Rethinking Vitamin Supplements: Health Risks and Balanced Diet

Vitamin Supplements: Health Risks

Rethinking Myths About Vitamin Supplements

Hello everyone, today I’m sharing two authoritative studies on the potential health risks of long-term vitamin Supplements and minerals Supplements . These studies were published in a top-tier cardiology academic journal, the Journal of the American College of Cardiology, or JACC. Let’s delve into the perspectives of these authoritative pieces of evidence.

Vitamins, as essential nutrients that cannot be synthesized by the human body, must be obtained through diet. They are the micro-nutrients required for maintaining normal physiological functions of the body. Vitamins play a significant role in the body’s metabolic growth, development, and are aptly nicknamed ‘vitamins’, the substances that sustain life. Especially now, with the booming voice of health supplements, many keep a stock of vitamins A, B, C, and even wish for a vitamin Z, as if these would somehow make their bodies healthier.

Cardiovascular Health and the Impact of Vitamins Supplements

But it’s important to note, while vitamins are crucial for the human body, the idea that daily extra supplementation leads to health is too naive, too simple. Let’s look into two recent studies by Dr. Jenkins of the Johns Hopkins University School of Medicine and Dr. Michos of the University of Toronto. These top-tier papers bluntly conclude that supplements of vitamins and minerals offer no cardiovascular benefits to the general public. The papers also highlight that over half of the global population takes various nutritional supplements, especially multivitamins, with a high prevalence of vitamin D and calcium.

Promoting a Balanced Diet Over Supplements

People around the world spend a significant amount on these dazzling supplements each year. The authors mention there is still no medical consensus on whether these vitamins and minerals can truly prevent cardiovascular diseases, nor as supplements for the prevention and treatment of such diseases. The only consensus is that a balanced diet is a part of a healthy lifestyle. Dr. Jenkins’ systematic synthesis of years of high-quality research found that multivitamins, vitamin D, calcium, and vitamin C do not significantly impact cardiovascular outcomes.

Most notably, vitamin D supplementation, despite being extensively studied, seems to have no meaningful effect. These quality studies convincingly show that extra vitamin D supplementation does not aid in longevity. Recent evidence suggests that although B vitamins like folic acid and B-complex vitamins can reduce cerebral stroke, niacin in B vitamins can increase mortality rates for various reasons. Dr. Jenkins’ team also found that extra supplementation with folic acid might increase risks of prostate and colorectal cancer.

Navigating the Risks of Excessive Vitamin Supplements

Another paper by Dr. Michos points out that vitamin D supplements offer no cardiovascular benefits. Therefore, the author does not encourage extra vitamin D supplementation for the prevention of cardiovascular diseases, but rather promotes a healthy lifestyle, such as healthy food and moderate sunlight, to balance the body’s vitamin D levels. Dr. Michos’ results also suggest that calcium supplementation can harm cardiovascular health, and extra calcium should be taken cautiously, preferably obtained from fresh food.

Many older adults supplement with vitamin D and calcium, simply believing it would ensure healthy bones. However, recent high-quality research deems this idea unreliable; extra supplementation does not prevent fractures in the elderly, and studies have even found that excessive vitamin D supplementation can lead to more porous bones. Such conclusions are bittersweet, but with such large population data, one can only be convinced.

Hopefully, more people will see these latest research findings and avoid blindly supplementing health products that are useless and harmful to the body. Eating well remains the most reliable way.
