Proper dietary intake is a crucial factor for bone health. Inadequate nutrients intake that is essential for bone increases the risk for osteoporosis by bone loss. The process of the formation of bones requires a constant and adequate supply of the nutrients like magnesium, calcium, potassium, phosphorus, and fluoride.

Vitamin K and vitamin D are very important for strong bones. Vitamin D plays a crucial role in maintaining healthy bone by helping the body absorb the calcium which is essential for maintaining healthy bone density.
