Anaemia and Vitamin D

Monday, June 27th, 2011

A recently completed study by Johns Hopkins University has found a link between low levels of Vitamin D and anaemia in children.


Anaemia occurs when the body has too few oxygen carrying red blood cells. Mild anaemia symptoms include fatigue, lightheadedness and low energy. Severe and prolonged anaemia can damage organs through oxygen deprivation.


The study looked at 9400 children between the ages of 2 and 18. The lower the vitamin D levels, the lower the hemoglobin and the higher the risk for anemia, the researchers found.

The article suggests this means vitamin D can protect gums from bacterial infections that lead to gingivitis and periodontitis.

Sunday, May 15th, 2011

A new study publicised in the New Zealand Herald this week looks at the relationship between severe Vitamin D deficiencies and deaths from pneumonia.


The study completed at Waikato Hospital looked at blood samples of the 112 patients hospitalised with pneumonia. They found that the death rate was 29% for those with very low levels of Vitamin D compared to only 4% amongst those with normal or slight deficiencies. While this was an observational study, it suggests avenues for research on whether Vitamin D is a viable treatment option for respiratory diseases.
