“Our examine highlights the significance of micronutrient range and the stability of well being advantages and dangers,” says Simin Liu, MD, the senior examine writer and a professor of epidemiology and drugs at Brown College in Windfall, RI.
“Figuring out the optimum combination of micronutrients is vital, as not all are helpful, and a few could even have dangerous results,” he says.
The analysis crew centered on heart problems threat elements, together with blood stress, blood sugar, and ldl cholesterol, and issues like coronary heart assault or stroke.

Specifically, omega-3 fatty acid dietary supplements have been proven to decrease heart problems deaths by 7%, coronary coronary heart illness occasions by 14%, and coronary heart assaults by 15%. Folic acid dietary supplements additionally decreased stroke threat by 16%, and coenzyme Q10 decreased all-cause deaths by 32% in coronary heart failure sufferers.

Coronary heart-healthy diets, such because the Mediterranean weight loss program and the Dietary Approaches to Cease Hypertension (DASH), characteristic antioxidant-rich meals. However research of specific antioxidant dietary supplements have been combined or inconsistent.
“Analysis on micronutrient supplementation has primarily centered on the well being results of a single or just a few nutritional vitamins and minerals,” Liu says. “We determined to take a complete and systematic strategy to guage all of the publicly obtainable and accessible research reporting all micronutrients.”
Extra research are wanted to search out mixtures that enhance somebody’s particular person weight loss program and coronary heart well being, the examine authors wrote.
