Benefits of a Multivitamin: Taking a Daily Multivitamin Improves Cognitive Performance, UK Studies Find
According to a series of studies published in the British Journal of Nutrition, Psychopharmacology, and Human Psychopharmacology, researchers found that the benefits of a multivitamin supplement include improved cognitive performance after just a few weeks of taking supplements.
British neuroscientists monitored groups of healthy men, women and children for the effects of retail multivitamin and mineral supplements on their mood and cognitive function. The participants took the supplements daily for four to 12 weeks while researchers measured their cognitive performance with tests that required attention, memory, accuracy and/or multitasking. The participants’ mood and stress levels were also evaluated.
Men who took high dose B-complex vitamins had improved results on cognitive tasks, were less mentally tired and demonstrated more vigor. Women who took multivitamin and mineral supplements had increased accuracy and speed on multitasking tests. Children aged 8 to 14 had increased accuracy in tasks testing their attention.
The co-author of the studies, Professor David Kennedy of the Brain, Performance and Nutrition Research Center at North Umbria University, said, “There’s been a huge research effort into the effects of one or two vitamins on cognitive function, not the effects of many.”
The results of these studies add to the solid evidence that supports the significant and varied benefits of a multivitamin.
Taking a Multivitamin Helps Bridge the Gaps of Any Deficiencies
Unfortunately, experts in the UK and the U.S. estimate the majority of the population is deficient in many vitamin and mineral groups.
“A vitamin deficiency predisposes you to diseases related to having too little of that vitamin,” said Dr. Kennedy.
“The optimum level of a vitamin must be way above what you need to avoid disease. [The survey indicates that] there are people out there deficient in each vitamin group. But since most people don’t know which vitamins they’re missing…you should take multivitamins to bridge the gap and patch up whatever you’re deficient in.”
Make sure you’re getting all the benefits of a multivitamin by taking Healthy Choice Naturals Full Spectrum Daily Multivitamins. It provides a full complex of 56 vitamins, minerals, herbs, foods and critical nutrients for a healthy body, alert mind, strong bones and clear vision.
Omega-3s and DHA Increase Cerebral Blood Flow
Other nutrients have also been found to impact the brain. In a study, published in Biological Psychology, Dr. Kennedy and his colleagues researched the effects of omega-3 polyunsaturated fatty acids on cognitive function. They found that healthy adults who took a daily supplement of one to two grams of fish oil containing docosahexaenoic acid (DHA) did not have improved cognitive function. However, they discovered through brain images that daily fish oil supplementation was associated with increased cerebral blood flow while subjects performed cognitive tasks.
“These results lend support to an emerging body of evidence which suggests that dietary DHA is influencing brain function in physiological terms,” Kennedy and his colleagues wrote.
The finding that DHA may affect changes in blood flow has implications for healthy aging and dementia, Kennedy added.
To get your omega-3s and DHA, take Healthy Choice Naturals Omega Naturals Fish Oil 1000. It provides extra-strength, purified fish oil that yields 420mg of EPA and 280mg of DHA per capsule, so you get 230% more of the beneficial EPA and DHA that your body needs compared to other brands.
