Which Supplements Can Improve Your Cardiovascular Health?

Amid the constant buzz about macronutrients such as carbohydrates, fats, and proteins, it’s easy to forget about their smaller, yet equally important, counterparts: micronutrients.

Micronutrients (vitamins and minerals) are vital to maintaining optimal health. We don’t need as much of them (which is why they are called micronutrients), but deficiencies can lead to serious health issues.

But with the overwhelming number of supplements available on the market, it can feel impossible to know which ones can genuinely improve cardiovascular health, and which may be unnecessary or even harmful.

Micronutrients And Cardiovascular Disease

A recent study published in the Journal of the American College of Cardiology has shed light on this important aspect of heart health.

The researchers conducted a systematic review and meta-analysis of 884 randomized controlled trials, involving more than 883,000 participants, to evaluate the impact of 27 different types of micronutrients on cardiovascular disease risk factors and clinical events.

The researchers found moderate to high-quality evidence that certain supplements may reduce cardiovascular disease risk factors:

  • omega-3 fatty acids
  • omega-6 fatty acids
  • l-arginine
  • l-citrulline
  • folic acid
  • vitamin D
  • magnesium
  • zinc
  • α-lipoic acid
  • coenzyme Q10
  • melatonin
  • catechin
  • curcumin
  • flavanol
  • genistein
  • quercetin

On the other hand, the study revealed that some micronutrients had no significant effect on cardiovascular or type 2 diabetes risk:

  • vitamin C
  • vitamin D
  • vitamin E
  • selenium

Surprisingly, beta-carotene supplementation was found to increase the risk of all-cause mortality, cardiovascular mortality, and stroke.

The Most Effective Micronutrients for Cardiovascular Health

The study identified several key micronutrients that had a particularly strong effect on reducing the risk of CVD:

  • Omega-3 Fatty Acids: These essential fatty acids, found in fish oil, are known to decrease CVD mortality, myocardial infarction, and coronary heart disease events. Adding fish rich in omega-3 fatty acids, such as salmon, mackerel, and sardines, to your diet can provide a natural source of these heart-protecting nutrients.
  • Folic Acid: This B-vitamin is crucial for the proper functioning of the body and helps decrease the risk of stroke. Folic acid is naturally found in dark leafy greens, lentils, and fortified cereals.
  • Coenzyme Q10: This antioxidant has been shown to decrease all-cause mortality events. Coenzyme Q10 is produced by the body, but levels can decline with age. Good dietary sources include organ meats, fatty fish, and whole grains.

Helpful Recommendations for Heart Health

Here are a few practical tips to help you make the most of micronutrients for cardiovascular health:

  • Opt for a diverse, balanced diet: To ensure that you’re getting a wide range of micronutrients, aim for a colorful, varied diet rich in fruits, vegetables, whole grains, lean proteins, and healthy fats. This will provide you with essential nutrients, like n-3 fatty acids from fish and folic acid from leafy greens, without the need for excessive supplementation.
  • Consider supplementation with caution: While the study highlights the benefits of certain micronutrient supplements, it’s essential to remember that not all supplements are beneficial for everyone. Consult with your healthcare provider before starting any supplementation regimen to ensure it’s safe and appropriate for your individual needs.
  • Don’t rely solely on supplements: Micronutrient supplements can be a valuable addition to a healthy diet, but they shouldn’t replace whole foods. Natural food sources often contain a complex mix of micronutrients, fiber, and other beneficial compounds that work together to promote overall health and well-being.
  • Stay informed about your micronutrient needs: As new research emerges, our understanding of micronutrients and their impact on cardiovascular health may change.

Stay up-to-date on the latest research and talk to your healthcare provider about any concerns you may have about your micronutrient intake and heart health.

While the findings from this study shed light on the role of specific micronutrients in reducing cardiovascular disease risk, keep in mind that heart health is influenced by a variety of factors.

In addition to focusing on a diverse, micronutrient-rich diet, consider incorporating regular physical activity, stress management techniques, and routine check-ups with your healthcare provider as part of a comprehensive approach to maintaining a healthy heart.
