to be on two dif. Types of insulin three times a day and blood sugar was always over 300 also was on 6 dif. Oral meds.
    After starting D2 50,000 units twice a week I have not used insulin in over a year and blood sugar is never over 140. To make it short D2 has to be converted to D3 for the body to use and the conversion process transports insulin more effectively..

  4. Please read the effects of diet/nutrition as well, and the implications of Vitamin D synthesis due to animal intake in our diets and how it prohibits the intake of natural Vitamin D3 which is originally derived from nature via sunlight. Please read up on plant intake in our diets as well and how it effectively processes Vitamin D, unless you have other problems such as kidney/liver problems. Diet/nutrition definitely matter. Pharmaceuticals treat the symptoms but not the underlying fundamental issue.
