According to the National Institute on Aging, restoring mental sharpness and preventing future memory decline are connected to how the brain is nourished. A nutrient-rich diet and exercise help maintain brain health.

There are organic vitamins for memory. Rosemary acts as an antioxidant which protects the body against free radicals that can damage the brain and other cells. It also improves the neurotransmitter acetylcholine, which results in improved memory during stressful situations.  The World's Healthiest Foods" website notes that turmeric has anti-inflammatory properties may aid to stop plaque from forming in brain cells. Too much plaque disrupts normal brain cell function. The combination of Ginkgo biloba and Panax ginseng are proven to improve memory.

There are necessary vitamins for memory which can be obtained from the food we eat. Omega-3 fatty acids are an essential fatty acid found in fish oil, nuts and seeds. According to the Mayo Clinic, research has linked the omega-3s docosahexaenoic acid (DHA) and eicosapentaenoic acid (EPA) to a reduced risk of dementia and cognitive decline. DHA and EPA are thought to be essential nutrients for brain function. They can be obtained by eating fatty fish like salmon, mackerel and sardines or by taking fish oil supplements. Vitamin B6 and B12 marketed as memory enhancer. This vitamin is found naturally in fish, poultry, meat, nut and fortified breakfast cereals. The Vitamin B6 functions as maintenance for healthy nerve cells and red blood cells, according to Mayo Clinic. Most people who eat a balanced diet get enough B-12, but deficiencies are common in people with Alzheimer's and vegetarians. For these people, vitamin B-12 supplements have been found to improve memory. A deficiency in it can lead to memory loss and poor brain function.

 A study at Cognitive Drug Research in the United Kingdom combined 60 mg of Ginkgo biloba extract with 100 mg of Panax ginseng extract and gave it to middle age volunteers for twelve weeks. Other volunteers were given a placebo. The group given the combination of Ginkgo and ginseng were found to improve about 7.5 percent on a memory test in the areas of long-term and working memory throughout the study and even after discontinuing the supplement for two weeks. This is a promising supplement to improve memory even in healthy people of all ages.

Antioxidants as efficient for decreasing the free radical damage that can occur with aged people if included in the diet can also help improve memory. Eat fresh, colorful fruits and vegetables for these foods contain the highest antioxidant. Berries (such as blueberries, strawberries, raspberries and blackberries), spinach, Brussel sprouts, plums, broccoli, beets, avocados, oranges, red bell peppers and cherries are some of the best antioxidants food. Make sure to have fruits and vegetables high in antioxidants to nourish and protect the brain. Folic acid has long been considered as an essential nutrient for the brain and spinal cord. Recent research has demonstrated that folic acid has significant importance in Alzheimer’s disease.

In addition, Huperzine A (HupA) and Phatidylserine are known to have memory enhancer particular for aged people. HupA a plant chemical that may improve memory associated with Alzheimer's and dementia, according to the UMMC. The Alzheimer's Association says research suggests that HupA may protect nerve cells but it has not been proven to be effective in treating Alzheimer's. The UMMC warns that HupA should not be used by individuals with liver disease. Phosphatidylserine as a form of phospholipids found in your cells--particularly in the cell membrane and a memory enhancer. For elderly people Phosphatidylserine has been proven to aid memory in the elderly. Theoretically, younger people make all of the necessary phosphatidylserine in their bodies, so the memory enhancing effect is only apparent in elderly people who are under-producing the compound.

Indeed, there are many supplements that will help improve our brain function. Taking the recommended vitamins for memory will really help.
