People who take supplements should probably monitor their vitamin D levels. PIC: LEON LESTRADE
Johannesburg - Certain people who take vitamin D supplements to safeguard against diseases and some forms of cancer, could be causing more harm than good, Beeld reported on Friday.
Dr Liza Bornman of the University of Johannesburg's biochemistry department said during a conference on radiation hosted by the Cancer Association of SA that she and her colleagues had conducted their own study.
The researchers examined the ability of vitamin D to repair DNA, and found that in some cases, it lowered the body's ability to fight disease.
Bornman said preliminary results indicated that high levels of vitamin D might impact negatively on the immune system, but not everybody who took part in the study was affected in the same way.
“For now, we have to study the genetic composition of the South African population before anyone takes a clinical standpoint about vitamin D supplements.
“Meanwhile, people who take supplements should probably monitor their vitamin D levels,” Bornman said. - Sapa

This article is of little, if any, value. What level of 25(OH)D had a negative effect on the immune response? What was the evidence of the reduction in the ability to fight disease? If this article is an accurate reflection of what the researcher stated the scientific quality of the study is unacceptable. Testing is essential to determine the proper level of supplementation.
