Taking high dose vitamin D every month does not prevent cardiovascular disease

A study published in a new issue of the Journal of the American Medical Association cardiology recently said that taking high doses of vitamin D every month does not prevent cardiovascular disease According to the study, a link between vitamin D deficiency and cardiovascular disease has been found, but previous clinical trials (http:// have not observed that vitamin D supplementation can help prevent cardiovascular disease, which may be due to too little vitamin D supplementation To this end, more than 5000 people were recruited from the University of Auckland, New Zealand The participants ranged from 50 to 84 years old, with an average age of 66 years 25% of them lacked vitamin D The subjects were randomly divided into two groups, one on vitamin D and the other on placebo Take 5 mg in the first month and 2.5 mg in each month thereafter After three years of follow-up, the researchers found that 303 people in vitamin D group had cardiovascular disease, accounting for 11.8%; 293 people in placebo group had cardiovascular disease, accounting for 11.5% There was no significant difference in incidence rate of cardiovascular disease between the two groups The participants in the two groups were further divided into subgroups such as those who lacked vitamin D or had a history of cardiovascular disease when participating in the study, and no significant difference was found between the effects of taking vitamin D and placebo Skrag et al concluded that monthly high doses of vitamin D are not supported to prevent cardiovascular disease Tim Chico, a cardiovascular disease expert at the University of Sheffield in the UK, said that many people want to reduce the risk of disease through vitamin supplementation, but there is evidence that it is a waste of time and money, so it is better to eat more vegetables for health (http:// However, some experts believe that although taking high doses of vitamin D every month can not prevent cardiovascular disease, adjusting the dosage, frequency and time can play a preventive role.
