Vitamin and mineral supplements taken by millions could increase risk of heart disease

Millions of people who take vitamin and mineral supplements may be unknowingly increasing their risk of heart disease and premature death, a recent study has found. The study, published in the Annals of Internal Medicine, analysed 277 previous trials involving almost one million participants to assess the impact of 16 different supplements and eight dietary interventions on mortality and cardiovascular outcomes in adults.

Researchers discovered that the majority of these supplements, including popular choices like multivitamins, vitamins A, B6, C, D, and E, and iron tablets, did not provide any significant protection against illness. In fact, some combinations like vitamin D with calcium were found to potentially raise the risk of stroke rather than reduce it, as reported by Surrey Live.

Dr Safi Khan, the lead author of the study from the University of West Virginia, highlighted, “We found out only a few of the 16 nutritional supplements and one of the eight dietary interventions evaluated had some protective effect in cardiovascular risk reduction.” Despite this, fish oil supplementation was found to be protective against heart attacks, and folic acid supplementation was found to be protective against strokes.

Contrary to popular belief, specific diets like the Mediterranean diet and vegetarian diets did not show any significant impact on heart health in the study. Reduced fat and saturated fat intake also did not exhibit positive effects on cardiovascular risk. The researchers only noted beneficial effects from a reduced salt diet, which lowered the risk of death in individuals with normal blood pressure, and a diet rich in omega-3 fats from fish, which protected against heart attack and coronary heart disease.

The research raised questions about the effectiveness of supplements in promoting cardiovascular health, as noted by researcher Dr Eric Topol, who highlighted the influence of geographic factors on study outcomes. The confusion surrounding the benefits of supplements versus a balanced diet was emphasised, with dietary modifications having limited impact on heart health in the study.

In conclusion, while many people rely on vitamin and mineral supplements for their perceived health benefits, this study suggests that a well-rounded diet rich in essential nutrients may be more beneficial in preventing heart disease and improving overall health.

Insights and Summary:
The study’s findings shed light on the potential risks associated with indiscriminate use of vitamin and mineral supplements, urging individuals to reassess their reliance on such products for health benefits. It underscores the importance of a balanced diet in promoting cardiovascular health and overall well-being.
