Research published in the December 2014 issue of ‘Nutrition’ Journal showed that increased intake of Vitamin B2, B6, B12, and Folate, improved brain function in people over 60 with a foggy memory, and even those with Alzheimer’s disease. Participants completed eight different tests for memory, verbal fluency and word recognition, and all test results improved when given B vitamins. If B Vitamins can improve memory in these people, there is a good possibility they can do the same for your memory.
