A new study released yesterday shows Vitamin D can help lower the risk of bone fracture, but in order for the vitamin to be effective you have to take a very high dose.
Research in the New England journal of medicine re-analyzed 11 clinical trials.
They included more than 30 thousand people, older than 64.
According to the food and nutrition board, people older than 70 should consume 800 units of Vitamin D a day.
Taking less than that had no effect on bone-fracture risk.
When the participants took the recommended dose, their risk of hip fracture was lowered by 30 percent and the risk of other bone fractures by 14 percent.
People can also get Vitamin D from nature. It's in many fortified foods, and sunlight spurs the body to produce the vitamin.
