Is vitamin D the same as D3?

No, vitamin D is an umbrella term for two main forms, D2 (ergocalciferol) and D3 (cholecalciferol); they are similar but come from different sources (plants vs. animal/sun) and D3 is generally considered more effective at raising blood levels, though both help bone and immune health. Think of "vitamin D" as the category (like "car") and D2/D3 as the types (like "sedan" or "SUV").
