Building strong bones requires calcium and vitamin D3. While calcium helps with the structure and strength of bones and teeth, vitamin D3 supports calcium absorption. Nature's Bounty offers a mineral supplement that is made with calcium, vitamin D3, magnesium and zinc. Nature's Bounty Calcium, Magnesium & Zinc with Vitamin D3 not only provides support to bones but also aids in metabolic, muscle and nerve functioning. Sufficient intake of bone support nutrients can lower the risk of osteoporosis. These tablets can be crushed/cut and mixed with drink/food.
