Nature Made Vitamin D3 1,000 IU (600 Softgels Twinpack)

Maintaining healthy levels of vitamin D in your body has been shown to be an important part of overall health. Vitamin D supplements come in two forms: vitamin D2 and vitamin D3. Vitamin D3 is more effective at raising and maintaining adequate levels of circulating vitamin D in the body. Vitamin D3, the body's preferred form, is used to formulate Nature Made's Vitamin D Softgels.
