This "new" research suggests that vitamin D3 is more beneficial than vitamin D2. This has been known for decades. I don't know anyone who knows anything about holistic health recommending vitamin D2. The only people who prescribe D2 it are medical doctors. Why? It's a prescription that you get from pharmacies so it can be covered by insurance. It's based on the fallacy that anything prescription much be better than what is over the counter.
Researchers analyzed 11 trials with 655 adults and discovered that taking vitamin D2 supplements decreases the body's vitamin D3 levels, a previously unknown effect.
