Supplements are useless for heart

  • Some vitamin supplements can increase risk of a stroke, study finds

"Except to prevent or correct specific deficiencies" corresponding to low vitamin D ranges, or in particular circumstances similar to being pregnant, "there may be a usually good agreement that dietary supplements shouldn't be beneficial to the overall inhabitants".

"This study can help those who create professional cardiovascular and dietary guidelines modify their recommendations, provide the evidence base for clinicians to discuss dietary supplements with their patients, and guide new studies to fulfill the evidence gap".

The overall analysis found that taking these supplements iron did not significantly protect against cardiovascular problems and mortality.

"This research further shows that despite extensive sales and use of different dietary supplements, there is a lack of scientific evidence supporting the use of many supplements", said Dr. Bruce Y. Lee, an associate professor of global health at the Johns Hopkins Bloomberg School of Public Health, who was not involved in the research.

The only supplement to show signs of a negative impact with any sort of confidence was calcium plus vitamin D, which is linked to a greater chance of stroke, according to the study.

In the review, the researchers assessed the data from 277 controlled trials that included nearly 1 million participants. Meanwhile, the researchers also found that dietary interventions with reduced salt intake and high omega-3 intake, seemed to offer protective benefits for the heart.

"Other nutritional supplements, such as vitamin B6, vitamin A, multivitamins, antioxidants, and iron and dietary interventions, such as reduced fat intake, had no significant effect on mortality or cardiovascular disease outcomes."

The 911 call was received around 3 am, and police responded immediately. "Officers spoke to Amber Portwood at the scene". TMZ was first to break the news after the website learned Glennon had filed the official court papers on Tuesday.


While vitamin and supplement use have become the norm for many when it comes to managing an array of health conditions, experts have warned that there's inadequate data about the effectiveness of these interventions when it comes to staving off heart disease or helping people live longer. "Pooling results from all the trials did not support cardiovascular risk. Similarly, the totality of evidence is not consistent for the efficacy of reduced saturated fats".

The findings have been unsurprising, stated Susan Jebb, a professor of diet and population health at the College of Oxford.

"Unfortunately, the current study leaves us with the same foggy conditions that we started with", write the authors of an accompanying editorial.

The authors of the, doctors Amitabh Pandey and Eric Topol, both from the Scripps Research Translational Institute in La Jolla, CA, also emphasize that the quality of the data in many studies assessing the effects of dietary interventions and supplements on heart health can be questionable.

For now, Khan suggests that sticking to a wholesome meal plan may be the best course of action.

"People should focus on healthy diet from nutritional food sources - not vitamins or supplements - in combination with a healthy lifestyle that includes regular physical activity and not smoking", he says.
