Multivitamins&supplements: money wasted, no health benefits shown

Several years ago it was reported, that vitamin and mineral supplements, are in fact useless. There was many follow up studies of the vitamin role with wast majority of them reinforced the thesis. Canadian research team from the St. Michael’s Hospital and University of Toronto have summarized all available data on the use of vitamins A, B1, B2, B3, B6, B9, C, D and E, and supplements β-carotene, calcium, iron, zinc, magnesium, and selenium. The good news – they are generally harmless. The ugly – they do not show any health benefits to their users, at least as a prevention of heart attacks, strokes and early death.

Dr. David Jenkins, the study’s lead author:

“We were surprised to find so few positive effects of the most common supplements that people consume. Our review found that if you want to use multivitamins, vitamin D, calcium or vitamin C, it does no harm – but there is no apparent advantage either.”

The only one vitamin which shows some benefits as a heart diseases protection is folic acid. Niacin (B3) and antioxidants had shown no or small effect.

In the absence of significant positive data – apart from folic acid’s potential reduction in the risk of stroke and heart disease – it’s most beneficial to rely on a healthy diet to get your fill of vitamins and minerals. So far, no research on supplements has shown us anything better than healthy servings of less processed plant foods including vegetables, fruits and nuts.
