    Alzheimer disease (33). Regardless of whether or not B vitamins improve existing cognitive performance, if blood concentrations are low, further cognitive impairments can develop. Given the poor food intakes and poor nutrient absorption of this population, supplementation with a MVM would seem prudent. During normal aging and various neuropathologies, there is evidence of increased oxidative stress in the brain (34). Ingestion of known antioxidants such as vitamin C, vitamin E, selenium, coenzyme Q10, n-acetyl-cysteine (NAC),focus formula lipoic acid, flavonoids, and other phytonutrients have been promoted to reduce free radical damage and prevent declines in cognitive function. While numerous animal studies support the above claims, research on humans is more limited. One study indicated that among people aged 65 and older, higher ascorbic acid and beta-carotene plasma levels are associated with better memory performance (35). Another study indicated that decreasing serum levels of vitamin E per unit of cholesterol were consistently associated with increasing levels of poor memory, while serum levels of vitamins A and C, beta- carotene, and selenium were not associated with poor memory performance (36). These epidemiological studies are correlative and other factors may have impacted the findings. Collectively they do tend to support that higher antioxidant concentrations are associated with a higher performance on memory tests. Unfortunately, there is insufficient information to recommend exact
