Each morning, millions of Americans wake up and take a multivitamin. But recently, Annals of Internal Medicine came out with a study saying many who take multivitamins to prevent heart disease and cancer are wasting their money. Experts say there is no evidence of long term benefits.
Despite this report, 80-year-old Wilmer Rensink says he'll still take his daily vitamin.
"It was under doctor's advice that I do that, it is for men over 50," Rensink said.
Rensink takes the multivitamins because he can't get enough nutrients in his diet.
"I eat completely different as an 80-year-old as I did as a 40-year-old," Rensink said.
Sanford Dietitian Jocelyn Johnson says when it comes to supplements, she likes to see a food-first approach.
"By that I mean, we want people to get their nutrients from whole foods rather than supplements," Johnson said.
Johnson says by eating fresh fruits and vegetables, dairy products and whole grains, many will get enough nutrients they need to stay healthy. But, she says, if you take a daily multivitamin, you don't need to stop cold turkey.
"There really has been no research that shows any harm in taking a multivitamin, the only time it can become a concern is if you are taking other individual supplements in conjunction with a multivitamin because there are some vitamins that can be toxic at certain levels," Johnson said.
Experts say there are certain cases where taking a multivitamin is important, like if you are pregnant, over the age of 50 or if you are on a restricted calorie diet.
