The brain requires daily nutrition to function suitable. If you do not receive them, mental clarity is affected. Signs of reduced mental clarity include low memory, problems remembering specific times or places, and the inability to cope with certain stresses. Vitamin supplements, a balanced diet, adequate sleep and exercise are ways to achieve mental clarity. Before taking any vitamin supplement, check with your health provider to make sure it is safe.
The Alzheimer's Foundation of America advises eating a balanced diet and taking multivitamins with vitamin C. This is known to improve brain health. The human body is unable to make vitamin C and eliminates it through urine instead of storing it, therefore it must be obtained through diet and vitamins every day. In addition, this vitamin is excreted in the urine and not stored. The recommended daily amount of vitamin C is 90 milligrams. If not achieved, a deficiency could result in poor mental clarity.
Vitamin E deficiency impedes cognitive function of the brain, according to Oregon State University, affecting the thought process and its clarity. The recommended daily amount of vitamin E is 15 micrograms. It is a fat-soluble vitamin, which means that it is stored in the liver until the body needs it. This vitamin also serves as an antioxidant that protects cells from damage by free radicals, keeping healthy brain cells.
Vitamin B12 levels in the human body are essential for maintaining mental clarity and brain health. Deficiency of this vitamin can cause disorientation and confusion. Vitamin B12 keeps healthy nerves and red blood cells. Nerves are needed in the brain to have rapid thinking response and red blood cells carry oxygen to the brain. The recommended daily amount for adults is 2, 4 micrograms. This vitamin can be obtained through supplements and diet.
