No cardiovascular benefits to dietary supplements except B vitamins

According to research reported in the Journal of the American College of Cardiology (JACC) the evidence continued to show no cardiovascular benefits to dietary supplements except B vitamins. No cardiovascular or mortality effects were seen with multivitamins, vitamin D, calcium, or vitamin C in a meta-analysis incorporating 156 randomized controlled trials and meta-analyses. Moderate-quality evidence was available associating folic acid (vitamin and B vitamins with reduced stroke risk,  Niacin was tied to increased all-cause mortality when taken with background statins.

New research reported in the Journal of the American College of Cardiology (JACC). Has found that vitamin D supplements "do not benefit cardiovascular health in the general population and therefore should not be taken for this purpose…Even the benefits of supplemental vitamin D on bone health appear overstated for the general population," The researchers, also found calcium to be potentially harmful. These two supplements, often taken together for bone health, had no heart benefits when looking at the totality of observational and randomized studies such as ViDA and the more definitive VITAL trial.
