Study Finds Consistent Multivitamin Use May Decrease Deficiency of Micronutrients
Multivitamins are a combination of many different vitamins, dietary minerals, and other nutritional elements that are normally found in foods, and serve as a dietary supplement. According to a recent study, consistent use of multivitamins may help decrease deficiency of several micronutrients, including folate, iodine, selenium, and vitamins B6, B12, and D.
Participants included 9,901 adults aged 51 or older who participated in the National Health and Nutrition Examination Survey. The researchers used the National Cancer Institute method to evaluate daily consumption of 18 micronutrients. Blood samples were used to evaluate participants’ levels of 18 micronutrients.
When the researchers compared micronutrient levels from food alone and from multivitamin use, they found that consistent multivitamin use decreased the prevalence of micronutrient deficiency. It also improved the status of folate, iodine, selenium, and vitamins B6, B12, and D.
In addition, sporadic and consistent multivitamin use were associated with adequate levels of folate in both obese and non-obese participants. Obese people tend to be at a higher risk of folate deficiency.
The study was conducted by researchers from the George Mason University. It was published online ahead of print on August 5, 2019 in the Journal of Dietary Supplements.
