  Cognitive function is affected by many factors, not the least of which is one's diet. While physical exercise and keeping the brain stimulated and challenged are key to maintaining a sharp mind, do not dismiss the importance of what you feed it. Nutrients from food and supplements can prevent brain-related diseases as well as enhance memory and overall function. When considering vitamin supplements to support congitive function, choose strategically.
  
  

Multivitamins

• A comprehensive multivitamin can do more than supplement nutritional needs. For instance, the nutrients in a carefully chosen multivitamin can improve brain function and ward off problems associated with aging, as the brain is affected by so many other functions of the body, such as circulation and detoxification. A good multivitamin benefits the function of the human body as a whole, in turn promoting brain health. Many companies that sell vitamins offer blends designed to support brain function.

  The effects of deficiencies in omega 3 fatty acids on people have been documented extensively. For instance, children who lack omega-3 during their developmental years risk having lower IQs later in life. Additionally, research shows a correlation between deficiencies in omega 3 fatty acids, specifically DHA, dimentia and Alzhheimer's in seniors. Omega 3 can be found in nuts, seeds and fish, and supplements are typically available in capsule or oil form.
  
  

Coenzyme Q10

• After the age of 30, natural levels of the coenzyme Q10 (CoQ10) begin to diminish and by age 80 can be lower than they were at birth. This coenzyme can boost the energy of the brain and heart cells. With its tendency to diminish as we age, coenzyme Q10 is of particular importance to older adults and seniors concerned with maintaining and improving brain function.
  
  

Ginkgo Biloba

• Ginkgo biloba can prevent or decrease the effect of brain damage as a result of a stroke, but in terms of congnitive enhancement, it reduces free radicals and helps oxygen and blood get to the brain. Although studies show that about one of every two users reports improvements, this supplement is worth considering for its effects on memory and reasoning.
  
  

Vitamins E and C

• Antioxidants, such as vitamin C, help cleanse the body of toxins, reduce free radicals and help people feel more alert. In particular, vitamin C supports the transmission of messages through the brain. Vitamin E, which is known to promote heart health and blood circulation, also helps blood circulation to the brain. In addition, vitamins C and E taken together have been found to delay and reduce the severity of dementia and Alzheimer's.
