New Research Cautions On Dietary Supplements And Periwinkle Extracts During Pregnancy

New research has revealed serious consequences of young people taking dietary supplements sold for weight loss or muscle building, as well as the use of periwinkle extract during pregnancy.

According to, dietary supplements have become more and more popular. A survey conducted by the Council for Responsible Nutrition in 2018 found that three-quarters of American adults take some form of dietary supplement.

The research stated that despite the claims that such supplements could have health benefits or help meet body-building, diet, reproductive, and other performance targets, the products were not regulated or independently tested. The safety and efficacy of many marketed dietary supplements were thus not clear.

The researchers at the Harvard T.H. Chan School of Public Health, Boston, Massachusetts, having noticed the increasing use of dietary supplements amongst children and young adolescents, decided to investigate the effect this was having on their health.

The scientists discovered that almost a thousand adverse event reports were linked with the use of dietary supplements sold for weight loss, muscle building, or energy. Around 40 percent of these had severe medical outcomes, including death.

The risk of a severe medical outcome after taking such supplements was almost three times greater than with vitamins. This supports findings from other studies that have linked weight-loss and muscle-building supplements with stroke, testicular cancer, liver damage, and even death.

“It is well past time for policymakers and retailers to take meaningful action to protect children and consumers of all ages.”

Vinpocetine, which is derived from an alkaloid found in periwinkle, has been shown to be associated with adverse reproductive effects and may cause miscarriage or other harmful effects to a developing foetus.

In their report, the FDA said,

“We are advising pregnant women and women who could become pregnant not to take vinpocetine.

We are also advising firms marketing dietary supplements containing vinpocetine to evaluate their product labeling to ensure that it provides safety warnings against use by pregnant women and women who could become pregnant.”
