Taking a daily dose of Vitamin B could help your memory and also could delay the development of Alzheimer's disease, according to a new Oxford University study.

The discovery that the vitamin can help stop brain shrinkage and also help people in the early stages of failing memory could lead to a treatment for the condition.

British researchers say a high dose of Vitamin B supplement combined with Folic acid works best. They suggest taking about 300 times the recommended daily intake of B-12 and 15 times the recommended amount of B-6.

They also say it is important to get about four times the amount of Folic acid. That's because B vitamins control amino acids in the blood. It is the high levels of amino acids that increase the risk for a person getting Alzheimer's disease.

"It is our hope that this simple and safe treatment will delay the development of Alzheimer's in many people who suffer from mild memory problems," David Smith, a professor emeritus in Oxford University's pharmacology department and co-leader of the study, told The Guardian newspaper. "About 1.5 million people over 70 in the U.K. who suffer from mild cognitive impairment - who have a 50/50 chance of going on to develop full-blown dementia within five years - could benefit from the discovery," Smith added.

Smith said while the results were "immensely promising," it was not yet certain if B vitamins could slow or prevent the development of Alzheimer's.
