11. Prevents Fractures

Vitamin D helps in increasing bone density, making them harder and more rigid. Its calcium-regulating properties prevent against bone fracture and osteoporosis, a condition common in individuals over the age of 50 whose bones become brittle due to the lack of calcium.
This is why Vitamin D and calcium supplements are suggested in older individuals as a protective measure to protect them from suffering debilitating injuries such as hip fractures.
