Flawed Research Used to Attack Multivitamin Supplements | Novedades Cientificas y Médicas | Scoop.it

Two flawed studies and an editorial published in the December 17th issue of the Annals of Internal Medicine have attempted to discredit the value of multivitamin supplements.1-3

Both of the studies were plagued by grievous methodological flaws.

In one of the studies, subjects were given low-quality, low-potency multivitamin supplements. Treatment adherence rates and drop-out rates were horrendous in the studies. Nevertheless, mainstream sources are using these reprehensible studies to undermine dietary supplements.

The first study examined the cognitive effects of low-potency multivitamin supplementation in aging male participants. 2 Not surprisingly, the conclusions in the present analysis question the value of multivitamin benefits for cognition.

In the other study, subjects with a history of heart attack were given a multivitamin supplement or placebo and monitored for about 4.5 years for cardiovascular events.1

Despite succumbing to heinous design flaws, this study actually revealed evidence that multivitamins reduced cardiovascular risk. However, the investigators constructed the study so as to ignore anything short of miraculous cardiovascular risk reduction, so the conclusion drawn questions multivitamin benefits.

These major gaffes in study design and methodology are not being discussed by conventional sources or the media. Instead, these untoward studies are fueling the mainstream effort to undermine high-quality dietary supplements.
