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.
