Nutritional supplements can’t stave off heart disease

The majority of nutritional supplements or diets are not linked to longer life or protection against heart disease, according to an analysis of 277 clinical trials using 24 different interventions and totaling 992,129 participants.

Although few preventative measures were found to offer some protection against heart disease or death, such as reduced salt intake, omega-3 long-chain polyunsaturated fatty acids (LC-PUFA), and folate supplementation, the study states that these findings are limited by “suboptimal quality and certainty of evidence.”

In contrast, combined calcium and vitamin D may increase the risk for stroke. The study, supported by NHLBI, appeared in the journal Annals of Internal Medicine.
