Vitamin D has gained much well-deserved attention over the past year.
After all, this nutrient isessential to our immune system.
- Like me, I know many of you are vitamin D fans.
That is the question.
Allow me to use an analogy to explain.
by choosing toshare the Olympic goldrather than have a jump-off.
They both left Tokyo with gold medals.
Vitamin D3 and D2 are…nothinglike that.
Why do you need vitamin D?
Despite its importance, there is clear data demonstrating how widespread the vitamin D gap is in our country.
This is where supplementation can helpbut only if you choose the right form.
Why all forms of vitamin D aren’t created equal.
Your options are vitamin D3 or vitamin D2.
- And here’s the bottom line: These two nutrients are not biologically equivalent or interchangeable.
Any suggestion that vitamin D3 and D2 are both good options falls into the “bad science” bucket.
Vitamin D3 and D2 have historically been differentiated by their origin: animal versus plant.
Vitamin D3 is almost always animal-derived, from lanolin from sheep’s wool.
This is a fine source of D3 and the most common in the market.
In contrast, vitamin D2 is plant-derived from irradiated yeast and mushrooms mostly.
But that’s old news.
Albeit rare, there are even certified organic plant-origin varieties of D3.
So, where might you find vitamin D3 vs. D2?
Benefits of vitamin D3.

Vitamin D3 has superior bioefficacy.

Why does this ultimately matter?

How much better is vitamin D3 at increasing 25(OH)D levels?
Some studies estimate that thepotency of D3 is a whopping 87% higher than D23.
Vitamin D3 has superior stability.
Bottom line.
Sorry, vitamin D2 simply isn’t suitable for supplementation.
Now, you might see why vitamin D2 does not “medal” in the nutrition “Olympics.”
