Vitamins For Energy And Memory

People of every age require vitamins for health, and without them symptoms of deficiencies begin to develop. Common symptoms that plague the elderly are lack of energy and reduced memory function, and although vitamin deficiency is not always the sole cause, certain vitamins can work "double-duty" and help to mitigate both issues simultaneously. Vitamins B-6, B-9 and B-12 are involved in both energy metabolism and maintenance of higher brain functions. These vitamins may be obtained via supplementation or through diets rich in organ meats, green leafy vegetables, fish and legumes.

Vitamin B-6

Vitamin B-6, or pyridoxine, is essential for the synthesis of neurotransmitters and hormones used by your brain to function properly. Serotonin, dopamine, adrenaline and noradrenaline all allow communication between neurons in your brain. A deficiency in B-6 and other B vitamins causes reduced cognitive ability, impaired memory function and altered moods, according to "Human Biochemistry and Disease."

Vitamin B-6 is also essential for liberating glucose from amino acids and glycogen -- processes known as gluconeogenesis and glucogenesis, respectively. Because glucose is the primary molecule utilized by your cells to produce energy, vitamin B-6 is considered a crucial nutrient in maintaining energy levels and vitality in your body, as noted by the University of Maryland Medical Center.

Vitamin B-9

Vitamin B-9, or folic acid, is essential for memory retention and the ability to concentrate, especially within the elderly. A study published in a 2007 edition of the journal "Lancet" found that folic acid administered over a three-year time frame reduced cognitive decline and preserved memory function in patients between the ages of 50 and 70. According to the Linus Pauling Institute, folic acid is needed for amino acid and nucleic acid metabolism. The synthesis of DNA, which is the "blueprint" for all cells, is dependent on folate coenzymes. Without healthy DNA, energy production is severely compromised.

Vitamin B-12

Vitamin B-12, or cobalamin, is essential for the operation of higher brain functions, such as cognition and memory retention. Vitamin B-12 is needed for the synthesis of myelin, a protective and insulating fatty-acid sheath surrounding your nerves. The myelin sheath allows for an efficient flow of electrical impulses generated from your brain. Vitamin B-12 also protects your brain from shrinkage, which leads to impaired concentration and memory function, according to the Linus Pauling Institute.

Vitamin B-12 is also needed in the synthesis of DNA and to maintain red blood cells. Healthy red blood cells are required to transport oxygen around your body, which is partly used to oxidize glucose within your cells and produce energy. Vitamin B-12 is specifically involved in the metabolism of fatty acids and protein to derive glucose.
