A new study led by experts at Harvard University of America found that people who took vitamin D supplements on a daily basis may be less likely to develop late-stage cancer and even killer cancer, and researchers found that people who ate daily pills were 17 percent less likely to develop advanced cancer. % And those of a healthy weight were likely to benefit, with a reduction in risk of 38%.
According to the British newspaper “Daily Mail”, researcher Dr. Paulette Chandler, a primary care physician and epidemiologist at Brigham and Women’s Hospital in Boston at Harvard University said: “Vitamin D supplementation is readily and cheaply available and has been used and studied for decades and the results we have reached, especially the strong reduction of the risks observed in For normal-weight individuals, it provides new information about the relationship between vitamin D and advanced cancer.”

More than 25,000 people participated in the study, which spanned over five years.
Among the participants were men 50 years or older and women 55 years or older who did not have cancer at the start of the trial.
The test subjects were divided into four groups – the first group took a daily dose of vitamin D and omega-3. The second group took vitamin D in addition to a placebo, while the third group took omega-3 in addition to a placebo, while the fourth group took only placebo drugs..
Initial results showed no statistical difference in overall cancer rates, but a decrease in cancer-related deaths was noted.
In their secondary analysis, Dr. Chandler and colleagues assessed the risk of developing advanced cancer – late stage and metastatic forms of the disease – among participants who took or did not take vitamin D supplements during the trial..
They also examined whether an individual’s BMI played a role.
Among the participants, 1,617 people were diagnosed with an invasive form of cancer – such as breast, prostate, colon, rectal, and lung cancer – over the next five years..
Among those who received vitamin D, 226 were diagnosed with advanced-stage cancer, compared to 274 who received a placebo..

Of those at a healthy weight who took vitamin D, 58 people were diagnosed with advanced cancer compared to 96 people who took placebo..
The team said they found no association between omega-3 fatty acid supplementation and advanced cancer.
Researchers believe that obesity and the inflammation associated with it may reduce the effectiveness of vitamin D..
Dr Chandler said: “ Our findings, along with results from previous studies, support the ongoing evaluation of vitamin D supplementation for the prevention of metastatic cancer – a biologically plausible link..
Additional studies focusing on cancer patients and investigating the role of BMI are warranted.
Like Harvard University, most research on vitamin D and cancer shows a link between people who get enough vitamin and have lower rates of disease, less severe cancers and a reduced risk of dying from the disease.
In laboratory studies, pitting vitamin D against cancer cells has been shown to reduce their growth and prevent them from multiplying and spreading..
