Multivitamin Supplements Linked With Lower Cognitive Decline, Better Immunity
More and more cases of cognitive decline are occurring as the world population ages. A recent study suggests that two different supplements - one of ginkgo biloba and choline and the other a variety of antioxidants and vitamin A, vitamin C, vitamin D, and B vitamins – may improve both cognitive functioning and immunity in mature adults.
Participants in the study included 97 non-smoking, healthy older adults. Over the course of six months, one third of the group was given the gingko plus choline, one third was given the antioxidants and vitamins, and the last third was given a placebo.
The researchers administered cognitive functioning tests at the onset of the study, the three-month mark, and at the conclusion. They also measured cytokines (markers of immunity) and growth factors in order to assess inflammation and immune function at the onset and conclusion of the study.
They found improvements in cognitive functioning and immunity in both groups – but with the gingko biloba group in particular - at the three-month marker and at the conclusion of the study.
Researchers from the University of Miami conducted the study. It was published on February 4, 2014, in BMC Complementary & Alternative Medicine.
Previous studies have shown that multivitamins may aid in weight loss, reduce the risk of cardiovascular disease, and boost general physical health. Other studies have also shown that the cells of people who routinely take multivitamins actually have a younger biological age.
