Vitamin D deficiency early in pregnancy is associated with a five-fold increased risk of preeclampsia, a serious complication during pregnancy which can lead to fetal death, a new study suggests.

Researchers from the University of Pittsburgh Schools of the Health Sciences said the risk of preeclampsia was present even with supplementation of up to 400 International Units (IU)

A recommendation by the Canadian Cancer Society that Vitamin D could help prevent cancer has caused some pharmacies to be completely sold out of the supplement.

An American study found that people who lived in Northern climates did not get enough Vitamin D and that taking supplements can reduce the risk of some cancers by 50 percent or more

The Canadian Cancer Society has advised Canadian adults to take vitamin D supplements to lower their risk of cancer.

Recent studies have shown a correlation between the levels of vitamin D in a person's blood and that person's risk of contracting certain cancers. Those with the highest levels of vitamin D appear to have the lowest risk of cancer

A study involving 1,179 women with an average age of 67 who were taking 1,000 daily international units of vitamin D have been found to have lowered their risk of cancer by 60 percent over four years.

The participants of the study were separated into three groups; 446 women took calcium and vitamin D3 supplements, a similar number got calcium alone, and 288 took placebo pills

A study has found that elderly people who consume high levels of calcium and vitamin D have a greater risk of harming their brains through larger brain lesions. They are also more likely to suffer from cognitive impairment, depression or stroke, the study authors revealed.

Different-sized brain lesions occur quite commonly among healthy elderly people, but the new study found that the overall amount of brain matter affected by lesions goes up with vitamin D and calcium intake, and it's a matter of concern for many scientists
