Vitamin D, in its D3 form, is more potent and better absorbed form than its D2 form. Thorne’s vitamin D supplements contain no lactose and no preservatives.

The optimal amount of vitamin D for an individual depends on many factors and varies from person to person. Therefore, the requirement for vitamin D supplementation should be individualized. Either of Thorne’s D-1,000 or D-5,000 can be an ideal way to maintain an optimal level of vitamin D in healthy individuals.*
