Numerous studies on the effectiveness of Vitamin D in supporting bone health have been done. Results of these studies have shown that vitamin D alone, or in combination with calcium, is effective in supporting the bone matrix and maintaining healthy bone function. Studies also show that a good Vitamin D level reduces the need for high calcium supplementation in supporting bone health.
