Are vitamin D2 and vitamin D3 the same? I don't think so. 

Vitamin D2:

• Is mainly made synthetically 

• You can get vitamin D2 from mushrooms (but many people don’t do this)

• There are not a lot of studies on vitamin D2

  • The studies on vitamin D2 do not have the decreased mortality benefit that D3 has 

• Vitamin D2 is less expensive, but you need more of it to see results 

Vitamin D3:

• You can get vitamin D3 from animal sources (fatty fish, red meat, cod liver, cod liver oil, liver, egg yolks, and butter)

• There are studies on vitamin D3

  • Vitamin D3 is 5x faster in the conversion 

• Vitamin D3 is less toxic

• Vitamin D3 is more stable
