Despite their high requirements for vitamin D, people over the age of 75 might not be getting enough.
study has shown One in five Australians are vitamin D deficient.
In high latitude parts of the world, resembling the UK, About half Don't reach enough levels.
This increased risk of deficiency is partly Lifestyle factorsSuch as spending less time outdoors and inadequate vitamin D intake.
It is difficult to get enough vitamin D from food alone. Oily fish, eggs and some mushrooms There are good sources of vitamin D, but few other foods contain high amounts of the vitamin.

According to a scientific review by the Society, which summarizes the evidence from randomized controlled trials of vitamin D supplementation in humans, Moderate evidence Advising vitamin D supplementation may reduce the chance of premature death.
The society estimates that the supplements could prevent six deaths per 1,000 people. When considering the uncertainty within the available evidence, an actual variety of fewer than 11 deaths could also be of no profit.
Should we be testing our vitamin D levels?
Endocrine Society Guidelines Recommend Routine blood tests to measure vitamin D levels will not be essential for healthy people over the age of 75.
There is not any clear evidence that regular testing provides significant advantages, unless an individual has a particular medical condition that affects vitamin D metabolism, resembling kidney disease or certain bone disorders. .
