Washington, Dec 17 : Supplementing the diet of well-nourished adults with mineral or vitamin supplements has no clear benefit and might even be harmful, researchers have revealed.

The authors of three new studies said these vitamins should not be used for chronic disease prevention, while urging consumers to not "waste" their money on multivitamins, CBS News reported.

Co-author Dr. Edgar Miller, a professor of medicine and epidemiology at Johns Hopkins Bloomberg School of Public Health in Baltimore, told the publication that spend the money on fruits, vegetables, nuts, beans, low fat dairy, etc will protect you long term.

The strong message was based on a review of the findings from three studies that tracked multivitamins link to cancer protection, heart health, and brain and cognitive measures.

The studies were published in Annals of Internal Medicine. (ANI)
