Vitamin D Combined with calcium reduces the risk of fracture. The combination of calcium and vitamin D may help older people reduce the risk of fracture, but vitamin D alone cannot work, according to a new British scientific study.
The combination of calcium and vitamin D may help older people reduce the risk of fractures, but vitamin D alone cannot work, according to a new British scientific study.
The study (a review and meta-analysis of 28 published studies) found that people with higher levels of vitamin D in their blood are actually less likely to have bone fractures in the next five to 15 years. However, the same benefit does not apply to vitamin D supplements when they are not accompanied by calcium. No evidence was found that vitamin D alone reduces the risk of fracture. But along with calcium, it has protective action.
The researchers, led by Professor Robert Clark of Epidemiology and Public Health at the University of Oxford, who published the study in the American medical journal JAMA Network Open, analyzed 11 observational observations of older adults. It was found that the higher the level of vitamin D in their body, the lower the risk of heart attack.
Vitamin D is naturally obtained from certain foods, while the body synthesizes it biologically when exposed to sunlight. People who spend more hours outdoors, especially with sunshine, tend to have higher levels of vitamin D naturally in their bodies.
The new study also evaluated another 11 studies that focused exclusively on vitamin D supplements, as well as six focusing on the combination of vitamin D and calcium supplements. The studies had been done on thousands of people from 62 to 85 years old up to a depth of five years.
Those taking the combination of the two supplements were found to have on average 6% less risk of any fracture and 16% less risk of hip fracture, compared to those who did not take any D or calcium supplements or those who had had ).
Millions of people around the world suffer from osteopenia (low bone density) or osteoporosis, resulting in a greater risk of fracture. It is estimated that by the age of 50, about half of women and one-quarter of men will have a fracture in their lives due to osteoporosis. Calcium is vital for bone health, while Vitamin D helps calcium absorption while supporting muscle function to prevent falls that can lead to fracture.
However, as the new study shows, it is unrealistic to expect vitamin D alone to protect against fractures, especially if osteoporosis is already present. To reduce the risk, people need to strengthen both their muscles and their bone mass, which – in addition to calcium and vitamin D supplements – requires regular physical activity, as well as avoiding smoking and excessive alcohol.
