Vitamin D supplements "no help" to healthy

Vitamin D is necessary for strong bones and muscles, due to its ability to help the body effectively absorb calcium. But a new study from New Zealand found that vitamin D supplements may have no beneficial effect for healthy adults.

Researchers from the University of Auckland conducted a meta-analysis of 23 studies involving more than 4,000 people to examine the effects of vitamin D supplements on bone mineral density. The supplements were taken for about two years by healthy adults.

But the study found that vitamin D supplements are not an effective way to prevent osteoporosis.

The findings do not apply to everyone, however; researchers said that elderly individuals should take vitamin D supplements in addition to dietary calcium as an effective method to prevent fractures stemming from low bone density.

People who are advised to take vitamin D supplements should not take more than 25 micrograms per day, experts said, as taking too much may lead to a build-up of calcium and damage the kidneys.

The majority of people should aim to absorb vitamin D naturally, through sunshine and foods such as oily fish, eggs and certain breakfast cereals.
