Vitamin D Could Help Prevent Cancer, Cardiovascular Disease

Consumption of vitamin D supplements do not yield the intended results in preventing cancer or cardiovascular diseases and does little to help the condition of critical patients when taken in high doses, as per several studies published this year. The media highlighted these results that were shockingly contrary to doctors' recommendations of vitamin D as the cure-all supplement.

But the facts are muddied by scientists and journalists, according to Dr. Joseph Mercola in his recent blog that addressed certain gaps in the interpretation of all this data 

During one experiment, participants were administered a daily dose of  2,000 international units (IUs) of vitamin D3 and 1 gram of omega-3 fatty acid, and then compared to a placebo group of healthy participants. The study showed that taking the supplements had not lowered cancer incidence and cardiovascular events. 

Mercola pointed out two factors in the findings of the study conducted by the American Academy of Cardiology published in January of 2019. A dosage of 2,000 IUs is insufficient to achieve the vitamin D level of 40 ng/mL (100 nmol/L), the minimum requirement for disease prevention. 

Research suggested that 10,000 IUs a day is needed to increase vitamin D levels, to be within the ideal range of 60 and 80 ng/mL. The study had not taken into account vitamin D blood levels, which is the correct measure to predict the supplements efficacy, Mercola noted. He described the presentation of the study as perverse and selective. 

Non-profit research organization GrassrootsHealth dedicated to promoting messages on the latest developments pertaining to vitamin D and omega-3 supplements is of the same opinion. They said that when the diseases were sorted into different categories, based on various types of cancer and heart diseases, there were 30 different significant results. 

Even when taking the insufficient dosage of  2,000 IUs of vitamin D, there was a 17 percent lower likelihood of cancer mortality. The chances of cancer mortality had reduced more by 25 percent, when two years of data was excluded from the follow-up years. 

GrassrootsHealth said two things have to be checked in order to determine the accuracy of the study. Researchers need to check the baseline and increase in vitamin D serum level. They also must take note of the vitamin D dosages, intervals and whether D2 or D3 was given.
