The best vitamin D supplements
Vitamin D supports immunity and bone health, and most of us fall short in winter. Here is how to choose, and our pharmacist picks.
باختصار
For most adults, a daily 10 microgram (400 IU) vitamin D3 supplement is ideal through autumn and winter. D3 is better absorbed than D2; capsules, tablets and sprays all work.

الأسئلة الشائعة
D3 or D2, which is better?
Vitamin D3 (cholecalciferol) is generally more effective at raising and maintaining blood levels than D2, so it is the usual first choice.
Can I take too much vitamin D?
Yes. Stick to the amount on the label. Very high doses over time can be harmful, so only exceed standard amounts on a clinician's advice.
