A new study has found that vitamin D supplements are not efficient in lowering blood pressure as prior believed.

The researchers used a random effects model to study the role of Vitamin D in checking blood pressure problem and found no effective benefits in both systolic and diastolic blood pressure.

For the study, the researchers collected data of blood pressure from 46 different medical trials involving more than 4,541 participants who took vitamin D supplements for a minimum of four weeks.

The researchers called this trial a logical one observing that higher blood pressure patients have lower vitamin D levels. However, the results failed and so have several clinical trials failed with Vitamin D before.

According to them, there exists an association between low vitamin D levels and heart diseases or cancer. However, it is not casual.

The National Institutes of Health (NIH) said there is dearth of enough substantial evidence to determine how vitamin D levels could raise the risk or protect against cancer.

According to NIH, presence of too much Vitamin D in the blood can have adverse health effects. Some of the common health problems due to the excess of Vitamin D in blood are constipation, nausea, kidney damage in some cases and many more.

According to the researchers, neither high nor low level of Vitamin D is good for health. Previous studies have suggested that people with low Vitamin D levels could be at higher risk of developing Alzheimer’s disease and die prematurely of cancer or other disease.

97 percent of African Americans and 75 percent of Caucasians have low levels of Vitamin D. This has compelled the doctors to reassess the normal level of this Vitamin type.

The researchers urged for more awareness and in-depth research work in understanding the role of vitamin D- its advantages and disadvantages.

The Vitamin D supplements are the second most recommended vitamin across the country after a multi-vitamin.

The findings of the research were published in the journal JAMA Internal Medicine.
