How to Choose the Best Vitamin D Supplements
Vitamin D3 (cholecalciferol) is the most effective form for raising blood levels, and common doses range from 2000 to 5000 IU, though the right amount depends on your needs and blood levels. Look for third-party testing, minimal fillers, and a delivery form you prefer, softgels in oil aid absorption, while tablets and gummies offer convenience. Some formulas pair D3 with K2 to support how the body uses it. Because needs vary, ask your doctor about testing your levels and the right dose for you.
Frequently Asked Questions
How much vitamin D should I take?
Common supplement doses range from 2000 to 5000 IU of D3, but the right amount depends on your blood levels, sun exposure, and health. It is best to have your levels checked and ask your doctor what dose is appropriate for you.
What is the difference between vitamin D2 and D3?
Vitamin D3 (cholecalciferol) is generally more effective at raising and maintaining blood levels than D2, which is why most supplements use D3. Look for D3, ideally with third-party testing for quality.
