Researchers say that elderly people with a mild memory loss may feel much better after taking very high daily doses of vitamin B to slow the rate of brain shrinkage.

A study done by the University of Oxford found that consuming vitamin B tablets every day can reduce the rate of brain atrophy in older people with mild cognitive impairment by almost half.

In the US one out of every five people more than the age of 70, have mild cognitive impairment (MCI) in which they experience problems with memory, language, or other mental functions.

Despite the symptoms not being serious enough to interfere significantly with their daily lives, almost half of them will go on to develop dementia mostly Alzheimer's disease within five years of diagnosis.

Some of the B vitamins like folic acid, vitamin B6 and vitamin B12 control levels of the amino acid hemocysteine in the blood. Higher levels of this particular amino acid are linked with an increased risk of Alzheimer's.

The tablets that were used were nothing compared to the ones you might purchase in a supermarket or pharmacy.
