Scientists found strong evidence that omega-3 fatty acid, folic acid, and coenzyme Q10 (CoQ10) provided cardiovascular benefits. In addition, Omega-6 fatty acid, L-arginine, L-citrulline, melatonin, magnesium, Vitamin D, zinc, alpha-lipoic acid, catechin, flavanol, curcumin, genistein, and quercetin also showed evidence of reducing cardiovascular risk.
A meta-analysis of more than 884 studies finds omega-3, folic acid, and CoQ10 among the micronutrients that reduce cardiovascular risk.
Healthy diets are rich in antioxidants like amino acids, omega-3 fatty acids, and vitamin C, but exactly how beneficial these micronutrients are for cardiovascular health has long been controversial. Now a new meta-analysis published in the Journal of the American College of Cardiology provides some clarity.
Researchers systematically reviewed a total of 884 studies available to date on micronutrients taken as dietary supplements and analyzed their data. They identified several micronutrients that do reduce cardiovascular risk—as well as others that offer no benefit or even have a negative effect. More than 883,000 patients were involved in the combined studies.
“For the first time, we developed a comprehensive, evidence-based integrative map to characterize and quantify micronutrient supplements’ potential effects on cardiometabolic outcomes,” said Simin Liu, MD, MS, MPH, ScD, professor of epidemiology and medicine at Brown University and a principal investigator for the study. “Our study highlights the importance of micronutrient diversity and the balance of health benefits and risks.”
The findings could be used as the basis of future clinical trials to study specific combinations of micronutrients and their impact on cardiovascular health, he said.
Antioxidant supplementation has long been thought to play a role in heart health. That’s because these nutrients work to reduce oxidative stress, a known contributor to many cardiovascular diseases. Heart-healthy diets like the Mediterranean diet and the Dietary Approach to Stop Hypertension (DASH) feature foods that are naturally rich in antioxidants. However, results from studies of antioxidant supplements have been inconsistent—one reason why this approach hasn’t yet been widely adopted in preventative cardiology.
“Research on micronutrient supplementation has mainly focused on the health effects of a single or a few vitamins and minerals,” Liu said. “We decided to take a comprehensive and systematic approach to evaluate all the publicly available and accessible studies reporting all micronutrients, including phytochemicals and antioxidant supplements and their effects on cardiovascular risk factors as well as multiple cardiovascular diseases.”
The researchers looked at randomized, controlled intervention trials evaluating 27 different types of antioxidant supplements. They found strong evidence that several offered cardiovascular benefits. These included omega-3 fatty acid, which decreased mortality from cardiovascular disease; folic acid, which lowered stroke risk; and coenzyme Q10, an antioxidant sometimes marketed as CoQ10, which decreased all-cause mortality. Omega-6 fatty acid, L-citrulline, L-arginine, quercetin, melatonin, curcumin, Vitamin D, zinc, magnesium, alpha-lipoic acid (ALA), catechin, flavanol, and genistein also showed evidence of reducing cardiovascular risk.
Not all supplements were beneficial. Vitamin C, Vitamin D, Vitamin E, and selenium showed no effect on long-term cardiovascular disease outcomes or type-2 diabetes risk. And beta carotene supplements increased all-cause mortality.
According to the researchers, the findings point to the need for more personalized, precision-based dietary interventions that involve specific combinations of beneficial supplements. Further study is needed, including large, high-quality interventional trials to investigate the long-term effects of certain micronutrients on health.
“Identifying the optimal mixture of micronutrients is important, as not all are beneficial, and some may even have harmful effects,” Liu said.

Someone should market coq10, omega3, and folic acid together as a heart saving pill.

I’m glad I don’t have to pronounce the names of any of the researchers.
Great news. I’ve been taking all of those things for years. At my MD appointment last week, my blood pressure was on the low end of “good.” And I’m 86.
Exercise helps too. A 20 minute walk daily will keep you quite healthy. Treadmill our outside, doesn’t matter. My far-younger neighbor thinks it’s fun to walk outside in the snow. Big sigh.
A one gram dose of omega oil fills an entire large capsule so hard to do that.
Unfortunately most of the study participants died of kidney failure.....others from clogged upper intestine.
Perfect is the enemy of good.
Micronutrients? Like those tiny shrimp they put in eggrolls?
“Omega-6”
Discredited.

Where did you see this, I didn’t see it in the article?
Nothing is credible in medical science thse days.
My guess is someone probably has.
Taking everything on that list (at least most of the time), I have been aware of the possibility, but hasn’t happened yet.

Here’s the chart of findings:

Almost any diet is better than the standard American diet, aka SAD.

Yeh, but that mix blows out your liver! But the heart loves it!
Interesting, but it’s not really clear what the difference between the two yellow triangles is.
