Vitamin D

Vitamin D preparations in oral forms, stocked across a wide range of strengths from daily doses to higher-strength products taken less frequently.

Before you buy

Strength differences here are large, and a product intended for weekly or monthly use is not interchangeable with a daily one. Some products in this section require a prescription, and the product page states where that applies. Because vitamin D accumulates in the body, the strength and interval should be confirmed by a registered doctor rather than chosen by price.
