Vitamin B supplements may not boost memory

A new study challenges previous findings that increasing vitamin B levels can improve a person's thinking skills and memory.

For the study, published in the journal Neurology, almost 3,000 healthy individuals increased their vitamin B12 and folic acid levels for two years. While the participants did not have vitamin deficiencies, they did have high levels of the protein homocysteine, which has been linked to Alzheimer’s. The participants, with an average age of 74, were randomly assigned to two groups: one group that took B12 and folic acid supplements and one group that took a placebo. Participants’ memory and attention skills were then tested.

The results showed that increasing vitamin levels did lower homocysteine. However, the test scores between the two groups were similar, suggesting that the vitamins didn’t affect memory and thinking as predicted.
